Ok so last night my battery died, so I plugged it in over night and in the morning my alarm goes of, I try to open up my screen to stop it but my screen just stays black!
Everything else worked, the 4 buttons responded, the volume rocker responded, etc but my screen just stays black! no matter how many times I press the unlock button(which does respond because my 4 buttons lit up when pressing,
Anyone else here that had a similar problem?
I never really overclocked or not recently
I have nightly Cyanogenmod 7 build
Screen stay black even with repeated pushes of the power button, or opening the keyboard? Try pulling the battery and rebooting.
Did you charge overnight on USB, or the wall charger. Try charging on the wall charger overnight, if you haven't already.

Thanks for your reply,
Yes even when opening the keyboard or pushing the power button numerous times, and I charged the phone with a wallcharger overnight. The phone is on actually it's the screen that just isn't working, I can push the 4 buttons(also lit up) and it vibrates, the volume rocker gives me the preview sound level thingie. Sometimes It even vibrates when I touch the screen.
It's really strange because I didn't drop him or anything.
EDIT:
Ok so suddenly, i unlock him after the 100000st reboot, and i got this, and the lines keep changing very fast... hard to explain... as there is some interference
And this happens when I press the powerbutton, then do my normal unlock gesture. If that might help for anything
No one that has any clue?
Looking like a hardware problem to me...
What's his name?

Something could have happened to the flex cable that is where the hinge is. I'd take it to a local store to get it repaired under warranty.
HELP,
yesterday, I was using my nexus 7 for normal use, wasn't playing game, just browsing with chrome. the battery was 8 percent when I last saw it. I then proceed to charge it, but the thing suddenly just shut down itself. I thought I misread the battery percentage, so I charge it anyway. about an hour later, i checked on my nexus 7, turn it on, got to the boot screen, got to the home screen, use it for about 15 minutes, and suddenly, the screen black out, it was flickering like crazy, and making some white noise ish sound. I panicked so I hold down the power button and turn it off. I turn it on again, and after about 30 seconds, the same thing happened again. I was using motley's kernel with 520 GPU, and I thought, maybe my nexus 7 cant handle the GPU OC. So I went to recovery, tried playing with recovery for about a minute or so, but the screen didn't flicker at all on the recovery. So I flashed the 484 GPU version of motley's kernel. When I reboot to system, the same thing happened again. So I thought, maybe if I restore to my old backup, it would not be like this any more. so I wipe the data, dalvik, and cache, and I restore my old backup. But the same thing happened again, only this time, after I turn it off, it make a high pitched sound.
I waited for about 6 hours, and now when I turn my nexus 7 on again, it works normally.
So, what has happened to my nexus 7?

I'd say it is the overclock. Graphic cards do some weird stuff when overclocked. You can burn up your GPU doing that and cause it to forever freak out. I always shied away from GPU overclocks.

would that cause any permanent damage?

It should be ok if you reflash back to stock rom to make all the hardware back to reset mode. A warning always given when we try to flash rom with oc created.
i also experienced this one, also received a battery warning and then suddenly screen went blank. then same weird thing happened as the one above. I'm on paranoid android rom and i'm quite sure it's not overclocked or something. Was only able to get back to normal by holding the power button for around 15-20 seconds...
Happens to me
This will happen to me a lot when my nexus 7s battery dies, I plug the tablet in and then immediately try to start it up. It will work for around 30 seconds then look like an old TV without a signal. I am on stock everything, no rooting or custom Roms (yet). I always thought it had something to do with battery calibration being off and the tablet not having enough power to run, because it always works fine when I charge it before attempting to boot.
I have also noticed that every once in a while the screen will have a vertical line of pixels flicker.
Same thing happened to me yesterday...
I got the "low battery" warning and after some time the screen started flickering in many colors and there was a weird static noise.
I pushed the on/off button, but it wouldn't turn on again. After a few minutes of charging, I could turn it on again.
This isn't normal behaviour, is it? Shouldn't the N7 perform a regular shut-down when the battery has no juice left?
I'm on the rooted stock rom btw.

I faced the same problem. I dont know when the battery might have drained out, but on starting the tab on low battery, it suddenly started showing black screen with little grains and suddenly stopped with a noise. I charged, started the tab again while charging, and the battery reading stuck at 21% even after charging for 20 mins. Within 5 mins, it happened again. Now after 35 mins of charging, I start it again, it boots normal, and now its reading the battery percentage in an incremental value (started with 22%) and now its again stuck at 23%
Is this a HW related issue? Or do you think it is more of SW related issue? If it is more towards the HW side, we better have it replaced. Mine is C70 model.

just happened to me... it may have run out of juice... didn't turn on when I tried, so I guess it did... then I put it on the charger, tried booting it, went away for a sec and when I came back I also got this black screen with some flicker and a static noise...
will now try to charge it over night before trying again...
Nexus 7/Google problems
I received my Nexus 7 on Aug 21 after hearing the rave reviews. It didn't come with app for a camera, so I downloaded one.
The camera didn't work. I re-booted it & it worked this time. Downloaded Skype - whole reason for getting the tablet - to stay in touch with family that is far away. Tried to Skype - camera wouldn't work. Rebooted - worked this time again (getting tired of having to reboot for something I want to use to work). On Sept 2, sent message to Google inquiring about camera & app I downloaded. Only response - "thank you for contacting...blah, blah, blah - check out Q&A." All along, the tablet would shut itself down & reboot randomly (battery fully charged sometimes). On Sept 13, I shut it down & charged it. After a full charge, I tried to power it back on. Tried again several times that night & then the next morning. Called Google (who I bought it from). Told them I didn't want a piece of junk that wouldn't work. He told me it was past my remorse period. (The only remorse I have is buying their piece of crap instead of a reputable one.) I finally did get it to come back on, but camera hasn’t work since even after a complete factory reset. Any way – in order to get this one fixed, I have to “buy” a new one, then send back the old one & be reimbursed. Is this a legitimate business practice?
hi,
since today i have the same issue. did nothing special, just swichting from g currents to chrome. stock rom, no modifications, not rooted, everything original
n7 suddenly had a black screen(battery was at 28%). nothing worked, no powerswitch(10-30 secs). when connected to original power supply and cable, it boots up.. google logo .. glowing X.. lockscreen. then, approx. 30 sec later it turns off again(screen black). usb cable still connected. after some time it comes up again.. and repeats the procedure. after some cycles it stops, and when i reconnect the usb calbe it starts over again. sometimes, before it turns black, it shows a flickering screen and sometimes fizzling sound.
any suggestions?
I had this same issue right after the 4.2 ota update, after leaving it on charge overnight it seems fine now after a couple of discharge / charge cycles
Its like after the update it was over estimating the battery level

Same thing!
I have a completely stock Nexus 7, and the EXACT same problems are happening to me too! The first couple of times it happened my tablet would reboot normaly. But now, my tablet won't boot up at all. Any suggestions on what I should do? Also, remember, I have no mods installed.
Happening to me too.My N7 shut itself down because of low battery a couple hours ago and I haven't been able to get it to boot since. When I plug it into the charger it shows a flickering screen like a tv with no signal but with less white flickers. I've tried multiple chargers and cables but I could only get it to boot up a couple times and both times it did not show that it was charging even though it was plugged in and the battery was at 0% so as soon as it boots up it shuts itself down again because of low battery.
So now I've got it on the charger, screen all a'flicker, waiting for it to get a charge but I've got a feeling its not even charging because, like I said, the few times it has booted it showed the battery at 0% and not charging.
I guess I'll try to leave it alone for a while and see if it will start up after being plugged in for a bit.
EDIT: I let it sit there and charge for about an hour or so (with the screen flickering) and I was finally able to get it booted. It said it only had 3% battery but now it seems to be charging as fast as usual.

Yup... I've let mine sit there turned off and charging over night... helped!
Just had a problem with the Nexus 7 not charging when battery was likely fully depleted. Putting a charge cable in was automatically booting the Nexus 7 up and wouldn't charge shutting down right after. Loops going on and off. What I did was plug a charge cable in and hold power+both volumes and now I believe I am charging at the bootloader screen. It stays on so I will leave it like this and if it doesn't resolve the issue I will try recovery once it is charged.
I've just started having the same issue. Has happened twice when battery gets to 8%, suddenly jumps to 0, shuts down, then after a few seconds restarts itself. Gets to home screen for a few seconds, battery showing 8, then jumps to zero, switches off and has flickering blocks on screen with static noise. This keeps repeating, only way I have found to solve it is to load into bootloader, then select power off. Device charges normally then and once charged works fine. I am unlocked and rooted but running stock 4.2.1, think I'll just have to return it for a warranty claim.
Based on what you experienced, the lesson here is your device can't handle the GPU over clock of more than 446mhz or it will do some crazy stuff.

Ok my n10 is rooted and romed with CARBON rom, no problems nothing, but today I had an email come in I looked at it set It down left the screen on a second later it just died. so I plugged it in back on it comes. later same thing almost dead checked new email, set it down screen on then death.....plugged it in again, now nothing except a flashing battery charging symbol. been charging for 10 min. tried power, power volume down, nothing....got a different cable...nothing.....my computer wont pick it up either. what do I do?????
PLEASE HELP!!!
I just had this same problem with mine; because of the strange battery issue where my battery would read 90% when it was actually empty and slow charging once it was plugged in... The resolution for me was to plug it into the charger for 5 minutes and not touch it and then try a power on.

Thanks Ill give it a go!!
Plug it in to the wall charger, not a computer. Let it sit for 30 minutes and then hold all buttons down at the same time. This should let the tablet boot now and will bring you into fastboot mode. It defaults to "Start" so just hit the power button and the tablet will boot like normal. Once you verify the tablet will boot fine, shut it down and leave it plugged into the wall charger until the tablet is charged all the way.
Dont know if it is a coincidence or not but this is the 3rd time I have heard the same story and all people were using the Carbon ROM.
Thanks guys for the feedback, definitely will be switching roms and buy the pogo charger!

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,
A few days ago my nexus 4 stopped working on me, I haven't found anyone having an identical issue so far.
Essentially, my phone does not turn on any more. I have tried holding volume down and power and this produces nothing. The only thing I can get is the red LED turning on if I hold power for about 10 seconds with it plugged in, it lingers a bit if I release power., but immediately turns off if unplugged.
It stopped working while it was plugged in and at about 60% battery, I had not had any problems with the device in the past, it worked flawlessly up to that moment. The device was running stock without any third party firmware.
Does anyone know what happened, and what I can do about it? I somewhat suspect a battery issue but I'm not sure, any help would be appreciated.
Thanks!
Hi, I'm having the exact same issue. My Nexus 4 (stock Lollipop 5.0, not rooted) died while the battery was 80% full, and the phone was charging. Shortly before it died, it restarted several times within a few hours. The phone doesn't respond to power button, neither it responds to power/volume button combination. When the phone is connected to a charger, nothing happens - no LED, no screen. If the phone is connected to a charger, and I press the power button (or power/volume) for >10s, LED starts blinking in red. The blinking pattern is weird - it blinks steadily 10 times, and gives one short blink. Any suggestions? Or any hope to get the data out?
You can possibly fix this by holding either power up or down for 15+ seconds and then connect the phone to a computer with USB. This has worked for me.
The problem might be that the battery is dying, because I've only had this problem when I've let the battery discharge, and then turned it on again. It's probably a mechanism to protect the battery from becoming "too" discharged, which might break it.
Everytime I had this in the past, I was able to fix by plugging into a very high powered charger (1000mA <) and holding down vol up + power. Eventually, it seems to trickle charge and then start. Once it's started, give it 20 seconds to get a boost then switch it on.
