leave it plugged into the computer for afew hours then try turning it on

Or better yet, use the charger for at least 4 hours.

thanks- the battery had a full charge when the screen went off

no. it does not

I have charged it for more than 4 hours and still it does not turn on.
I called T-mobile and they are telling me since it was bought in Dec I have to call Samsung. I called Samsung and they are open Monday through Friday 9am-5pm.
I have insurance on it and I asked T-mobile what am I paying insurance for and they told me only if its broken or has water damage can it be replaced under the insurance.
So I will take it to the TMO store today to see if there is something they can do....

I went to TMO store and they got me some help. i spoke to a TMO person who will contact Samsung and taker care of it for me. they are scheduled to call me tomorrow. since it is still under warranty and i have not opened it they will try to help. just a note i don't know if this is relevant, it gets warm when it charging and then cold when the battery is dead. right now i have it sitting until it drains.
i am waiting to hear from Samsung. lets hope they have good news.
I will keep you posted.

I had a similar thing happen to me last week as well. I went to sleep, and then didn't want to turn on anymore. I had it plugged into the computer and after about 30 minutes, it turned on.

Yeah... it's mine too and I solved by press the Power button while another finger touching on Screen just about 1~2 min and it wakes up. I don't know what is the reason while the TAB doesn't turn on.
FYI

Thanks for all of the helpful suggestions. Tab is on its way to texas to the samsung repair center. I will not see it again for over a week. So sad
tab you will be missed. I hope you return with some treats :i

hey, what about your tab now?
im facing the same problem today.
maybe u got a few tips?

A very wierd Nexus 7 experience

I was one of the early pre-orders and received my Nexus 7 last Tuesday evening (7/17).
Like most users, I checked it out for problems: screen, mic, etc.
Everything checked out fine.
I did some customization, downloaded some apps, tried out all the new features.
Everything worked well.
I had connected it to my PC, no problems. Rebooted it, no problems.
After about 6 hours, I put my Nexus 7 to sleep (not shutdown) and
started to prepare to go to sleep myself.
After about 5 minutes or so, I decided to download one more app.
I tried to wake up my device -- and it would not wake up!
I tried a long press on the power button -- still no good.
Thinking maybe the screen had gone bad, I tried to connect
it to my PC to see if it could be recognized -- no good!
Yikes, could my Nexus 7 have died? I decided to try
to charge it, plugging the charger into the wall. No little
charging icon showed up on the screen
I decided to just let it charge overnight and see what happens.
The next morning, the Device still would not power up
I called google play and told them my story and they
said they would start the process of sending me a new
Nexus 7.
I started looking on the Forums, to see if anyone had
the same experience. Some people suggested that
I hold the power button down for 30+ seconds.
I tried, 30, 60, 90 seconds ... still no good.
Over the following days, while waiting for my RMA process to play out,
I would periodically pick up my Nexus and try the power button -- no good.
Today, 9 days later, on a whim I decided to again plug my device
into the charger. Believe it or not, the charger icon went on!!!!
After charging it for about 90 minutes, I booted it up and everything
was working again!
The replacement Nexus has not shipped yet, so I have a few days
to see if this problem occurs again.
My guess is that my device got into some hardware freeze situation.
The battery finally ran out of juice which caused the machine to
completely shut down -- which allowed me to re-charge it today.
Any other thoughts?

>Any other thoughts?
Maybe you can give the hidden reset button a try the next time?
NB: For the unfamiliar, a video teardown showed a reset button at top of the unit, but no hole through the casing to access it.

I did do that at one point. However, if I did it at a point
where the battery actually had run down I still would
have needed to re-charge the device -- which I did not
even try until today. Nice to know though.

I haven't had any issues with my nexus whatsoever thus far. I really hope these are anomolies.

Sounds like the ever so familiar sleep of death that occurs on custom Roms. It requires the reset button or let the battery die

I'm kinda glad I didn't get my Nexus 7 yet. LoL!! All these issues ppL are having.

[Q] Is my Nexus 7 dead? Please give me options to charge/turn on

Good evening everyone, I have a Nexus 7 8gb, but the thing is, I cannot turn it on now.
It happened as follows:
I was using it every now and then, mostly to read and play.
I was using the charger to charge my cellphone too (XTC Explorer) as it was a lot faster, being 2amp/h.
I updated the cell to 4.1 and at the same week noted the battery wasn't running that long, but blamed it to the rom.
The cellphone also took a lot longer to charge with the nexus charger, yet again I blamed the rom.
I noticed the Nex was at 8% while reading so decided to charge it, but I guess I forgotten.
The next time I wanted to use it it wouldn't turn on. I figure it had no battery.
I plugged the nexus charger to the nexus a whole night and in the morning it still wouldn't turn on.
I figured something must be wrong with the charger, so I tried with the cellphone and nook color charger, but both are .5 amps/hour.
It wouldn't charge, neither connected to the pc (also .5a/h via usb) so I tried a psp go charger, as it is rated at 1.5 amp/hour, much closer.
I connected it at night and saw the charging icon (white on black battery with the ray) and left it overnight.
The next morning it wouldn't turn on either.
I've bought it almost two months ago and I really enjoy it =) but now I'm desperate.
I cannot call google play for the warrant because I'm in Argentina, and I don't believe they will ship me a replacement, nor anything. This one my brother bought from them, but he went back to US a few days ago, and I didn't think of giving it to him to RMA.
I tried keeping the on button, for 5 secs, 30 sec, 90 secs, 120 secs, and no dice. Also tried holding the Up Volume key to restart it, but no chance.
Please help!

Had a similar issue to this over the weekend after not charging for 2 days and the battery going dead. I let it sit on the original charger overnight and for some reason it did not charge. It kept booting and shutting down once it booted due to a low battery warning. It eventually got to the point where the screen would go to fuzzy lines and light but no boot.
To finally get it working I did a combination of a few things but don't actually know what got it going.
Put it on a different (kindle) charger and let it sit for an hour or 2, did several hard resets holding both just the power and also the up/down volume and power all at the same time for up to 60 plus seconds. I switched back to the stock charger and did an additional hard boot by holding just the power for 30+ seconds and it started booting and charging.
I did however put it on the charge again last night and noticed this morning it was still at half battery and didn't get a charge. I ended up putting it on a mifi charger this morning and it's charging again so don't know what is up with the stock charger. Also, have all the latest updates to 4.2 as far as I know as there have been charging issues reported with earlier versions...

Try this, it just saved my device:

try holding down the volume DOWN and the power key for 10 seconds, then release the power key and keep the volume down key pressed, and it will force the unit to restart into the bootloader from any stage, its effectively like pushing the restart button on the front of a computer and constantly pressing the delete key to get into the bios.

Xperia T not charging occasional boots

I hate making new threads but I just had to:
Okay so first my problem:is that the phone is dead. I used it till it drained and now it refuses to start. The red light comes on but battery does not seem to charge fast enough and once it acquires the minimal charge, it spontaneously reboots and wastes that battery. Then I am back to square one. This keeps on happening. It has become really annoying.
I have read many threads. Actually I spent the last two hours or so trying various things. So if someone can tell me a solution, it would be great!

Any help is appreciated because I am helpless right now.

The first thing to do/try is to charge it for at least 24hs without touching it, just let it charge. Then try to turn it on.

I tried. It charges a little and it turns itself on and burns out the charge. But I fixed it! After a lot of time!
Thank you for your interest. I will hit thanks later since I am on my limit.

I've got this exact problem and I've tried all the 'fixes' google has to offer and none work. When I plug it in to charge no light comes on the only way to get it to charge is to hold VOL UP while pressing the Power button. You then have to hold the power button down to keep the charging light lit. However, once it has enough juice to boot it does just that (because the power button is held I guess) It boots all the way into Android and then shuts down because it does not have enough power (and isn't detecting the USB power).
How did you fix yours?
EDIT: FYI My Xperia T has not been rooted and is running the latest official firmware 4.3.

OK I've tried that and it's still not charging (no red light). The battery is definitely flat as I get no lights at all when pressing the power button without it being connected to power. I can only get the power light to come on by holding the power button. It's been sat here connected to the charger for 2 hours. Going to try the rubber band trick again (holding the power button down).

2 hours charging is definitely not long enough. Just let it charge for 24 hours and don't mess with it in the mean time.

OK I got the usual power up and instant power down because of low power. However I've banded the power button and the Vol Up buttons and it appears to be accepting charge without starting the phone. I'm going to leave it charge overnight hopefully it wont continuously boot cycle... Balls as I wrote this it had been charging for the longest time yet (about 40 mins) still not enough to get ti to boot android without instantly shutting down

It did charge for 24Hours no change, so then I tried (as advised elsewhere) to charge it again this time I waited 2 hours expecting the red light to come on but nothing...
The advice was charge for 24hours - no light shows as the battery is now discharging. The battery was totally flat this afternoon (no blinking lights when pressing power). Then disconnect the power and try and charge it, it should now show it's charging but it never did, maybe I should have waited longer.

OK the final 'fix' I found while googling this was to take the back off and disconnect the battery. This seems to have worked immediately my phone showed a red light and then booted up showing the battery charging symbol on screen - a welcome sight!

Phone keeps shutting off!!!!

Nexus 6 works for a few minutes then shuts off unless it is plugged. This is crazy. Has anyone heard of such a thing? Phone was working perfectly for 2 months until a few days ago.

You mean it's happening for battery or it just force shutdown? If force shutdown then it's a common bug. Or else, it's different issue

Screen just goes black and it's off. Then when I turn it back on it usually makes it to the lock screen and shuts off again

Does it do this regardless of the charge level? Like it does it even at 100%?

I encountered this with my Nexus 6 last week. Whenever it was below 70% battery the phone would just shut off. Sometimes I could boot back up and use for a little while but soon it'd shut off again. On other occasions it would just think that it doesn't have enough battery to power on at all despite knowing full well it has at least 69%.
Same thing with you, when on AC power it worked fine.
I tried a few things to fix it, factory reset, alternative kernel, re-encrypt + factory reset. None of the above fixed it so I sent it back to Motorola. I'm expecting it back on Monday!
reddit and other android forums have similar posts about "randomly shutting off" so it seems we're not alone.

i would try clearing the cache of it first and if that does not work flash the factory images you can keep you data by only flashing system then if it still does not work flash all the imgs for data and cache ect if that does not work RMA time. nexus factory images are here:https://developers.google.com/android/nexus/images

I just started having the same problem today. Battery is fully charged, then goes to 0 instantly. Wont power up unless you plug it in. Seems to do it more when watching embedded youtube videos in chrome browser.

I have this same issue, I've tried all the "fixes" and different roms/kernals. I don't think this is the same battery issue others have reported. This happens whether I am at 100% battery or 5% and even if I plug it in, start nexus 6 up, unplug it after it's been running./charged for a while, after 30 seconds or so it will just go black and be powered off. It's the same effect if you pulled the power, since its not even going through the standard shutting down procedures like it normally would if it was just low battery.
If anyone has a fix, please let us know! I'm currently deployed so I can't even RMA the thing, had my wife send out my Nexus 5, so I'll switch to that until I get back to the states.

RMA. Probably related to the battery issues.

Had this exact issues on my nexus 4. Turned out the battery was swollen and damaged. I was told NOT to use it on charge as it could possible blow/leak and get a new one. Like a fool I brought a cheap but supposedly a real replacement but it lasted 2 charging cycles before stopping holding any charge I put in. By this time it had been opened up more times than a crack head whore so I bit the bullet and brought/upgraded to a nexus 6. What a Great phone. but..... Yeah, likely battery issue. FYI I got signal loss moments before it died

Power off your phone.Press and hold the Power and Volume Down buttons. This will put the phone in fastboot.Use the Volume buttons to scroll through the menu until you see "Bootloader logs"Press and hold the power key for a long time (7+ seconds) until the phone reboots.
