So there is another thread sort of like this a bit below this one, but it's not quite the same situation, so I figured I'd make my own thread. My gf's tf101 has been working fine for the last couple of months, and then a couple of days ago, she found that as soon as she unplugged the tablet, it would shut off instantly. Once it's plugged back into the charger, it will boot and work fine. But, it will only work at all when plugged into the charger. When removed, no matter how long you hold the power button down, it won't turn on. I tried plugging it into the computer, and when I press the power button, it will flash the boot screen for about half a second, and then dies again. Keeps doing that, and will not stay on. Any suggestions, before an RMA? Anything to try?
Thanks.
What is the battery level showing when it is plugged in and on? Also check it with the Dual Battery Widget to see what that reports for battery charge/
I would back up all the data and apps, back up any important files and try a factory data reset. If that does not help, I would send it in for repair.
Ok, I was thinking about trying a factory reset next. The tablet shows 99% battery life left.

Hi all,
So my transformer is bricked... completely been trying hard reboot, APX mode, holding power button, HDMI output the list goes on.
My only final resort is what I've read is draining the battery down and trying to recharge it? (Just need some confirmation here please if possible).
I've kept it in the dock, what I've noticed is, in the morning it was green LED now its gone to the amber so something is draining the battery I"m hoping I can get this down to 0.
How long do you guys think with both dock + pad and most likely on standby. Not too sure of the issue here
Anyway, I'm really reluctant to send this back to Asus RMA because in short:
1. First time I sent it, it got returned like a squeaky box. Every where you held it you heard a creak like it was about to snap. They didn't fix some things, and more dust ended up in my camera lens... + had to pay postage..
2. Half fixed, came back with wrong firmware (TW --> US). Could never update ever again, so microsd card updates FTW. No way was I planning on spending an extra month sending my TF back and forth... I paid extra to get the first batch B40 lol.. They replaced everything inside my TF motherboard, screen, Inside LED!?, buttons. Close to the works..
This happened right after I upgraded to ICS, it was the US stock rom booted up fine. my apps were updating, and as everyone else was saying about how some apps caused ICS to slow down I wasn't aware so I thought I would shut it down and power it back up. Since then it's not been able to come up ever again... Any suggestions?
What do you think?
Thanks in advanced.
One other thing, could someone check.. when tablet is docked and OFF. Do the usb ports still work?
Right now, when docked but "bricked" I can still charge my phone via USB.. If someone could test this that would be much appreciated as that could at least eliminate that my TF's battery is dead, right?
get it off the dock, hold volup+pwr, count to six and leave it for a couple of days. You can test if it's empty when you plug it in your pc via the cable. If you get the device plugged sound it means there's still juice there - unplug and press again volup+pwr. when you unplug it from the pc the tab shuts itself down.
if you don't volup+pwr before you plug in the usb it won't turn itself on. but it turns off automatically at unplug, as I said.
after the battery is down, plug the tab to the charger. I don't have the dock so I can only speak about the tab itself. Don't know why, but it works for me everytime. Hope it fixes yours, then, if possible, root and flash something.

Hi there,
Thanks, I'll that a try.
It's definitely charging and discharging, the battery brick is warm.. I've never had to connect my tablet to a windows PC. Today I did, it didn't make a sound.. Do I need to fully charge to be able to turn it on?
Normally not. I plug mine to the charger, I don't remember if it stats or I have to press power, when it boots the battery stays at 0% for several minutes.
Sorry for the late reply, did you manage to wake it? It's a long procedure of waiting mainly and can get annoying.
I'm still trying, earlier you had a thread about it poping up through the computer. What was the command you used in Linux?
Windows gives me nothign even when there was power in it.
Thanks.
Thank you sooo much!! It finally has powered back on, I hope this doesn't happen again.
My Asus Transformer on ICS was rooted and fine. Then after the latest update the other day, I noticed yesterday that I lost root. Then today I powered it off and now it won't turn back on at all. Connecting it to the dock shows no sign of life. Plugging it in on it's own to both a PC and wall outlet and still no signs of life. ADB doesn't detect it. Windows doesn't detect it. Holding down the power button forever doesn't do anything. Power button and volume down doesn't do anything.
Do I have any other option other than sending it for repair/warranty? I've tried searching on here and Google and everything just says to boot into recovery. But that's not doing anything for me.
Please help.
Thanks.

It may have gotten "undercharged". When that happens it will take forever to show signs of life after its plugged in. Try leaving it plugged into the wall outlet overnight and see if it fixes it.

I was thinking the same thing. My Nook Tablet recently had this happen and I thought the thing was completely toast. I figured I'd give it one last shot and just plug it in for a while and like a 1/2 hour later, it suddenly woke up.
Hope the situation works out the same for you OP.
I've had it plugged in overnight and still nothing at all.
Now thinking about it, the reason it was shut it off (by my wife) was because it was glitching. It was playing music in the background from a game that wouldn't shut down. I'm guessing it was stuck in memory or something. So I'm wondering if this game or whatever is still somehow running and the device isn't actually completely shut down. I'm gonna do the opposite and leave it unplugged for the day. Let the battery completely deplete, hopefully shutting down fully and killing that process. Worth a shot.
try pressing power and vol down for like 30 seconds. Another thing I've seen people do is try plugging it in and holding power for 30 seconds. Also try plugging into computer totrickle charge for a bit. Hope any of this helps.

Tried those already with no luck, but thanks for the suggestion.
I've tried holding the power button for minutes at a time too. Power and volume down for minutes at a time. Plugged in and not plugged in. With and without memory card in while plugged in and not plugged in.
Update: I think there is some merit to my theory. Left it unplugged for a full day and then plugged it in and after a few tries it BOOTED! Working just fine ever since too and the strange thing is, the battery barely depleted at all.
So something was possibly running that was preventing it from fully shutting down? I don't know. Strange.
Had the same issue over the weekend
I wish I had seen your post prior to calling ASUS for support, I went through all the troubleshooting steps you suggested, had no luck. I did not wait long enough to let the battery fully discharge to see if that fixed it and my TF 101 is now on route to TX for warranty repair (I am hoping that I now may end up with a tablet with a few more of the issues ironed out also). But if not, but the time I get it back I will probably flash it with a custom ROM (probably Revolver), that may be out of Beta by that time.
We shall see.
I posted this to another similar thread but they have solved their problem but mine is not solved.
A little background:
It was most recently upgraded to the the newest OTA and been stable since then. The unit is nearly 1 year old B50. So I know all about holding the power button down for different lengths for different purposes. It is NOT that. Until two days ago, everything was working fine.
First, I couldn't turn it on. I thought since I was travelling and using it a lot, it just ran the battery down. So when I got to the hotel room, I plugged it into the wall charger and it turned on. I was relieved for a while. Then I checked the battery (dual battery widget) and it shows 86%. When I was leaving the room, i pulled it off the wall and bam...it shuts down completely. Curious, I plugged in the charger and it boots back up (asus logo and whirling circle). I decided to leave it plugged in all night.
The next morning, I pulled it off the wall and bam, complete shut down. I plugged it back in and check the battery status. Still showing 86% and I notice it is not charging. I check the battery summary and it shows, battery = unknown error.
I did the hard reset (with it plugged in) VolDown/Power sequence. No luck. I decided to wait until i get home to test further.
At home, I plugged it into the dock. Widget shows the base battery is charging but the tablet is not charging. (it turns on when plugged into the base). It stays on even after I unplugged the base from the charger but the moment i remove the tablet from the base, it shuts of completely.
At that time, I decided to do a complete factory reset. After the reset, it is still having the same problem and dual battery widget is reporting the same unknown error problem.
In summary:
1) The unit will not turn on if I don't have the power cable plugged in.
2) When the cable is pulled out, the unit turns off and will not turn back on
3) When the cable is plugged in, it turns on and work just fine
4) When I put it on the keyboard dock, it turns on and work just fine
5) When I pull it out of the keyboard, it turns off and will not turn back on
6) I have soft reset, hard reset and factory reset (all with power plugged in) because nothing will happen without the power plugged in
7) Battery status shows 86% but not charging:
--When plugged into the wall
8) Battery status shows 86% but not charging while in the dock.
--The dock battery shows that it is charging and the light on the dock is green
I have tested and knows the charger works and the dock battery works.
The main unit battery will not deplete and will not charge and will not keep the unit running.
What do I need to do? Any thoughts? I would greatly appreciate some help.
Are you rooted? and did you try to clear the battery stats?
https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en
you can use that to clear your previous battery stats, and may help with getting a better reading on whats wrong. a messed up battery stat maybe messing with the charging process.
No, it is not rooted. I have just reset to factory settings again. But I might take that route soon if I don't hear from Asus. Is there an good detailed instructions for rooting my TF101?

http://forum.xda-developers.com/showthread.php?t=1366743
you can start there. i got rooted when it was in HC didnt like the stock feel, so went to Prime Rom( honeycomb builds) the dev kept it close to stock but with some tweaks to the kernel. was a bit afraid to root at first, but just read through the tutorials, and just did it.
anyways Good luck!!
OK, nothing else seems to work. So, I am trying to go down this rooting road and using the battery calliberation tool.
As I was reading through the instructions, I find the build version supported is much older than mine (9.2.1.21) so, unless i am reading something wrong, this will not work.
Anyone has any other thoughts? Thanks in advance.
I plugged my phone in last night and when I woke up today it was off. I pulled out the charging cord and held the power button with no effect. Thinking the cord may have slipped partly out and let the phone die, I plugged it back in and was greeted by the battery charging screen, showing full charge. I pressed the power button and the phone went black. On further investigation, it seems my press of the power button didn't have to do with it turning off, as whenever I plug it in it shows the full battery screen for a couple of seconds before turning off again. If I unplug it and plug it back in it just repeats this. I've reseated the battery, I've tried holding volume down and the power button, and nothing's changed the phone's behavior. The phone is completely stock, and never opened beyond the battery and card doors.
It's pretty old and I'm pretty sure I do have an upgrade available, so I'm not too upset if I have to buy a new phone, but I'd like to confirm that it is FUBAR before I go that far, and I'd like to be able to extract my data if possible. Any suggestions would be appreciated.

If you have access to another battery, you could try that, but since you're seeing the full battery symbol I'm guessing that that's not the issue. You can always recover your sdcard data by putting it in a card reader, but the phone's apps, app data, and settings may be more difficult.
Well, turns out the problem was much less serious than I thought: my charging cord has bitten the dust. I'm not sure why I've been seeing the full battery, but when I took it to the AT&T store, the person who helped me plugged it in and it started right up. I just need to get a cable that's not my years-old piece of crap that came with the phone.
I've had this phone 3 years and it worked well. It's an unlocked ATT phone so no OTA updates other than the standard app updates. It's on Lollipop 5.1. Been working perfectly fine until yesterday, I was watching the CBS app, when the phone rebooted. Now it's stuck on a boot loop and initally went to optimizing apps which it rarely finishes but the times it does, the phone just powers off. It then got into another loop later last night where it'd get to the Kyocera logo then reboot over and over. I let it do that until the battery died 2.5 hours later. Then I kept attempting to boot until the batter was entirely drained to the point it wouldn't attempt to power up any more.(battery is not removable on this model). I've now charged it up, trying to enter recovery mode with power+volume down. That doesn't seem to register. Tried volume up+volume down+power with no effect. Now after charging, it will do the reboot loop mentioned earlier to the Kyocera logo. If I plug it into a charger, it will go to the optimizing apps portion and repeat the above. At the optimizing apps screen, if I unplug the charger, the phone powers off immediately. It appears to be holding a charge according to the charge indicator and the fact that I can try to boot over and over unplugged. Any suggestions? Phone wasn't dropped or damaged in anyway. Very weird what could have happened.
An update: Phone finally got past the "optimizing app" phase last night sitting on the charger. Out of no where the phone booted completely. However, it only works while plugged in. If I remove the charging cord, the phone shuts down after about 2 seconds. Booting without charging cord results in the same boot loop. I've considered the battery has failed however when plugging in the charger, battery shows 100% and it will decrease appropriately over time. I'm thinking there must be a hardware issues at this point. Somewhwere in the charging/power circuit. Any other suggestions?
Last update I guess. I was able to keep the phone up and booted as long as it was plugged into a wall charger. PC USB was not enough. I managed to grab my photos etc. thankfully. Factory reset the phone from the settings menu. Unplugged from charger, ran for about 2 minutes. Still said 99% charged, then went into boot loop again. Phone still shows near full charge if you let it run for awhile and decrements the charge state appropriately as time goes on. However, i guess this 3 year old phone is toast. No known reason for it to fail unfortunately. Thought I'd share the experience if anyone else has this issue.

I have the same exact problem. It started the crazy booting process in my pocket, and I did all the same things you did. Factory reset didn't correct the problem, so I'm think the battery has had a stroke. Sine your problem and my problem are very close to the same time frame, our phones are also probably about the same age, and its a quality control issue. Not bad quality control, just that these batteries were designed to last X number of months or cycles, and probably they died. Too bad, because my E6560 is the very best cell phone I have ever owned. Built like a tank and thank God for that.
