[Q] touchpad wont charge/stuck!!!

hello everybody!!!
about 2 months ago i modded my buddy's touchpad for him and everything worked fine. well he brought back the tp to me and saying its stuck and it wont work for some reason. also i am not able to charge with any usb cable it keeps saying
"to reliably charge, use the cable and power adapter that came with your device."
i just want to charge this thing up and remove classic nerd ics from it and simply make it stock web OS cause its become too laggy and glitchy for some reason and i dont know why. well to be honest i havent used it much this is feed back from my buddy.
i just need to get this back to web OS in a couple of hours cause he is a truck driver and needs it on the road. please let me know thanks

In WEBOS it will only charge with an original charger just so uou know..... in Android you can charge with most anything but anything less than 2amps and 5.5 volts is just gonna trickle charge
As far as the Android install it probably just needs an update and clean boot but if you took the time to tead you would find that WEBOS DOCTOR is used to wipe android off the Touchpad

So is the battery dead or are you able to turn it on? The TouchPad needs a certain amount of poswer to charge the device. Thats why the TouchPads original charger has such a big adapter. You chould probably get a slight charge with other chargers but it will take a long time to charge.
As far as android being buggy, I would suggest the same as cdzo72 and just reinstall it. And also like he said, the webOS Doctor will get rid of android. There are also apps in preware, I believe, that remove all traces of android after you uninstall it.

the battery is dead and it wont turn on im trying with orignal hp touchpad charger but there is no power...what to do next ? like its completely black there is no power at all not even a battery sign of charging or anything like that

I'm having the same problem as stated. My battery completely drained. When tried pluggin in it gave me the message "plug in original charger" which I have except for the cable. On the home button I had no chargin light. After a couple of hours I tried turning it on pressing power+home and I got the red battery, then immediately the plug in symbol, then the "plug original charger" message.
Then I decided to plug it to my laptop. The home charging light finally came on stating that it was charging. It's been a couple of hours and I was able to plug it back to the original charger on the wall and the home light continues to show that it is charging. Unfortunately, I've tried to turn it on and I still get the message. I'm going to let it sit for a while to see if it's just not charging fast enough to even power up. I am running CM9. Not planning on going back to WebOS anytime soon. If I get it working, I will let you know.
Oh, if you have the original wall adapter, you can unscrew the actual plug off the adapter by turning it counter clockwise. Then screw it back on. Supposedly that will fix something with the actual wall plug. I don't know if that's what caused mine to actually work again.

If you regularly charge it with a Touchstone charging stand, take it off, and plug it in through the outlet and the cable that came with it, and be sure to try charging in WebOS instead of Android.

Bricked Touchpad need help

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?

It's a good idea to use only stock cable and charger.

No, totally black device. I was hoping at least I'd get the USB connection on my PC, but not even that.

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

This post should do the trick for you....just press the power and home buttons at the same time, hold them down for about 30 seconds until you see the HP logo on the screen then release them...good luck!!!:good:

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.
Thanks

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.

Dead Screen or Nearly Dead Battery Issues

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 --- )
_mr

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.

I'm not sure if my TP is charging...

This is the second time I've had my TP hit 0% battery while in CM9 (relatively recent nightly build) and auto power off and not respond to charging or boot attemps. I can't say for sure which nightly but probably from 6-12 months ago. It's been realtively stable with no problems i could discern. Anyways. Recently, the first time it lost power down to 0% I searched for solutions to the problem. I found the solution, based on the symptoms, to be TPdebrick. I followed those directions to the letter and within a day or two my TP was back up and running after fully charging. I don't recall precisely what occured after completing TPdebrick and the TP booting up again as I had gone to sleep, then to work, had a bunch of other stuff to do after work, then sleep again before I went to check on the TP to use it.
I'm concerned that it isn't actually charging it this time, even though TPdebrick completed successfully. I have tested the USB cable and charger and they are both fuctioning and able to charge my smartphone. The wierd thing is it did charge for a short period of time right after using TPdebrick (according to the output the battery voltage was at 30xxxxx [I don't remember the numbers where I substituted xxxxx]). But not enough for it to reach minimum charge to boot. When after 24 hours on the charger it was still no responsive I thought I'd run TPdebrick again to try and jump start it again so to speak. This time around from the log is the following:
Starting battery authentication...
Battery authentication successful.
battery_info.percentage = 0, battery_info.voltage = 3225680, battery_info.current = 937, battery_info.temperature = 20
This appears to show that it did charge up a little bit from that brief time it began to charge. And that it was recieving a small amount of charge from the PC. Typically when it is charging the cylinder part that plugs into the outlet gets warm. But it isn't getting warm as expected when the TP is connnected. I've also twisted the plug part off and back on several times along with using my smartphone to test that it was able to charge each time. So I'm stuck not knowing if the TP is actually charging because I have no visual or physical indicators that I can determine if it is or not. Any help would be appreciated.

Install the attached file to your touchpad and run it with your charger plugged in. It will tell you if your battery is charging and what current it is receiving.
Just unzip the attachment and install the .apk
Peace

Since I can't boot the TP how do I install that and use it to get the info? Unless there is a misunderstanding. TPdebrick fixes it so it can charge so it will boot but I don't know if it is for sure charging so that it will eventually boot or if I need to use TPdebrick again. Assuming that despite the appearance of TPdebrick having completed successfully running it somehow didn't fix something. I would assume that at this point my options are few. If software means of getting it to boot again don't work I would have to disassemble the TP to get inside and somehow charge the battery up with a crude hand made rig or something. Assuming that the failure to boot is simply lack of charge. As it was the last time this happened. And needed TPdebrick so that it would charge up in that too low state. The last resort option would be get inside it or whatever other method needed to copy the data off of the internal storage (part seen as SD card) in the state it is in. And if the storage can somehow be wiped from there sell it for parts if it ends up not repairable.

It could also be a dodgy Usb connection/board on the TP several people including myself have had this problem.

Well if tpdebrick got it up and running before can you not repeat the process to enable you to charge the tablet. Then you'd be able to install the tpcharge app and go from there ...

Does the back of the TP get warm/hot after charging? On my TP the back area near the volume buttons gets warm after being plugged in for a few hours.

When charging any old day while I am using it I have noticed that area get warm. Just like the cylinder of the charger getting warm almost hot. Neither of that is happening which leads me to believe there may be something more wrong than just the simple yet not so simple problem that TPdebrick fixes. I've ran TPdebrick on it several times now twice before posting the thread and twice after. In completed it's execution with "all done" message. The port itself appears to function otherwise TPdebrick would fail before completing due to a USB connection failure. At least it seems to me it would fail as a result of that. Is there a way any of the parts can be tested for failure to figure out what has failed? Again assuming that something has gone bad internally on the TP. It has been plugged in for now 48 hours only interrupted by running TPdebrick. Of which I could run it again and get the info from the log I previously posted to see how it has changed. I have no idea what the numbers mean other than the battery percent being reported as 0.
I forgot to mention previously that it was plugged in at the time the battery went to 0%. Something I had not expected to occur. The battery icon in CM9 indicated charging with the lighting bolt icon as I had seen the icon just before it auto shutdown. Something I didn't give much thought to as that had happened one time a long time ago when I still had only webOS on it. Except webOS didn't let the battery get too low and it simply booted back up a minute or two after the charger was reconnected after it auto shutdown. So I guess if there is anything I can do to figure out why it isn't charging to know what needs to be fixed and if it is worth fixing and I'm able to fix it then I'd like to fix it. Otherwise I'll need a way to recover the data off of the storage so I can at least not have to start completely over with most of it. Nothing real important on it or anything that if lost would be detrimental just time lost in game progress and related and having to download oddball files for other apps again.

Just out of interest ... my touchpad that was not charging properly thru the usb port still managed to get thru the tpdebrick process to the "All Done" stage. However, it would only take a maximum of 100mA, even off the 2A mains charger. Changing the usb port resolved the chraging issue.
Peace
Edit: also, a touchstone - wireless - charger will eliminate a battery vs USB port fault ...

I have good news and bad news. The good news I'm able to charge my TP with a charger other than the official one. I tried my smartphone charger which is significantly lower amps. In 9 hours it has charged it 30% while it remained in the powered off state. I booted it up a few minutes ago hoping that it had charged it up. I powered it off again and will charge it to 100% before using it.
The bad news is the official chargers cylinder is shot. This is the second official one I have gone through since purchasing my TP during the fire sale. So I'm not sure what I'll do about that. I only really use it as an ebook reader right now and as an alternative to some things I use my smartphone for when I have both available to me. Considering my netbook is in need of replacing due to a failing charging port I am looking to get a windows 8 pro hybrid tablet (ex acer w700) which would effective replace both the netbook and TP. Leaving the TP as a much more of an experimentation device.

mine does not charge in android OS after installing CM 4.1.2 over old cherry kang
im getting current500mA in touchpad chargetest if connected to PC back 2.0 port, charge icon does not appear
charges if on webOS

Having the same issue as serialteg described. Just flashed to 10.2 (09/20 NIGHTLY) and TP cannot charge on CM. Switching back to WebOS, it's being charged.
Fixed. The infamous MTP issue was what I had. Solution found.

Completely dead battery

I know that it has been said that "if your touchpad completely dies, you must have the OEM charger to start it back up". At first this seems true. . .However! I would like to report that twice now, when it was completely dead and displaying the "plug in the original charger for reliable charging or die because im a juice nazi", I was able after about 4 hours of just leaving it alone plugged into a 1amp phone charger, to get it to charge up and boot. This may have already been discovered but I couldn't find mention of it. Just wanted to give hope to someone that might have given up on this.

So when you connect 1 amp phone charger, does the TP says to connect the original charger? Even if it says to connect the original charger, and leaving it for 4 hours the TP charged is that right???
My problem is when I connect to cell phone charger, it says to connect original charger.
When I connect original charger, the TP stays at 0% even after connecting the charger overnight. I dont know what is the problem? is it charger, is it battery or is it TP..

The message will be displayed but it is gradually charging in the background. When it gets enough juice, it will start up and charge faster. In your case it sounds like either your port or battery are damaged somehow. Possibly the charging circuitry but that is unlikely. If you don't have an original charger or touchstone, then your options are limited. They aren't very expensive on ebay though. I would let it charge on a good 1 amp charger for a few days and see what happens then. Mine did the "soft brick" crap once where it was completely unresponsive and ran completely dead and i just charged it for 4 days and forgot about it and when i remembered it, it had powered on and booted. TPs are funny devices. Expect anything and report it if you don't mind. Maybe we can get this sorted out.

Thanks for prompt response..
I have original wall charger, and got a new cable from ebay. So I am hoping its equivalent to original charger. How can I debug if the port or battery is damaged.. any idea?
I left it on charge overnight yesterday. It was at 0, in the morning.. I left it on charge today before coming to office. i am expecting it to be at 0, when I go home.. When its connected to charger, its working normally (with 0 battery), but as soon as i remove from charger, it will shutdown..

Morning, when I was charging,
the battery monitor widget app showing Battery flow as "-600mA". I think this should be +ve while charging. the same app was showing status as "Charging AC plugged". I will try to charge my phone with the same cable and charger, if the phone shows +ve current flow, then, its deffinetly should be problem with the battery or touchpad right..
I wil test it in the evening.. and if its problem with battery or touchpad.. i will try to clean the TP and will try again.. Lets see how it goes

Ok so you have the original charger, great! And it boots into android/webos correct? It sounds like your A6 firmware might have crapped out or whatever it does to cause battery issues. Probably not bad battery if this happened rather suddenly, and its not a bad port if its booting and running while plugged, even if its not charging. . .so go here:
http://forum.xda-developers.com/showthread.php?t=2756314
and read it carefully! With this tool, you can do some really cool stuff including re-flashing the A6 battery monitor/control chip. It can (but might not) fix issues like this. Give it a try with a good cable and let me know what happens. Good luck!

I rebooted to webOS, and TP charged normally.. now i updated to CM11, all good as of now.. Thanks for helping me..
only bad part is i disassembled, before booting to webOS

Aw dude....well hey it happens to the best of us lol. Now u know a lot more about ur tablet and i would still recommend reflashing the A6 and removing webos if u dont use it. Tptoolbox can also be "installed" by renaming the boot image .bin file to uImage.TPtoolbox and placing it in /boot on your android partition. This allows moboot to see it. Off topic i know but i thought you might be interested. Best of luck with the re-assembly!

Because there's not enough room for both, and it's designed to run in the WebOS userspace. Don't even try it; I speak from experience.

Fixed my Touchpad!
I had the same issue and just wanted to report what worked for me. My touchpad wasn't responding to any button pressing combos and even after sitting on the charger for two days, didn't want to turn on. After some google searching I found my Touchpad might be so dead that the charging circuity might not want to charge the battery and all the fixes were telling me to take apart the Touchpad and charge the battery directly. That's not something I really wanted to do. Then another person suggested to charge the Touchpad with a lower amp charger, so I plugged the Touchpad into an iPhone charger for about an hour. I came back, held the power button and home button - nothing. Tried power, volume up, and home - nothing. But then I held the power button and hit the home button ~10 times and then... the home button started blinking left and right. YES! I took the Touchpad and put it on the original charger, 15 minutes later it had the Low Battery Screen and another 15 minutes later, Cyanogenmod was booting.

I need help. When I try to transfer the Android files to the HP TouchPad using TPtoolbox, Windows says that there is an F drive that I have to format before I use it. In the tutorials, a drive labeled HP TOUCHPAD or something like that shows in Windows, and you can put the Android files inside of the ttinstall folder. Should I format the drive and if so, what format?

Oh sorry, I posted to the wrong thread.
