[Q] Nexus 10 wont turn on.

I placed my nexus 10 on charging yesterday, and after a while (2-4 hours later) when i came back, i found the device to be turned off, I tried the power button in all the combination with volume buttons, but still no luck (even held the power button for 3mins) I searched online, and couldnt find any help on other forums. Some said to keep it on charging overnight and then try powering it up. But still no luck.
I dont get any notification when i connect it to charger, although when i press the power button while connected the screen lights up, and battery charging sign shows up.
Any help would be greatly appreciated.

So you cannot even get to the recovery?
You ether over charged it (very unlikely to happen) or you have a faulty N10.

No, can't even get to recovery. But i have been using the device for over two months now, nothing like this ever happened. What about the charging sign when i press the power button. It might be some kind of a sleep mode or something, no?

Could be a bootloader corruption, software issue, hardware issue or some part of the hardware "thinks" that it is still on when it is not causing it to not switch on.
Have you noticed any issues before it just came off like extreme overheating?

Well, yes the tablet was getting overheated after a long session of hd videos, or games, but that use to happen all the times.

I believe this is normally called a "Sleep of Death" or sometimes "screen off death". Hold power + vol up + vol down at the same time for 5 seconds and you should boot into fastboot. From there hit the power button to turn the tablet on. Then go about finding a better ROM/kernel combo that doesnt give you this problem.

You just need to press power and volume down to enter the bootloader.

Try press and holding the power button for around 10 seconds and then try powering it up again.

Are you using the charger/cable that came with your device?

Its working.
Weird how it was taking any input from the power button though. I kept the tablet on charging over night and i tried turning it on in the morning and it worked.
Thank you all.

I've had my Nexus 10 for less than a week, and this morning I encountered this problem. I was working on setting up syncing through an app called FolderSync and SugarSync. Syncing of one of the folders seemed to go into a loop. The device locked up completely a couple times. I got the process running again and left it running while I went for a workout. When I came back no way could I get it turned on.
I had tried all the things suggested here before checking here for help. I'll try your "solution" of leaving the device on charge overnight. If I can't get it going tomorrow morning I'll return it to Staples, where I bought it.
I have an iPad and have never encountered anything even close to these problems. Bought the Nexus 10 specifically to run the Vim Touch app for Android. The only Vim app for the iPad is horribly crippled.
Sounds like this thread pretty much exhausted the possibilities by the time epicbearman discovered his "solution," but if by chance anyone has any further suggestions I would be grateful.
Thanks,
Eric Weir

I had the exact problem as the OP and none of my chargers worked. I then googled and found someone that said to try to charge via their PC USB instead of the wall charger. I left it plugged into the USB for a couple of hours and the charge went to 4% ( so it must have been very dead ) and all is well.

I charged it via the usb charger, and connected it to my pc overnight. Try doing that.

Take off the back and disconnect the battery and reconnect it

Thanks. If I'd gotten this in time, I suspect it would've worked. But when I couldn't get it started after trying everything else and leaving it on charge overnight, I returned it to Staples.
Will order a Nexus 7 from Google. If I can get Vim Touch running successfully---my reason for wanting an Android tablet---and I find the screen to small for heavy writing---I want to get by with a soft keyboard---I'll order another 10 and give the 7 to my daughter.
Thanks again,

[SOLVED] Help - Brand new N7 having boot issues

Hacking noob here. As in never. Sorry if this is "yet another annoying noob" issue.
I just got an N7 today and I'm having boot issues. I was able to use the device initially, I got it setup and it charged to 100% earlier. Then I did my first shutdown in order to investigate the bootloader. Since then it has been difficult to get it to power on.
The device is brand new, stock, and nothing done to it, other than user setup, and USB Debugging has been enabled. And I haven't dropped it or gotten it wet or dusty or anything fail you might be thinking of. No crazy apps, not rooting ,etc.
Reading up, it sounds like I need to power off the device, then simultaneously press Vol Up, Vol Down and Power (for some amount of time) in order to get into the bootloader /recovery menu.
This does not happen. Nothing happens.
So I tried to power the device back on. It doesn't.
I plug in the USB cable and I don't see the charging icon appear.
I notice a possible discoloration near the usb port, which could simply be the spot where the notification led is, but there is a visible "spot" that can be seen there. Wondering if this is an indicated that something is fried?
After messing around with cables and random button pressing I have gotten it to boot a couple of times, and seen the charge icon a couple of times, but I'm starting to suspect that this device is effectively DOA. Its been charged sufficiently (>60%) ever since I got it.
1. Anyone have any advice on this? I have no plans to wipe the device, I wanted to actually investigate sideloading the OTA. Answer - Ignore this.
2. Am I missing something? Is there a different/specific order of operations to start it? Answer - Bobos will fail.
3. Does it matter if USB power is connected while trying any of this? I've tried 3 different sources. And none provide a consistent state. Answer - No.
4. Can anyone else confirm this "discoloration" is visible at this spot? (halfway between the bottom center and the display area) Answer - Its just the notification led.
UPDATE: Turns out that pressing all 3 buttons causes a portal to another planet to open over Manhattan. Do not do this.
Instead simply press Power + VolDown to get to the bootloader.

I expect you have a defective device. However, you might just be doing weird things with your buttons.
To get to the bootloader, you just need to hold down the power button and volume down button. You don't need to have the microUSB cord plugged in.
For simply booting up the system: there have been times when I've had to hold the power button down for a while in order to get the device to boot up.

You need to hold the power button down a few seconds to turn on.
Boot loader is Power+VolDown
The discoloration is the notification led.

Thanks for the replies! I was able to finally get into the bootloader menu by following xdhall's instructions. And from there, into Recovery. Since using this method I'm not having any power on issues. It may be a "bug" in how it registers button presses, because it definitely isn't acceptable to have my experience occur (no usb charge, etc)
On to trying to update to 4.4 via the OTA recovery method. Google can't stop me now.
Thanks to sfhub for speaking to the discoloration. I really wasn't sure if I saw it before this issue started. Better to panic and ask, then assume and fail.
Oh yeah, don't press down all 3 buttons for 10 seconds from power off, it does wierd things.

I have issues getting it to power on once in a while too. Have to leave it for a while or put it on charge for a while and then the power button works.

If you get the blinking LEDs, that is because the power is drained too low.

No blinking LED,just doesn't boot always at any battery level whatsoever. No issues with the buttons, they work fine when on. Untouched and locked system.

I had that too...returned it.
It was totally random...and would shut down by itself at random even though I charged it recently. I think it's an issue w/ the battery level sensor because to get it to boot, I'd have to plug it in for 15min, then power it up...
My old N7 2012 never had that quirk

I'm glad you were able to solve your problem with your nexus 7! I hope you enjoy it!

[Q] Can't Power On

I was using the Nexus Root Toolkit v1.7.9 to flash stock back onto the device when it hung. Went to a black screen and then refused to power on. To elaborate, it will not display a battery icon when on the charger, nor can I get the device to display anything on the screen with any button combination. No fastboot. No twrp. Nothing. The only sign of life I have gotten from it is when connecting a usb to my computer (Windows 8.1) and holding down the power button on the device, I can hear it "connect" to the computer. In device manager, it shows up as APX. It had previously been shown as a USB device that could not return an ID...or something to that effect.
Without being able to boot the device up, I am clueless as to what to do. I have tried charging it for an hour. I have tried all button combinations, along with holding them for various lengths of time. I am just out of ideas and can't seem to find anyone else experiencing this exact issue.
Is anybody with more experience able to point me in the right direction?
Thanks in advance.

This happened to me awhile ago. When I first started to read about this issue it was that the battery becomes lose causing this issue. Another is just letting it sit idle for so long and no matter what the battery level it would cause this as well. Sorry can't remember all the technical stuff on that one.
I eventually contacted asus and sent it back. About two weeks later I was sent a new one.

Nexus 7 wont charge or boot up

Some time ago my nexus 7 powered off and didn't boot back or show the charging animation.
I tried Google solutions and non worked, I looked all over the internet for solution tried tons of stuff but nothing worked.
I tried charging it for nights tried holding power button for minutes, volume buttons for minutes, power button & volume button for minutes.
For some reason when connecting it to the computer the computer does recognize it as unknown device.
Sorry if its a repost.
Please help.
If it is matter i own a nexus 7 3g 32gb.

If you connect it to your pc, can you see it with fastboot?

I cant get into fastboot i cant even see the charging animation

I don't think you can do much about it than. Send it back to Asus for repair.

Try to get into recovery
Sent from my Nexus 7 using XDA Premium 4 mobile app

I have this exact problem. The tablet got worse and worse. I am fairly certain the usb port has faulted some how.

There is a thread here about charging problems and suggested fixes....
https://productforums.google.com/forum/m/#!msg/nexus/wrTqHYhS-Vw/aeh9wYrQYxUJ
While there is no definitive fix, the one that helped me.....i did not ever get completely flat battery like yourselves.... was charging through the pogo pins. The docks do this, i dont have a dock but managed to charge through a diy solution.

Nexus 7 Dead (as in, totally dead!)

Hey guys, I signed up here because I'm desperate for help!
To cut a long story short, I upgraded my N7 (wifi 2012 model) from 4.4.4 to 5.1.1 which was an awful idea as performance was through the floor. So I used the ADB tools to flash and downgrade back to a stock 4.4.4 image from the google repository.
Unfortunately, after flashing I tries to get to the recovery mode (was on the boot loader) and it said "error", wouldn't let me go any further and just kept me in the boot loader menu. I rebooted the device thinking it might have just needed a gentle shove, but it didn't reboot...it turned off after using the power off command.
Now when I "try" to turn the device on I get a black screen and nothing else. To confirm, this isn't the usual battery related "black screen" with grey static and the enabled backlight caused by long term discharge. The screen is totally black, no matter what key combination I use there is no visual response. The only time I can generally see any sign of life is when It's plugged into my laptop - windows plays the "new device detected" chime, but ADB can't see it and about 90% of the time windows states there was a device error. At this present moment the device is powered on (again, no visual sign) just a chime and an active driver showing in devmgmr for "Android ADB Interface".
ADB - Any attempt to use ADB fails and shows "no device found / connected", I've tried multiple solutions such as the nexus root kit but they all have the same issue, they just can't talk to the device. I know it's not the laptop at fault because it was detected fine multiple times prior to flashing it?
There is something alive in the device in terms of powering it off and off as holding the power+vol down button does do enough to trigger the windows chime to indicate it's powered on, but windows can't do anything with it at all. Note the device was 95% charged during the flash so it's not like it crashed mid way.
Any help would be appreciated, it'd be a shame to bin it
Thanks
Lawrence

Take the back off and disconnect the battery. Press the power button to discharge any leftover charge. Plug back in the battery, then try powering up in bootloader mode.

Hi Psiphi,
I did as you suggested, took the case off and disconnected the battery cable - pressed and held the power button in different combinations to make sure it discharges any remaining power.
Sadly, no change - any attempt to power it on results in the same lack of response
Anything else to try?
Thanks

You might try forcing a flash using the Nexus Root Toolkit, but otherwise I am out of ideas short of buying new hardware.

I agree use nexus toolkit, use the force flash mode... I recovered mine about 6 months ago it was dead... Nothing worked...
