Reboots after I remove the batter

What the heck is going on?
I'm pretty sure this has nothing to do with the ROM, because it did this with the factory ROM, Manila 2d and now WM6.5.
I turned the phone off, unplugged it, removed the battery. I put the battery back in, replace the cover and press the power button. Nothing happens. I plug the phone back in to the wall charger and put power, it turns on....for about 3 seconds then reboots and it would seem that it will do this for as long as I let it go. If I unplug the phone while this is going on, it will die.
The last time this happened, it took it about a day and a half to sort itself out. It almost seems like its a battery issue.
Any thoughts or ideas?

UPDATE!
I took the sim card out of the phone for a few seconds and the phone seems to be working now.... But its been up and running for about 20 minute now with no sings of acting up.

mine started doing that today. went to use the camera and it reset then when it came back on it said battery was drained(this happened around 1pm and i always get a full day out of battery) and reset. have it on a charge right now but will not turn on. took out battery and put it back in with no luck. i will try to fully charge battery and take out sim. if all else fails i will try to hard reset. thanks

kaiser won't turn on

tried to charge the pda all night the light stayed orange and never turned green indicating full charge. tried hard reset and when it goes in to prepare rom it shuts off like dead battery. when i plug in the pda to charge battery and then turn on the phone it freezes on splash screen. if i turn on phone then plug in to charge it acts like i havn't pluged in charger. is it the pda or battery?

I am not 100% sure on this, but to me it sounds like the battery.. and that is a MUICH cheaper option to test out... unfortunatly you ahveto wait for shippng typicalyl unless you have a friend who has the same phone.. I got 2 backups and a stand alone charger now... The other option could be your USB port... I have not heard this specific problem with them.... but I am a PC tech and have seen very simmilar problems with laptops... Usually the first think to for is the power port... Just like out phone, if the device is not on a flat surface and such when it is plugging it, it tweaks the port and it eventualyl breaks... on laptops it is not uncommon that when plugged in, the LEF wil light up saying it is getting power to charge, but it enver charges the battery, and even sometimes can;t power up the full system.. .It sort of sounds like this is what you phone is doing as well.. .If that is the problem the stand alone charger would work (my son broke off his usb all together and now syncs via bluetooth and jsut changes batteries.. he has 3 himself as well) If you search online, you can usualyl find a kti with a battery or 2 and a charger/dockign station for under $20US total. Good luck!

tried bootloader and installed official att rom and never shut off. when it was finished with install same issues appeared. help

For anyone facing this issue I would not recommend wasting money on a new battery as this issue has been around with few users since the Kaiser "Tilt" first came out and I've never seen ANY reports that a new battery fixes this. People have bought new batteries, fully charged their battery from a docking station, tried their friends fully charged battery all with the same result. I had this power down issue a Looong time ago my first week in with the Kaiser and managed a fix and am using the same battery now. Although it seems the battery is not being fully charged it's important to leave it charging until you'd assume it's fully charged and get into bootloader mode and flash an official htc Tytn 2 rom. It should flash completely, and the fact that it does not die immediately as on normal boot indicates it is not the battery but the rom. It did take me the whole afternoon of Flashing, recharging and repeating before it finally kicked in. Also, from reading older posts, it seems most if not all users like myself fixed this by flashing the older official htc wm 6.0; worth a shot at least.

Yup, that is what I had to today (I hard reset, actually), with barely enough battery life to do this.
Then the bloody unit came up and was charging - amazing, really!
(Was using the official HTC 6.1 upgraded WindowsMobile OS)

here is my 2 cents....
I owned five Tilts, replaced four of them with warranty issues ... so i have faced this dilemma on at least two of them.
First see if the USB tongue is loose. To do this try to gently tap it with the stylus. If the tongue inside the USB port is loose then you will be facing rebooting and other issues and troubles in the future. The USB tongue gets used and jerked every time you connect your device to your PC or wired headset. If you are still under warranty and the USB connector tongue is loose I recommend returning the phone ( if you still can) and getting a replacement. There is no easy fix for a loose USB connection tongue as i have taken one apart and it is very difficult to repair or replace and very easy to mess it up further.
So, my advice to all Kaiser owners... be careful when plugging and unplugging your phones through the USB. Do it gently as the connectors are very fragile.
For those that have the above issues, I recommend using a separate battery charger tray, avoid plugging the USB as much as you can, and if you must, then administer extra care. The rebooting will stop if you plug the USB cable to the device and move it up and down a hair then holding steady. And most likely you will not get a full charge or even a partial charge. The biggest culprit to this problem is car chargers, and second, is inserting the stylus by mistake (when it is dark and hard to see) in the USB port instead of the Reset hole by accident.

[Q] Stock Nook: Battery too low to power ON.

Ok so this nook was bought brand new in December 2010 For my mother In-law. She hasn't used it much. So I asked if I could put Android on it? She said sure cause she hasn't used it at all. As a matter of fact the NC was totally dead when she gave it to me. So I get back to my house and put it on the stock charger. I let it charge for 2 hours. I picked it up and turn it on and all I see is this message: Battery too low to power ON. I did a search and turned up similar problems but the nc where all rooted. I'm wondering if other people have had this same problem? And what they did to solve this as it is more then likely an easy fix. A. Take it back to the store and exchange it. Or. B. Send it off for repairs. C. Someone On XDA has the answer.
Also I've done some trouble shooting like trying to reset it. Also I've used 3 Other chargers and its still not charging or turning on.
Edit: It turns on it just stays at the screen with a red battery displaying the message in the title. Also after charging for a while the screen kind of lites up like its going to turn on but only goes black after that and then comes back to the same red battery screen.

what are you charging from? are you using the stock nook cable and plug?

Yes. And charging it from the wall outlet. Did that with the stock charger. my charger from my HD2 and also tried with the charger from my vibrant. All have the same affect. It has the red battery and the messege below and it also has been a total of 6 hours of charging 2 hours each with the all the chargers.

That stinks. You may have to contact B&N for it. If your using the stock and other chargers then it must be a battery failure.

Yeah seems to me thats what it must be I'll post back what I find out.

When that message is displayed, try holding the power button for 30+ seconds and then turning it back on.
That has worked for me the couple of times it seemed stuck on that screen.

If you're using other chargers, it's possible that you've damages the usb port. The NC uses a non standard usb port, which has two stages. The first stage is standard 5 pin uusb communication, the second stage is non-standard 12 pin charging...

Non-Standard chargers...
As far as I can tell it works fine with any microusb cord.
Their charger cables break...(bend and break) very easy. I have gone through 2.
The upside is that their charger provides power far faster than the normal microusb cords.
At this point...I'm charging mine almost exclusively from my stock evo cord.
If you don't turn off the screen when charging...it may not have enough power coming in to actually build a charge without their cable.

I never used another charger besides the stock charger that came with the NC. Up until this happened all that was ever used was the stock cable for charging. I only used another charging cable once I ran into these problems cause I figured the cable was damaged. Its happened to me before with other devices. But the same results happen with every cord I use. When I plug it in it lights up and shows the red battery screen. So that tells me that the cord or USB port couldn't be the problem. Cause its clearly getting power its just not charging.

No. They sell it without one...the 8GB internal storage is enough for looooottts of books. The microsd was just a nice + for people with lots and lots of music.

I had this issue as well, but I found a fix!
No matter what I did or how long I let it charge, it would always have that red low battery icon.
What I ended up doing to fix it was opening up the back of the unit and disconnecting the battery cable from the unit. I then plugged it directly into the wall without the battery connected to see if it would boot, though I don't know if that was necessary, I don't even remember if it booted that way or not.. I think it did not.
Anyway I unplugged the power cable again, reconnected the battery, then plugged in the power cable and tried to boot and it booted up perfectly after that. The battery icon indicated 13% charge, but it quickly charged back up just fine.
FYI I left the unit in the car overnight right before this happened, and it was pretty chilly that night, 10-20 degreed Fahrenheit. I suspect that caused the issue for some reason, so I've been sure not to do so since.
P.S. I had to do a fair amount of googling around before I found good instructions on taking apart the NC. I think I had to take off the 2 screws under the SD card slot and use a butter knife to just pry the back off. It's just held in with clips and you can't tell it was opened except for the little stickers over the screw holes.

Thanks for the feed back. I'm wondering by un-pluging the battery from the nook if it resets it. Kind of like if a phone freezes or if your computer freezes and you pull the battery. Seems like a plan. Not sure if this is what I'll do as I'm sure its still under warranty. If it comes back and its not covered or B & N wont replace it I guess thats my only hope.

im having the same problem as well it was off for a while and now its at the red batter screen. i guess ill try and take it apart?

If your not worried about voiding the warranty then sure I guess its worth a shot.

So I got it fixed right. All it was was a faulty cable lol!

I had this problem too, but I'm not sure "faulty" is the right word for the cable.
My friend borrowed my nook and returned it with a dead battery (Thanks asshole). So I plugged it into my computer at work and just got the always-on low battery message. After 45 minutes I took it to my car so I wouldn't forget it. I plugged it into my USB charger in the car using a different cable. Two hours later, same state.
When I got home I pugged it into the Nook wall charger with yet another cable (not the nook's original) and got the same thing. I searched here to see if I could figure out what was going on and decided to try the original cable with the wall plug. literally two seconds after plugging it in it started booting into Froyo.
I'm sure I didn't have four "faulty" cables. I think those that are saying you should be using the original are correct. The others worked fine when the battery wasn't empty, but mine only responded to the original once it got to the point of the unending low-battery message.

Original charger / cable required with totally empty battery
Same here. With battery completely empty and non standard cable,stuck at red battery sign forever. With orginal cable, boots fine and charges.

solution I found
Have CM7 installed on SDCard, got the battery icon, even with the unit plugged into the charger with oem equipment. Held the power button 'til the unit turned off completely, removed the sdcard, rebooted. Nook booted into stock fine, turned off, re-inserted sdcard and rebooted. All is well.

[Q] Milestone dead, no power

I was flashing the latest iceandfire rom, did a reboot and the Moto logo came up but it never booted. Holding the power button didn't do anything so I pulled the battery. Now there's nothing. The LCD never comes on, can't get into recovery or boot loader. No charging light, nothing...
This has happened to me before and I had it sent back to Motorola. They were able to reflash the phone, I know because I got the same phone back. How they managed to flash it without it powering up is a mystery to me but I know it's possible. Has anyone managed to do this? I would send it back to Moto again but this time, it's out of warranty.

Did you charge with USB cable? I had this once where USB charge completely failed. I just had to use my car charger and that fired the phone back up.

I had this happen to me also...use a Motorola brand (no copies) wall or car charger and leave it plugged in. My MS does this when it gets really close to 0% charged...
Sent from my Milestone using XDA Premium App

I don't think the battery is dead, it was full and I was plugged in while I did the flash. The charge light flicks on and then goes out when I plug any cable in but I'll give it a shot with the moto charger when I get home.

yeah, the phone's bricked... using all factory chargers and cables, it still doesn't power up.

I give up... tried all night to get it to the boot loader. I guess I'll be selling this thing for parts and use this iphone4 I got through Fido retentions until I figure out my next phone

Before you throw it away:
Try getting another (full) battery or another Milestone (to charge it), or something like this: (I am not allowed to post a link, so google: UNIVERSAL BATTERY CHARGER, select the first video in results).... charge it, then re-insert the battery and try to power on device holding d-pad UP + pressing power button.... it should bring you to bootloader mode, then connect usb cable and use RSDLITE to flash the appropriate SBF for your device and region..... and for ROMS (SBFs) google: milestone sbf, select the first link in results.... hope it helped... cheers....

Does the "McGiver" jumpstart thing using a usb cable with the device end cut and keeping some of the wires connected to the device in the battery compartment work on Milestone? I know a friend that could "unbrick" his Defy using this method....

Do you have a link? I remember reading this somewhere as well. It's worth a shot, not like the thing can be more dead. I still don't think it's the battery tho, it was full when I performed the flash.

Nevermind.... I found it, it didn't work... lol... oh well..

Sometimes the batteries memory will glitch

Not the battery, it was full when I did the flash and I tried jumping the battery terminals with a USB cable. It was good while it lasted but I already picked up a BNIB Captivate for $300 off Craigslist.
Anyone know what a Milestone sold for parts would be worth? It's about a year old and I would say the condition is 8.5-9.0/10

Before you sell it, take out the battery, SIM card and memory card, then leave it for AT LEAST 5 days. Then try again.
I have a similar problem with my milestone, at first I thought it was dead, then after a week I tried again (just on the off chance) and was able to get into the bootloader menu and reflash it.
There is something inside the Milestone that holds charge for several days, and pulling the battery for at least 5 days seems to clear it. This has happened 3 times with mine, and each time I was able to get it started again.
This may not work for you, it depends on exactly whats wrong with yours, but its worth a try.

there is a post from a guy looking for the motherboard... u might want to see that... sorry for ur device

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.
Sent from my SGH-I777 using xda app-developers app

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:

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 --- )

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.

How likely will this CATCH FIRE???

Hi Guys,
I have owned an HP Touchpad for around 7 years, and totally loved it. Sadly I've not used it in about 6x months to a year solid. Now it wont turn on at all, Ive tried charging via the official wall charger, via a mobile charger, via PC USB (trickle charge) and tried all the various key combo's, nothing, totally dead. This happened once before, and took some effort to get back to life, but it did and was fine for many months after.
I asked my mate, and he said just throw it away... If I've let it drain beyond the safety level, then there is a chance it could go BANG... I've read various other threads/forums, other than here also.... and although some have attempted to revive the battery. Lots warned about doing it outside, as there is a risk it could go bang and catch fire!!!!
So, whats the verdict guy?? Have any of you had a Touchpad that is beyond booting, no display on the screen at all, no symbols and even the Home button isn't even lighting up or flashing. There is no life in it what so ever...
Dangerously, before reading more about it... I had left the Touchpad on original charger for best part of a week, about 4 or 5 days continually charging. The wall charger not even warm, yet if I use it on my Android phones, it works just fine.
I've left it on PC USB charge for over day, and still nowt....
Sounds like its dead, anyone else got lucky from this point? Would charging it any further risk of blowing, or are their surge protection in the Touchpads design to prevent this???
Are their any other Android Tablets that allow dual booting of say Linux as well as Android....?
Cheers, Lister

There has been success when TP owners have connected the TP to a low power phone charger and left it going overnight/all day. This 'gently' charges the system sneaking past any system blocks and allows the thing to charge to be able to boot. Once booted stick the proper charger on it.

Hi MikeN68,
Thanks for replying back, much appreciated... Do you have a TP too?? Has this happened to you...?
It happened to me about a year ago, but I was able to boot the thing back into life after a long charge. But all the time it wasnt booting back then, I still had a flashing light on the Home button. However this time I get no light on the button at all or any symbols on the screen.
Ive had the TP on the original charger since Sat / Sun through to like Wednesday... and nowt!!! Then I've had it on a low charger for a few hours, and on a PC USB socket for a couple of days... and tried a couple of USB cables and nowt there!!!
May give it the low volt phone charger again, and hope.... Really hoping I can make it live again, as looking for a replacement cheap Tablet that can support many roms and there really isn't anything else out there...
Thanks again...

Hmm. OK, have a look over at the webosnations forum I've included the URL but not sure if that will get deleted or not, so "revived-touchpad-my-story-full-instructions" is the title of the post in the Touchpad forum.

Good luck and no, I've been fortunate enough that my TP's have behaved themselves.

I've never heard of a TouchPad battery blowing up. However, as with any Lithium Ion battery, there is always the risk. I've read of folks leaving their TP plugged in for months before it finally started charging again. As you can see by the other posts, their are as many ideas as there are people to post them. One never knows which will be the magic trick. But unless you can get some life back into it, none of the suggested tricks will work. Good luck,
NT
