Okay, first thing to mention is that I have searched for information on my issue and while I have found (and tried) solutions that approach my goof, I need to post this:
Last night I finished reading from Kindle app, hit the power button to shut off the screen and laid it down. I know I should have plugged it to recharge but too late now. I am running CM nightly from 07172012, so I know I didn't download the nightly CM battery issue versions.
This morning the screen will not light up; I have tried charging it, hard reset with power and home screen buttons for 15-20 seconds (and longer), and nothing works. My concern is that the screen is dead. I connected the touchpad to my laptop and I get the connection sound from the laptop; it sees the TP but does not accept it as a portable storage device. Device Manager lists it as: QHSUSB_DLOAD with driver(s) not loaded.
When I try the volume rocker button I do not hear the small audible ping as volume goes up or down. Of course, with the resets, who knows where I am in the OS (or even if it is WebOS or Android).
I really didn't want to be a noob and post this, but I need some advice from the brethren here on XDA. Thanks in advance.
It seems to me that it's not even booting if your getting that strange device in device manager. Try the webos recovery tool from hp. It may help. Although it will wipe android off.

my son-in-law is in the same boat. Nothing he does wakes it up. I believe there are tp's out there with this hardware issue. I let my tp battery drain completely. It powers down around 4% battery. I place it on the touchstone, it charges backup and boots into moboot, then webos. I've done this twice. no problems. If it's under warranty still, send it in.
If you have a touchstone charger put it on that and leave it for a couple of hours and it Will come back to life.
See this article by Reverend Kyle http://www.reverendkyle.com/index.php/articles/146-hp-touchpad-charging-issues-solution
I hope this helps.
I've had multiple instances of black screen of death failure.
The latest one I had, I was able to restore by using a standard USB to micro USB cable (and recently NOT the HP OEM cable) to connect to the computer I usually use to sync or use HP web doctor with.
Same symtpom as the OP, get the three dings when connecting the touchpad to the computer, no responses and the QHUSB driver load error. HP charger wouldn't chage it, touchstone would not charge it.
Anyhow, I left it connected for a few hours to charge connected to my PC. Then, I disconnected from the PC using the large USB connector and reconnected. Whamo, got to the bootloader.
I believe what happened was I trickle charged the touchpad enough to get the touchpad to boot.
You can try the various hard boot keypresses too, but wait for a few hours while trying to trickle charge the touchpad via the computer USB.
Update
Okay, so I followed the old rule of doing the simple (and/or free) solutions first and then move on.
1) I set the touchpad on the touchstone for several hours yesterday - no luck
2) I connected the touchpad to my pc through the USB and let it charge - no luck
3) I let it be plugged into the standard charging plug all night - no luck
4) I prayed to the great old god Cthulhu - no luck
My only option remaining is to use WebOS Doctor. One question on that: in all the literature I have read thus far (and perhaps I am mistaken), I need to be able to get the TP into USB mode to download the corrections/reboot back into WebOS. Is that right or can I expect that when the doctor sees the mangled mess of an OS through the USB connection, it will know what to do?
Again, as always that for the previous posts and for the support.

Another piece of black magic that worked for me and is worth a try as it is free. Connect Touchpad to standard HP brick charger plugged into power outlet. Unplug cable from charger, count to 5, plug it back in, count to 5, take it back out. Repeat the cycle until you get bored or until you get a red charging symbol. If you get the latter then let it charge up normally and you are back in business. The theory behind this method is that it takes a few seconds on plugging in for the circuits to realise they "shouldn't be charging" and this allows a little bit of charging to take place on each insertion. Repeat enough times and you get enough to kick start the proper charging. In my case about 20 times did the trick.
As I didn't want to get into this situation again I then set up a Tasker process to power down th eTouchpad if the battey charge dropped below 8% and I've been OK since.
RIP Touchpad / EOT
Well, I had to wait a day to get my hands on a WinXP laptop; I upgraded my Dell to Win8 about 3 months ago and WebOS Doctor does not play well with Win8.
While that time passed, the touchpad finally gave up the ghost. There is no power left in the TP. When I run WebOS Doc the laptop cannot see the TP connecting via USB. I also checked by connecting the TB to the Dell, since it would at least see the device. Not any more.
My thanks again to those that responded. I did try the plug in, plug out with 5 second waits between, just in case. You never know. However, after 50+ attempts I had to call it a no-go.
does your home button light come on at all? Are you able to see moboot bootloader at all or are you able to start the tablet in webos recovery mode by holding the vol key while powering it on? are you able to ./adb connect? Also I've never had much luck with the resest method youre using, holding down the power and home key, I always hold down the power key and press the home key 15 times, when I get hard freezes and lockups, it's always worked.
Mine is in the same boat for a couple of months, removed battery and charged. Boot loader is borked I get only get a qualcomm usb device but nothing thats of any use for webos doctor or qualcomm tools. We'll have to wait until someone figures out jtag or how to replace the bootloader with qualcomm tools. I'm amazed with the number of touchpads out there that something hasn't leaked from hp to fix it. Anyone got friend in hp or qualcomm :angel:
OP Update
Well, I thought this was a dead issue but here is the latest.
After wallowing it a pit of despair the likes of which can only be described as wretched, (I even coveted my wife's TP up close, almost giving into temptation and swapping decals to reverse ownership) I looked outside of XDA and did general Google searches and happened upon this site:
http://forums.webosnation.com/hp-touchpad/299256-dead-touchpad.html
After reading a bit I realized that the touchstone may be able to recharge the dead battery even though fully drained. I began the quest that Friday morning the 24th of August, after verifying that my Dell laptop did not see the TP when plugged in via the USB cable.
I just did a quick check and the laptop now "sees" the TP when connected. Still no luck on booting into Moboot or the USB icon screen - neither Power and Volume Up or Power and Home buttons achieve anything. But I am glad to see that the touchstone has placed enough charge into the battery that the laptop is aware of the TP when connected.
I believe that given a few more days on the touchstone I should be able to boot into moboot.
@ haxin - I have nothing. Not a single light from the Home button - my only evidence that there is SOMETHING going on is when I connect the TP to the laptop and get my connection "sound". Again, I have high hopes that the touchstone will get me where I am going, albeit at a snails pace.
@ paddy - Yeah, I hope that when (if) I get to a lit screen, I am able to move past where you are at. My big concern is that I am toast even with a semi charged or fully charged battery from the touchstone.
I will update later on. Again, thanks to all for the input and probing questions. You have made me think harder and work a bit longer on this project.
OP Update - 31 August
After 7 days on the touchstone, the touchpad is currently showing the low battery charge icon; I have now plugged it into the A/C adapter.
Each morning I have picked up the TP, held down the power button and held the home button for 15+ seconds. Today it worked, turning on the screen for the first time in a week and letting me see the low battery image.
In my quest to resolve this issue, I have read so many variations on what buttons to hold and how long to hold them that after awhile you end up considering the possibility that SOME of the button options are not correct. That the operator has booted their TP up, but they misconstrued the actual solution; how else can you explain the idea that HP built so many different button combinations and hold times to boot a TP from a nearly or fully dead battery state?
Anyway, I will continue to post updates until my beloved TP is back to running CM9.
And to all those who gave their TP up because the battery got too low; find a touchstone or other "trickle" charger solution, connect and let it sit for a week or so.
Thanks!
Glad the Touchstone worked for you , don't know why it has taken so long to charge but when your up an running properly Llama is a good app to install as
A:You can set alarms for when the battery gets to a certain level/levels
B:Have it shut down when the battery gets to a certain level.
I use 20% for an alarm and 10% to shut down which allows me to sleep easy and not worry if someone else is using it . .
I am up and running. I most definitely will load that app on my TP, plus my wife's and a coworker who bought a TP because of mine.
I don't know either why it took so long; I am just glad it worked and I have it back. I am on it right now.
Thanks again to all who provided feedback and guidance. This is why I love XDA.

HP Touchpad sleeping and will not turn on
Just a note to those HP tablet owners who experience the Black screen of death or sleep of death.
I am the proud owner of 4 HP tablets and two of them so far have had the black screen of death. I have read forum after forum trying to get answers to this problem. There was only one posting that has made cense to me. Someone posted that the tablets symptoms are very much like when the Phones use to go to sleep. The solution was to disconnect the battery for a few minutes then plug it back in. Then simply hit the hold the power button down to turn on the tablet.
The problem is taking the TP apart. There is a video on youtube on how to disassemble the tp. It is a little annoying that you have to go to such lengths to reset the hardware but HP will charge you 250 dollars to fix the problem. After you watch the video on how to open the TP, remove the 3 little screws holding the battery. Now slowly pry the battery up, they use double sided tape to hold it in place along with the screws. Wiggle the battery side to side and try to disconnect the battery connector. This can be done without removing the boards in the TP. Wait 1 min then try to replace the connector in the socket. It is on the underside of a board so when you have it in place use something to make sure it is tight. Plug the charger in to the USB cable. Without closing up the unit hold the tablet power button in until you get the battery charging symbol on the display. Let the unit charge while it is still disassembled. Just in case you have a problem. Once everything is operating disconnect to charger and replace the battery screws, now snap everything together.
This was the only way I was able to fix two of my four TP's. I am sure I will have to do this again because my kids always let the tablets go dead and they don't pay attention when placing them on the Stone for charging. If the tablet is not properly placed on the stone the tablet will not charge.
Hope this helps.
This by far is the best tablet for the money anywhere.

I realise this is an old thread, but I recently had a reoccurrence of the black screen of death issue and thought given the number of touchpads still out in the wild, I would share my experience on the off-chance it may help somebody.
My first experience of the black screen issue was a few months after having my touchpad (many years ago). The screen just went black and no combination of holding the reset keys for any period of time would restart the unit. I had suffered lock-ups before and found the reset combination to be successful, but this time none of that worked and I had effectively what appeared to be a dead unit.
Having contacted HP, I returned the unit under warranty and a unit was returned working. I say “a unit” as I was never quite sure if it was the same unit or a refurbed unit, but to be honest given the speed the units went out of stock during the fire sale, I was just glad to have a working unit again.
Well this week after several years of use including the installation of Android, the black screen occurred again. As before, no combination of the keys / holding for a period of time / pressing them a number of times etc had any effect. The unit was three quarters charged and I was using it up till the point the screen went black. :crying:
Given that the unit has no warranty and it was “dead” anyway, I decided to take it apart. Despite watching YouTube videos, this appeared to be more troublesome than I thought, but eventually I was in. Interestingly, the backlight on the screen was still lit, suggesting the unit was still powered. I did consider disconnecting the battery, having removed the screws as per the previous poster, but mine seemed to be well and truly stuck down and I felt I may damage it prying it away from the base.
However, looking around inside the unit, I spotted what was clearly a surface mounted switch that faced upwards towards the back of the screen. Out of interest, I pressed on this switch with my finger nail and my unit powered off (shown by the backlight turning off). I then pressed the normal power switch and the unit powered up as normal. I have attached a photo of the switch which resides close to the popout tab with serial numbers on that can be found on the right hand side of the unit.
It does appear strange that HP put this “reset” button inside the unit, facing inwards rather than outwards where a small hole in the back of the case could be used to press it. So if you do get to the opening the case stage, consider this as an alternative to prying the battery loose. Also if somebody can work out a way to make the button accessible from outside the case it might be a useful modification.

Oh I was so keen when I came across this post. A Reset Button! How great would that be?
Tried it, unfortunately it did not resurrect my dead as a doorstop TP. I was so hoping...
I just put a 'new' EBay battery in it a couple of days ago and tried trickle charging with a 1000mA charger for 24hrs. No joy there either.
All I get when I plug it into the PC is that it shows up as a "QDLoader 9008" (QHSUB_DLOAD driver) .
No flicker of life or light whats so ever...

Try to borrow a Touchstone conductive charger if you can. It's the only thing that has worked for me when it has totally drained down.
All the best.

That's what I was thinking - no joy there either... It is not even showing signs of getting the least bit warm.
I keep thinking and hoping that there is some way to resurrect this one but I may be wrong...
It's currently trickling on a 1000mA charger. Tomorrow I'm going to try the Touchstone behind it.
If that doesn't start something then I'm going to yank the new battery and along with the old battery charge them like an RC device.
(if I can ascertain the proper way to do that --- )

After several days on the trickle, still no life.
Took it apart at lunch and with the battery still connected to mobo it is showing 3.1V across the red/black. So I figure the battery
is good. Looks like the mobo is gone.
Not sure what else to try.

NOTE - I added this post here thinking the CM9 experts could help. I then realized it should be in the Q&A section. If this does not belong here, I ask a moderator to please delete it.
I have been running CM9 nighties for some time now with no issues on my 16GB US WiFi only Touchpad. I installed TWRP and after some time decided to remove it and just use CWM. After trying several things from the posts (which would not work) I decided to remove CM9 completely then reinstall. This is where I got into trouble...
I loaded all necessary CM9 files in the cminstall folder on the Touchpad. I successfully ran ACMEUninstaller and got back to the WebOS language selection (i.e. the initial WebOS screen from factory). Instead of logging into WebOs (felt there was no-need since I never use it), I put the unit in Download mode (vol down + power). I then ran ACMEInstaller2. I received an error (text on the black touchpad screen which I assume is the bootloader) saying the needed files were not installed and something like "remove the wall". I thought I would reboot the unit and now log into WebOS and reinstall the CM9 files (thinking I made a typo when loading them). Now I cannot get the Touchpad to reboot - totally black and even when connected to the PC I dont get the USB connection sound.
Does anyone know if there is a hardware method to bring the unit back (maybe a different sequence of button presses or shorting a pin on the USB connector)? I have tried home+vol up+power, home+vol down + power, home + power, and of course power only and home only. Each combination was held for 30 seconds and then again for a minute and with power connected, PC connected, and nothing connected to the USB port.
Any thoughts would be greatly appreciated.
Resolution: In a post I saw dated May of 2012, the user indicated HP was still honoring their warranty. I contacted HP via their Chat service, after giving them my model and serial number, I was told I had three weeks remaining on my warranty. HP sent me the return box with authorization and in a week I received (what seems to be) my exact Touchpad... only now it booted just fine. I have since reinstalled ICS and am running fine. Thanks to all who responded. I wanted to share this as I am extremely impressed with HP's warranty service (no questions were asked if I had rooted the device, where I bought the device, etc).
I remember this happened on my brothers and what it was is that the battery was completely dead. I believe it has a backup that needs to charge before the main one. That's the only time I have personally seen this happen. Perhaps if you leave it on the charger for a while it will boot and u can use web os doctor to get it to stock.
Live and Die on this day....

Thanks, I let it charge all night then tried it this morning (as described not just powering it on). Of course, with only a black screen I can't tell what the charge is. I have checked the cable and am now using a different power supply in case that had failed. I think because this happened during the removal/install process I scrogged something in the bootloader?

This happened once to my TP when I first put CM7 on the device a while back. I woke up one morning, forgot to plug it in overnight and it had died. No response to any charger, I was getting worried but then I found a solution. With it plugged in, hold the power button and home button down together for 15 to 30 seconds. It was that or hold the power button down and keep pressing the home key over and over. Not 100% sure, but it came back to life and I remember it took me a couple tries. Try holding both down simultaneously for 30 seconds or a minute, if that doesn't work, push and hold power first then home right after and hold both for 30 seconds.
Okay.... hard reset has been a life saver for me. Hold the home button down, then press and hold the power button, so you will be pressing them at the same time. Keep holding them till you see the HP splash screen, it may take a few min and seem like nothing is happening. I thought I fried mine the first day I got it, but this worked for me!
Good luck!
And, if you decide that does not work for you there is such a thing as the WebOS doctor which will get you back to stock. Link here: http://en.m.webos-internals.org/wiki/How_To_Recover?wasRedirected=true

Nope... As stated in the OP, "I have tried home+vol up+power, home+vol down + power, home + power, and of course power only and home only. Each combination was held for 30 seconds and then again for a minute and with power connected, PC connected, and nothing connected to the USB port."
I need to know if ACME Installer is doing anything in the Bootloader. I have flashed and reflashed CM7, CM9, and multiple ROMs. Even uninstalled CM all together when I went from CM7 to CM9. I am familiar with getting into Download Mode and the hard reset (which apparently isn't solving this issue).
I appreciate the feedback, just hoping someone familiar with the Bootloader and Touchpad partitions can help out.

If the battery was low when you got into this state then it could be that there is not enough power to even let the charging circuits work properly. WebOS has better protection against getting into this fix.
I experienced this once and the trick that fixed it for me was to connect the standard micro USB to the Touchpad and use the standard HP charger unit. Then repeatedly remove the big USB from the charger, wait about 5 seconds then plug it in, wait about 10 seconds and repeat the cycle. After about twenty goes I was rewarded with the battery low icon and it started charging again. I think the theory behind this trick is that when you first plug the power in the battery gets a bit of charge before the circuits kick in, detect very low battery and stop the charging cycle. Doing it enough times gets enough charge into the battery to kick start proper charging.
Now I am not saying this will fix your problem but it might be worth giving it a go.
To prevent myself ever getting into this state again indavertently I now have Tasker set up to shutdown the whole device if the battery level drops below 8%.

To prevent myself or more importantly my daughters tablet ever having this problem I have now purchased Tasker as recommend by yourself and others. But cannot yet figure out how to setup an automatic shutdown, if you have the time could you possibly advise how to do it . I have read the guide but am struggling any help would be appreciated.

In Tasker add a New profile and give it a name like Battery_Low
Choose State and then Power for the profile.
In Power choose Battery level and set From to 0 and To to say 8%
Set New Task and do Add give it a name like Shutdown and then pick the Misc category
Choose Reboot and set Reboot type to Shutdown
All done. When battery level drops to 8% or below then Tasker will shut the tablet down. Note it will do this without warning. I think one could probably arrange a pop up warning first but I preferred to keep it simple.

I have tried this since your post - thanks. No luck, but will continue to try. I found a post online with disassembly instructions. I think I may try pulling the battery. Looks rather easy... with the right tools.

The only way I know is to put it on a Touchstone and after an hour or so it Will come back to life. All thanks to Reverand KYLE. His site is well worth checking out.
Hello guys,
I'm new here at the HP Touchpad Section and XDA-Dev Forums.
I am running CM7 on our HP Touchpad and my little brother has been fiddling with it(downloading many apps from the playstore using my personal account, thus forcing me to create a new google account/other shiz).
Then one time, the screen kept turning on and off without us even touching it. Our guess was it was dust on the screen which is being register as touch.
After a week or so that that was happening, the touchpad ran out of battery and was not charged right away.
The result, it won't charge anymore.
Is there anyway to open the device and shock the battery? It may be a dead battery just like what happened to my sister's iPhone.
I've also been reading some charging issues with CM7 and CM9 and tried some of their troubleshooting methods but non worked.
If I just get a little juice to boot it, I would reboot back to webOS as fast as I can and uninstall CM7.
Thanks in advance,
Raphael

Try leaving it on the stock charger for several hours, maybe days. If you have a touchstone, try that.
If you get it to charge (make sure it's fully charged), uninstall CM7 using acmeuninstaller, then boot into webos. If you have preware installed fine, if not install it and download 'remove android' (or something like that). Run it, then install either CM9 or cm10, using acmeinstaller3. There are several good how-to's which you can search for here or at webos nation forum.
When you have it installed, go to settings > storage and click on the 3 little squares on the upper right hand side, and click on usb computer connection. Then make sure the MTP box is checked.
Hope this helps. Good luck.

Thans for the reply chicle_11! Will try that on the weekends since I am very busy with school works. And thanks for the suggestion of installing CM9/CM10 but I will just stick to webOS and get an authentic Android Tablet(I'm choosing between Google Nexus 10 or Samsung Note 10.1).
I use webos at least 50% of the time. It's a shame that there aren't more apps compared to android. You don't have anything to lose by installing android. You'll have an excellent and unique dual boot tablet. CM10 is very stable now, I use it as my daily driver, I highly recommend it.

I still might reconsider flashing CM9/CM10 when I sort out the charging problems since I am just starting to save money for the Note 10.1/Nexus10.
Can you recommend a good CM10-based ROM for the HPTP or just the stock CM10 Jcsullins?
I use/recommend jcsullins' cm10.
Make sure MTP is checked (follow my first post) and that should take care of the charging problems.
Also, try to not let the battery run out of power. It could possibly brick the tablet.
It seems that I have somewhat sorted out the charging problems. I read an article last night that Samsung Chargers also work for the HPTP.
The process is fairly simple. Use the Samsung Charger first to charge a phone. After 2 hours or so, use that charger for the HPTP to charge the touchpad from a used/electrified wire. During the other process, use the HPTP Charger for the phone to power the cord up. After 10mins or so, switch both chargers. So the HPTP should be using the one that came with it by this time.
It worked for a while then the "Please use the charging cable that came blah blah blah to fully charge..." message came. I've read another article that the touchpad should be a little elevated or at least level with the cord so the cord will not fall down that is causing the message to pop up.
I've used both methods and the 2nd method is working like a charm. It shows a battery sign with a lightning bolt and the charging warning/message does not pop up. Will leave it overnight to see if it charges.
Then after, I might reinstall CM9(I've been from CM9 but downgraded to CM7 because of camera issues w/c my lil bro does not like).
So I left it overnight and it charged when I used the 2nd Method. Happy Days!

What?
*fixed*
Sorry, That was late night here in the PHL and was a bit sleepy when I was posting that.
Also have dead touchpad
I haven't been able to see any life from my touchpad after the battery completely drained. Its been 2 days since I haven't been able to use it.
I've tried charging it via the cable and adapter that came with it for a couple of hours, left my TP on the touchstone all afternoon to morning and no life either, the touchpad however is a bit warm at the back. Does that indicate its charging?
my TP is sitting on the touchstone now but I've replaced the AC adapter and currently using my HTC Sensation plug, I am running out of ideas and I'm going to presume its completely dead.........
I've tried connecting it to the pc but nothing happens, Can someone help me out, I've also tried the button combinations "Home, Home+Power and Home+Power+VolumeUp"
I tried both of the methods mentioned a couple of posts ago with no success.
I have also left it on the regular AC charger for 48+ hours and a Samsung cell phone charger for another 48+ hours and nothing.
It is sitting on the Touchstone now for 36+ hours and nothing yet.
I sent HP an email and here is what they said to try:
"We gather from your mail that your Touchpad is unresponsive and will not turn on. To be able to help you with this issue please take note of the following troubleshooting steps:
First of all leave the device on charge with charger for 48 hours after do the following:
Press and hold the power button + Center for 15 seconds. The device may take a few minutes to restart.
Please do the above with the device connected to the charger. (not charging dock nor PC).
Press and hold the power button + volume Up + Center and continue holding for 5 seconds after the Full Erase screen appears.
Also please try the above steps with another USB cable, also please try to connect the USB to the computer with the touchpad, if the computer doesn't recognize the device, the USB cable is faulty.
Please try your charger on another device to see if this charges the device. As the issue could be that the AC adaptor that is not working.
Have you tried another charger with the Touchpad? In order to verify where is the problem. Regarding to your problem ,do you know if the problem is with the charger itself or with the USB cable? Have you tried the complete charger with another Device, phone?
If the steps given do not help you with this issue, please send us a Proof of Purchase (scan of store`s receipt attached to your response) to validate your warranty or the order creation date of your device and your address.
If you need further assistance, please reply to this message and we will be happy to assist you further.

None of that worked either. I just get the "Palm device" balloon on Windows XP when I hold the Power+Volume Up + Center button. It looks for drivers but never finds them.
Also try holding Home + Power button for 30 seconds instead of 15...This has been known to force some life back for some

Nothing after trying that and leaving it on the Touchstone for 48+ hours. Time to leave it plugged up to the computer for 48+ hours and see what happens.
Nothing after 48+ with the factory USB cable connected to a desktop computer.
It would be nice to see a solution that works every time instead of a bunch of guesses.

First my observations on three 32 GB TP's:
My discharge rate on WebOS in Airplane mode was arround -613 to -850mA. Screen on, (brightness affects this).
3. My discharge rate on CM10 in Airplane mode is about -520mA!!
4. A PC's USB port puts out 500mA's!!!
5. On the touchstone, (doesn't seem to matter if WiFi is on or off), with screen on 1/3 brightness + Battery Monito Widget = +853 to 945mA
6. On HP charger & cable, same as above = +1,377mA
What suprised me was the greater drain in WebOS.
You PC's USB port may be causing further discharge to the 2% TP's auto shut-off!
Actually none of these goofy button pressing and charging methods was right. A6 was faulty. It is fixed now.
My TouchPad is dead

My TouchPad discharged overnight and now just has a black screen. None of the button pressing or charging suggestions described in these forums has worked for me. I was just running webOS 3.0.5. No version of Android was on the TouchPad.
Please tell me the trick you used to revive your dead TouchPad. Was it just a problem with your Andriod OS?
Much thanks.

Hey helpful XDA'rs,
After somehow avoiding to have a tablet for this many years, I decided to get a 2ndhand Touchpad after seeing all the reviews, ROM support, price to relative specs, etc... so I bought a second hand 32GB tablet off of ebay. In fact, this one right here... http://www.ebay.com/itm/271192613408?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
Anyways, I got it earlier today, and plugged it into the wall charger it came with (the circular OEM HP one, with the long cable with a silver circle on each end). When I plugged it in, the little white alternating light under the home button switched on, so I figured it was working. Had it plugged in for about a half hour before I decided I couldn't contain my excitement and wanted to power it up. Of course nothing happened. Just a black screen and that little white alternating light mocking me.
I immediately hit up the google machine and XDA and realized that the screen was supposed to be on with an actual charging icon/animation or something like that. Up to this point, I still have not seen any sort of anything appear on screen. Just that little white light. Now yes, I've read through the posts.
First I checked to see if the HP charger/cable would charge my GS2. It did, and quickly (not some sissy trickle charge) and the circular HP thing felt warm to the touch. I also unscrewed the cylinder HP charger and blew in there with my breath pretty hard to clear out any possible dust, then screwed it back on tightly. I have used different cables with the HP charger, and used the HP cable with my GS2 charger. Same results, just that mocking little light, and the HP cylinder did not feel warm to the touch.
I have done pretty much all the button combinations I could find for at least a minute, with no results. Power + home, power + rapid firing the home button, power + volume up + home, power + both volume + home, etc. This is with the charger plugged into the wall.
I did notice two changes though.
#1 When I hold power + home, after maybe 12 seconds, the light stops alternating and is off - for about 2 seconds. Then the alternating starts back up. When the alternating light stops when I do this, it is always for the same amount of time, about 2 seconds, then it starts up again, regardless of if I continue holding the power + home, or if I immediately let go of the buttons, or immediately let go and then try pushing other buttons; it is always the same, the flashing stops after about 12 seconds, pauses with no lights at all for about 2 seconds, and then starts back up again.
#2 When I hold power + home + volume up, after about 12 seconds, the white alternating stops completely and never comes back if I don't do anything else. There are only 3 ways that I have found so far that will get the alternating white light back. First, just simply unplug and replug in, the light immediately comes back. 2nd and 3rd ways are to do the previous two button combos again, (power/home or power/volup/home for about 12 seconds).
MOVING FORWARD, here's where some interesting things happened, which hopefully is enough to have someone knowledgeable know what might be going on.
I decided to try #1 and #2 again, but this time, instead of the wall charger, I plugged the USB cable into one of my computer USB ports. My computer didn't make a device connect sound, nor show any kind of drive being connected in my computer. Just the same alternating white light.
Trying method #1 above, did the same thing. Power/home, alternating light would turn off for 2 seconds then start back up. Still no sounds from computer.
Trying method #2, finally something! When I held power/home/volup, after about 12 seconds the alternating light would turn off for good as expected, but then my computer made a noise! Not the device connected sound (low note to high note sound), not even the device disconnected sound (high note to low note), but that 3rd "device failed to connect" sound, the (three low tone sound). If you go to your windows sounds you'll know which sound I'm talking about. Anyways, I was glad to hear that the computer realized something was there. Although it was just a sound. Nothing in my computer, but for a second I did see a pop-up bubble in my lower right hand notifications say "device did not install correctly" or something like that. Now, with the touchpad still plugged into USB, and the alternating light off, if I either remove the cable (or hold power/home or power/home/volup for 12 seconds so the alternating light goes back on) then my computer makes that "device disconnected" sound. The hell is going on? I can duplicate those two sounds (the device failed to connect sound, and the device disconnected sound) over and over by holding power/home/volup for 12 seconds, and then unplugging and replugging the USB.
Having said all this, anyone have any ideas? Again, up until this point, I have yet to see anything appear on screen. Just that damn white alternating light.
I also know that this might also be a case of the really dead battery. It may just need to charge for like 48 hours via HP wall charger, or it may need to trickle charge for like 48 hours via USB to computer. If that's what it takes, but jesus I'm impatient and don't want to wait a week or longer, especially if I have a small window of opportunity to return this via ebay. So for tonight, I'm going to trickle charge via USB, but with the alternating light OFF via method #2, because at least with #2 and the light off, my computer makes a sound confirming something is plugged in. My rationale is that if it thinks something is plugged in, it will charge it.
Thoughts guys? A million thanks to anyone who actually read this entire essay and is still willing to help out!
Edit: the USB trickle charge I am attempting overnight tonight is via my GS2 cable, NOT the HP cable, since I've read all over the place that the HP cable is of poor quality.
Sometimes, when the battery has been completely depleted, it takes a real long while (24+ hours).
Your cable and charger seem to be Ok, so just plug it into the wall and check on it it tomorrow.
Post again if you keep having problems and we should be able to help you.
Good luck.
Not sure it will help but but holding power,home and volume down button is reboot ,I've had to hold it for 15 to 17 seconds before....

When i got my touchpad it was deeply discharged. I had to let it charge for several hours before it did anything at all. However i used the weak Samsung charger, so there was at least that message "please use the original charger" on the screen. So maybe you just need to wait...
Good luck though
Cheers

To my joy, I woke up today with the screen on displaying a low battery charging icon. It's in the red though, but that's definitely progress. Is there a charging animation, or is it just a still icon? Mine has no animation and wanted to make sure mine didn't freeze.
I wanna say there is no animation just the icon (its been a long time since I've seen it ) but it only needs around 10% to boot... Now that you see the icon try holding the power and home button for 15sec and see if it boots.

I went and grabbed some food and upon returning I saw that my TP had completely turned itself on and was on some sort of setup screen, asking for me to select a language. I'm running through the setup now - two things. First, is it necessary to create a webOS account? Kinda like creating a google account for android? I intend on installing cyanogen10 on this, but wasn't sure if a weOS account was necessary. Or perhaps it's helpful. Second, the touch response is HORRIBLE right now doing the setup, takes multiple attempts to push an area, and with much more pressure than I would think is necessary. I'm assuming this is to low battery,. and it will improve as the battery returns to normal levels?
Not sure about the touch response issue but the low battery could be a possibility , as for the webos account i believe you only need to do that in order to use webos , i would do it anyways though .
Check here if you don't feel like making a webos acct: http://forums.webosnation.com/android-webos/318426-how-install-android-without-setting-up-webos.html

Yeah it was low battery. After a little more charging the touch response works fine now. Thanks! I was really stressing that I received a dead TP.
There are several programs available in the play store that will turn your tablet off when the battery % reaches a certain level. I use Automatelt (thanks to sstar for the tip) set at 20 %.

Is 20% the general consensus around XDA where it shouldn't go any lower than? Are some people setting it higher? Lower?
I have mine at 9% . some prefer more battery left to feel safer i suppose , basically you don't want to let your tp battery drain completely because it might possibly brick

The tablet is dead, it was suddenly. Won't charge or turn on and it's not recognised by the PC. Recovery mode (power button + volume-) doesn't work either.
I know that is not the screen, because the PC doesn't detect the tablet at all. I tried with another battery (my wife has the same tablet), but I had no luck. I also know that the charger and the usb cable are fine.
What else I can do, any ideas or suggestions?

I had the same symptoms after disconnecting and reconnecting battery,I hed to disconnect it for like an hour and then three times try to power on the tablet and it did power on. Maybe your battery is dead so after another hour you may try to use the other battery. If it will work, try to connect the batteries together so the dead one can get a little charge (but do some research I am not sure if it won't have a chance to damage anything) then the same after an hour connect try power on and if it powers on immediately give it a charge.

Just wondered if you had tried this and if so, how you got on? Asking because I bought my daughter one off ebay and it was working fine when I got it, am sure I recharged it once , she played it and then again in morning and thinks she played it till battery ran out. I have since tried charging via pc and mains power, and have disconnected battery twice (case was v. easy to remove so concerned this fault may be reason it was sold), but cannot get a flicker of a response on screen. i got my daughter this as she was desperate for an android tablet for mods for minecraft as I had bought her a Amazon Fire 7 and from what I could see just after xmas, it wasnt possible to root it or sideload at that time, and she said Amazon had no mods compared to the play store and she had been ecstatic with the mods she had found for her android for the short time she had it. I do know when I plug it into the wall charger that the motherboard area gets warm if its been plugged in for a while? Bit of a noob on this stuff,and off sick with probs with my nervous system so my concentration and memory can be a pia. Anyway I was wondering how I can find out if its goosed or what I can try? One of the batterys advertised on ebay is about £50 which seems steep to me, esp. if it doesnt fix it, and esp since I have been unable to work for a few years cos of this illness. I only bought the tablets cos I had extra money after I finally applied and got pip, and got it backdated. Any recommendations for a reasonably priced option for her for her minecraft? Should I go the tablet\notebook type route or can they not handle minecraft? Bit confused by these new notebooks esp touchscreen ones as new ones seem to have small amounts of ram yet are v. popular.
Thanks for advice\thoughts\feedback and let me know if I should start ,y own thread...I only jumped on this to see how he got on and then as I do nowadays with this illness, I then jumped from topic to topic that jumped into my head x sorry x

Firt I would try to trickle charge the battery.
BEFORE YOU DO THIS:
Remove the SD CARD. I forgot to do this and snapped my card straight in half removing the back cover.
This started happening to my ME176 as well but of course not until after I retired it and gave it to my mom.
I would start by letting it sit on the charger for about 30 minutes (since we don't know the current charge state and if the overcharge block is functioning). This will give it a slight charge if dead.
Disconnect charger and remove the back cover and disconnect the battery (as posted earlier). Push and hold the power button a few times even though there is no power.
It may take a few tries of disconnecting and reconnecting the battery before it decides to power up, so keep the cover off while doing this.
Hi
I’m wondering if anybody has any advice regarding my problem. I have looked here and tried what has been suggested.
My stock, never rooted, never flashed, Xperia T (think it was Android 4.3 but can’t now check, the latest Sony rolled out) was working fine until yesterday. I was on a plane and noticed it had 20% battery life left so I plugged it into the onboard USB port. The problem is I think I hay have plugged the cable into the port the work way round – not the connection on the phone, but the actual USB socket. This should be impossible but somebody obviously had broken the port and it turned out the cable could be plugged in both ways! (I don’t know if it was plugged in the wrong way round but is the only thing that could possible explain the sudden death.)
Could this have bricked it? I suddenly couldn’t get a red light to show charging and holding down power on and volume up or down does nothing. I tried charging overnight via a wall socket when I got home but the result is still the same. Just a black screen and no sign of life. I have also tried plugging it into a computer with Sony’s PC Companion but as the phone is not ‘on’, it can’t be found.
Does anybody have any advice where to go from here? I’m more concerned about some recent data from holiday on the phone than the actual handset itself. If the phone is dead, is there any way to read the internal memory?
Thanks
Try this: Unplug the charger, press the power button. The phone won’t power up because there is no charge left in the battery. But press the power button along and while doing so, connect the charger without releasing the button. Now, you will probably see the red light. Please don’t take off your finger from the power button for around 1 to 2 minutes when the red light for charging will glow continuously. If you feel tired holding it, you can try sticking a tape on it in it’s pressed mode. Once you are sure that the phone is now charging the battery again(red light keeps glowing even after the power button is released) kindly wait for 5 to 10 minutes or may be more before you press the power button again to power the phone up. Now the phone will be up and running
If that doesnt work maybe ur battery is dead or usb port broken
Thanks for the advice. I gave that a go after trying a 24h wall charge and not touching it (which did nothing).
So, I held the power down, plugged it in but nothing. I held it down for around 5 minutes both manually and then repeated the process using the rubber band trick to keep the button held down but no red light ever came on. I think I’m going to try a new battery as I genuinely see that I have nothing to lose as I doubt it will be possible for anybody to recovery data given as the phone can’t be switched on so if I break it further I’m in no worse position!
Thanks again for trying to help though!:good:
When I got my xperia t it was in described condition. I also tried everything (rubberband trick and so on) but the only thing working was to open it and pull and put in again the plug of the battery. After that it booted immediately and I got this sleep-of-death-thing nearly every day... Since I soldered the battery as described in this Topic it happens only ~once a week. Good luck!
SOLVED! In preparation for the new battery arriving, I decided to take the back cover off. I unhooked the top battery connector and decided to connect it back up again, just to see if it did anything. Plugged in the charger and a red light came on straight away! I let it charge for a good couple of hours and switched it on – not as easy without the case attached – and it worked. I’m so frustrated with it being such a simple issue as needing to disconnect the battery but even more frustrated with the design that it is meant to be a ‘sealed’ unit with a non-removable battery. I used to often need to disconnect my old Omnia II battery to restart it but that was a simple case of cover off, remove battery, replace battery , put cover back on, not the creaky, back cover fear of cracking exercise of yesterday. Still it’s working now and hopefully life in the old phone yet!
