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.

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

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.
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.

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.

HP webOS SUPPORT"
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.

This morning I restored a nandroid backup of CM10.1 onto my Nook HD+. After the restore, it went through the standard update from the Play store for all the apps that had been updated since I created the backup. Sometime after that, the screen turned off as you'd expect. The next time I tried to access the device, the screen wouldn't come on. At first I thought it was just the smart cover issue, so I closed the cover and reopened it, but no go. Then I tried to press the home and power button a few times to see if that might be it. Again, no go. Then I tried holding down the power button for 10 seconds to force it to turn off so I could restart it. You guessed it, no go. Then I tried the hard reset trick of holding down the power and home buttons together for 20-25 seconds, and still no go. I'm out of ideas! Any thoughts?!
I bought three HD+ and gave one to my sister. She ran into similar issue (didn't know how she got to that point).
I tried in vain to get it to power up again and was seriously consider to RMA it.
I plugged it to the charger and tried multiple times .... then after leaving it on the charger for awhile and retried .. it powered up again
and has been fine since (I suspected my sister drained the battery completely).
Good luck.

Thanks for the info. Mine is showing as fully-charged. I think my next step is likely to leave it *unplugged* in hopes that it fully discharges so that I can plug it back in and power it back up. I really wish there were some easy way to do a battery pull on this device...
Hey Guys
I installed ARHD 41 a few days ago and everything was working fine. But since yesterday I get some random shut downs when my phone is in my pocket. When I pull it out its dead. No way to get it back on without having a charger around. When I plug it in, a few seconds later the notification light goes on and I can start the phone with the power button.
But just an hour ago it happened while laying on the table and now even the charger way isn't working. No charging light when plugged in, no response on PC or Mac.
Any tips around?

I got it started by holding VOL UP + DOWN, plugged the charger in and then pressing the power button.
Multiple reboots were possible. :good:
But after I pressed the power button to lock the phone, it was dead again
No success with the combination above.
Guess I have to try another ROM when I get it back on somehow

Now its completely dead. nothing work, no LED, no flashing buttons, nothing
