TF not waking up. Sleep of Death?

Hi for some reason I cant get my TF to turn on! It was working fine all day. I left work and placed the TF in sleep mode (hitting the button) When I got home about 15 mins later, I hit the power button and nothing. I read about the Sleep of Death but this is the first time Ive had this. I try holding onto the power button for 10 seconds and then releasing it and then held it for another few seconds and nothing. I even try holding the power button for one mins and then releasing it and hitting it again and nothing. I had bout 35% battery life before heading home.
I plug it into my notebook and i get the prompt the auto play message on windows 7. double click on the TF TF101 icon and I cant see any folders. On the asus sync program it tells me no device is found. While its plugged into the notebook I held onto the power button and I get that sound coming from windows (usb sound) then I get a sound coming out of my TF and the auto play message pop up. I cant even get it to go into recovery mode (vol down + power) I am on 3.1 leaked and no root. Any other suggestion before I call Asus. Thanks

Try charging it for a few hours, the battery might've drained due to some apps keeping wifi on for the whole time (using WakeLock)

Thanks. Doing it right now. Its weird when I have it plug into my notebook. While holding the power button it will disconnect from my notebook (no longer visible in my computer) then pressing the power button again its pop up with the auto play message and i get a sound from the speakers of the TF...one of those default sound on the TF. (new email alert sound) but the screen is still black. I also trying hooking it up to my TV to see if I could get a picture and no...
OKAY got a picture now with the hdmi input but no picture on the TF. I have the pattern lock screen. do i disable it? I am able tole move around but trying to find out how to disable the pattern lock screen.

yea maybe you just drained it too much. i bet a long chargewill remedy this

I am at 50% and still no picture on the tf. Now when I try to enter my pattern for the lock screen its turning red not green like before....wtf reboot and still cant get in.

Just to share, a similar but less drastic thing happened when i got mine.
Tried it at the shop for about 5 minutes just to check everything worked fine. Packed it back into the box and took it home. About half a day later, at night when i officially unboxed it,it refused to turn on. no sound, no lights, nada. when i turned it off at the store, it still showed about 50+% battery remaining.
Same thing if i attached it to the dock.
So i left it stuck into the dock (just so i can confirm that it's charging) and left it to charge for about 15mins (while worrying that i might have a DOA TF).
The light was a steady amber from the get go, meaning >95% charge.
Anyway, left it to charge for about 15-20 minutes while trying every combination i could think of, short, 10 seconds, 1 min, more than 1 mins..
Long story short, after a while, it booted up with a 10second press of the power button.... left it to charge overnight (>8 hrs first charge) and it's been fine since.
Good luck with yours.

Okay reboot again. and its not take my pattern for the lock screen. touch the first circle and its red. and it tells me to try again...wtf....normally its turn green on the circle (the first one) now its red.

Looks like my screen is dead....smh.. I am able to see the lock screen via hdmi but its not taking my lock pattern. Every circle I hit turns red (error I guess) I dont know what else to do. I try doing a factory reset (volume down and power button at the same time) but I cant get a display on my tv when i am trying to access his mode. I called Asus and got a RMA... Just wondering do i need to send in the wall charger and usb cable too? Before sending it in does anyone know what else I could do??? Thanks

Nexus 10 won't boot after charging

Hi guys,
My battery went completely dead, left it to charge over night, now wont boot at all. If its plugged into the charger and I hold the power button the full battery symbol (black and white) shows for about 2 seconds and then goes off for about the same time then reapers. Any ideas?
Device status:
- Stock rom
- boot loader unlocked
- non-rooted
I've tried :
- Hold power for 30 seconds to a minute
- Hold power + volume buttons for 30 seconds to a minute
- no response form my computer when its plugged in
- no response when trying to boot into fast boot
I am aware this has already been asked. I've tried the other threads but no luck
EDIT
I got mine to boot. I have literally no idea how, I just tried the power button again and it burst into life, although the battery was empty.
I think this could be due to not letting the battery die enough. I normally let my phone (HTC One) so completely flat every month or so but i've never done it for the Nexus 10.

The same problem please help

Serious bump. Ive tried all of these methods, but it just shows the charge icon when plugged in. This is the first time for me that it wouldnt just turn on after going into that sleep state. Charged over night.

I think this is the same issue that many (or a few) people are having. Mine, for example, will be at 100% charge. Then, sometime in the day (without using it) it will die. It will not power on. When I plug it into a charger, it will show the charge indicator on the screen, and I can get it to power on 50% of the time right away by holding down the power button for about 5-10 seconds.
When it boots up, the android tells me it is at 0% battery. If I leave it plugged in it will usually show 100% again after a short period of time, but until then, if i unplug it, the tablet powers right off.

Here is a pretty good thread to see the issue.

Here's a question for you:
Watch your battery life. At any point, does it begin NOT draining? Such as remaining at 60% for 2-3 hours during usage? If so, you may have a defective motherboard and require warranty replacement, as that was one of my symptoms.

Stupid stupid mistake!

I think I have fried my Nexus 7.... didn't even think about what I did how stupid am I....
I decided to wire up a Hella connector to a USB cable the idea being to plug it into my phone for charging on the road... I then had a not so smart idea to use my OTG cable to connect the USB A connector to my Nexus 7 to see if it worked...
Nexus 7 booted past the bootloader and then nothing.... I realised then how stupid I had just been...and still nothing...
Presumably I've run a shed load of power down one of the data line..... what a fool.....
ARGH!!!!!!! anything I can possibly do to salvage it.... please!! :crying::crying::crying:

you could try something ASUS support told me, press all buttons (volume + & -, power) for 30 seconds, and if it won't boot after that, you should get a RMA

Going the RMA route would be costly. If it is dead, he'd be better off just bring a new N7.

Thanks for the suggestion but no it hasn't worked...
I've had the N7 plugged into the charger for the last 30 minutes or so and when I went back to it the screen backlight was on slightly (you can see if you look at the screen from the side)... but the whole unit was really really hot... I've obviously disconnected it but now can't get the thing to turn off, if I hold down the power button the screen flicks off but then back on.

I would think that "broken display” units on eBay/CL probably have working mobos and batteries, as the owners are trying to dump them because of the broken screen. But, buying used is a crap shoot.
Nice that Google is selling N7s at cost (or even a loss) - but it does mean that any oem component replacements will be a significant fraction of the original price.

I was reading in Play Books when my N7 shut down due to low battery. I plugged it in and it wouldn't charge or boot and I noticed a faint light bleed and faint dots streaming from right to left on the display. I tried things like holding the power button for 30 seconds to reset, holding vol down and power to try to get to recovery, but it wouldn't take. Finally, with it plugged in, I held down the power button for just about 10 seconds and backlight and dots stopped. A few seconds later without pressing anything, it booted up. It would start to charge, but if the screen timed out, I was back to the earlier state and it wouldn't come on. So I got it started again and immediately went to developer options and checked Stay Awake while plugged in. Eventually the charge built up and I'm back to normal, at least my N7 is normal. I only mention this because the OP talked about the faint backlight and it may be worth trying.

A standard hella charger outputs 5V at 2A which is the same as your N7 original wall charger.
I doubt your problem came from the charger, it might be softbrick at an unfortunately moment.
I came across a similar problem when i was editing a custom kernel.
If you tried every method to shut down the device and failed do the following:
1. Open the case (it's quite easy to open with a plastic card)
http://www.ifixit.com/Guide/Installing+Nexus+7+Battery/9895/1
2. Unplug the battery and hold the power button 30 seconds (with the battery detached)
3. Let it soak for 10 minutes
4. Reconnect the battery and close the lid.
5. Put your nexus 7 in the wall charger, and you should see the battery bar on the screen.
After that, let it charge a few minutes and boot the device.

[Q] Need Help: My Nexus 7 does not turn on and no response at all

My nexus 7 (2012 3G) became unresponsive while I am using it so I pressed the power button for several seconds to restart it. It went off and since then it did not respond to anything.
It is an unrooted nexus 7 using the latest stock android version (4.4.2). I got the the update OTA several months ago and it worked well since then.
I tried the power button for more than 30 seconds, the volume down + power button together for several seconds and the 3 buttons simultaneously (2 volume buttons and power) for several seconds and it did not respond.
I connected it to charger (its original charger but not the original cable. I use this cable since the original one stopped working) for several hours and it did not show any sign of charging and still no response for any buttons.
I connected it to PC and it shows APX mode in device manager and still no response to any button combination while connected to PC. The only thing that happens is that after pressing the power button for around 10 seconds while connected to PC the device gets disconnected and reconnected instantly to PC but no signs of life at all on N7.
I even opened the back of the device to manually disconnect and reconnect battery and nothing happened.
Can anyone help me with this? Is there anyway to get the nexus back to life?
Thanks in advance.

There is a whole tread about this issue on here.
Same thing happened to me.
I could not revive it with all the how to post i read . So i sent my in for service . I bought the Square trade warranty . I sent them a request to tell me exactly what part they replaced or how they got it back on.
If they tell me i will Reply with a answer. I got it back two days ago.

Hi, tfar...
APX mode is suggestive of a dead, corrupted or erased bootloader.
For more details, see my earlier post here, where somebody seems to have had a similar problem.
If your bootloader is truly 'dead', then a return to manufacturer under warranty, is your only real option.
Rgrds,
Ged.

They told me they Replaced the Main Board and Battery at the Repair Facility..Not really sure because of how vague they were about it.
It was same as some of the other post pc would sometimes see it as apx device and sometimes see it as descriptor not found or something like that.
Now its Working perfect . I do believe this is happening when you let the devices battery totally drain and not charging it before you power it on.
Just my opinion.

Nexus 7 2012 problems

Hi all,
I'm struggling with getting my 2012 Nexus 7 to start and hope someone out there can help!
I think I may have let the battery become discharged, but anyway here are the symptoms:
Connected the power lead and the tablet initially showed the empty battery icon but then started to flash up the word Google but does not boot up. Left it connected for a couple of hours. Still no joy.
Did a bit of internet research in an attempt to reset the tablet via the button combinations.
With the power lead disconnected, holding on/off plus volume+ together eventually gives a blank screen and from there holding on/off plus vol- gives the Android figure with its belly open. Hitting vol+ scrolls thru the four options of start / power off / recovery mode / restart bootloader, however when I select 'recovery mode' and press the on/off button instead of showing the Android with a red triangle it simply goes back to flashing 'Google'.
From there, if I press and hold on/off and vol- for several seconds the screen gives a momentary blue flash and then the fours 'dancing blobs' appear, eventually to be replaced with the flashing 'Google' but still no boot up.
If I connect the power lead although I can get the initial Android figure, I cannot scoll for any of the options.
All of this sounds like a major fault, but funnily enough yesterday evening I left the tablet with a blank screen and disconnected only to find this morning that it had booted and had all my apps showing, all of which appeared to be working properly. so I connected the charge lead and it said I had 17% battery remaining however the battery charge graph showed a number of major gaps and also showed the wrong date (2 days behind). So I connected the power lead and left it for 10 mins to find that the charge state hadn't moved but also that the screen brightness was reduced as if it wasn't connected. So I unplugged and then re-plugged the power lead and it said it was optimising 1 of 2 apps then the screen brightness returned to full, any appearing to function ok.
So left if for around 30 mins at which point the charge had gone up to 21% and I decided to try switching it off. Bad move!! Instead of booting up it simply returned to the flashing 'Google'. Which is about where the story started.
I've had the back off and the battery connector hasn't shifted, but one thing I did notice is that there is a fourth key switch below the vol- switch but without a hole in the cover to actuate it when assembled. Is this part of the button-press combination to restore factory seetings with the back off ??
If anyone out there can make sense of what the tablet is doing, I'd love to hear from you!!
Mike
