If you have an Hp Touchpad then you have probably went to a charging problem! When the red battery symbol with a lighting in the middle shows up for 1 sec and then goes to a charger symbol! I have experienced this a couple times my self! Read below on the different ways you can fix it!
Method 1:
Charger port (Not cable) has 2 parts! Unscrew them and reattach them!
Method 2:
Hold the Power Button (On Top Of Tablet) and the home button for 15 seconds!
Method 3:
Try using a different Micro-USB cord!
Method 4:
Connect to a different charger...(Make Sure It Is A USB 2.0)!
Method 5:
Try RE-FLASHING the Rom! Try using ClockWorkMod Recovery first. If that does not work then try using the ACMEInstaller!
Method 6:
Let the TouchPad sit for about a Week! So the battery can 100% drain! Usually when you run out of battery there is still about 5% left! Then try and charge it!
The Hp TouchPad only charges on a 2.0 charger! It requires that for more charging power! It does not matter what kind of Micro-USB cord you have! When my charger went out (UNIT) I hooked it up in my car (Has USB Port) and it charged great!!!
Leave a comment below if you are still having problems!

We have two modded touchpads with similar charging issues..the stock charger wont work on either and we have to use a touchstone to charge.. touchstone charges extemely slow 3 hours maybe gives it 30% charge at best.. plus the battery runs down very fast..
I have tried the double reset mentioned to no avail.. i am very wary about opening this up to tighten some screws as I dont want to damage anything. I have never opened these up before. I think my computer is not USB 2.0 as I tried charging once and nothing happened.

Any thoughts. This is driving me crazy
Not sure about the screws, but if you take the plug end of the charger and rotate it back and forth it re-establishes connections to the body. I don't recall it unscrewing, just rotating maybe 90 degrees or so - just twist it one way and back the other until it stops. Unless you're really ham-handed you won't break it.
I don't know if this is some sort of reset or just opening and closing connections, but it seems to work in some instances.
Since the Touchstone is inductive there is a "sweet spot" where it charges best. This is especially true if you have a case. I have a leather case on my 32GB TP and I have to be very precise about how I place my TP on the Touchstone to make sure it charges. With the TP turned on, try placing it in the Touchstone and making sure it's centered. You might even open up the Settings menu for the battery and see if moving it around just slightly changes the charging rate - I'll bet it does. If you have a case, take it off and see how quickly it charges that way.
USB charging by plugging it into a USB 2.0 port is limited to 500 milliamps (half an amp.) Charging through the wall charger is 2.0 amps maximum. If you attempt to charge it through USB and use it at the same time you'll probably have a net loss, depending on what you are running at the time.

With your Touchpad plugged in to the wall charger and charging in CM9, open the terminal emulator app and type su and tap enter. If it asks for super user permissions, allow it. Now type "cat /sys/power/charger/currentlimit" (without the quotes) and tap enter. Note: there is a space between cat and /sys. What result do you get?
If it is charging correctly, you should get a report of 2000mA. What does yours say?
Ok.. so i tried twisting the plug.. it did twist and clicked in different position.. but it still doesnt charge the touchpad at all with the original charger..
I entered your info with the touchpad on the touchstone.. the total came to 1400.. not 2000.. and I always center the pad and take it out of case to charge..
We do not abuse are pads and dont get heavy use either..but its hard when they take forever to charge even 1/2 way..
Rob
Well would i would suggest now is buy another charger! If the touchstone at least charges it then you know that the TouchPad is not the problem! Also some cars have 2.0 USB ports that you could try! And pretty much any 2.0 USB will work with the TouchPad!

The charger that came with your Touchstone is the same as your stock charger. Have you tried using it to charge using your USB cable?
So... i went to plug my tpad to my ps3 40 gb with 2.0 usb.. NOTHING.. it does s-l-o-w-l-y charge with touchstone, but I cant plug a touchstone charger into my USB port cuz its not built that way. Whats weird is that both connections should go bad about the same time?
When you have a touchstone charger you dont use the side port on the pad (for those who didnt know). I dont know how to fix the connector and dont really want to take both in and pay for two fixes.
Most data USB ports (i.e. the one on your PS3 and the ones on your computer) will only output 500 mA. While I can successfully charge my Touchpad like that if I leave it overnight, it's outrageously slow and if you've got anything draining your TP at all, it might overwhelm the charger.
If you plug your USB port into the computer, can you transfer data?

I fear there may have been some confusion when I suggested using the charger from the Touchstone. Just to be sure, the charger that comes with the Touchstone is exactly the same as the wall charger for the Touchpad.
My suggestion was that you unplug the charger from the Touchstone and use it to attempt to charget the Touchpad.
This would give you an idea as to whether the issue is a cable or a charger.
Ok.. it appears that both my desktop and laptop do not have usb 2.0.. i tried charging but nothing appears when i plug in usb..now. the touchstone IS different.. one end has standard usb with plugs into wall outlet adapter.. the other end is concealed inside the touchstone holder which you place the pad into.. there is no option to unplug this end the way it is made. But I can try to use just the end piece of touchstone charger with my other reg charger.. i do have two regulation chargers which were both not charging at all or correctly.
I live in the US, Orange County Ca, and really, really, do appreciate all your ideas to help me out. I love my modded touchpad like you good folks do as well. I can try plugging directly into wall, which might be problem here.. Let you guys know.. thanks again.
Right. So take the wall outlet adapter, and unplug the Touchstone.
Now take the Micro USB plug that came with the Touchpad, plug it into the wall outlet adapter, and plug it into your Touchpad. See if that starts charging it.
Results are in.. tried charging directly into wall.. using touchstone wall plug with reg usb cord.. nothing.. using touchstone charger normally.. charges on both web OS and mod.. when i tried charging with different cords plug into the side.. no results at alll..
also with touchstone wall plug combined with usb into side.. no charge..
Ok well I do have another way that may fix your problem!
Try and RE-FLASH the Rom you are using! Go through all the steps on how to flash a Rom! I would try using the ClockWorkMod Recovery first but if it still does not work then try to use the ACMEInstaller!
Sometimes there are errors with the Rom that could be messing up the charging!
Hi.. i had a friend do the modding for me.. and yes, both were done at the same time.. also, the usb charging port did not work on both web os and android.. it did work better this weekend by plugging touchstone directly into wall.
One other issue.. is that the battery drains incredibly fast with the mod..probably cant go 4 hrs or more on full charge.. when i had web OS, it was at least 10-12 hrs of use.. i honestly dont use web os anymore so i cant say about the current use.. i will have my friend flash the rom to see if that works.. his touchpad seems to be working fine.
Again.. thanks a million for the help.. at least i can get faster charging now directly into wall..

I thought I had bricked my CM9 Touchpad but it revived after 15 hours charging with wall charger.
It died when I tried to reboot with USB cable connected to my PC.
Curiously, my PC would recognize it as a Palm device even though it appeared dead. PC said I needed drivers, which I didn't try to install since I had no idea what would happen.
Well even though some computers show that it is charging it may not be charging! I usually get about 10 hours on one charge with the CM7 alpha 3 or CM9 Nightlies! So I would suggest trying to flash one of those! Also you could try MIUI! I heard from a lot of people that the MIUI rom was a good one!
I dont know if this will help but I have a tp on the regular cm9 alpha 2. I have drained the battery before and charged it back up without a problem but last night it died and I left it on the charger, the battery charging picture showed up so I thought it was good. The next day I checked it and it was dead. So i tried it again and checked it a few minutes later. It booted to cm9 but the charge stayed at 0%. I left it for a few hours and it was dead again when checked it. So this time i waited so I can boot it to webos. On webos the charging went up to 2% in about one minute and is steadily charging. So i think it does have something to do with cm9. On a side note the oem usb cable is crap, It only works on certain positions.

If you had updated to a nightly build, you wouldn't have had this issue. This issue was fixed, along with a bunch of other issues.
You should update your TP to a nightly build and you'll enjoy a (mostly) fixed microphone, wifi, and no reboots when it sleeps. We may have a fixed camera soon too.
This guy is 100% correct! The CM9 Nightly builds update small little bugs! You can also try and flash the CM9 Alpha 3! No camera yet But still great to have ICS on this device!
I would suggest that you run CM7 until they have a more (Stable) version of ICS! Even though like he said they are fixing the bugs on the Nightlies!

CM7? CM9A3? No way.
CM9 will do circles around CM7 and it has progressed a LOT further than CM7.
It sleeps without rebooting.
Wifi is fixed.
You can play music with the screen off.
Microphone works and camera is getting there.
Sdcard fix is included. (Check integrity of sdcard on each boot.)
What advantage does CM7 have?
CM9 is close to release candidate status. Maybe you want to check the CM7 changelog.

The only reason I suggested CM7 was because of the camera working! I use the camera a lot! And I do agree that ICS is WAYYYY better than Gingerbread! But I decided to just use CM7 until CM9 comes out with a camera fix!
So first I was getting the HP logo and according to my research it said you had to webos doctor. I got the file and even figured you had to get the initial file, updated my java for that and blah blah blah.
Then, to make my life harder, the damn thing stopped taking a charge. I did ALL of the recommended fix. Playing piano beats with the buttons to a certain tune, twisting the charger block that came with it, tried different usb 2.0 cords, different outlets, etc etc etc
I don't get any feedback such icons or lighting up. Nothing.

So what rom are you running? Cm7? Cm9? Something else?
What version?
A nightly build of cm9, (at least July 7 preferred), would have everything working except the camera (which might not ever be fixed). This includes any charging fixes.

Yea this is kinda outdated! But i left it up for people to use if they are running a earlier ROM such as CM7 or MIUI!
Dead touchpad for me too running CM9 nightly 19th September. TP normally drained prior to charging (used by my kids for android apps & they don't stop until the screen goes black!) it now won't reboot - left on usb charge on laptop for a couple of hours, no joy yet - will leave on overnight & see in the morning.
I've flashed about 20 of the nightlies & this is the 1st time i've had this issue - posting this to ensure people still aware there can be issues with charging after June nightlies (even if it is a bad flash)

If there's a chance there's a charge left, then you want to hold the power + home buttons pressed for at least 30 seconds to make sure there's isn't an app preventing it from shutting down, then throw the charger on it.
Otherwise, if it's completely dead and you can't resolve it by charging with the stock charger and stock cable or USB and you've checked the charger on a different device and you know it works, then the only recourse may be to open it up and charge the battery directly (best left to an expert).
The stock charge is rated at 2 amps so you really need to be using a charger rated at 2 amps.

Thank the lord for internet forums! After leaving connected to usb port overnight - eagerly woke to find...nothing. Left charging in usb 2.0 port all day whilst at work, eagerly checked when came back home...nothing. Symptoms at this point were the same:
1. Holding down any combination of button did not work - most common sight was the battery with volt symbol & red line, followed by plug symbol.
2. Reconnecting to laptop netted the battery/volt/red line symbol, followed by use the correct charger screen.
3. Connecting to the mains charger - resulted in nothing.
Then the miracle occurred, the sequence of events being (in the space of 2 hours) although most steps are superfluous - i've kept them in to show the method (however mad it seems)
1. Disconnected from usb port to plug into mains - no change
2. All combinations of button presses - no change
3. Reconnect back to usb port - no change
4. Disconnect & reconnect to mains charger - continuous battery/volt/red line symbol
5. Left on this screen (because it was something i hadn't seen)
6. After 20 -30 mins in booted to moboot (which i was really lucky to catch with 2 seconds to go until ICS boot) when i put into WebOS and now charging.
Upshot is that i think the trickle charge via usb for circa 24 hours followed by quick top up at mains got it enough charge to reboot.
Hope this rambling helps anyone else suffering the pain!

Same issue here with charging. Running CM9 latest nightly. (0923 I think). TP charges w/o issues in WebOS, but flakes out in CM. Indicator shows battery charging, but level still drops until it goes into sleep-of-death.
Always have to finesse it out of SOD and charge it in WebOS.
Is there still no fix for this? Otherwise CM9 is pretty solid IMO.

I'd create a backup in recovery and Titanium Backup, then wipe data, both caches and flash a good version, like the nightly for July 7th and gApps. (Sounds like some of the recent nightly builds have wifi problems.)
See if that has issues. If it's no better, then restore your backup in recovery and nothing lost.
I found that my TP was better after a wipe. A year of upgrades (apps and rom) had apparently caused some little issues here and there that a fresh install fixed.
If the new build is better, open TIBU, and batch restore and choose "restore missing apps with data". Do not restore any green or red items since that can cause issues.
I see an 0930 nightly is out, I'm going to try that first. If my senses are working, I seem to think the charging issue had gone away until the 0923 nightly. I could be imagining it, but I'm going to try the 0930 then go back to the 0909 which I used without issue.
If no-go on any of those I'l wipe and reflash. This TP is almost useful now, but the charging is an issue.
...ok, 0930 nightly is installed, let's see how it goes.

yes. i do a backup. and yes i agree that after multiple installs and tweaks, etc sometimes its good to get rid of the clutter.
I'm pretty certain the charge was OK up to nightly 0909. I can also see right now the charge is looking OK. I'll know more after a couple of days.
I'm back. Same charge issue with 0930 nightly. I'm having trouble finding the problem here... not sure what to try next, or if I missed some secret fix out there for this issue.

From a feature standpoint, there's no big benefit to any build after 7-7 nightly, but there may be differences in battery use (gain or loss) when sleeping or degradation in wifi usability. If you have a working backup, I'd stick with it, o/w if you hope to report a bug, Rootzwiki would be a better forum for that. As you can see, it's nearly a ghost town here.
Hp TouchPad CM9 and CM7 Charging Problem *FIX*
But still great to have ICS on this device!
Nothing, nada, zip
