[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] touchpad wont charge/stuck!!!

hello everybody!!!
about 2 months ago i modded my buddy's touchpad for him and everything worked fine. well he brought back the tp to me and saying its stuck and it wont work for some reason. also i am not able to charge with any usb cable it keeps saying
"to reliably charge, use the cable and power adapter that came with your device."
i just want to charge this thing up and remove classic nerd ics from it and simply make it stock web OS cause its become too laggy and glitchy for some reason and i dont know why. well to be honest i havent used it much this is feed back from my buddy.
i just need to get this back to web OS in a couple of hours cause he is a truck driver and needs it on the road. please let me know thanks

In WEBOS it will only charge with an original charger just so uou know..... in Android you can charge with most anything but anything less than 2amps and 5.5 volts is just gonna trickle charge
As far as the Android install it probably just needs an update and clean boot but if you took the time to tead you would find that WEBOS DOCTOR is used to wipe android off the Touchpad

So is the battery dead or are you able to turn it on? The TouchPad needs a certain amount of poswer to charge the device. Thats why the TouchPads original charger has such a big adapter. You chould probably get a slight charge with other chargers but it will take a long time to charge.
As far as android being buggy, I would suggest the same as cdzo72 and just reinstall it. And also like he said, the webOS Doctor will get rid of android. There are also apps in preware, I believe, that remove all traces of android after you uninstall it.

the battery is dead and it wont turn on im trying with orignal hp touchpad charger but there is no power...what to do next ? like its completely black there is no power at all not even a battery sign of charging or anything like that

I'm having the same problem as stated. My battery completely drained. When tried pluggin in it gave me the message "plug in original charger" which I have except for the cable. On the home button I had no chargin light. After a couple of hours I tried turning it on pressing power+home and I got the red battery, then immediately the plug in symbol, then the "plug original charger" message.
Then I decided to plug it to my laptop. The home charging light finally came on stating that it was charging. It's been a couple of hours and I was able to plug it back to the original charger on the wall and the home light continues to show that it is charging. Unfortunately, I've tried to turn it on and I still get the message. I'm going to let it sit for a while to see if it's just not charging fast enough to even power up. I am running CM9. Not planning on going back to WebOS anytime soon. If I get it working, I will let you know.
Oh, if you have the original wall adapter, you can unscrew the actual plug off the adapter by turning it counter clockwise. Then screw it back on. Supposedly that will fix something with the actual wall plug. I don't know if that's what caused mine to actually work again.

If you regularly charge it with a Touchstone charging stand, take it off, and plug it in through the outlet and the cable that came with it, and be sure to try charging in WebOS instead of Android.

[Q] HP Touchpad battery doesn't seem to charge. Is it dead?

I have a HP Touchpad that I just opened from its box, so its brand new running stock HP WebOS. The thing is, I bought the tp almost 15 months ago and never unboxed it until yesterday. When I put it up for charging, the dead battery symbol appears( rectangle with a red dash at the bottom and flash on top) and doesn't seem to charge.
Can anyone tell me if this means that my battery has died since it was unused for such a long time?
Or is there anything else that I can do to spring it back to life?
P.S I've tried almost every combination of buttons, e,g Power+Home, Power+Home+Vol Up etc.
Any suggestions on this will be extremely helpful. Thank you very much!

Just plug it in with the supplied USB and power connector for up to 4 hours. Do not use computer USB.

I have no idea if this will work, but you might try it:
http://www.slashreboot.com/journal/2012/8/18/an-odd-hp-touchpad-charging-problem.html
Here's another miscellaneous advice:
The round part of the charger, that the USB plugs into. That can twist open and closed to remove the part with the plugs. Make sure its fully tight. They can become loose, which prevents them from working.
Hold the power and home buttons down (not the volume +). press these together and hold them down for 30 seconds (actually shouldn't be that long, but it cant hurt)
If its still not working. Let it charge overnight and try again.

Thanks, I'll try that.

Perhaps not quite the same problem, but what I had fail on mine was the HP USB cable - The little contacts must have gotten dirty or something because the Touchpad just wouldn't charge unless I bent the connector in the socket a little.
Not too keen on that so I now use a different USB cable and it's fine.
I also agree with the above, use the dedicated charger supplied and not a USB port.

Battery 100% On, 80% Off

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?

Can't unbrick 32gb wifi touchpad

I'm stuck!
My touchpad was bumped off the wireless charger one night and the battery appeared to have died, and its never showed any lights, display, or signs of life since then. Tried multiple chargers and cables. I even replaced the battery which cost as much as another touchpad, disapppointingly no change, UGH
I found tpdebrick v005 and some instructions. Ran it on ubuntu 16, and got this error: https://imgur.com/a/D9AkT1c

I grabbed the typescript logs if those are useful to anyone ;-;

WOW
I was reading through this thread https://forum.xda-developers.com/showthread.php?t=2126307&page=14
I noticed @jaycee147 saying something about seeing the same error I have and using heat to get past it......IT WORKED!!!
I ran tpdebrick with the autoreset option, then kept applying 30 seconds of heat from my hair dryer, then retrying whenever any step failed. Each new attempt gave new behavior until it magically started booting itself!
When I shut it down to fully reattach the display and seal it up, it refused to power on and show any signs of life again....
Repeating the same process of heating and tpdebrick brought it back again.
I will leave it on the charger until it's full and for the sake of science try to reboot it again and post my results

it rebooted and survived
it was able to shut down for a few seconds, and power back on
but powering it off one last time and back on again its acting like its totally dead again. back at it again with the hairdryer and if I get it working again I assume I'll NEVER be able to let it shut off again?

Ambient temperature ( room temperature ) is very important when charging any Lithium ion battery. ( Warmer charges best than cold )
It is extremely important to never let the battery drain to zero capacity as it can go dormant and difficult to wake up.
The battery needs to be on charger for a full day, if the battery does not hold the charge check the " true capacity remaining"

I am way ahead of ya!
When I first got the tablet to boot up after reviving it, I let the battery charge to 100% for a few hours on the original touchpad charger
Once I shut it down and tried turning it back on, it refused.
Not sure what the battery charge has to do with this anymore? When I tore apart my old battery, the cells were still at 3.7 volts, so something else must have occured

The only way to really know the ( TRUE ) capacity of the battery is by doing the following:
open a command prompt or terminal on a PC with the novacom driver and enter:
novacom -t open tty://
then
battery status
To know all the details of the battery you can read this thread:
https://forum.xda-developers.com/showpost.php?p=80993173&postcount=17
The battery can be 100% charge but at what capacity?

I keep getting "unable to find device" after getting novacom to work : (
I searched these threads and can't find any solutions for this situation with novacom, supposedly there's supposed to be some sort of life from the tablet (buttons or display lighting up) for novacom to work?
I'm on ubuntu 12 32-bit using the same 32bit novacom drivers

For the novacom connection to work the Tablet needs to display the ( big white USB symbol )
select webOS Recovery from the moboot 0.3.8 menu.
When the USB symbol is shown then connect the tablet to PC using usb cable.
If the tablet is running low in memory, place the tablet on the wireless charger and use the usb cable to connect to PC at same time.
On this thread you can find a linux OS with the nocacom driver install, it can be boot from any PC or also be use in a virtual machine.

To automatically get into recovery mode with the tablet off.
Press and hold at the same time:
Power and volume down key ( closer to power )
The Tablet will boot into Recovery mode.

For the novacom connection to work the Tablet needs to display the ( big white USB symbol )
select webOS Recovery from the moboot 0.3.8 menu.
When the USB symbol is shown then connect the tablet to PC using usb cable.

I greatly appreciate you trying to help, but I've mentioned a few times now that I have no such signs of life on the tablet, so I don't know how this helps at all : /
Thanks

Very contradicting information, on your #6 post the tablet did boot. You also tried heating the tablet with an air dryer and that made it to charge and also boot. If the Tablet did boot, then is not brick.
I will help, but can only provide proper guidance if the correct information is provided.

Correct! As I said in post #6, I heated the tablet up and I was able to get tpdebrick to run and the tablet booted up as if nothing wrong happened.
I charged the battery to 100%, then tested a reboot, which it survived.
I then tested a shutdown and power on, and it survived.
I finally tried shutting it down one last time, and at this point it refused to power on again, no show of any LEDs or display with any charger or cable.
I'm not contradicting, what I'm saying is after I got it to boot with heat and tpdebrick, I shut the tablet down, and now it's refusing to do anything again (no leds, no display with any charger)
I hope that clears it up

The battery can show 100% charged, but the most important is the capacity.
If the capacity is very low, it will loose charge very quickly and go dormant.
I then tested a shutdown and power on, and it survived.
Then the Tablet is not brick, all components are working. It seems the issue is a battery with very low capacity.
I finally tried shutting it down one last time, and at this point it refused to power on again, no show of any LEDs or display with any charger or cable.
Was the Tablet connected to a charger or place on the wireless charger all the time while on and off?

Battery is depleted.
I hope that clears it up

Try to revived it as before, only with some heat. I do not know your ambient temperature, is better if is over 80F to take some charge. It will take longer or not work in cold.
Boot tablet while place on the wireless charger at all time, do not removed it from the charger.

Hmmmm...
When I had it charging, it started at 15%, and after a few hours it went to 100% . I see what you're saying re. capacity, wish I had checked that while it was working.
I did not have it on a charger when I tested my reboots / shutdowns : ( I had too much faith in the battery's charge and being able to bring it back if I goofed.
I've been trying to heat it up for a few hours this morning and run tpdebrick and I still get the fuse error, but it progresses, writes stuff, and aborts when waiting too long for fastboot.
I guess I'll keep trying the heat with tpdebrick while having it also on the wireless charger until it works

It takes more than a couple of hours to charge at full capacity. It all depends on the capacity available or the battery health. If is less, it will take less time to charge.

The battery capacity must be very low, that is why it turned off after a couple of reboots or until the battery got empty.

If the Tablet already rebooted, is not brick. It needs to be charge.

Read this link very carefully, this is the real TRUTH of the tpdebrick process.
https://webos-internals.org/wiki/Last_Resort_Emergency_BootLoader_Recovery
If bootie on the flash disk has been damaged or corrupted in such a way that booting into recovery mode is not possible, the Pre is still not "bricked" as the OMAP3430 processor in the Pre provides for a mechanism to boot code from its USB interface.
The HP Touchpad uses the same OMAP3430 processor as the Pre and the same process to re-flash the bootie ( BIOS what is call on PC ) can be perform.
That is the process that tpdebrick is doing, reflashing the bootie.
Your tablet already booted, the bootie works.

I'm sorry, you're confusing me more.
How is it possible that when I put it on the OEM charger for a few hours and waited until it "reported" 100% that it still didn't have enough capacity to survive two shut-downs within a minute? The tablet wasn't off a charger for more than a few minutes total before it died.
The battery is brand new and still measures 3.7v at the cell. I have a hard time believing this is still the battery being a problem, but you certainly have more experience.
Are you saying I should follow the instructions on the link to recover, instead of tpdebrick?
Or are you saying my tablet is "working" right now and my battery is still too low? If this is the case shouldn't it show that it's charging? Shouldn't tpdebrick NOT fail at the fuse blown step in this case?
Thank you

I will try to explain it in a very generic and simple way.

Capacity or (battery health) = The amount of electricity it can be store in the active cells. (good cells ), dead cells or inactive does not store electricity.
The system reports 100% charge, but does not report the capacity. The only way to know is by entering the command using the novacom as mentioned before.
If the capacity is only 10% of active cells, it will show charge 100%, but it will lose charge very quickly.
This applies to all battery's.
The battery is brand new and still measures 3.7v at the cell. I have a hard time believing this is still the battery being a problem, but you certainly have more experience.
A battery can be new, but if stored improperly for many years can go bad.
The only way to know the battery health ( Capacity ) is by getting the reading of the A6 controller.
Are you saying I should follow the instructions on the link to recover, instead of tpdebrick?
The link I provided explains technically the reason a WebOS device may not boot.
And provides on how to re-flash the bootie and that is what the tpdebrick does.
tpdebrick is use to reflash the bootie to make the tablet to boot. It has nothing to do with the battery.
If a battery does not have enough electricity to power the internal components, the tablet can not boot.
If the bootie is damage, then it will not boot even if it has a brand new battery and full charge, then the tpdebrick needs to be done.
Or are you saying my tablet is "working" right now and my battery is still too low? If this is the case shouldn't it show that it's charging? Shouldn't tpdebrick NOT fail at the fuse blown step in this case?
Your tablet already booted, it shows all components were working, is not brick, by the way the tablet is un-brickable.
The tablet should show the LED light moving from side to side when connected to a charger. If not then try to warm it up and to intermittent charging, ON for 1 minute, OFF for 10 seconds. It can be done with the wireless charger. Place it on for one minute then remove it for 10 seconds. Do it many times, from time to time until it shows the LED light, then a low battery comes up and finally it will boot. Never remove it from the wireless charger.
Thank you

You are welcome, hopefully it resuscitates again !

Ok that all makes sense : )
I've been trying the intermittent charging w/ the wireless and heating it for the past hour and a half-ish, it's still not shown any signs of life. Should I keep going?

Oh, I have a kill-a-watt that tells me the power draw of anything plugged into it
Using the oem hp barrel charger, and the wireless pad, when plugging just the barrel into the socket, 0 amps. Plugging the wireless pad in, still 0 amps. Place touchpad on wireless charger, I see about 0.01-0.02 amps being drawn. The power draw never changes or fluctuates no matter how long it sits on the wireless pad
I don't see any amps pulled when trying to charge via microusb

The wireless charger works better on charging a dead battery than the usb connection.
Make sure the ambient room temperature is over 80 F, or you can cover it while is been charge. You do this when you are home and supervising.
It can take time for the light to start blinking, some times like a week. Leave it on the charger and sometimes just pick it up and place it again, just when you are checking on it.
Leave it there for a couple of days.
