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

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.
I opened kindle fire hd and replaced battery. Kindle was working fine but the old battery would not stay charged for more than an two hours unless plugged in, so I replaced battery. Kindle Fire powered on and new battery stayed charged all day but is stuck at the orange arrow swipe screen. I have done the hard boot by holding power button for 20 seconds and it reboots but still touch screen is unresponsive and also tried with it connected to laptop, no luck.

Is it possible that you unplugged or damaged the touchscreen controller?

I think i know what's going on here, In any KFHD if you charge the device using a wall charger with current output less than 1800mA The touch screen becomes unresponsive while charging, I think that's because the device rely completely on external power source instead of the battery during charging and if this power source is not enough the touch screen doesn't work, I think the battery you put in the KFHD has a lower current output than the original, Try replacing it. Also can you please take a picture of both batteries, make sure the text on the batteries is clear?
Thanks

I am having a similar problem. I had the same problem with the battery not holding a charge, so I bought a new battery. Now the new battery does not power the screen. If I want it bright enough to see, I need to have it plugged in. It started out flickering for a few seconds before becoming clear. After 4-5 days, the flickering doesn't go away.. I'm pretty sure I used the correct charger.
I have a new Motorola Atrix HD. I was using it and the screen went black. i hit the power button to unlock but nothing happened. i plugged it in but nothing happened. i took the back off to see if the battery was disconnected. I didn't know the battery was different than other phones and ripped the power cord connecting the battery to the phone when i took it out. lesson learned. Ordered a new battery and installed correctly. phone won't turn on. The green charge light blinks when i plug it into the wall and then stays on for about 20 seconds and then the phone tries to turn on but while the motorola icon is illuminated, it cuts back out and repeats the cycle. I left it plugged in for a couple hours and still the same thing. i tried holding in power and volume buttons for the boot screen. if i do that just as the phone attempts to turn on i can get the screen up and scroll the list of boot options with the power buttons but i can't select any of them and the phone cuts out after the same amount of time. Everytime. When i plug it into my laptop, the light blinks on and then stays on like with the wall, but the phone doesn't attempt to power up. Please, any help would be greatly appreciated. i have read a lot of forums where the battery was acting up because of the chargers people were using. The difference between my situation and those of the people i read about is that my boot screen cuts out and cannot be used. This all happened 2 days after my exchange period ended and because i took the back off myself, best buy won't have anything to do with me so i'm on my own and cannot afford another phone right now. Thanks in advance for your time and concern.

Is it possible that the that connection between the power cord and the phone itself is loose or damaged? I'm just guessing here as I have never opened up the back of my phone.
I would check your battery terminals then leave it to charge if it does. You could also try a factory cable. Another thing would be to try fastboot while connected to your laptop and see if it stays on, and if it does, try reflashing all partitions.

It was charging for most of the day, so the battery isn't dead. I turned it on and then the screen went black. Now it won't do anything unless I plug it into the computer or wall. I didn't root it or change anything.
I pushed the power button again for about 30 seconds and now it works. I don't know how to delete the thread.
A while back my HD7 (TATE) running Beanstalk OS (Marshmallow) started acting peculiar.
If unplugged from the charger, it will boot up just fine into the OS. However, after the screen times out, it will instantly shut off and begin to reboot. It will keep doing this unless I keep the screen on (using it) or force it off completely (shut down, or press and hold power for 5 sec). It seems that my Kindle Fire HD 7 doesn't like going into Sleep mode. I looked up and tried changing some of the default sleep state values via kernel editor, but nothing seems to help or make a difference.
I thought maybe it was the battery dying at first, so I tried to plug it in. I noticed that if I plug in the charger during the boot process, it just instantly dies and refuses to wake up unless I unplug it. However, once it is completely on and booted up, I can plug in the charger and it stays on and charges. That is, unless I let the screen time out... then it attempts to reboot but instant death because the charger is in during boot.
Oddly enough, I'm able to charge the Kindle when it is completely powered off by plugging in. Or I can leave the screen on by changing the power settings, and let it charge that way. Its become very difficult to use like this, however. Everytime I put it down, I have to either power it completely off or come back to a dead battery from all the bootloops.
In a nutshell, it seems that my KFHD7 Tate won't charge unless completely powered off or on- during boot it causes it to lock up until the cable is removed. It also won't sleep, as once the system times out the display and tries, it reboots.
