[Q] Strange charging behavior - Asus Transformer TF700

I'm running the latest and greatest CROMI X on my TF700 and I experience the occasional strange behavior when plugged in to the stock power supply. I have assumed that it was a faulty piece of hardware but am looking for other experience before I endure the trauma of returning the unit.
Firstly, I cannot charge it with the tablet off at all. When it's off and I plug in the power supply it boots the tablet. If I try to power down while plugged in, it simply reboots immediately.
Of greatest concern is that after plugging in sometimes I look at it a while later or even after overnight and will find it some peculiar state of being on and totally unresponsive and very hot. It appears that the screen is on but totally grey or perhaps the backlight (does it have one?) is lit. In this state, I can't power it off by holding the power button down and can only restart it with the power button/volume down combination.
Any help will be appreciated.

Are you running Hund's kernel by any chance?
Tell us a little more of your setup. And/or try flashing the rom with different options.

I'm running CROMI-X 4.6.4-10.6.1.15.3/US ODEX, Kernel version [email protected] #5.
Since posting have discovered that I can in fact power down when it's plugged into the charger. I'm feeling confident that this is a hardware fault with the plug/port. I don't know of course why the tablet goes in to the state I've described.
I am entirely reluctant to RMA the tablet as I am unlocked, rooted, etc. Have a Square Trade warranty, may pursue replacement that way. Dn't want to wake up to a burning tablet/house.

I think these chargers have issues. I'm rooted but locked and I can't charge the tablet with the power off at all unless I power it off after plugging it in also. I also have a problem about every other charge where my charger isn't being detected when I plug it in. I have to disconnect and reconnect the two parts of the charger for the tablet to detect it. I returned my first TF700 to Amazon the first week I had it because of this very same behavior and this one has it as well.

Right you first "issue" is 100% normal. This is how Asus have designed it to work currently. If the device is powered off and you plug it in it will boot. 100% of the time on every single transformer out there.
Your second issue sounds like the kernel is getting stuck but without a log it's hard to know. I've seen it happen to me and the easiest fix was to reflash the rom and kernel again which fixed it.

[Q] Please Help -> Dead Transformer? At wits end...[FIXED]

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.

[Q] tablet wont power on without power cable

my tablet wont power on unless i plug in the power cable and hook it up to the power outlet. this happens at any battery charge level. i tried at >90% charge, at around 60% and when the tablet was at around 5% charge. the tablet just won't turn on unless i hook it up to the outlet no matter how long i keep the power button down. is this normal?
i have not done any modifications to the os. i am not rooted, no custom recovery. i am on ics 4.0.3 on the .21 patch.
my tablet has been rebooting every now and then like many of you have experienced.
today i lost sound completely. alarm clock would not ring, no sound in aps. i forgot to check if i had sound in pandora over headphones unfortunately. a reboot fixed this. did anyone experienced this?
"search" seems to be down so i could not find any similar problems to mine. this is why i opened this thread.
The loosing sound is a known ICS problem. A reboot will fix it.
As for your powering on problem. Once it come on after yo uplug in the charger cable, does the power button work normally? Does it shut the TF down when you push it? Could be a bad power button.
the power button works perfectly. i can shut down and wake up the screen from it when the tablet is powered on. if i hold down the power button when the tablet is turned it the shutdown menu pops up so i assume the button works fine.
something strange happens when the tablet is powered off. nobody reported this problem until now on the .21 patch?
How old is your tablet?
I think the battery is the issue.
Edit:
It could also be a hardware problem. Send it back to the shop and make them repair it.
Good luck!

i have no idea how old my tablet is. i bought it a week ago off cowboom during one of their fire sales. maybe i should just send it back.

Yes, it would be better to go back instead of struggling with it.

There was another thread: http://forum.xda-developers.com/showthread.php?t=1520844
Someone reported the same issue even after having the tablet back from RMA.
I'm experiencing the same issue and I don't know what to do, maybe this is just a firmware issue, but I don't know how to report it effectively to Asus.

Did I fry my phone?!

I really dont understand what happened.
I'm running one of sean's builds for a few weeks now and everything has been running as expected. However, after charging from a higher amp charger, (An ASUS transformer wall charger) my phone now only bootloops. The only time I broke the bootloop was when I plugged it into my car charger.
I don't know what to do, is it possible to save or did I fry it with my charger?
Also, the phone powers on to the first and second samsung boot screens, then the screen goes dark, the phone vibrates 5-6 times, and restarts.
EDIT: I managed to get into recovery mode once, but it turned off from the seemingly bad power.
I have also tried a stock battery as well as an extended battery.
I used a 2A charger to charge my phone a couple of times, the phone only takes as much as it needs so I doubt that's the cause.
Can you get into recovery with OEM charger connected? And what about download mode?

There have been issues with the power button getting stuck and causing what seems like a boot loop. Check that first.

Is it possible something on my ROM spontaneously corrupted?
And my phone can do anything, except it always turns off. Sometimes I can get to the boot screen, but it turns off and tries to restart. So, I'm basically screwed with my warranty because there's enough for them to tell I'm rooted, but the phone won't stay on long enough to Odin.
Also I checked my power button, it doesn't appear to be stuck.
can it stay in dl mode w/o restarting, if yes go back to stock
To be honest the way you describe the issue it sounds like the power button is internally stuck or something. Try measuring how long since it boots to when it restarts if its always the same and around 10 seconds it's probably a hard reset from the power button.
I will start measuring that in a minute, thanks.
And after numerous attempts I finally managed to get it to go into download mode!
After timing it, it's always on 7.5-8 seconds of the reset.
So if that's the issue, is that fixable?
sounds like the power button, press really hard repeatedly on the button until it unsticks

CM9 Skyrocket

Randomly Shuts Off / Won't Reboot

I've had my TF300 for a few months now. It's been unlocked since day one, and is currently running CM10 stable (probably going to try a 10.1 Nightly today). Recently it has been randomly shutting down. No warning or anything, I'll just be watching a video or browsing the web and boom, it's off. Screen is black and everything.
This wouldn't be THAT bad but it doesn't automatically reboot, and it's very difficult to get it to boot back up. I've tried holding the power button for over a full minute, every combination of vol+ and power and vol- and power, and most of the time (not every time), nothing seems to do the trick but sticking it on the charger for a while and leaving it alone. Then I'll just hit the power button like normal and it will fire right up. It's done this 3 times now.
So what do you guys think? Hardware or software issue? And despite being unlocked, do you think ASUS would warranty it if I restored the factory image, if it is a hardware issue?
Have you got it overlocked? If so, try turning the tablet down. Watching videos may be too much for the tablet if it's overclocked. Another way to see if it's software or hardware is to switch ROMs and see if it still does it. If so then it very well may be hardware related.
As for the the warranty, from what I understand, Asus will still cover hardware issues even if it's unlocked. I do not know from personal experience, only from what I've read here from other members.

Not overclocked, it was a thought that occurred to me, too, but it's just running the included CM kernel at the stock speeds. I'll give CM10.1 a try tonight and see if that resolves it. Thanks for the advice.
So I think I figured it out. This thing is straight up not reporting battery stats. I let it fully charge last night, and now after unplugging its been at 100% for about an hour of straight use and two (normal) reboots. Tried deleting batterystats.bin but it made no difference. I'm going to run it down and see what happens...
Still no go. It was totally fine until the battery hit about 45%, then shut off and was unresponsive. When I plugged it back in, the light blinked for a few minutes, then I was able to power it up like normal. Has the battery gone bad?
Try Installing STOCK ROM
I have the similar issues with CM10. But it doesn't happen when I am using it(playing games, surfing internet or watching movies).
It happens only when the tab is not being used for more than 2-3 hours. Pressing Power button doesn't do anything and I have to press the power button for at least 1 minutes to get it rebooted.
I installed Stock 10.4.2.18 rooted(http://forum.xda-developers.com/showthread.php?t=2033205) and I don't see that issue anymore.
Now I am trying CleanROM Inheritance 3.0.4(http://forum.xda-developers.com/showthread.php?t=2049322) to see how it goes as it is based on the Stock ROM.
Same exact happened to me yesterday...i was scared for a min or two...it finally booted back and been fine since...im on cleanrom unlocked and rooted no overclock

I have the same problem, and my non-scientific observation leads me to suspect it was worse on the stock ROM. Also, I have this problem where wifi will not work (upon waking the tablet, it says wifi is off, though I had not turned it off), and I have to reboot it in order to get wifi to connect. I don't know if the issues are related.

Cannot start or power on

Something really strange happened.
Yesterday, when i was using my tf700, everything was fine. i connected the tf700 to my computer and dragged couple movies in to watch later. Batter was around 30% so i plugged into a wall charge to charge so i can use later. after half an hour, went back and tried using it. it won't turn on! tried connecting it to my computer, my computer can't recognize it. Tried connecting to the wall charge, the charge light didn't turn orange. Tried using my tf300 cable to see if it's cable issue, still no luck. Tried using reset button on top of HDMI port, no luck. Tried volume down or volume up plus power to reboot, no luck. I think it's dead....Only had it for a year..
Worst of all, it's unlocked, rooted to a custom ROM. So no warranty. I tried googling and searching on XDA, not that many people encountered this issue. Any luck on saving it?
Any suggestions would be much appreciated.
Thanks!!!

It looks like your battery on your device totally drain and either your charger or cable or your tab connector is bad so your device can't be charged. If you can narrow down the issue, then you can get helps faster.. Good luck...:fingers-crossed:

Thanks LetMeKnow for the quick response. I'm pretty sure it's not the cable or the charger because i tested with my TF300 cable and charger. But how can i tell if it's the connector?
Thanks!
Mine did the exact same thing. It is just completely dead. I'm totally at a loss as to what to do. Anyone know of a way to force this thing to wake up?

Same issue here. Just charged mine up(yes it charges), but it will not turn on. It had been sitting for a while so I assumed it just needed a charge. Fully charged until light went green. Tablet will not do anything.

You could give this a shot...
Hold both power button + volume up for about 10 seconds. You should feel a first vibration and continue holding them until you feel the second vibration. As soon as you feel the second vibration, you need to release the volume up button and keep holding the power button until you feel the third vibration and release the power button.. At this point, your device should boot into your system..
You may want to try a few times for it to work..good luck and please report back..:fingers-crossed:

Yeah I've tried that and the reset button, but get no vibrations. I guess I'll wait for the battery to full discharge again and then see if it will work. Otherwise I guess I'm SOL. No idea what happened.
I tried letting it sit unplugged for a couple of days to completely discharge the battery and then plugged it in to let it charge. No lights, no vibrations• nothing. I'm giving up ans just ordered a Samsung Note Tablet 10.1 2014 Edition, 32GB. When I get it I'll root it so I can use Titanium Backup to restore my data files. I never planned on this tablet just dying like this. It's only a little over a year old. I was thinking of upgrading to Asus's new TF701 but I'm done with them.
Good luck with yours. Hope it springs to life for you.

This is by far the worst Asus experience i ever had. I used to buy their products quite a bit, and i am completely disappointed in their products now. They create a tablet so slow that is almost usable so many users to need unlock and install custom ROMs. Therefore, void the warranty. Then provide such bad quality that it fails not even after 1 full year. (1 week till a year) Then is going to charge me $300 to have them fix it. I can buy a new one for that price.
Anybody out there as frustrated with Asus products as I am?
