Nexus 7 won't charge. Possibly fried.
My nexus did the same thing, it has to do with the power save feature. I googled the issue, after charging with the original charger for about an hour . I used the hold the power button, for a good 2-......

Connecting your N7 to your PC and hearing only a ding means you're probably in APX mode with a corrupted bootloader. Download the universal APX drivers to confirm this. Unfortunately, if you're in APX mode without previously-generated nvflash blob files, you're up the creek without a paddle. No one has recovered an NVidea device from a corrupted bootloader without nvflash, and darn few have done it, period!
I had to replace my N7's motherboard to get it wotking again.

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

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.
Totally new here. got my nexus 7(2012) since nov 2012. This morning, I was chatting with friends and my device suddenly froze for 10 mins. i couldnt wait long so i restarted it by holding the power button. now it won't open even if i did the power + volume keys, nothing appears. even when i plug it in the wall charger or on my pc and laptop. still no charging logo or any indication it was on and my laptop says installing new device but always ends up failing so i cant back up my files from my device. I'm not a techy person so i made absolute no effort to root my device. just chatting and some occasional gaming. Please help can't afford to buy a new device for a long while
*btw its a 32gb nexus 7(2012). not sure if this additional info is helpful or not.
Do you get any sort of screen when you try to turn it on ? I.E. do you see the Google logo for a few seconds? Or do you see nothing?
My guess is with a hardware failure or your battery has come loose. When my battery becomes unplugged, I will see the Google logo and then a bunch of funky colors and it will reboot constantly when plugged in. It dies if unplugged, and It also turns on the second it is plugged in.
So if you suspect the battery, there are videos on YouTube to walk you through popping the back off along with pushing the battery back in. I used black electrical tape to hold my battery in place better once I confirmed that was what my problem was.

I would check to see if the battery connection came loose. Its an easy fix to try and was your tablet overly hot or any bulging?

i am so sorry for not replying. i know its too late now because i was asking this info on another thread. i i already tried removing and reinserting the battery on my device.
the nature of my device is that its all black screen. even when you charge it, theres no charging animation that shows or any backlight. its like its really off without anything plugged.
when i plugged it in the pc under device manager, it says apx mode. kinda depressed cuz i think the device is already dead cuz i cant even do the power button + vol down thingie :crying:.
Try pressing and holding in the power button for a long time, up to a minute.

My Nexus 7(2012) 16 gb appears dead. Was on CM11 with TWRP recovery.
Here's what happened :
I was using my N7, the screen froze for a second while scrolling on the browser.
After that a dead black line appeared permanently in the middle of the screen(horizontal).
I figured it might just be the case of dead pixels.
I continued using it like that only.
After a few weeks of usage, now the device won't power up at all.
When i connect to the wall charger, i just get a back light. No display. Nothing.
I tried booting into recovery, but nothing appears on the screen.
I kept it charging for few hours, but no luck.
It only flickers when connected to charger. Disconnecting the charger causes no activity what so ever on the device.
Nothing happens if i connect it to computer via usb.
Any solutions i can try?
Press & Hold the power button for at least 10 seconds while plugged into a power source. If no signs of life after completing the above step my first thought would be a faulty board..
Its just a black blank screen.

Well, I would hate to be the bearer of bad news but it appears your device had a critical failure and is now dead... Obvious answer right? HaHa
RIP Nexus :crying:
You can always try and leave it to charger for a day and see if you get some life to your nexus. I had similiar thing with my nexus, I was actually booting new ROM and then it did some flickering and got blacked out. After connecting to charger nothing happened, just random flickering. I was able to recover and get it back in bussiness when I woke up next morning (it had been charging over night). This was almost a year ago and atm I'm writing this with the same particular device. So give it a shot again, you might still get it back to work. Also you could try to boot the device to fastboot mode by pressing power+volume buttons at the same time for a while. Good luck, let me know if you were able to get it boot&work again!
You could also try popping the back off and make sure the ribbon cables for the display are seated properly. While your there check the battery cable.
Hi there
Apologies in advance if someone already posted this, but Im too tired of searching more!
Well, long story short.
My brother got me to root a nexus 7 2012 model.
As I tried, I found out it was already rooted. So started to Unroot+Stock it using WugFresh Nexus toolkit.
During the process, it stopped giving updates and the N7 was in Bootloader.
I tried booting it up but it would say 'Boot failed' and bring me back to to bootlader. I tried several times before powering it off.
Now the N7 does not turn on.
I have tried all the button combinations and timings up to 1 minute.
Even leaving it on charge.
HALEP BOLEEZE! (Help please!)

Just switched the batteries with my fully working Nexus 7, results:
My N7 turns on perfectly fine and charges with own battery.
My N7 with her battery did not turn on or charge
Her N7 with my battery did not turn on or charges.
When I put my battery back into mine, it turns on right away - no problems.
I guess her tablet is as good as dead?
If the tablet won't fire up with a known good battery, it's likely toast. You could try swapping the motherboard as well, in case the display is dead. If the motherboard from the dead tablet works in yours then you know where the second problem is.
I have had to reseat my USB daughterboard a few times when dealing with charging issues, but that wouldn't explain the refusal to start when supplied with a fully charged battery.

Dear XDA,
So I rooted my Asus Nexus 7 back when I got it with cyogenmod back in the day. It stopped working due to it dying and would not charge. So after a miracle and being plugged in for three days it would work. Now when its battery died it would not power on or charge at all. If I plug it in to the charger, my screen shows nothing but I can see the screen backlight so it is doing something. If I try to open the bootloader with the PWR and the volume rockers pressed the screen would flicker but won't show the android mascott with the gear's at all!! I was planning on upgrading to an unoffcial andriod 6.0 rom and run some linux on it. Is my device really dead?
It could be the battery reached its end of life or an I eternal short happened in it. I had a droid 4 that did the exact same thing. The bootloader checks the state of the battery and won't go past initializing the screen if it detects an issue
