For me, the TP screen is completely off. No amount of button mashing will wake the TP up. USB connect to a computer doesnt show anything.
The last change I recall doing on the TP was to install an MDM (mobile device management agent) on it to centrally manage android. It worked, I could lock the device remotely, etc. The agent was collecting data (installed apps, gps/wifi coordinates, etc) every 30 min. Its possible it got into a loop and drained the battery. Thats about all I can think of.
I have not been able to get anything on screen (charge icon, questionmark, etc).
So I guess the only option left is to send it to HP.
The fix should be simple enough .. remove battery and charge it enough so that the TP's charging circuit will work. If HP doesnt want to touch it, I guess I will have to try this on my own.

You can find all instractions how to power/charge TP when there is a chargng problem - 99% that some of the solutions will worl for you
You shall contact HP when nothing works for you - they will replace the device in 2-3 day sending refurbished one to you (no questions asked). They don't have new devices so the refiurbished one could have different problems. I've got TP replaced 3 times before I received one in good conditions.

Vansun is right. I just got mine back from HP Warranty. Sent me a refurb or they repaired and wiped mine. Either way, was done under warranty WITH CM9 on it. Glad HP is fixing that. Just have to reload it now.

[zuzz]

I have called for a return. I told them it wouldnt power up/charge and that I tried the pwr+home button and a different charger. The support guy straight up said he would send a replacement. Told me it might take 10-15 business days, which seems pretty long. Its day two, I am still waiting for the return box to arrive (said it would take about 3 days). I'll see what happens I guess.

I have an unresponsive TP which was charging on Android and now does not work at all.  There were a few days of low battery icons which would reboot to Android.  I tried to go to change my OS but it show the low battery icon.  Now I have nothing.  No lights around the home button.  I have tried wall charge and USB charge but no response.  I have tried various home and power and up button pressing with no response.  Do I have any other options to revive this TP now besides sending it to HP under their one year warranty hoping they won't void it if they see CM9 on it?
Thanks for your help.

Did HP charge any of you when you returned your TP and it had CM7 or CM9 on it.  They were making a big deal about it when I was on with customer service when they determined my battery needed to be replaced.  thanks!

[smsmith1176]

Nope. I have had to have two replaced. You just get a fresh refurb.

I didn't read every single post in this thread, but did skim and didn't see any mention of this.

Buddy of mine claims the HP Touchstone will charge the device in the event you take the battery down too low.  Amazon has them for $33 at the time of this writing.  Seems a small price to pay to avoid having to replace the device with a wiped refurb via HP.

If anyone with a battery/charging issue is willing buy one and put this to the test, please post results.



Additional note:

Just talked to my buddy, and he said he actually had to do this himself (not just word of mouth).  Took a full 24 hours on the Touchstone before it recovered, but it did recover.

What have you done to try to get your TP to start charging again?    The wall charger is the best option to try getting a depleted battery to start charging again.  The TouchStone charges the TouchPad at a much lower rate than the wall charger.  Unless you have a defective battery, you can get it charged again.  Tell me what you have done so far, in detail and let's see what we can do.

I think you're missing a very important part of my post.  The "Buddy of mine" part.  I didn't do this myself, I can only tell you what he told me.  I also think you're missing the parts on the pages above in which people are saying flat out that they are not able to get their Touchpads to charge via standard chargers.

In any case:

He could not get his Touchpad to charge via normal methods after letting the battery drain.  He was told by someone (been a while, doesn't know who) that the Touchstone would get it working again.  He purchased a Touchstone.  He set the Touchpad in the Touchstone.  In approximately 24 hours, the Touchpad returned to normal function and no longer exhibited the symptons experienced when one drains the Touchpad battery too far.

Enjoy.

I can second hadji's observations. My own buddy tried all the tips about holding down buttons, leaving plugged in for hours/days/weeks, different cables, plugs, etc, and nothing would wake the thing up. I finally got a hold of it and put it on one of my touchstones. It booted up in about an hour and fully charged a couple hours after that. After charging once on my touchstone, his touchpad no longer dies for good. It charges fine by cable even after it shuts itself off due to a dead battery. My friend finally bought a touchstone a few weeks later anyway.

I have found the opposite to be true. Make sure you don't have a case on your touchpad which is causing the power transmission to be partially blocked. I had this happen with one of my touchpads when the case became warped and prevented the touchpad from keeping a solid wireless connection with the touchstone. Also make sure the AC adapter you have your touchstone connected to is the 2 amp one, not a 1 amp adapter.

Are you saying that the TouchStone charges at a higher rate than the wall charger?  Tell you what, download J.C. Sullins charge testing apk here:  http://goo.im/devs/j...cmtouchpad/apps and side load it.  Then put your TP on the wall charger and get the charging rate.  Then put it on the TouchStone and get the charging rate and let us know what you find.

Strangely enough, I too have observed this charging issue.  I've never had the ? mark, but have drained down to where it seemed not to accept a charge from the USB port.  Perhaps the key here is that the touchstone uses the inductive charging path. I'm guessing this by-passes any of the USB charge detect cuircuts.

Food for thought:

Using the jcsullins TPcharging utility, HP AC stock charger has max charge limit = 2000 mA.  The Touchstone max charge limit = 1400 mA, a slower rate of charge.
If you connect both...  it displays the max limit as 1400 mA.  I had hoped I would achieve a faster rate of charge, my independent test and this utility indicate otherwise.

To my point:  it may be posible the USB charge detect curcuits cannot enable charge path, but that in some cases, the Touchstone induction charge circuit can still operate and get a minimal charge to a point of operation?

Id love to have a schematic diagram.

I had this problem before. I just plugged into the charger for an hour or so then i pressed home and power button then it all worked fine! All that happened when i was still using webOS

[JWSmythe]

Guys, I have some advice for you, before you consider contacting HP, or (god forbid) changing the battery yourself...

We got 3 touchpads on firesale..  I set up one for my girlfriend, one for myself, and the third is still in the box.  On ours, I put 7.1.0-RC1.  Dangerous, buggy, sure..  But it worked.

My girlfriend leaves hers charging, so it's always ok.

Mine...  Well, I kinda put it to sleep and left it on a shelf for about 8 months. The battery went completely dead.   I knocked the dust off it, and tried all the button push combinations.  Nothing.   I plugged it into a wall charger for an hour.  Nothing.   I went reading around about how to fix it, and found plenty of people saying to RMA it to HP for a replacement.   Instead, I left it plugged into a wall charger overnight.  Nothing.  I started considering my options.  RMA, and/or use the spare which probably also has a very dead battery by now.

Being the highly motivated procrastinator, i left it plugged in, and stuck it by my monitor.

Probably 24 hours after starting this exercise, the home button light started doing the wig-wag thing (the button light alternates left to right).   That's an improvement.  

Sometime that night, it booted by itself.  Whohoo.    The following day, it was fully charged.   Feeling all succesful and stuff, I did what any procrastinator would do.  I stuck it back by the monitor, and planned to mess with it later.

At some point, I pulled the power cord, and stuck it in my phone, and forgot to plug it back in again.

So now, a month or so later, I grabbed it, planning to test upgrading it to the current nightly..   Needless to say, it's dead again.

This time, it started the wig-wag after about 2 hours, and booted about a half hour after that.

In the time I've written this, it's gone from 4% charge to 13% charge. I'll wait for it to get to 100% and then try upgrading it..  Or I'll procrastinate and do it next month.   Oddly enough, looking at the battery, it says "14% : CHARGING(AC)[ 32F ]"  I guess the temp sensor is either funny, or didn't work very well in RC1.

So, simply enough, plug it in.   Plan on leaving it charging for a week.  It should come up much sooner than that, so you'll be happy when it's alive in a day or two.   It'll take longer, if it's deader.  Don't panic.   If it didn't do anything, you may want to make sure the cable and adapter are ok.  If you're like me, we have a nice collection of about a couple dozen microUSB chargers now.   Try another one.

FWIW,  you are living dangerously letting your TP discharge like that.  I don't know how much you read other forums, but the TP has developed a habit of not charging back up after being allowed to discharge to zero.  You've been lucky so far.  If you value having your TP around when you want to use it, I would make sure you keep it charged up, do not let it go below 20% without charging it back up and when you don't plan to use it, turn it off.  If you don't use it for long periods of time, plug it in to the charger around every three months and wait til it's charged back up to 100%.

And to make matters worse, HP had started refusing to fix TP's they find Android installed on.

Pretty soon it won't matter as the warranty on almost all TPs will soon expire.

Ya, I know there's a point where the battery will be dead-dead.   I have my spare, new in the box, but I can't imagine it's doing much better.  They'll all die eventually, box or not.

It's hard to rationalize keeping every device with a battery plugged in all the time.   At some point, this will be obsolete, and I'll go for a new toy anyways.   It can then join countless generations of cell phones, laptops, and even my Compaq iPaq H5150..   The iPaq was the first device I could go network monitoring with, without needing to carry a laptop around..  Of course, it did have a 10 pound battery pack sleeve and full size PCMCIA wifi card, so it wasn't exactly covert.

The battery replacement in the touchpad is doable.  It just takes a steady hand, and a bit of luck and skill.   That's all HP is doing anyways, when they do fix them.   It's still better to advise "plug it in for a week", than "send it back to HP".   Since most people are saying it should come back to life within an hour or two, that means they're needlessly sending their touchpads in, when they could have just let it charge longer.

FWIW, I've been carrying mine to work for the last two days, and doing all kinds of stuff with it..  Even with it tethered to my phone all day, and monitoring the OBDII on my car, it's only went down to about 50% in 12 hours.   It's doing better than my phone with wifi and GPS turned off.
