I recently installed CM7 nightly 12 and it's stuck at this screen. I'm using the stock charger. I've tried plugging it into my computer too.. no luck. Is there anything else to try? Am I screwed?
this sounds like something that was happening to me yesterday. i finally got it to charge by making sure it was completely off. i finally realized that even though the screen was dark it wasn't off, so it never charged (i think it was just recycling the charge enough to keep it on). if you look at it in a dark enough light you can see the screen is still on (backlit).
so plug it in, i would suggest using the wall charger. this usually makes it turn on (at least mine did), once it does, hold the power button until its off, no backlight is on. hope this makes sense and helps out a little
There's many others having this problem (me, on my friends nook, one of them). Hold down the Power button for a long period of time (I heard it's 10 seconds, but someone said they had to hold it for 30) and it will do a hard reset. At that point, try to turn it on again normally. If it doesn't turn on normally, plug it in (using the uSB cable that came with it (that is very important) and into the wall with the provided adapter), wait 30 minutes, and try again. It seems that very few (I don't know if i've actually read of any) who had this problem actually had to return the nook. When it happened to me with my bro-in-laws, he just hed the power button cause he was mad and it turned on, it hasn't happened to him since
Finally started working. I tried holding the power down for awhile with no luck.. Left it charging overnight and tried holding power again and it worked!
Let me start by saying, Power + Home does not work. Yes, really. I know there are a dozen threads about Touchpads not turning on, and they all have "Hold power and home for 20s" as the reply. Please don't respond with "Hold Power and Home for 20s". I have tried it.
Background
I took my Touchpad with me on a road trip. I did not have an official car charger, but I had one rated at 1 amp. I used this charger with my Touchpad, and it said that it was not powerful enough (as expected). I figured I would let the Touchpad at least get some juice while it was not being used. The battery steadily drained over the next couple of days, to the point where the screen did not come on. I assumed this was because the Touchpad was completely drained.
Once I got to a location with an actual outlet I used the original Touchpad wall adapter and let it charge for a few hours. The screen still did not come on, and there was no response (sound/light/vibration) from any buttons. I let the Touchpad continue to charge over night with the same result.
The Touchpad has alpha 2 on it.
What I have done
I have tried:
Power + Home for 15s
Power + Home for 30s
Power + Home for 1min
Power + Vol Up for 15s
Power + Vol Up for 30s
Power + Vol Up for 1min
Power + Vol Up + Home for 15s
Power + Vol Up + Home for 30s
Power + Vol Up + Home for 1min
All of the above with and without the Touchpad being plugged in to the wall and PC.
Trying WebOS Doctor (does not recognize a device)
Trying novacom directly (does not recognize a device)
Letting the Touchpad charge for > 1 day and repeating all of the above
Letting the Touchpad sit on the Touchstone for > 1 day and repeating all of the above
Verifying that the AC adapter is secured properly and repeating all of the above
Changing the USB cable and repeating all of the above
Changing the AC adapter and repeating all of the above
Results
The only time I have gotten any indication that the Touchpad is actually doing something is when using Power + Vol Up (and Vol Down) with the Touchpad connected to the PC. Vol Up has the Touchpad recognize as Palm. Vol Down has the Touchpad recognize as QHSUB_DLOAD. If I have the Touchpad connected to the PC in one of these states, Power + Home will reset the device (and Windows will not recognize it until I use Power + Vol Up/Down again).
That is the only response I get from the Touchpad. Anything else I have tried results in nothing.
My current plan is to attempt to let the battery completely drain, and then charge it again. I was previously under the impression that my Touchpad was out of power, but the testing with Vol Up/Down has shown me otherwise. My hope is that losing all power will truly "reset" the device.
Does anyone have any advice on anything else I should try? Is there a way to recover the Touchpad via booting it as Palm or QHSUB_DLOAD?
Volume Up + Power while connected to PC, then run WebOS Doctor?
You may have done this, but have you tried pressing home first and then holding it and power together? I couldn't get mine to start by pressing power and then home, but when I held home first and then power it came right on. If you have done that then disregard this, but if not I hope it helps.
Another method
Try power and Volume down. Hold for a minimum of 30 seconds before giving up. It has worked twice for me when all else failed.
FishDoc
That was very thorough. Once my TP died completely. I plugged it in and it didn't do anything. When I held Power + hitting home 15 times, it would give mea low battery indicator.
I plugged it in and left it over night. By the morning it was on 100%.

It may not have been clear since it came after the list, but I did try this. WebOS doctor does not recognize the device in any mode. I do not know if this is simply because I lack the necessary drivers when it is in one of the other device modes. On the off chance that I didn't I will try again when I get home.

It is my fault for leaving it out, but I tried this after exhausting the other options.

I really wanted to avoid the slew of "Hold power and press home!" comments and the followups telling me to hold it longer, hold volume, and all of the other normally recommended fixes. I know how to write a bug ticket or two. I'm also the type of guy who posts a followup with what actually fixes the problem (No "nm, fixed it" from me).
It sounds like my current plan of action is going to mimic what you did. I originally thought the Touchpad was getting no power, so I kept trying to charge it. Now I am waiting for it to lose all power, so I can repeat the process after the device (hopefully) resets. I'm not sure how long that will take since I cannot actually use the device to drain the battery.
Thanks for the responses. Some replies are better than no replies.
So i had a similar situation and tried everything you had mentioned and all the suggestions in the thread. Nothing. No power, completely dead. I even left it
overnight on the charger... nothing. For sure i thought I bricked it. Then, I read online that someone tried the following:
Press and hold Power + Volume Up and click the card (menu) button a thousand times.
Wow! It worked! The TP is alive! In actuality, it only took about 30-50 times (not a thousand) of pressing the menu button while holding power + volume up.
I then got the white USB icon in the middle of the screen and then pressed and held the power + menu button to reboot.
What I did find interesting though is the battery was almost discharged even after having it on the supplied charger (not touchstone) overnight.
Anyway, hope this resolves your issue as well.
No go with Home + Power, Power + Vol Down, Power + Tapping Home

Just making sure you read it right since you didn't list it above.
Power + volume up + clicking home button repeatedly.
All 3, same time. Just trying to help.

Well this is a really strange one...
Touchpad was completely non-responsive, I'd tried everything above about 5 times and it just wasn't showing any signs of life. I have left it charging all day today.
Assuming it was completely dead, I sat it down. 5 minutes later, it inexplicably just started booting up.
Wish I knew what I did, if anything to make it boot.
I am having the same issue but what got me there was trying to restore my Touchpad via WebOs Dr. It would restore to like 60% or 80% and then say we were unable to reset your device. It kept failing and no ROM was on my the device anymore. When I hold Power+Vol Up+ Home I can hear my PC detect it but that is all it does.
When I get home tonight I am going to try some of the things in this thread.
But what if I cannot get it into recovery? I read that it is near impossible to brick a Touchpad. How can I still recover without getting into recovery?

not near impossible. I actually bricked mine and had to send it back for RMA.
it got to the point where the hp screen will show, and webos doctor will detect it, but it'll fail when trying to reinstall at about the same percentage as you (maybe less).

Well I installed Android uninstalled it. Then installed it again and forgot mboot then uninstalled it. So I belive I am back to stock but I wanted to upgrade to 3.0.4 then install Alpha 3.5 as I has having problems with the Touchpad rebooting in both Android and WebOS.
So when do I know if it is bricked. And what do I say to customer support to get it fixed? I just bought the Referbed ones off ebay the other day.
Here's an update...
No luck with anything so far. I caved and decided to take the Touchpad apart to disconnect the battery. I did this and still no screen response. The only changes have been it's a bit more difficult to get it into Palm mode (if it does at all), and now it seems that I can get into QHUSB mode just by repeatedly pressing the vol- button (no need to hold anything else). I do not know if the QHUSB thing was like that before disassembly, or if it is a result of me mucking around.
Unless anyone has any great ideas it looks like I will have to hope HP fixes it in order to tell me it is out of warranty for having Android.
If you send it to Hp and If they can't power it on, I'd say they would definitely replace it. Problem is, I doubt they have any more TP's in stock. Not sure how the warranty would work now being that its a discontinued product.
Hopefully after toying with it enough you'll figure it out and get it powered.
Mine is stuck in download mode too. Still no success.
Here's my experience so far.
Black screen.
When connected to PC :
Home + Vol UP - Device Manager shows PALM (with yellow exclamation) - no driver found.
Vol Down (no need to press home or power) - Device Manager shows QHSUSB_DLOAD (with yellow exclamation) - no driver found.
WebOS Doctor fails to detect device (palm ! in device manager)
I tried forcing novacom drivers on the Palm device (both novacom and novacom-bootie) and then running WebOS Doctor, still refuses to enable next button.
Tried connecting with novaterm, cannot find device. (both novacom and bootie driver).
Power + Home for 15 - 20 secs always resets and clears device from device manager.
I installed QHSUSB Drivers.
now when I Vol Down it installs as a com port (Qualcomm HS-USB QDLoader 9008).
I installed QPST_2.7.323 and am able to see the device as Q/QPC-XXX - ESN=*Download* - Phone Number=*Download* - Banner=*Download*.
I tried resetting the device with QPST, fails to complete the command.
I think I need a new boot.hex to flash to the TP, or a way to force it to charge (if that is the problem).
My Touchpad was low on power when I put it away in the car while on a road trip. I plugged it in to the wall the next day when it wouldn't turn on. After charging overnight, it still refused to power on. That's when I started combing the web for possible solutions.
Please stop posting irrational solutions, such as Power + tap home 5,000,000 times as the few times this did work for others, it was merely coincidence, and power + home would have worked also.
Any rational solutions are welcome.
I may just send it in for warranty. Although I bet that at HP, they will just hook it up to a machine with "special" drivers and re-flash it with Web-OS. I wish they would just let me do the repair myself with the appropriate files.
Who knows, maybe it is a hardware issue, but I doubt it.
I'm having the same problems too. What happened on mine is that my webOS was crashing doing random things like watching videos so I figured I'd just reflash the whole thing. I rebooted and went into the webOS recovery and that's when I think I bricked it. All I got was a USB cable symbol and the touchpad was unresponsive. I couldn't make it do anything and I tried all the appropriate button holding combinations and so I let the power run out over night.
Now when I plug it into the wall all I get is a low battery charging symbol. If I hold the home+power button down the screen will turn off after about 20-30 seconds of holding it down. But when I try to boot into recovery by holding the power+volume up buttons, all I get is the same low battery charging symbol. I'll add that I have had it charging for most of the morning so I don't think it is low battery still. And when I unplug it from the wall I get a symbol of two pronged plug that shows for about 5 seconds and then disappears.
Now when I plug it into the computer, I get the low battery charging symbol for a quick second and then it flashes to the message telling me "To reliably charge, use the cable and power adapter that came with your device" in 5 different languages. When I run webOS doctor I get to the screen where you connect your phone to the usb but it doesn't recognize anything and doesn't let me click next. I was able to have my computer recognize the power+volumedown button as the weird Qhusab thing but my computer said it couldn't find any drivers for it. Now I am not able to reproduce that.
I'm not sure what else to try so if anyone has any suggestions, that would be great. Otherwise I'm going to have to try my luck with HP support.

Having the EXACT same problem....anyone have any solutions to this? WHy is this happening?
It's a long shot, but it might help if you are getting to the USB symbol on the Touchpad .
I spent hours trying to connect with no luck with the Touch pad in that state. I rebooted my PC and it connected to the TP right away. (I was using a Win 7 64 bit PC.)
Hello!
ID: C5J8 BIOS: 2.05c
Symptom: if I shut down the tablet from Windows 10 or in Android 5.0 then I can't power on by button.
If I connect the USB cable afterwards it can be powered on random time - sometime after usb cable connect 5 minutes, sometimes more, it is very stochastic behaviour!
My question is: is it bug or feature? The reasen is settings in BIOS or what the hell, I dont understand? I have to tilt my family shut down the tablet, because they can't power on without me...
Do anybody have a good idea?
has nothing to do with windows or android for sure ... when the tab is in the S4 or S5 states the control of the tab is done by the BIOS firmware
1. do a restart/reboot from whatever OS and after that a power off and check whether is responsive now
2. do a forced power off (long press power btn until turns off) and check again
however if it did not show this behavior on your previous bios version then for sure is caused by something in the new bios (i would guess has something to do with the way the battery level is now detected, normally if your battery is below a level it will refuse to start, but if somehow the bios doesn't properly detect that...) maybe you can also try a 'load defaults' in the bios?
Have a look at this thread, it explains how the tablet determines when to turn on.
Dear wallabyman!
Thank you, it is very detailed and good post. I understand, and we can't do anything - it is a feature, but a very ugly feature from Teclast!
This time do you have any change in this operating? Could you power on by button after shut down?
*************************

It has operated in the same way with the original BIOS too!
The reason why I found the linked thread was because I am experiencing some problems too, although not as bad as you describe them.
I am able to always turn on the tablet. If it does not turn on, I am trying the following things (in no particular order):
- Make sure tablet is really off and not stuck with black screen, by holding power buton for 10-15 seconds to do a hard powerdown
- attach a USB lamp to USB-host adapter to see if it is still powered on
- let it charge for about 30 minutes with original charger and original cable before trying to turn on
- not move the USB charging cable too much, my device seems very sensitive to small changes in the USB charging connection. I have the tablet lying flat, and try to power on without touching the cable if it is charging at the same time
- set quiet boot to off in Bios to see the red AMI logo
a minor aspect:
- if the device is charging and I press the power button only once, the Bios boot screen will appear together with the battery, but will not boot until the power is pressed again and battery charge is sufficient
Sleeping:
- putting the device to sleep from Android (sikke1s ROM, not for your device) and waking up again seems to work perfectly for me now.
- with Windows I still have big issues, trying to narrow it down currently
- from the shutdown state I can always boot up within a few tries (press the button not too long or to short, try hard power off even if it appears to be off and again)
Hi,
My HP Touchpad will not turn on. This never happened before. Few times there were some small problems to restart, but I usually do the reboot by holding down the power and the home button and everything was ok, but this time it didn't work. I held it down for 15 and more seconds. I tried to push just power button for quite a while, too. However, it still does not wake up. Usual I keep my Touchpad in sleeping mode, and I didn't let my battery to drain but this time. I switch it off, and I didn't use it during 3 or four days and when I tried to charge it, didn't even recognize that it was being plugged in. The screen is still blank.
I tried to find any solution on the Internet, but everything was not useful.
You guys my last chance!!!
Are there any other ways to fix this?
All help appreciated. Thanks!!!
P.S.
My OS is Android Lollipop 5.1
USB cable is OK is charging my friend HP Touchpad without any problems.
I reset the adapter it means I turn this one way and later back.
I tried my friend charger from his HP Touchpad - nothing.
I left my Pad for few hours plugged - nothing.

One of mine died, I left on charger for I can't remember how long, maybe a week, picked it up and it was on. One other thing to try is pushing the home button 17 times. Good luck.

Thanks, it didn't help, but I'm still waiting for solution. I think that my Touchpad is not broken because before few times something similar happened, and I heard that sometimes when battery is really empty some people had the same problem.
Place on touchstone to fully charge up / boot up?
I have the SM T815 9.7 32 gb variant. It worked completely fine. Two days back i connected a USB OTG and the tab recognized it, but i couldnt explore it inside the file manager, so i fonally diconnected it. Now the tab was charged to atleast a 20 percent. After removing the usb it showed 5 percent. So i connected the 1.8 amps charger i had. It generally charges it correctly and the charge doesnt fall even in use. I started watching a movie. Even tho the charger was connected the charge kept falling and finally shut down. So i left the tab on charge. It was stuck at 0 percent. At first the screen would show whenever i connected it to the charger, but after mutiple tries it has stopped doing that. I tried the stock charger as well, held down the power button and the volume up key for a minute, connected it and then kept holding the buttons for another 30 seconds. Still doesnt work. If i connect the charger now, the screen doesnt turn on or show any signs of charging.
1) connect the tab to PC;
2) press Home, Vol Down and Power simultaneously up to a screen appears;
3) press Vol Down to cancel and reboot the tablet.
Did this. Now the screen shows the charging icon. The chraging is extremely slow, after about 25 minutes its 2 percent. And the battery side is all warmed up. Should i be worried?

srry for reviving this thread but did your tablet eventually went back to normal?
my galaxy tab s2 does not turn on nor charging.. I connected it to my pc and tried home vol down and power but didn't work
And another revival - did you find any solutions to this? - mine did the exact same things, and none of the suggestions worked
Here we are again.
Another device, same problem.
Had around 40% suddenly went black and since then now sign at all no matter what I connect to it or button combo I use.
Edit:
After nearly one hour of testing different combos I could access download mode and from then on everything worked fine.
