Urgent help about the battery

I posted this question before, but no one answered. But this problem drives me crazy!
My Kaiser turned off when the battery was running out.
When I connect wall power to charge it, the orange LED indicates it was charging, but just few seconds later it automatically boot, and the orange LED was off.
The problem is, it can't boot into OS due to low battery(it only shows "Smart Mobility", but can't even enter bootloader mode) And only if it boots into OS successfully, it can be charged.
Anyone met this problem on any other devices before?
How can I stop auto boot when charging?
What can I do?

That must be something specific to the rom on yours... mine does not automatically boot when when power is applied (assuming it is off, not just in sleep mode), and it charges fine when powered off.

Thanks
I use the ROM from this forum
RUU_Kaiser_HTC_WWE_1.56.405.5_radio_sign_22.45.88.07_1.27.12.11_Ship
What is yours?

I'm just using the stock AT&T Tilt rom.

Here's the fix!
Yes, I've had the same problem a few times on my Vario (Wizard). Very annoying.
Here's what to do:
- Take a mini-usb cable (the one you use for sync and charging from a PC) and cut off the mini-USB connector
- Strip the wires
- Take the battery out of your TyTN
- Carefully connect the ground wire (black) with the ground connector (-) on the battery. Fix it with clear tape.
- Now do the same with the (+) (red wire).
- Attach the USB cable to a running PC and let the battery charge for about an hour. After that, put it back in your phone, you'll be able to boot it up and charge it the regular way.
Yes, it costs you a cable, but it solves the problem.

I think you misunderstood. The problem is that the phone only charges when the OS has loaded completely. So if you really run your battery out completely and there is not enough power in your battery to boot up the phone (read: it turns off again before the boot has completed) you won't be able to charge it the regular way. SOMETIMES a heavier charger (2A) does seem to be able to charge the battery even with the OS shut down, but most of the times it won't work anymore... see below for fix.

Based on this, it sounds like it is starting to charge without the phone booted (orange LED on), but for some reason it then automatically boots up, then crashes because there's not enough power(??)
But if the problem IS that the phone only charges when the OS has loaded, that is also not how my phone operates. In fact, that even goes against the manual, which tells you to plug the phone in (without turning on the phone) and let it charge fully for the initial charge before turning on the phone and allowing it to boot.
Sorry if I misunderstand, but neither way is how my phone operates... it can charge without the OS loaded, and the phone does not automatically boot once power is applied.

Not sure I fully understand what's going on here but, I am wondering if the power on/off button is stuck in (i.e the micro-switch is clicked in and not releasing). I cannot think of any other reason the device would turn on when connecting the charger if the device is powered completely off. ( Except perhaps shorted connections in the Usb port)

To SteRo:
Thx a lot for the solution, I tried, but still doesn't work.(I charge it more than 2 hours, and still can't boot into OS)
To mikechannon:
yes, it happened. :-( the power on/off button is NOT stucked. And the device is powered off completely.
To All:
Thx for your reply. What I mean is almost what dscline said:
It starts to charge without the phone booted (orange LED on), but for some reason it then automatically boots up(around 15 sec after I plugin power), meanwhile orange LED is off. But it can't load into OS, just re-boot again and again because there's no enough battery. That makes it's impossible to charge, 'coz it's only charged when the OS has loaded completely.
Anyway, I called customer service to ask them replace the battery. I may try to use different ROM and see what will happen. I'll post the result here.

It's also possible that it has nothing to do with the battery or charging at all. I just checked mine, and the charging indicator is lit with the unit off, but it does go out for a bit during the boot processes, then comes back on again. So what you're seeing with the charging light is normal. It may simply be that there's something corrupted, or some other failure with the device, that is causing it to not boot properly, and get stuck in a reboot loop. If so, it will probably do the same thing with a completely charged battery. You may have just been assuming that it was related to a low charge.

That's what I'm worry about,, Coz I can't boot it by SteRo's solution.

okay... they say trouble comes in three's...
Yesterday I flew to Asia, 20-hours with a full charge. No suprises during the trip. Checked email from Narita during the layover, no prob. But after I arrived in Taipei I received the low battery warning. Plugged in my usb-to-usb (notebook to kaiser) cable and "no charge light"!
This morning I plugged it into a ac battery charger and waited for >10 minutes, still no charge light.
Now, at the risk of a battery, I'm attempting to charge the battery removed from the kaiser using the previous mentioned method. In an hour I'll test it.
This afternoon I'll pick up a new battery charger and spare battery.
In 14-months with my trusty TyTN (cht9000) I never once had a problem like this... I'm a little bummed right now...
[update]
okay -- battery is okay and can be charged externally (using the two wire method or an external battery charger). BUT... the device still won't take a charge using either a direct AC adapter or a USB cord. This was also retested after performing a hard-reset. Not a good sign folks.
The charger works (connected to a Trinity), so it's not the problem. They battery works (charged to 45% after 45-minutes connected to an external battery charger). The HTC OS after a clean hard-reset used to work but now doesn't, so it's unlikely it's software related.
I've made no other modifications to the bootloader or SSPL... everything is original stock. Wish I had my TyTN with me right about now...

Sounds like something I had on my previous TyTN:
The power connector was a bit flaky on my charger at home. So when I'd hookup the powerlead it would charge to 10 secs or so and then no longer charge. I had to put some pressure on the connector to have it continue to charge. So I put a ballpen on the powerlead, just under the phone, when charging.
It's a long shot - hope of use. When you've connected the phone to power, and the orange light goes off, try wiggeling the connector a bit - see if that helps.
Hope of use.

Re
OK,
I've got excactly the same problems... I dont want to make you illusions, but you cant solve it and you need to send it back for repair. Your usb connecter on your tytn is broken...
first i will tell my story...
My tytn did excactly the same, shows the led, powers on automatically (normally it don't do that, so it;s not a rom issue) and then powered down in the smart mobility screen. I tried 4 chargers, and 2 battery's. with a full battery it will power on and load windows, but unable to charge. with the empty battery it will power down in the smart mobility screen. soft reset, hard reset, it won't work.
You can check if it's the same problem, by attaching it to your usb on your computer and call up the bootscreen by pressing the camera button and stick your stylus in the soft reset hole. If it comes up with serial instead of usb, then your device usb connector is broken.
BUT, you can charge your battery in a very strange way i figured out. since i am on a buisness trip i need my phone and don't send it back!!!!!
ok, this is what you have to do, plug in the powercable, call the hard reset screen BUT DON'T APPLY!!!! you will notice it will not power down, so just leave it on this screen for a night with the cable connected. you don't see the charging light, but actually it is charging. for me this temporarely solution works fine... but when i'm back in about seven weeks i send it in for repair.
Hope this will help you!

Swiftgs:
Many thanks for your insight -- you are correct, in bootloader mode the Serial shows instead of USB. I just purchased a spare battery (1100mAh, made in Taiwan) and battery charger for US$17. It'll get me through my business trip, but this is disappointing. As I mentioned in my earlier post, I used a TyTN for 14-months (July 2006 to Sept 2007) as my primary phone, recharging it daily via the USB connector and on a desk charger in my office. I can only conclude that if the USB is physically damaged (not evident visually), then it is not as robust as the USB port used in the original TyTN. The strangest part of all is it worked perfectly until the battery level fell below 10%...
FWIW: I purchased the phone through R&D Marketing. Ron Webber quickly responded to my note and gave me a contact at HTC America. I'll follow-up
after I return and report my experience.
Cheers

well, thanks for all of your replies/infomation.
I tried evey possible methods mentioned above, unfortunatelly none of them works :-(
and the most depressed thing is I filnally get a new battery, but it still doesn't work!
So I sent it back to repair, cross figure...

It works
I would like to thanx 2 SteRo for his advice. I am using Qtek 9000 and had the same problem. Battery was empty, and I tried many times to turn on my PPC, but without success. All the time when red light appeared after 10-15 sec display become black and tried to restart from boot again, and it's happened many times. Finally I thought that I just can trow my Qtek, but seeing your recommendation decided to try. I took USB cable cut it and strap the wires. Connecting red on (+) and black on (-) after 1 hour charging I was able to start my PPC, to recharge battery by 100% and it is working now OK. I must check duration of the battery tomorrow, because reason why I discharged battery was automatic turn off of my PPC when it was on around 45-50% battery capacity. Tomorrow I will check how it's working when I recharge battery again.
Dear SteRo you are the king.

Dead Screen or Nearly Dead Battery Issues

Okay, first thing to mention is that I have searched for information on my issue and while I have found (and tried) solutions that approach my goof, I need to post this:
Last night I finished reading from Kindle app, hit the power button to shut off the screen and laid it down. I know I should have plugged it to recharge but too late now. I am running CM nightly from 07172012, so I know I didn't download the nightly CM battery issue versions.
This morning the screen will not light up; I have tried charging it, hard reset with power and home screen buttons for 15-20 seconds (and longer), and nothing works. My concern is that the screen is dead. I connected the touchpad to my laptop and I get the connection sound from the laptop; it sees the TP but does not accept it as a portable storage device. Device Manager lists it as: QHSUSB_DLOAD with driver(s) not loaded.
When I try the volume rocker button I do not hear the small audible ping as volume goes up or down. Of course, with the resets, who knows where I am in the OS (or even if it is WebOS or Android).
I really didn't want to be a noob and post this, but I need some advice from the brethren here on XDA. Thanks in advance.

It seems to me that it's not even booting if your getting that strange device in device manager. Try the webos recovery tool from hp. It may help. Although it will wipe android off.

my son-in-law is in the same boat. Nothing he does wakes it up. I believe there are tp's out there with this hardware issue. I let my tp battery drain completely. It powers down around 4% battery. I place it on the touchstone, it charges backup and boots into moboot, then webos. I've done this twice. no problems. If it's under warranty still, send it in.

If you have a touchstone charger put it on that and leave it for a couple of hours and it Will come back to life.
See this article by Reverend Kyle http://www.reverendkyle.com/index.php/articles/146-hp-touchpad-charging-issues-solution
I hope this helps.

I've had multiple instances of black screen of death failure.
The latest one I had, I was able to restore by using a standard USB to micro USB cable (and recently NOT the HP OEM cable) to connect to the computer I usually use to sync or use HP web doctor with.
Same symtpom as the OP, get the three dings when connecting the touchpad to the computer, no responses and the QHUSB driver load error. HP charger wouldn't chage it, touchstone would not charge it.
Anyhow, I left it connected for a few hours to charge connected to my PC. Then, I disconnected from the PC using the large USB connector and reconnected. Whamo, got to the bootloader.
I believe what happened was I trickle charged the touchpad enough to get the touchpad to boot.
You can try the various hard boot keypresses too, but wait for a few hours while trying to trickle charge the touchpad via the computer USB.

Update
Okay, so I followed the old rule of doing the simple (and/or free) solutions first and then move on.
1) I set the touchpad on the touchstone for several hours yesterday - no luck
2) I connected the touchpad to my pc through the USB and let it charge - no luck
3) I let it be plugged into the standard charging plug all night - no luck
4) I prayed to the great old god Cthulhu - no luck
My only option remaining is to use WebOS Doctor. One question on that: in all the literature I have read thus far (and perhaps I am mistaken), I need to be able to get the TP into USB mode to download the corrections/reboot back into WebOS. Is that right or can I expect that when the doctor sees the mangled mess of an OS through the USB connection, it will know what to do?
Again, as always that for the previous posts and for the support.

Another piece of black magic that worked for me and is worth a try as it is free. Connect Touchpad to standard HP brick charger plugged into power outlet. Unplug cable from charger, count to 5, plug it back in, count to 5, take it back out. Repeat the cycle until you get bored or until you get a red charging symbol. If you get the latter then let it charge up normally and you are back in business. The theory behind this method is that it takes a few seconds on plugging in for the circuits to realise they "shouldn't be charging" and this allows a little bit of charging to take place on each insertion. Repeat enough times and you get enough to kick start the proper charging. In my case about 20 times did the trick.
As I didn't want to get into this situation again I then set up a Tasker process to power down th eTouchpad if the battey charge dropped below 8% and I've been OK since.

RIP Touchpad / EOT
Well, I had to wait a day to get my hands on a WinXP laptop; I upgraded my Dell to Win8 about 3 months ago and WebOS Doctor does not play well with Win8.
While that time passed, the touchpad finally gave up the ghost. There is no power left in the TP. When I run WebOS Doc the laptop cannot see the TP connecting via USB. I also checked by connecting the TB to the Dell, since it would at least see the device. Not any more.
My thanks again to those that responded. I did try the plug in, plug out with 5 second waits between, just in case. You never know. However, after 50+ attempts I had to call it a no-go.

does your home button light come on at all? Are you able to see moboot bootloader at all or are you able to start the tablet in webos recovery mode by holding the vol key while powering it on? are you able to ./adb connect? Also I've never had much luck with the resest method youre using, holding down the power and home key, I always hold down the power key and press the home key 15 times, when I get hard freezes and lockups, it's always worked.

Mine is in the same boat for a couple of months, removed battery and charged. Boot loader is borked I get only get a qualcomm usb device but nothing thats of any use for webos doctor or qualcomm tools. We'll have to wait until someone figures out jtag or how to replace the bootloader with qualcomm tools. I'm amazed with the number of touchpads out there that something hasn't leaked from hp to fix it. Anyone got friend in hp or qualcomm :angel:

OP Update
Well, I thought this was a dead issue but here is the latest.
After wallowing it a pit of despair the likes of which can only be described as wretched, (I even coveted my wife's TP up close, almost giving into temptation and swapping decals to reverse ownership) I looked outside of XDA and did general Google searches and happened upon this site:
http://forums.webosnation.com/hp-touchpad/299256-dead-touchpad.html
After reading a bit I realized that the touchstone may be able to recharge the dead battery even though fully drained. I began the quest that Friday morning the 24th of August, after verifying that my Dell laptop did not see the TP when plugged in via the USB cable.
I just did a quick check and the laptop now "sees" the TP when connected. Still no luck on booting into Moboot or the USB icon screen - neither Power and Volume Up or Power and Home buttons achieve anything. But I am glad to see that the touchstone has placed enough charge into the battery that the laptop is aware of the TP when connected.
I believe that given a few more days on the touchstone I should be able to boot into moboot.
@ haxin - I have nothing. Not a single light from the Home button - my only evidence that there is SOMETHING going on is when I connect the TP to the laptop and get my connection "sound". Again, I have high hopes that the touchstone will get me where I am going, albeit at a snails pace.
@ paddy - Yeah, I hope that when (if) I get to a lit screen, I am able to move past where you are at. My big concern is that I am toast even with a semi charged or fully charged battery from the touchstone.
I will update later on. Again, thanks to all for the input and probing questions. You have made me think harder and work a bit longer on this project.

OP Update - 31 August
After 7 days on the touchstone, the touchpad is currently showing the low battery charge icon; I have now plugged it into the A/C adapter.
Each morning I have picked up the TP, held down the power button and held the home button for 15+ seconds. Today it worked, turning on the screen for the first time in a week and letting me see the low battery image.
In my quest to resolve this issue, I have read so many variations on what buttons to hold and how long to hold them that after awhile you end up considering the possibility that SOME of the button options are not correct. That the operator has booted their TP up, but they misconstrued the actual solution; how else can you explain the idea that HP built so many different button combinations and hold times to boot a TP from a nearly or fully dead battery state?
Anyway, I will continue to post updates until my beloved TP is back to running CM9.
And to all those who gave their TP up because the battery got too low; find a touchstone or other "trickle" charger solution, connect and let it sit for a week or so.
Thanks!

Glad the Touchstone worked for you , don't know why it has taken so long to charge but when your up an running properly Llama is a good app to install as
A:You can set alarms for when the battery gets to a certain level/levels
B:Have it shut down when the battery gets to a certain level.
I use 20% for an alarm and 10% to shut down which allows me to sleep easy and not worry if someone else is using it . .

I am up and running. I most definitely will load that app on my TP, plus my wife's and a coworker who bought a TP because of mine.
I don't know either why it took so long; I am just glad it worked and I have it back. I am on it right now.
Thanks again to all who provided feedback and guidance. This is why I love XDA.

HP Touchpad sleeping and will not turn on
Just a note to those HP tablet owners who experience the Black screen of death or sleep of death.
I am the proud owner of 4 HP tablets and two of them so far have had the black screen of death. I have read forum after forum trying to get answers to this problem. There was only one posting that has made cense to me. Someone posted that the tablets symptoms are very much like when the Phones use to go to sleep. The solution was to disconnect the battery for a few minutes then plug it back in. Then simply hit the hold the power button down to turn on the tablet.
The problem is taking the TP apart. There is a video on youtube on how to disassemble the tp. It is a little annoying that you have to go to such lengths to reset the hardware but HP will charge you 250 dollars to fix the problem. After you watch the video on how to open the TP, remove the 3 little screws holding the battery. Now slowly pry the battery up, they use double sided tape to hold it in place along with the screws. Wiggle the battery side to side and try to disconnect the battery connector. This can be done without removing the boards in the TP. Wait 1 min then try to replace the connector in the socket. It is on the underside of a board so when you have it in place use something to make sure it is tight. Plug the charger in to the USB cable. Without closing up the unit hold the tablet power button in until you get the battery charging symbol on the display. Let the unit charge while it is still disassembled. Just in case you have a problem. Once everything is operating disconnect to charger and replace the battery screws, now snap everything together.
This was the only way I was able to fix two of my four TP's. I am sure I will have to do this again because my kids always let the tablets go dead and they don't pay attention when placing them on the Stone for charging. If the tablet is not properly placed on the stone the tablet will not charge.
Hope this helps.
This by far is the best tablet for the money anywhere.

I realise this is an old thread, but I recently had a reoccurrence of the black screen of death issue and thought given the number of touchpads still out in the wild, I would share my experience on the off-chance it may help somebody.
My first experience of the black screen issue was a few months after having my touchpad (many years ago). The screen just went black and no combination of holding the reset keys for any period of time would restart the unit. I had suffered lock-ups before and found the reset combination to be successful, but this time none of that worked and I had effectively what appeared to be a dead unit.
Having contacted HP, I returned the unit under warranty and a unit was returned working. I say “a unit” as I was never quite sure if it was the same unit or a refurbed unit, but to be honest given the speed the units went out of stock during the fire sale, I was just glad to have a working unit again.
Well this week after several years of use including the installation of Android, the black screen occurred again. As before, no combination of the keys / holding for a period of time / pressing them a number of times etc had any effect. The unit was three quarters charged and I was using it up till the point the screen went black. :crying:
Given that the unit has no warranty and it was “dead” anyway, I decided to take it apart. Despite watching YouTube videos, this appeared to be more troublesome than I thought, but eventually I was in. Interestingly, the backlight on the screen was still lit, suggesting the unit was still powered. I did consider disconnecting the battery, having removed the screws as per the previous poster, but mine seemed to be well and truly stuck down and I felt I may damage it prying it away from the base.
However, looking around inside the unit, I spotted what was clearly a surface mounted switch that faced upwards towards the back of the screen. Out of interest, I pressed on this switch with my finger nail and my unit powered off (shown by the backlight turning off). I then pressed the normal power switch and the unit powered up as normal. I have attached a photo of the switch which resides close to the popout tab with serial numbers on that can be found on the right hand side of the unit.
It does appear strange that HP put this “reset” button inside the unit, facing inwards rather than outwards where a small hole in the back of the case could be used to press it. So if you do get to the opening the case stage, consider this as an alternative to prying the battery loose. Also if somebody can work out a way to make the button accessible from outside the case it might be a useful modification.

Oh I was so keen when I came across this post. A Reset Button! How great would that be?
Tried it, unfortunately it did not resurrect my dead as a doorstop TP. I was so hoping...
I just put a 'new' EBay battery in it a couple of days ago and tried trickle charging with a 1000mA charger for 24hrs. No joy there either.
All I get when I plug it into the PC is that it shows up as a "QDLoader 9008" (QHSUB_DLOAD driver) .
No flicker of life or light whats so ever...

Try to borrow a Touchstone conductive charger if you can. It's the only thing that has worked for me when it has totally drained down.
All the best.

That's what I was thinking - no joy there either... It is not even showing signs of getting the least bit warm.
I keep thinking and hoping that there is some way to resurrect this one but I may be wrong...
It's currently trickling on a 1000mA charger. Tomorrow I'm going to try the Touchstone behind it.
If that doesn't start something then I'm going to yank the new battery and along with the old battery charge them like an RC device.
(if I can ascertain the proper way to do that --- )
_mr

After several days on the trickle, still no life.
Took it apart at lunch and with the battery still connected to mobo it is showing 3.1V across the red/black. So I figure the battery
is good. Looks like the mobo is gone.
Not sure what else to try.

Touchpad is charging but not oooting, webos doctor not working

Hello everyone,
I installed a JB rom a few weeks ago on my TP (can't remember which one)...it worked for a little while, then i wanted to flash something additional and it seems to be bricked ever since and has been laying around...which is why I can't remember what exactly I wanted to flash
Anywho, if i connect it to the PC the notification LED on the home button is blinking..but that's it. no combination of power/voldownup/home button seems to be working and when I try to run webos doctor it doesn't recognise my device.
can anyone please help me?

When you say bricked. Do you mean stuck in a boot loop wouldn't turn on etc.
Have you had it connected to the stock charger or better still on a touchstone and if so for how long.
The more information you can give the better.

No it doesn't turn on at all, screen stays black.
It's been connected to what i think is the stock cable to my pc (there are too many Micro-USB cables laying around here ) for about an hour now and i just put it on the touchstone (LEDs are still flashing)..

Leave on the Touchstone for at least a few hours preferably overnight then hold the power and volume up buttons for at least 30 seconds if nothing happens do the same with power and home buttons and post any progress or lack of, but the first thing is to try and put some charge into it and the best for that imo is the Touchstone.

The stock cable for the touchpad has a silver dot at each end. I have two touchpads ad the connection is very loose and unreliable. It often won't charge. I bought new Micro USB charge/sync cables and charging is no longer an issue.
The USB port on your computer is not powerful enough for anything it trickle charge. You need a stock touchpad charger.

Well i charged on the touchstone and then after a few hours i was able to boot into recovery and flash a new rom problem solved, thanks anyway!

Tablet won't charge when on (android and Windows)

Hi everyone! Today a very strange thing happened... I was using my tablet with Windows, with a usb hub attached to use a simple mouse. This hub has a micro usb output, so that I can charge the tablet while plugging in usb devices (that's exactly the one techtablets uses in one of his videos about this tablet). All of a sudden it stopped charging, so I tried rebooting: NOTHING. Then I switched to Android, but still no luck!
I'm happy I see that it charges if it's completely off, but I don't think it's normal!
What do you suggest me? This tablet is fundamental for me, as I study with it!

Anyone who could kindly help?

Same here and notice this after your post here. Windows notice that i plug in the charger (screen brightness was different with pluged in charger) but doenst charge.

I'm thinking that it might be BIOS related... Unfortunately I can't update it (I have 2.02 version already), or at least sort of reflashing it, cause I don't have a usb keyboard... Can you make a try? Cause it's weird it happens on both Windows and Android! I also noticed that if I have it off, charging, right when I trigger the power button and the teclast logo appears, right before the choice of the OS, it stops charging..

i have same problem, do you resolve it for present? how do you use your tablet?

Mine was a bit temperamental and as described above for the 1st 6 months but now it will not charge even when off unless it is left for days. Then no where near full charge.

I had very similar problem on my old teclast c6j6 tablet a year ago .
It seems my usb connector in tablet was too loose after few months .
I opened and pressed ( squeezed ) usb connector and was work again fine .
For the time being I connect and disconnect usb cable very gentle on all my teclast tablet and is fine .

I have the same problem. The tablet will not charge while powered on and starts charging right away as soon as it powers off. I do not have to wiggle the cable or anything. ON = not charging, OFF = charging. It's very unlikely that this is caused by a bad connector.
Be careful when you use Android. If Android shuts down because the battery is low, the tablet will start as soon as you connect a power cable. The tablet starts up, stops charging because of this, shuts down because the battery is low, starts charging as soon as the tablet is powered down, starts up, stops charging, shuts down, starts charging, starts up, stops charging and s on. Viola: you have a boot loop.
I wrote about it here: http://forum.xda-developers.com/x98-air/help/dead-battery-bootloop-t3243993
There is a fix which requires some soldering. This is a YouTube video which describes the procedure:

Unusual Dead Battery Problems/Behaviour

Hello, longtime reader, first-time poster.
I am trying to revive an HP TouchPad that is behaving strangely. Let me first start with the background of this tablet.
Background:
I believe that this TouchPad was bought in the fire sale. From the information I can gather, it was barely used. The only major hardware problem with this tablet is that the micro USB port is partially broken. To charge the tablet, I have to bend the cable toward the back of the tablet.
The Problem:
I can charge the tablet from my computer, anything else does not work (I assume it is because of the amperage). When I plug it into my computer, the home button immediately lights up. However, the left side of the home button stays on longer than the right side (the left side lights up for about 4 seconds and then alternates to the right but quickly goes back to the left). I this normal? I have also noticed that even after I unplug the TouchPad, the light still stays on for some time. When it is left charging on my computer for some time, it flashes the battery with ? symbol. I have also seen it go through a loop where it flashes the home button, then shows a low battery icon, and then quickly shows the battery with ? symbol.
I have read that you need to perform the tp debrick to fix the battery with ? symbol. However, when I plug it in and hold the correct buttons (for longer than 30 seconds), tp debrick v005 says something like QDSL mode not found (I forgot what it said exactly). I think that this is due to the faulty micro USB port, as when I plug it into my computer (which is running Windows 10) and hold the same buttons, Windows says that I plugged in an unknown device and that the device is not responding. When other people plug in their TouchPads that are in the same state, Windows gives them a name that is similar to QDLS or something like that. I am thinking of getting a broken TouchPad off of eBay and transferring its USB board to my TouchPad. There is an iFixit guide on how to do that. If all goes well, I think I will be able to perform the tp debrick.
So, I would appreciate it if anyone had any suggestions for me. If you need more information about the tablet, just ask. Thanks.

Well, I bought the broken TouchPad. If anyone has any tips for opening a TouchPad without breaking the clips, I would appreciate it.

When the Home button LED blink side to side , it means the battery is very low, the Tablet is working properly and not brick.
A charger of 5.3 volts 2.0 amps, must be use. Nothing else, no usb on computer or any other charger.
The battery will not take a charge using any other type of charger and will not boot.
It could take a couple of days for a depleted battery to be fully charge or boot up.
My recommendation is to use the correct charger before trying to fix the usb board.
It is very easy to change any of the internal components, is all screws. When removing the screen make sure to use plastic material to prevent damage to the edges. Use two or three plastic openers to slowly open it from different parts. Some clips could break, but it can be snap back again even with few remaining clips.
This is a guide that explains the symbols and what to do:

Thank you, HP_TOUCHPAD. I will leave my TouchPad on the original charger untill the broken TouchPad arrives, which will be next Wednesday or Tuseday. How ever, I do not under stand how charging it on the original charger will give it any power. If I plug it into my computer, the home light imdediatley lights up. If I plug it in to the original charger, it does not.

Is the original charger USB cable the same that it came with the Tablet?
As you know the USB cable can be detach from the charger.
Are you using the same USB cable from the original charger when connecting to PC?
The LED light should blink either way, when connecting to PC or original charger.
Try connecting another device to the original charger and see if it works.

The original cable broke, so I am not using it. I tested the original wall charger before I plugged the TouchPad in, so I know it works.

Not all USB cables are the same, make sure the cable works properly for charging.
If the Touchpad is getting power when connected to PC but not from the original charger, then something is wrong with the charger or cable, not the Tablet.

I have tested both the cable and the charger, and both work properly. I have noticed that the charger is a little warm but the TouchPad is not. It has been on the original charger for around 2 days now.

For all lithium batteries to take charge when depleted, it must be in a warm environment. It will need to be above 85 Fahrenheit, is all a chemical reaction. Also try this, without the USB cable connected to the Tablet:
Press and hold at the same time Power + Volume Down ( key closer to Home ) and Home for about 1 minute or until the Table boots or the LED blink, then connect to charger. Look at this guide picture:
https://forum.xda-developers.com/t/hp-touchpad-debrick-linux-live-cd.4189245/
Sometimes the Tablet will freeze and a force reset is need it to make it charge. It will not take charge when is in a frozen state.

Sorry, I did not have enough time to try your suggestions. However, the broken TouchPad came but it's screen isn't damaged like in the listing pictures. When I plug it into the original charger, the home button lights up. I will let it stay on the charger for the night.

I have left the tablet on the charger overnight. It is still flashing the home button light. I tried turning it on this morning but it didn't turn on. Both the charger and tablet are somewhat warm. How long should I wait for it to turn on?

Good news! The TouchPad I bought from eBay booted to the battery with ?. However, since this has a functioning USB port, I was able to perform tp debrick v005 on it. It successfully boots to WebOS and Cyamogenmod! Thanks for all the help! This isn't the original tablet I was hoping to revive, but at least I have a working one! Also, what is the latest version of Android that has everything working on the TouchPad? I want to upgrade it from its current Android version.

I need help. When I try to transfer the Android files to the HP TouchPad using TPtoolbox, Windows says that there is an F drive that I have to format before I use it. In the tutorials, a drive labeled HP TOUCHPAD or something like that shows in Windows, and you can put the Android files inside of the ttinstall folder. Should I format the drive and if so, what format?

The TPtoolbox can only be use to flash an specific ROM, and that was 10 years ago.
Follow this guide that allows to flash all Android ROM ever made for the tablet:
https://forum.xda-developers.com/t/...all-android-roms-with-swap-partition.3901773/
The Automatic Wipe All will make the Tablet 100% Android with swap and install TWRP which is use to flash all the ROMs:
https://www.mediafire.com/folder/caibu8meh2qbd/Automatic_Wipe_All_and_Create_Android_with_Swap
Download the zip file and flash it with the recovery that is on the tablet now, do not use the TPtoolbox to flash.

HP_TOUCHPAD, how can I get the TWRP files onto the TouchPad if I can not access its drive from my computer? Even if I use the WebOS drive mode, I still cannot get in. Also, disk manager says that the TouchPad has a RAW file system.

Look at this guide, it has everything that you need and can do the job with just one click.
https://forum.xda-developers.com/t/hp-touchpad-novacom-repair-android.3960435/
The Novacom driver is use to load any uImage into the Tablet's memory, uImages are like Apps that provide ways to fix or boot the tablet, like a recovery TWRP can be loaded into memory to flash any files.

How do I use the Novacom Repair tool to install Android?

The guide provides all the details even videos:
I can not explain the same here what I already have done in the guide.
The Novacom Repair is a Linux OS with all the required drivers and files to fix any issues with the Tablet. There is nothing a user can do to brick the Tablet, everything is very easy to fix with just one click.
Flash the Wipe_All from the guide and it will do everything, even install TWRP which is the App that allows to flash any Android ROM.
After the Tablet has been setup using Wipe_All, it will boot into TWRP.
Then use this guide to Flash any Android version you want with all the optimization files and options.

I would like to keep WebOS as well, is that possible?
