Hello guys,
I'm new here at the HP Touchpad Section and XDA-Dev Forums.
I am running CM7 on our HP Touchpad and my little brother has been fiddling with it(downloading many apps from the playstore using my personal account, thus forcing me to create a new google account/other shiz).
Then one time, the screen kept turning on and off without us even touching it. Our guess was it was dust on the screen which is being register as touch.
After a week or so that that was happening, the touchpad ran out of battery and was not charged right away.
The result, it won't charge anymore.
Is there anyway to open the device and shock the battery? It may be a dead battery just like what happened to my sister's iPhone.
I've also been reading some charging issues with CM7 and CM9 and tried some of their troubleshooting methods but non worked.
If I just get a little juice to boot it, I would reboot back to webOS as fast as I can and uninstall CM7.
Thanks in advance,
Raphael

Try leaving it on the stock charger for several hours, maybe days. If you have a touchstone, try that.
If you get it to charge (make sure it's fully charged), uninstall CM7 using acmeuninstaller, then boot into webos. If you have preware installed fine, if not install it and download 'remove android' (or something like that). Run it, then install either CM9 or cm10, using acmeinstaller3. There are several good how-to's which you can search for here or at webos nation forum.
When you have it installed, go to settings > storage and click on the 3 little squares on the upper right hand side, and click on usb computer connection. Then make sure the MTP box is checked.
Hope this helps. Good luck.

Thans for the reply chicle_11! Will try that on the weekends since I am very busy with school works. And thanks for the suggestion of installing CM9/CM10 but I will just stick to webOS and get an authentic Android Tablet(I'm choosing between Google Nexus 10 or Samsung Note 10.1).
I use webos at least 50% of the time. It's a shame that there aren't more apps compared to android. You don't have anything to lose by installing android. You'll have an excellent and unique dual boot tablet. CM10 is very stable now, I use it as my daily driver, I highly recommend it.

I still might reconsider flashing CM9/CM10 when I sort out the charging problems since I am just starting to save money for the Note 10.1/Nexus10.
Can you recommend a good CM10-based ROM for the HPTP or just the stock CM10 Jcsullins?
I use/recommend jcsullins' cm10.
Make sure MTP is checked (follow my first post) and that should take care of the charging problems.
Also, try to not let the battery run out of power. It could possibly brick the tablet.
It seems that I have somewhat sorted out the charging problems. I read an article last night that Samsung Chargers also work for the HPTP.
The process is fairly simple. Use the Samsung Charger first to charge a phone. After 2 hours or so, use that charger for the HPTP to charge the touchpad from a used/electrified wire. During the other process, use the HPTP Charger for the phone to power the cord up. After 10mins or so, switch both chargers. So the HPTP should be using the one that came with it by this time.
It worked for a while then the "Please use the charging cable that came blah blah blah to fully charge..." message came. I've read another article that the touchpad should be a little elevated or at least level with the cord so the cord will not fall down that is causing the message to pop up.
I've used both methods and the 2nd method is working like a charm. It shows a battery sign with a lightning bolt and the charging warning/message does not pop up. Will leave it overnight to see if it charges.
Then after, I might reinstall CM9(I've been from CM9 but downgraded to CM7 because of camera issues w/c my lil bro does not like).
So I left it overnight and it charged when I used the 2nd Method. Happy Days!

Sorry, That was late night here in the PHL and was a bit sleepy when I was posting that.
Also have dead touchpad
I haven't been able to see any life from my touchpad after the battery completely drained. Its been 2 days since I haven't been able to use it.
I've tried charging it via the cable and adapter that came with it for a couple of hours, left my TP on the touchstone all afternoon to morning and no life either, the touchpad however is a bit warm at the back. Does that indicate its charging?
my TP is sitting on the touchstone now but I've replaced the AC adapter and currently using my HTC Sensation plug, I am running out of ideas and I'm going to presume its completely dead.........
I've tried connecting it to the pc but nothing happens, Can someone help me out, I've also tried the button combinations "Home, Home+Power and Home+Power+VolumeUp"
I tried both of the methods mentioned a couple of posts ago with no success.
I have also left it on the regular AC charger for 48+ hours and a Samsung cell phone charger for another 48+ hours and nothing.
It is sitting on the Touchstone now for 36+ hours and nothing yet.
I sent HP an email and here is what they said to try:
"We gather from your mail that your Touchpad is unresponsive and will not turn on. To be able to help you with this issue please take note of the following troubleshooting steps:
First of all leave the device on charge with charger for 48 hours after do the following:
Press and hold the power button + Center for 15 seconds. The device may take a few minutes to restart.
Please do the above with the device connected to the charger. (not charging dock nor PC).
Press and hold the power button + volume Up + Center and continue holding for 5 seconds after the Full Erase screen appears.
Also please try the above steps with another USB cable, also please try to connect the USB to the computer with the touchpad, if the computer doesn't recognize the device, the USB cable is faulty.
Please try your charger on another device to see if this charges the device. As the issue could be that the AC adaptor that is not working.
Have you tried another charger with the Touchpad? In order to verify where is the problem. Regarding to your problem ,do you know if the problem is with the charger itself or with the USB cable? Have you tried the complete charger with another Device, phone?
If the steps given do not help you with this issue, please send us a Proof of Purchase (scan of store`s receipt attached to your response) to validate your warranty or the order creation date of your device and your address.
If you need further assistance, please reply to this message and we will be happy to assist you further.
For information on keeping your webOS and Palm products up and running, please visit our website at: http://www.hpwebOS.com

None of that worked either. I just get the "Palm device" balloon on Windows XP when I hold the Power+Volume Up + Center button. It looks for drivers but never finds them.
Also try holding Home + Power button for 30 seconds instead of 15...This has been known to force some life back for some

Nothing after trying that and leaving it on the Touchstone for 48+ hours. Time to leave it plugged up to the computer for 48+ hours and see what happens.
Nothing after 48+ with the factory USB cable connected to a desktop computer.
It would be nice to see a solution that works every time instead of a bunch of guesses.

First my observations on three 32 GB TP's:
My discharge rate on WebOS in Airplane mode was arround -613 to -850mA. Screen on, (brightness affects this).
3. My discharge rate on CM10 in Airplane mode is about -520mA!!
4. A PC's USB port puts out 500mA's!!!
5. On the touchstone, (doesn't seem to matter if WiFi is on or off), with screen on 1/3 brightness + Battery Monito Widget = +853 to 945mA
6. On HP charger & cable, same as above = +1,377mA
What suprised me was the greater drain in WebOS.
You PC's USB port may be causing further discharge to the 2% TP's auto shut-off!
Actually none of these goofy button pressing and charging methods was right. A6 was faulty. It is fixed now.
My TouchPad is dead

My TouchPad discharged overnight and now just has a black screen. None of the button pressing or charging suggestions described in these forums has worked for me. I was just running webOS 3.0.5. No version of Android was on the TouchPad.
Please tell me the trick you used to revive your dead TouchPad. Was it just a problem with your Andriod OS?
Much thanks.

http://rootzwiki.com/topic/36658-tpdebrick-v01/page__st__300
This is the second time I've had my TP hit 0% battery while in CM9 (relatively recent nightly build) and auto power off and not respond to charging or boot attemps. I can't say for sure which nightly but probably from 6-12 months ago. It's been realtively stable with no problems i could discern. Anyways. Recently, the first time it lost power down to 0% I searched for solutions to the problem. I found the solution, based on the symptoms, to be TPdebrick. I followed those directions to the letter and within a day or two my TP was back up and running after fully charging. I don't recall precisely what occured after completing TPdebrick and the TP booting up again as I had gone to sleep, then to work, had a bunch of other stuff to do after work, then sleep again before I went to check on the TP to use it.
I'm concerned that it isn't actually charging it this time, even though TPdebrick completed successfully. I have tested the USB cable and charger and they are both fuctioning and able to charge my smartphone. The wierd thing is it did charge for a short period of time right after using TPdebrick (according to the output the battery voltage was at 30xxxxx [I don't remember the numbers where I substituted xxxxx]). But not enough for it to reach minimum charge to boot. When after 24 hours on the charger it was still no responsive I thought I'd run TPdebrick again to try and jump start it again so to speak. This time around from the log is the following:
Starting battery authentication...
Battery authentication successful.
battery_info.percentage = 0, battery_info.voltage = 3225680, battery_info.current = 937, battery_info.temperature = 20
This appears to show that it did charge up a little bit from that brief time it began to charge. And that it was recieving a small amount of charge from the PC. Typically when it is charging the cylinder part that plugs into the outlet gets warm. But it isn't getting warm as expected when the TP is connnected. I've also twisted the plug part off and back on several times along with using my smartphone to test that it was able to charge each time. So I'm stuck not knowing if the TP is actually charging because I have no visual or physical indicators that I can determine if it is or not. Any help would be appreciated.
Install the attached file to your touchpad and run it with your charger plugged in. It will tell you if your battery is charging and what current it is receiving.
Just unzip the attachment and install the .apk
Peace

Since I can't boot the TP how do I install that and use it to get the info? Unless there is a misunderstanding. TPdebrick fixes it so it can charge so it will boot but I don't know if it is for sure charging so that it will eventually boot or if I need to use TPdebrick again. Assuming that despite the appearance of TPdebrick having completed successfully running it somehow didn't fix something. I would assume that at this point my options are few. If software means of getting it to boot again don't work I would have to disassemble the TP to get inside and somehow charge the battery up with a crude hand made rig or something. Assuming that the failure to boot is simply lack of charge. As it was the last time this happened. And needed TPdebrick so that it would charge up in that too low state. The last resort option would be get inside it or whatever other method needed to copy the data off of the internal storage (part seen as SD card) in the state it is in. And if the storage can somehow be wiped from there sell it for parts if it ends up not repairable.
It could also be a dodgy Usb connection/board on the TP several people including myself have had this problem.
Well if tpdebrick got it up and running before can you not repeat the process to enable you to charge the tablet. Then you'd be able to install the tpcharge app and go from there ...
Does the back of the TP get warm/hot after charging? On my TP the back area near the volume buttons gets warm after being plugged in for a few hours.

When charging any old day while I am using it I have noticed that area get warm. Just like the cylinder of the charger getting warm almost hot. Neither of that is happening which leads me to believe there may be something more wrong than just the simple yet not so simple problem that TPdebrick fixes. I've ran TPdebrick on it several times now twice before posting the thread and twice after. In completed it's execution with "all done" message. The port itself appears to function otherwise TPdebrick would fail before completing due to a USB connection failure. At least it seems to me it would fail as a result of that. Is there a way any of the parts can be tested for failure to figure out what has failed? Again assuming that something has gone bad internally on the TP. It has been plugged in for now 48 hours only interrupted by running TPdebrick. Of which I could run it again and get the info from the log I previously posted to see how it has changed. I have no idea what the numbers mean other than the battery percent being reported as 0.
I forgot to mention previously that it was plugged in at the time the battery went to 0%. Something I had not expected to occur. The battery icon in CM9 indicated charging with the lighting bolt icon as I had seen the icon just before it auto shutdown. Something I didn't give much thought to as that had happened one time a long time ago when I still had only webOS on it. Except webOS didn't let the battery get too low and it simply booted back up a minute or two after the charger was reconnected after it auto shutdown. So I guess if there is anything I can do to figure out why it isn't charging to know what needs to be fixed and if it is worth fixing and I'm able to fix it then I'd like to fix it. Otherwise I'll need a way to recover the data off of the storage so I can at least not have to start completely over with most of it. Nothing real important on it or anything that if lost would be detrimental just time lost in game progress and related and having to download oddball files for other apps again.
Just out of interest ... my touchpad that was not charging properly thru the usb port still managed to get thru the tpdebrick process to the "All Done" stage. However, it would only take a maximum of 100mA, even off the 2A mains charger. Changing the usb port resolved the chraging issue.
Peace
Edit: also, a touchstone - wireless - charger will eliminate a battery vs USB port fault ...
I have good news and bad news. The good news I'm able to charge my TP with a charger other than the official one. I tried my smartphone charger which is significantly lower amps. In 9 hours it has charged it 30% while it remained in the powered off state. I booted it up a few minutes ago hoping that it had charged it up. I powered it off again and will charge it to 100% before using it.
The bad news is the official chargers cylinder is shot. This is the second official one I have gone through since purchasing my TP during the fire sale. So I'm not sure what I'll do about that. I only really use it as an ebook reader right now and as an alternative to some things I use my smartphone for when I have both available to me. Considering my netbook is in need of replacing due to a failing charging port I am looking to get a windows 8 pro hybrid tablet (ex acer w700) which would effective replace both the netbook and TP. Leaving the TP as a much more of an experimentation device.
mine does not charge in android OS after installing CM 4.1.2 over old cherry kang
im getting current500mA in touchpad chargetest if connected to PC back 2.0 port, charge icon does not appear
charges if on webOS
Having the same issue as serialteg described. Just flashed to 10.2 (09/20 NIGHTLY) and TP cannot charge on CM. Switching back to WebOS, it's being charged.
Fixed. The infamous MTP issue was what I had. Solution found.
Hi there,
My phone is not charging very well, I knew I had battery issues so I recently purchased a new battery.
I have been using CM 10.2 nightlies.
The troubleshooting done so far:
Wipe data/factory reset
Install stable CM 10.1.3
Cleaned usb port
Changed from MTP to usb mass storage
New battery
Nexus 4 cable and charger
Note 2 cable and charger
SGS4 charge cable on PC usb
My phone is pluged and it discharges instead of charging, NO SERVICES OR PROGRAMS RUNNING
Screen off... it discharges to 1% faster
Should I run stock rom on this big ass boy?
Should I get a new USB port (I thinks this is it)?
Should I try a different kernel?
Or should I run a different radio?
Thanks in advance

How does it work while the Note is turned off ?
Does your Note recongnize if it is charging from USB or AC wall charger (must be on of course) ?
Your new battery is Samsung or OEM battery?

Galaxy Note 2 discharging if used while plugged in
My note 2 is charging very slowly while on (10% per hour), charges about the same pace when plugged in. Only just started happening recently, I suspect from the newest android update. on AC it used to charge while on in 4-6 hrs, depending on whether or not i was using it while plugged in. Did the cleaning battery / reset / clear cache etc and calibrated the device with Battery+ app. Phone still discharges at normal pace when not plugged in but 10 hours is a really effin long time for it to recharge, no?
I used to be able to use it heavily while plugged in and it would just stay level, and still charge on light usage. For it to lose charge while plugged in seems wrong.
I installed JCSullins 4.4.4 CM 11 from 9/13/14. Thanks to the Toolbox, the process went extremely smoothly. I ran into a small issue though. The battery would charge properly overnight for the first week or so. Then I noticed that the battery wasn't getting charged (no charging indicator) but a reboot would fix the issue and the battery would start charging again. This morning, the battery won't charge at all, even with a reboot. It shows 51% and discharging. I tried different chargers but none seem to have an effect. I haven't had a chance to plug it into a laptop yet to see if the USB port is broken. Has anyone else had battery issues after upgrading? If the USB port is indeed broken, would a charging dock (Touchstone?) charge the TP?
Might be Cable problem
Hi,
I've been using this rom for about 3 days and didn't noticed any problems in charging. What I had in the earlier days is battery drain in lowest clock frequency. Then i rebooted it 5 to 6 times and then problem got solved also deep sleep started working.
You can check the cable and the charging adapter. It might be the blacksheep.

Thanks for your reply. I tried using other chargers and cables and nothing seems to make a difference. Oddly enough, the charge has dropped to 15% and if I leave it plugged in all day/night, it doesn't drop beyond whatever % it was last at. As an example, if I leave it unplugged and the charge drops to 10%, it will stay at 10% when the TP is plugged in. The battery icon also shows charging for a minute or so, then stops again.
Just as a follow, at least one other user has this problem. See the 4.4.4 thread in the developer section. Unfortunately, I cannot post in a developer until I have at least 10 posts. Sigh.
Here's the link to the other post: linkie
phone says 100% but says 80% when off charging
Tried:-
1. 2 different battery callibration apps
2. charging 100%, depleting battery. repeated process a couple of times
3. Switched to Stock (Rooted), 2 Custom ROMs (Waited till it was 100% on both on and off before flashing)
Notes:-
1. Battery seems perfectly fine (takes a while before depleting and doesnt deplete before 0%)
Currently using stock rooted
l would start with replacing the cable and charger to make sure you are getting a full charge. Then monitor the usage time on your phone over a few weeks and see if the time to empty is getting less that is a sure sign of a bad battery
Recheck with another fast charger. Generally, we cannot say if is a faulty cable or you have an faulty adapter. I hope the device chargeboard is not shot/motherboard driven related issue. Also, have you recovered the device using Samsung Kies- Emergency firmware recovery?

With original charger it takes 6hrs!!! Holy ****
I think its a usb port problem for sure.. Do one thing while connected to the charger go to device maintenance and open battery menu and see if it say charging via AC or USB if while us8ng the original charger it shows Chaging via USB then certainly its the port that has gone faulty..
Hit thanks if helped
Hello everyone! Though its not the right place to ask the question but I have been seeking solution to my problem from months. Long time before, my Galaxy Note II started to behave differently. Whenever I charged it completely, the phone worked normally till 75% to 80% and all of sudden a =low battery warning indication appears and phone proceeds to shut down. I tried changing ROM and calibrating the battery again but nothing worked. Finally I replaced the battery with a new one and also clean flashed another ROM in a hope to see if the problem is gone or still there. But to my surprise the problem is still intact. Now, when I turn on the phone the battery is 90% and when I keep using it, it drains normally, but as soon it reaches round about 80%, it turns off randomly. When I turn the phone back on the battery is still at the same percentage level at which is turns off. I believe there is not an issue with the battery. Please help me what to do, I am using TWRP recovery that doesn't gives the battery stats wipe option too. Should I flash a new ROM again? I would greatly appreciate if someone please helps me in sorting this problem.
What I have already done!
1. Replaced the battery
2. Changed the ROM
3. Re-calibrated the battery

I have noticed the same issue, I think. I suspect it is a general bug.
Guys, try charging your phone while in Android. When it reads 100%, switch off your device. Either leave the charge cable attached or reattach it after you have switched off. Now wait for the off-line charging icon to appear. Unless I'm mistaken, the percentage won't correspond with whatever your phone reports while your in Android. If Android says 100%, this will be a lower number. And off-line charging will keep on charging until you reach 100%.

Sorry for the late response. Internet finished, had to wait until the renewal date. During this time, i wiped the rom and re-installed it (Khongloi V11). Since there was no internet, i didnt sign in any accounts, Switched off the location. The phone surprisingly took 3 days before reaching 0.
Indeed, it says USB Charging 6hrs. I sometimes keep plugging and unplugging, it changes to A/C 2hrs.
I have this problem too. But I change batt_capacity_max to 1000, phone on 100% phone off 100%. If we recharge to full it will return to the same state (phone on 100, phone off ~80) so i need to change again. I don't know if this destroy my battery life ? I don't know why. I thought I'm the only 1 who have this problem? (sorry for my bad english)
I think this may be a software/firmware problem, not a problem with the battery.

I figured that was the problem but i tried it with three different roms (Khongloi V11, Final, Stock).
Maybe it's some kind of battery protection thing created when your battery is old or something?

The various ROMs may all use the same battery raportage code, which doesn't account for this discrepancy. After all, most ROMs are just fancy reskins of stock Android.
That said, maybe Samsung support can shed some light on what's going on.
On a side note? Is there anyone who reads this thread, whose reported battery charge (in percentages) is the same in Android as when the device is switched off and charging?
So... any solutions?
