I have the same issue too... Only difference is I haven't used my TP in over 7 months so the battery drained on it's own and today when I plugged my TP into the wall charger nothing happened I just saw a black screen... Although I did notice that the home button has a white strip running from the left to right and vice versa... Do any of you know if this is normal and if it will just need time to recharge??? It's been on the charger for the last 4 hours and I still have not seen the logo come on nor have I been able to turn it on... PLEASE HELP!!!!

So, this is what worked:
1. USB cord plugged in to charger connect to power
2. hold volume up button only -- don't let go and plug USB cord into touchpad

After charging for a few minutes it automatically booted! The charge indicator showed only 3% on the battery. Right now it's still functional and charging, up to 15%. I think it's going to be OK!
lt worked! Thanks so much. I had tried everything.

Hi, I tried pretty much all combinations of chargers and buttons. Had no luck until I plugged it into an old USB hub I had lying around. Plugged into the power port and within a few seconds I had a left & right flashing light on the menu button. That soon went out (might have been the fact that the PC went into sleep). Anyway I then plugged it into the HP plug (btw - check the micro usb cable as mine had become faulty). Waited about 10 minutes then pressed the power & menu button and the TP sparked into life with the battery charging graphic. My 3 year old is now a happy child again...

Hope this helps someone. The USB hub I have is an old Targus one.

Boy that was a long way to say I put some charge on the battery of my dead touchpad and brought it back to life. Anyway even if you don't attempt this I hope the information is useful for someone who wonders why their TP died and what HP might have done to fix it. Enjoy!
Worked for me - thanks so much! For the record I used two bent staples to go in the holes, and a universal battery charger which has polarity detection - some trepidation but it seems to have done the job. Mine looks like the one in the picture below, I've also used it in the past to kick-start an OQO battery in a similar state...

I took some of the advice I found here and let it sit on the USB cable on the computer for several hours, during which I saw at one point the alternating flashing on the home button light. When i disconnected it from the computer, it seemed dead still, but NOW when I tried the on button/home button combo, it flashed the low battery image in the middle of the screen. I connected it forthwith to the HP charger, upon which it resumed the alternating flashing home button light. A few minutes later, it booted up CM9 and said "Charging - 17%"
w00t!
Same thing dude I was stressed out tried everything it is now at 20% and charging.
Thanks

One red one black or put a jumper between the two reds and one between the two blacks charge from these connectors. I guess what I don't understand is why I don't see any voltage when I check the reds/blacks.
The Touchpad battery contains two cells. Each of the red and black wires connect to one of the cells. When charging ensure both red are connected to positive etc.

Had one of my Touchpads on trickle charge for two days - I simply receive the battery icon with a question mark. Anyone know what this means? I suspect one of the cells is dead.

Thinking about buying one of these:
Genuine HP 9.7in Touchpad tablet li-polymer battery 6000 mAh 3.7v HSTNH-I29C | eBay

Has anyone had experience of these batteries? Are they OEM quality?

Generally the big question mark means it needs more charge. But not sure it could have other meanings.

Bought a battery for my Touchpad from another seller, so I can't say if this would be identical to the one I got..

But mine was identical to the original and worked fine...

From the picture, that looks identical.

It helped get my Touchpad back to life (but still needed to do the Ubuntu Fix for the charging unit), and once I got my Touchpad working, I did put the original battery back in (and it charged fine) and have kept the new one as my backup.. as I have 3 Touchpads, I'll need to swap batteries at some point.

I've been trying for months, (it might be up to a year now) to revive my TP. I tried leaving it on a charger, plugging, unplugging, button presses of every conceivable combination. In all this time the only sign of life was the home button blink exactly once.

I jotted down your instructions, along with another from another thread. I had very little hope this would work. I tired your's first because it was simpler. It took several attempts, but I got the home button blinking left-right! It's charging right now and I think I might be able to revive it! From what I read here, it should be charging when the home button is blinking in this fashion.

I thought I'd killed the golden goose. The first time I got it blinking, I waited a few minutes, then decided to see if it work on the Touchstone. It didn't work (I didn't try too hard) and it took a few tries to get going again on the USB charger. Whew! If you can't get it to work the first time, keep trying. I don't know if it makes a difference, but the two time I got it to work, I released the Vol+ button about one second after plugging the charger into the TP. It did not work if I released the button quicker or slower. To be fair, it didn't work several times releasing it after one second.

The other instructions I didn't try: plug the charger into the wall without a cable. Then connect the TP to a powered USB port on a computer with the HP cable and let it sit a short while. Then move the USB end of the cable from the computer to the plugged-in wall charger as quickly as possible.

I'll report back with an update....

Thanks so much!

Update: At 10:35, after about 6 hrs of charging with a left-right blinking home button, the big battery icon showed. Some hours later, I noticed the home button was blinking two pulses. I hit the power button and opened to the lock screen! Yeah! Back in business! Thanks so much!

I purchased a new battery, installed it and still have the white question mark.

Do I have a bricked Touchpad?

How could I restore it?

So, I have a thunder AC6 charger (Thunder AC6 Smart LiPo Balance Charger/Discharger w/ AC Adapter for 1-6 Lipo/ 1-15 Nimh + USB to PC Software) and when I tried to charge the battery following the procedure above. The charger start and after 30 seconds got a message that the battery is fully charge. Any idea? Also. Can I use the deans connector (see URL Link above) to connect the battery directly to the charger?

Plug the bugger in on your wimpy little USB cell phone charger and let it trickle charge at that low, 1000mAmp rate for a couple of hours and see what happens. I revived mine doing this, after the TP wall charger did nothing for 14 hours. It appears that if the voltage drops too low, the only way to charge it is using the standard USB voltage and not the higher voltage normally fed out by the TP wall plug or Touchstone. Definitely try this before you go through all the trouble of pulling the thing apart.
THANK YOU THANK YOU THANK YOU!
After two weeks of a dead HP Tablet and trying every trick my searches suggested, I found this one above...using the charger for my cell phone and charging the Touchpad at a low voltage. I plugged it in yesterday to the wall outlet and instead of coming back to a black screen this morning and no flickering white light on the front button, I had BOTH! I also had a message that the charge was too low. It had charged to about half the battery capacity. I unplugged and then plugged in the HP charger that came with the Touchpad and, to my great happiness, I once again have a fully charged, working Touchpad.

1 Hold power button and push home button 10 times. This put the Touchpad into a low power mode.
2 Now Hold the volume up and the power buttons until the battery icon and plug symbol show up (10 seconds) plug your touchpad in with the wall charger.

Charge the device until it powers up. (I am at this point right now and will update after it powers on. If it powers on.

UPDATE*

It worked. After 3 hours it booted up and is fine now. WOW

HP Touchpad dual boot webOS and CyanogenMod9 was left unplugged and battery died while running the Android OS. It would not power on or charge. The above steps worked to fix it.
I did nearly everything mentoined in this thread above that quoted post, but nothing happend.

Then i tryied this "low power mode" manual and it did not show the "the battery icon and plug symbol " but after putting it into charger now my home button flashes left-right continously first life sign since days.
Btw. don't know what kicked the battery while sitting on the Touchstone.

Btw. before, all my different the wallchargers (500mA-1A-2A) only showed a charging rate of 0,7W to 0,9W (measured with wallplug power meter) Even after days nothing happend.

Now in this low power mode and with original TP Wall charger it shows again 9W and now (after 3mins) the empty battery symbol just apeared on screen (flashing home button gone) and it shows a charging of 10.1W

Will update...
Booted up now to webos and charging @32% (TP charging also works - so don't know what happend there) - will see after some charging cycles if the battery took a hit.


Thx everyone...

Well i would provide if i could:
Yes I have LunaCE
Yes I have ACL 0.6
Yes I have CM9 (with automatic shutdown at 25% battery)

But i usually do not leave CM running while charging or leaving it for more than a night - then i do reboot to webos.
I usually always deactivate WIFI and put screen brigness to minimum while not using.

Fishing in muddy waters:
As that weekend we had guests i did not use it the whole weekend and it could be that i rebooted and put it directly on the touchstone without waiting that it booted up webos. I had a window open so it could have gotten a bid colder, but it's not very cold atm in central europe.
I don't know...

To me and a friend happens without having ACL, my friend haven't use Android or LunaCE on TouchPad.
So I think we can exclude these factors.
I'm pretty sure it's a hardware thing

Is this what the A6 firmware flash is said to resolve?
