Yesterday I turned my Prime off and it refused to turn back on. I was told this was the sleep of death, so I reset it with a pin. When I turned it back on the battery indicator was at 0% with a '?' next to it. The tablet still works, but the power lead isn't recognised when I plug it straight in to the tablet. I'm currently running on dock and all is ok. When I use it without the dock it seems to go in to the sleep of death (perhaps because it thinks the battery is 0 it simply won't attempt to wake up). The weird thing is, it has been running off dock power for about 4 hours, and the dock still says 98% with the main battery at 0%. If I unplug the dock the tablet continues to work suggesting the main battery is running, so I'm no clearer as to whether this is a software or hardware(sensor) issue.
Anyone seen this before and suggest a remedy? I've done a factory reset to no avail.

Hahaha. Easier said than done. I've been offered a refund, but there is no stock to exchange it with. I was kind of hoping this was a software issue.
just fprecalibrate theattery. it'll reset the values or something. not sure if it there's a native way to do it stock. you may need an app from marketplace. or do a factory reset to put it back to the way it was when you got it out the box. that "should" clear it.
I just took a screenshot of their website just in case they try to remove "battery" from the specs list.

Already did two factory resets. The weird thing is it still runs, but refuses to turn on after turning off, unless reset is hit.

TF201 / XDA premium
So today i got the dock for my TF201.
At first, the tablet wouldn't recognize the dock at all. So i let it charge a bit. Then it recognized the dock (notification tray icon saying that dock is connected), but it showed as 0% battery (weird), then it jumped up to 48%, and the cursor+keyboard worked fine.
I let it charge the rest of the way (both tablet and dock at 100%), and unplugged it and went to the other room. (not on AC power) Once again, the dock wasn't even recognized. So i rebooted, and now it was recognized again, but again reporting 0% battery, and neither the keyboard nor touchpad were responding. So I let it sit again (not on AC), and now it says dock battery is at 100%, although the touchpad, and keyboard still do not work.
Is my dock just defective, or is there something I should know?
(stock ICS, not-rooted)
if wrong section, i am sorry, i'm new here.
Check the connection to the dock...it is a tight fit and its easy to not push it all the way in.....look at the release mechanism it should be set all the way to the right.

I too have had some intermittent issues with the dock. Mine usually occur after it has been asleep for a period of time. I will have to pull it apart up to two or three times to get it to work again. Mine is always recognized but the touchpad and keyboard will not respond. I am thinking about sending it back to Amazon for a new one. I am trying to deal with it as long as I can though since they do not have any in stock at the moment.

yea, now that i have done a full 8 hour charge (RTM actually worked for once ) it seems to be working fine, but that sounds like exactly what i was having.
Now the battery seems a bit off, but that is probably just my imagination at this point.
seems to be working 100% fine now. Strange, kinda just let it charge, and now it works...
Hey, I bought my tf201 yesterday (did the ics upgrade etc) and I noticed exact the same problem when I start testing the dock station. I charged both to 100% and the tab didn't recognize it... Sometimes it showed 0% than suddenly 98%... Sometimes key's did work like turning off wifi, BT. But the letters didn't. touchpad = just dead. Also the dock wasn't recognized when you look in settings > "about phone". I brought it back to the shop, they tried the dock from the one that's in the showroom. And it didn't work either, seems like there's a connection problem in the tab itself. They couldn't give me a new one because all the others were already ordered. And I need to wait 3 weeks for the nex batch so they gave back my money.
This really sucks... The tab on it's own was working well and pretty amazing performance.
Hey I seem to be having some trouble with my Nook Tablet. I've got the 16gb version, bought it within the first month or so of the tablets getting released. It's been running fine, i have it rooted, ran cm7 for the longest time on it, switched to cm10.1 more than a few months ago and everything was pretty great, then crap started going downhill.
I noticed that when my battery would get down between 20-30% it would just shut down. The low battery screen would come on for a split second before the "tablet is shutting down" screen would pop up in front of that and it would shut down.
Now, since then it's been happening more and more. When it's at anything lower than 96ish% it'll happen. But it's got some weird symptoms.
- The screen freaks out. Like there's 100 fingers on it pushing a ton of crap at once, when I'm not touching it at all. it's sensing a bunch of false touches that usually ends on the Google Now screen before getting the same old low battery, then tablet shutting down notifications.
- It only happens when it's running on the battery. It's never ever happened while it's plugged in.
- It only seems to happen when the wifi is on. If the wifi is off and i'm at home just reading a book or something, it'll drain all the way down to 15 or whatever before telling me the battery is low, I plug it in, all is fine. If the wifi is turned on the freak out happens.
- If it starts freaking out and I plug it in while it's happening, 1 of 2 things, It either completely stops and everything works fine, or it just turns off dead right there, not shutting down, just turning off.
- I HAVE had it drain pretty low (around 23ish) with the wifi on, but it did do the same freak out thing once it got there. It just seems to be so random when it happens, any time the battery is between 15 and 96%.
- If I turn it back on after a freak out without plugging it in first, it will restart fine, then last about a minute or 2, freak out again and shut off. If I turn it on again after that it'll do the exact same thing. And if i turn it on again after that it'll get to the CM10 boot screen, just about to where it's going to go to the lock screen, then boom, makes the beedoop battery sound and shuts off without ever actually showing the lock screen. THAT happens everytime just like that. If I plug it in first and then turn it on, it runs fine.
I've tried factory reset and reinstalling and all that stuff, nothing seems to be working. I even started from scratch not letting google or titanium backup restore my apps, completely formatted and wiped the sd card when reinstalling, nothing seems to be fixing it.
Basically this thing is useless without being plugged in. Ive even lost a 32gb sd card because of it's constant just turning off screwing it up (i'm guessing) since it's not being properly dismounted or whatever before being shut off. That card cant seem to read/write anymore. I now have a 16gb in there I'm hoping wont get screwed up because of the same thing (although I'm sure it will eventually if this isnt fixed)
Is this a battery issue? A hardware issue? User Issue? Can anyone help? I can provide any information you might need.
I've been searching for months trying to find an answer, but the symptoms are so weird I cant find anyone having the same problem as me..
Also, my fiancee also has the same Nook tablet, bought them the same day, rooted and hacked them the same way that day, and put CM10.1 on both of ours the same way the same day, hers is fine, mine is acting a fool. (I also use mine about 1000x more than her though, I use mine for EVERYTHING, EVERYDAY, she reads Sandra Brown books and watches YouTube movies once every month and a half)
Help? =[
the finger touch thing at random on your screen without touching it is your charger cable , its a crap cable , i had this happen to me too , B&N will swap the cable and charger for free, i highly suggest you do that and get a new one swapped , mine still has issues , when its plugged in and charging , i sometimes cant use the touch screen , its the charger , they are like 1 in 3 garbage and cheaply made ,
take it to the store they will swap the charger for free, if they hassle you ***** up a storm , they are supposed to just swap them , its well known fact the cables are cheap garbage and not easy to get new ones that are not garbage, i use micro usb's it takes longer to charge but i get quality cables from amazon cheap as piss 2.49$ if you want the link ill find it , again takes longer to charge , but i no longer have touch screen issues and can use tablet while its charging ill re read the rest of your post and make an edit if i can help on anything else
spyder
how long are you charging it for at any one time ? i do believe if my memory serves me right , theres a problem with the battery level on both cm 10 and 7 , seven is way worse, the battery level is not reported correctly , its being worked on by better minds than ours , im sure one of em will chip in here shortly ,
if i were you you have cynoboot installed to emmc ? i would turn the thing off completly , and charge the **** out of it , with a good cable , id use your girls cable it sounds like she got a good cable. like leave it over night charging on hers while you sleep , then in the morning boot it check the batt level in cynoboot and then in cm10.1 , im keeping mine juiced up , last time it died it ended in a boot loop that i had to unplug the battery to fix , most people dont want to crack a case even though its easy peasy ,
again , try her charger , if your powered up check how long it takes to charge fully it should be 6-8 hours on the nook 2.1 amp factory charger , i think you need a new charger though , i would try to swap cables until i found a good one , then look at ipad travel charger they are 30$ , but they output 2.1 amp and apple crap is quality which is why its 30$ , or look for a samsung galaxy tab charger USB output 2.1 amp ,
Ahhhh.. see. The battery level being reported wrong makes sense for why it happens so randomly. Another interesting thing you said was it should take 6-8 hours to charge with the stock charger, mine was reporting 100% battery after 2.5 - 3 hours charge time. This could be the problem.
I did what you said, let it charge overnight, and it did the same thing, but, not until it got down to 32%. Which is better than 82% shutdown.
When I get home tonight ill plug it in immediately and not touch it until tomorrow morning, well see what happens. Thanks for the response.

I may have figured this out. I switched my rom to aokp 4.2.2 and then flashed the showtime kernel, set cpu tuner to no more than 999mhz and all seems to be running fine. Bbs says 14hrs on battery, deep sleep for 9 of them, and I'm at 69% battery now. (Bbs started collecting at 91% for some reason instead of 100%)
I flashed the rom yesterday around 6pm, let the battery go all the way down to the first time it randomly died, then just charged it back to 100% and I've had it off the charger since then, 14 hours now according to bbs. Ill report back if it freaks out or something later.
Edit: turns out this didn't work.

Just did it =[ freakedout and shutdown at 77% battery, then got stuck in a bootloop.
It ran fine yesterday, I was watching podcasts on it no problem. Charged it last night and now today it seems unusable without being plugged in.
Does anyone have any other help they can offer?

I might have a solution for the battery problem. Do you have any microUSB chargers lying around? maybe for an old cellphone? If you do, use that to charge your Nook Tablet. It works, but it's slow, takes 8-9 hours for a full charge (5% to 100%) @ 500mA current. My old Motorola flip phone's charger supplies 5V @ 550mA. I'm pretty sure you have one of those lying around in the attic or garage. Anyways, let the NT charge to 100% using a microUSB charger (not the Nook Tablet's stock one, the cable is faulty and I am sure of it).
Once it's charged to 100%, go on YouTube and watch a few videos. If the battery goes down steadily, that's good. If it goes from 100% to 80% or less suddenly, there might be a problem with the battery calibration or the battery's going dead.
I bought a Nook Color off eBay that the seller listed as broken, except it wasn't. The battery was simply dead beyond the capability of the Nook's stock charger to revive it. I used the old Motorola charger. It took 10+ hours, but finally my Nook Color booted up, although with 18% battery life only. No matter what, it would stay at 18% until it shutdown without a warning. The solution to this was to delete a file called max####.bin in the /rom partition, then reboot.
Steps to recalibrate the battery (ONLY try this method if you're sure the battery needs to be calibrated):
Open the terminal (once you are 100% charged. You'll know this if the power adapter isn't warm anymore)
Type in "su", allow root access for once
Type in "cd /rom"
Type in "ls" (that's a lowercase L and S)
Type in "rm max#####.bin" (where ### are the numbers there)
Type in "exit"
Type in "exit" again
Hold down the power button and reboot. Once it reboots, it might show question marks on the battery meter before going away shortly. Hopefully, your battery will be successfully recalibrated.
Hope that helps.
Thanks a lot for the reply. I definitely have a charger lying around so ill try this tonight when I get home.

Just got done testing it out. I charged it for about 16 hours, pulled it off and powered it up, my battery status said charged, then 100, 99 etc. Once it got down to 87 it freaked and died.
The battery did drop way fast though. Like 100 to 87 in under 15 mins. Not instantly though.
If you search "nexus 7 phantom touch" on youtube, you'll see exactly what my nook is doing, only difference being the nook dies after about 10-15 seconds of the screen freaking out. And it ONLY happens when not plugged in.
If my battery calibration is off, would that mean maybe it could actually be around 15-20%, even though its reported as 100%, and not letting it charge passed that? Or is my understanding a bit off?

Right. My Nook Color was showing 18% charge no matter how charged or discharged it was (until I deleted the max#####.bin file).
Try what I said, delete the max#####.bin file and reboot. That will recalibrate your battery. If after that it still shows the battery draining way too fast, that means your battery is going dead.
Ok, so I reset the battery stats and now I'm seeing this.. this doesn't seem right at all..
I let it hang out for a while and it did the usual freakout/shutdown when bbs said it was at -22%, android showed 69%.
I think ordering a replacement battery or finally just getting a nexus 7 is the fix at this point?

Or actually, you might find "for parts" Nook Tablets on eBay for <$30. I would use the battery in there instead of buying a cheap chinese made battery (which are always of garbage quality, not to mention dangerous). You could also use a Nook Color battery in there, but you'll trade off 3 hours of usage time. Nook Color batteries on eBay sell for $7 used, but genuine.
Before you buy anything, try doing a complete wipe and reflash of CM10. Boot to CWM > wipe battery stats, wipe data/factory reset, wipe cache, wipe dalvik cache; advanced > wipe system partition; go back > flash CM10, flash gapps, flash CWM (if not already installed).

Awesome, thanks for all your help man. One more thing, I'm running CWM recovery v. 6.0.2.7, there's no wipe battery stats option in advance (or anywhere else I can see). Is it hidden somewhere I'm not looking or not in this version? Is there a newer version I can flash I overlooked?
Btw, http://www.newpower99.com/Barnes_No...cement_Kit_p/barnes and noble nook tablet.htm this was the battery I was looking at for $40, but the used nook from ebay seems like a better idea. (Cheaper too, which I like)

The CWM I used was a bootable microSD one. It had the option to wipe battery stats. At best, it will recalibrate your battery, nothing else.
I followed Ray Waldo's instructions (he's really good at explaining things in non-technical language). Download link also posted there.
You can use any Linux distro with GParted installed to set the boot flags on the card. (I highly recommend Debian, been using it for 4+ years).
http://raywaldo.com/2012/05/root-nook-tablet-with-cwm-sdcard/
I wouldn't buy that battery off the newpower site. It's a scam. You'll get a really crappy battery (3200mAH, probably chinese made, and unreliable). I would much rather buy a used GENUINE battery for the Nook Color or Tablet than a cheaply manufactured one (selling for an unreasonably high price).
If clearing the battery stats and doing a full wipe and reinstall doesn't help, I would buy a Nook Color battery for $7 off eBay. This is the last one supposedly (doubt it) http://www.ebay.com/itm/Nook-Color-...863?pt=LH_DefaultDomain_0&hash=item27d5fc185f
^^It's genuine, has a 4000mAH capacity, compatible with both the Tablet and Color, and wont explode in your face. (You really don't want to take chances with cheaply made chinese li-ions. Look on YouTube for li-ion fires/bloat (expansion)/explosions, not pretty). Be sure you also have a Torx T5 screwdriver to open up the NT. If you don't, order a set off eBay. (P.S. Don't get the chinese made ones, they're cheap and they don't work. Get a set from Craftsman if you can, those have a lifetime warranty).
Gotcha. Will try everything you mentioned and if no luck ill hit up ebay. Thanks again for all your help (and saving me from a potentially harmful choice of battery)

Have you have made progress?
Also, let me know if the battery (if you ordered one) works well. I think my Nook Color's battery is about to kick the bucket. It takes like 15 hours to charge from 15% to 100% (compared to 8-9 hours for my Nook Tablet, using the same specced charger).
My 16gb nook tablet with CM10.1 is doing the exact same thing as yours. Random touches and sudden shutdowns. The OS does not know how charged the battery is. I am eager to hear your results.
My apologies if this has been posted previously - but I cannot seem to find anyone who has had an identical issue...
My TF201 has worked perfectly since purchased - but in the last 4-6 weeks I have started to notice issues with battery life and as I have been busy with other more pressing issues I have simply been charging it more regularly and 'ignoring' the situation. However I have now realised that the problem appears to be related to the fact that the dock is not charging the tablet from it's battery reserve when the tablet is running low.
I have also noticed that when charging the unit it never gets a 'green' fully charged light on the dock and simply remains 'amber' irrelevant of how long it is left charging...
I have tried the 'cold boot' ('volume down' and power button for more than 12 seconds etc.) - which does initiate the cold boot but does appear to resolve the issue...
I have always charged both items docked and only use the original charger...
I have the same issue which started around the same time. I have also noticed that my dock is not charging although the tablet will while connected to the dock. The dock was at full battery when I noticed it was no longer transferring power to the tablet as the tablets battery got low. Now the dock is around 90% and does not increase regardless of how long it is left on charge. I have tried charging the dock by itself as well; still no luck. The tablet does indicate the dock is connected and the keyboard still funcions. This appears to be an issue with the dock battery being unable to transfer power whether from the plug or to the tablet. Any advise as to what to troubleshoot next would be appreciated.
Just started seeing the same symptoms this week. Guess this device is reaching the end of its road...

I'm having the same issue, too.
I just noticed the same behavior this past week, after having owned the tablet+dock for almost two years with no problems.
The tablet just drains completely whether it's docked or not. The dock is holding a steady 77% charge but does not transfer this charge to the tablet when it's docked. The tablet charges normally when plugged in directly to the wall (using the original charger) or when docked and the dock is plugged in to the wall. The keyboard continues to function normally.
I haven't received any system updates recently either, so I can't think of anything that has changed in the software configuration to make this happen suddenly. Glad that it's happening to other folks and not just me! Has anyone tried a factory reset?
Update: tried the factory reset, but it didn't help.
I found some discussion over on the Transformer Forums, but unfortunately I can't post a link to it. Search google for "transformer forums faq definitive thread battery" to find it.
See for example comments #335, #340, #345-353.
The first post in that thread suggests a couple of things to try, including popping the charger into the freezer (I kid you not), doing a cold boot with the dock attached, and trickle-charging the dock off a PC's USB port. If all that fails, they say to contact ASUS for a warranty repair because it's probably a hardware fault.
I've tried all of those except the trickle-charge, and in addition tried a factory reset. I also opened up the dock, disconnected the battery and reconnected it, and reseated some of the other connectors on the board. Nothing has helped.
My dock is out of warranty (it's two years old) so I suppose that's the end of the road.
Same problem
I have a TF201 with dock that worked perfectly until mid October or maybe early November. After not finding a solution online and talking to ASUS several times I sent in my tablet and dock to have it repaird as they said it was a hardware problem. ASUS wanted nearly $300 to replace the motherboard! I said thank you, but please send it back. I don't believe there is motherboard problem because it is too much of a coincidence that this proble started after receiving the GPS dongle and trying it on the TF201.
The symptoms are
1. the dock doesn't fully charge
2. the tablet will not charge from the dock
3. The tablet will fully charge when the charger is plugged into the dock
Any suggestions are really appreciated. I have done cold boots, with and without the dock.
thanks

Seeing the same symptoms here. Why on earth would they want to replace the motherboard? The tablet appears to be working just fine, it's the dock that's apparently screwed. And $300? Are they out of their ever-lovin' minds? So, were you out shipping one way, or two, if you don't mind my asking?
My solution was to buy a Note 10.1 2014.
Happening to me too:
Post copied from thread I made in error:
After suffering with stock jellybean on my Prime I decided to take the plunge and flash a custom rom.
I followed Matt Hill's guide on unlocking the bootloader and saving my back-ups. That went without a hitch. I then wanted to install the Hairybean 2.3.1 ROM but was still on flatline. I then flashed TWRP 2.5 and then again followed the hairybean install instructions to the letter. I used their supplied bootloader. That also went without a hitch and the Prime itself is running extremely well and I'm loving the new smoothness. When turning the machine on the Prime wanted to update the firmware on it which I declined. When I rebooted, it decided to update anyway. Still. Worked fine and was still silky smooth.
However. I have now noticed that my dock refuses to charge. If I plug the adapter into the dock and attach the tablet to the dock, the tablet will charge but the dock refuses to (even if the tablet is at 100%). I have tried removing the tablet and charging the dock on its own but it refuses. The light comes on the side, but doesn't indicate it is charging. Whats odd, is that when I plug the charger into the tablet and dock together, the widget shows the battery of the dock charges for a second, before then deciding not to. My tablet is at 100% but the dock is stuck at 16%.
Any ideas what might be causing this? Or how I can resolve it?
Thank you!

I have tried the 'cold boot' ('volume down' and power button for more than 12 seconds etc.) - which does initiate the cold boot but does appear to resolve the issue...
I have always charged both items docked and only use the original charger...

Facing the same problem. Tablet charges fine while connected to dock, but dock fails to charge. Steady at 5%. It continuously flashes amber light when charger is plugged in. Tablet is out of warranty (about 20 months old), so not sure what to do.
has anyone found a fix for this? mine is doing the same thing dock doesnt seem to be doing its job by powering the tablet really love my prime dont want to have to go and buy a new tablet just because the dock wont charge it.
My wife and I own a TF201 and have found that out of the 2 chargers, only 1 works to charge the tablets now and the other doesn't, and it's all in the actual plug, not the cable.
I've tried a bunch of other android and USB plugs and nothing works to charge them at all.
Have been looking at getting a genuine replacement charger for it so that we can charge both at the same time instead of sharing, but it works for the moment.
You might want to try a new charger too?
Same problem
[Exactly the same problems. TF201 Keyboard won't charge although the tablet does charge when power plugged into keyboard - but to only 99%. When plugged in directly, it happily charges to 100%, therefore the assumption is that the tablet is working fine. The keyboard won't charge at all under any circumstances and it is now down to 43% charge left - Aaaagh!
Crazy thing is that my partner's TF301 is now exhibiting the same symptoms!
I, too, contacted ASUS and they informed me it would cost £45 + VAT just to inspect the 201 and then cost ??? for repair.
Reading the other forum entries it almost sounds as if ASUS have fitted an obsolescence chip!! Just too many coincidences here.
My response: I've recently bought a new ASUS Windows 8 Transformer - I must be mad!
I recently got this same problem, with the classic symptoms:
1. the dock won't charge
2. the tablet will not charge from the dock
3. only the tablet will charge when the tablet is docked and the charger is plugged into the dock
I tried all the tricks I could find on the interweb - cold boots, trickle charging overnight, I even put my charger in the freezer. I even tried a custom ROM (ok, I was planning to do that anyway )
ASUS wanted £45 just to look at it, so I took the plunge and ordered a new dock battery for £30 off ebay (shipped from china). It took a few weeks to arrive, but it has solved the problem! It's a 15 minute job to swap it over, and as I write this, the dock is now charging!!! :good:
If anyone else wants to try it, the dock battery code for my UK model is C21-TF201D. You will need a small phillips head screwdriver and a small Torx star screwdriver to get the dock apart, but it's easy enough. There are tutorials on youtube and plenty of how-to's out there.
So between a battery and a new ROM, it feels like a new tablet again!! :good:
Same Problem + bulging
I have the same problem with my keyboard dock. Now the dock looks bulging in the middle, I think because of the battery. Other functions except charging still works. I cannot flip close tablet and dock attached because of the bulging.
Since the waranty is over, is it possible the dock still works without battery (if I remove the battery)? I'm afraid the battery will explode if I keep using it in this condition. If this is possible maybe I will ask ASUS Service Center to remove the battery since I don't want pay extra money to replace the battery, last time they said its about 85 USD.
Dock registers to tablet, I can see battery level.
Dock Battery is not charging
Dock battery is discharging slowly
It's possible to charge tablet through Dock
I guess something is broken inside so I'm going to open it. I've seen many videos but they are not helpful in this case.
Does someone have experience? Is it possible that battery pack is broken itself?

Yes. I just removed the battery and closed it again without it.
It's look like 2 batteries/cells are good itself but internal controller is brkoen somehow.
Hi, I just installed HB 2.31 on my Asus TF201 and im having an issue. The problem is every time I plug it in to charge it keeps making the "ding" sound and coming out off sleep. Once it wakes its fine charges like normal till I let it go to sleep again, then same thing it dings and wakes up. I'm using the wall charger and this is on a fresh install. The problem only happens on this rom, works fine on stock and other custom roms. Sorry I would post this in the DEVDB but I don't have enough posts.

Usually caused by using a third party charger or, in my case, using US charger with UK adapter.
Not really a problem since it charges fine. If the screen coming on annoys you, put something over the top :good:.

You're right it is a third party charger. Thanks for the quick reply.
