Great. You have two touchpads and can open it by yourself.
For device one.
1. must ust HP orginal 5.3V 2A charger head and orginal cable. don't use 5V charger. Battery seem OK. Can check it with metre Volt...(Just no power in it). Can charger it over 12hours with 5.3V.
For device two
1. running Webos and Andriod. Battery is locked . Because lost power too much (Maybe 0.00V if check it)
2. mainboard is OK. don't do wrong step to it. don't charge battery directly jump up the board by yourself. It hurt the battery....( need a special software to fix it)
3.If device one can work. Put the device two battery into device one and charge it.(50% can work.cause the board is locked.the best way is put into webos touchpad to charge it).

Good luck !!

funny...what cable are you using ? Should have small silver round on two heads of cable (HP cable).
For device one. When it was charging home light show left-right-left. Also show please connect original charger or original cable on the top right side of screen ? Can you see screen turn on? Maybe power board does not sit right place....
For device two. Battery is dead/locked and mainboard do not connect it. No working for a long time....

Try to use TPdebtick 004 to fix it. But it doesn't have 100% sure. If can not finish it and can not reach "All Done". Will kill the mainboard.

If device can turn on and see home screen. The battery is OK. Forget the warning and charging battery to full.(Hold the home +Power over 20 seconds).
Take this full battery into device two. Will see the battery symbol with question mark (90% chance). If see blank on the screen that's hardware problem. Need to inspect it step by step....

I think that it is diffculte to fix dead TP battery by yourself. It need special software and speical tool. connecting to AC and PC to fix it...

I guessed right. There is power bug for touchpad that running webOS /CM7.9 together. And lost the power completely.
1.disconnect the battery over one minutes.
2. Connect the battery again. Don't turn on the device. And hold power +vol up right away.
3. Can see the Big USB on the screen.
4. Running 3.0.5 doctor on the PC.
5. Connect touchpad to PC. And click next...
6. Waiting for doctor finished. Don't disconnect USB cable in flashing. It will burn the mainboard.

Good Luck

Which battery is using? Need the power battery. ....
Open the back cover again. Hold the power +vol up first. And push the hard set one time. Where is in the end of mainboard (narrow side). Golden round beside the SIM card set.
Try again.....

Are you sure hold power+ vol up ?? I feel that you hold power+Vol down and turned on device showing battery symbol. If the power on your left. Vol up is same on left. Vol down is on the right.
Disconnect the battery . Repeat it again...
If can not enter recovery (See big USB). That's a big problem. Really.....

. Can not help you now. It is headache that can not enter recovery for touchpad. Can not connect PC to fix it.
Try to use TPDebrick 004 from Superman JC. It is your last chance.(I think that last owner of touchpad had done something into it. Not sure).....

Check permissions? Check that you have the loader library that corresponds to the one needed in the binary?
