Hello,
Last week I was using my phone as usual, I put it on my desk for about 5 minutes and when I came back it had turned off. I tried putting it on charge but the orange led doesn't show any activity. The phone doesn't turn on and doesn't do anything. I tried booting it on recovery but that didn't do anything else. I also took off the battery and put it back several times.
Help!

try cleaning the battery contacts and also the usb contacts, i had mine where it wouldnt charge all night and died and it was just dust caught on the +5v pin of the usb connector.
There is lost of dust in the usb connector, you should try to clean it. The battery might be dead, you can try to buy another one but...
That didn't work. (does the led light turn on if there is no battery in the phone or it must have one inside?)
It does need to have one inside to lit the led
If you know someone with a DHD, you should try his battery. But your phone is probably dead... Fortunatelly, the GS3 will be announced soon !
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.

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.

I am freaking out. I just plugged it in to charge it (not the charger that it came with) and it was only plugged in for a few minutes. I unplugged it and turned it on and now my screen looks like a crappy television from the '60s. It's all lined and flickering and horrible! What did I do! Did I destroy it??
EDIT: Turns out it was the charger that it came with, but I had plugged the micro-usb cable into an extension cable to increase the length. Could this have been the issue somehow?
I had this happen day 1 using the provided cable and charger. I turned it off and back on and never saw the problem again.
I had this same thing happen with my N7 recently.
I was reading something, the power hit 4% and the thing shut down. I tried turning it back on, but it refused. I plugged it in to charge it and tried to turn it on again and after a couple of tries, it came on. I must have knocked the power cable loose, but the screen went all white and black stripes, just like what you are describing. It took a bit to shut it off, but it eventually did. I plugged it back in, waited for about a minute, and the charging icon popped up. Unfortunately, the screen looked like crap. It looked like huge odd patterns were burnt into the screen. I was really worried. I turned the screen off again, tried to take my mind off of the situation for a while (maybe an hour or so) and came back and everything was normal. I have no idea what happened, but give it some time before you freak out; it may be fine.
You're right, it does seem better now. I plugged it in to charge from the standard charger like it's supposed to and turned it off for half an hour. Seems OK now. Thanks for the support, fellas. Why on earth does it do that? Should I know more about this in case it could be permanent at some point?

Pretty self explanatory. It was dead for a couple of days, I put it on the charger for almost the whole day, now I get no picture, but the backlight is on when I hold the power down a minute. I bought it at walmart, doubt I have the receipt, and didn't get any extended warranty. Is there a way to fix this issue?
I've got the same issue. I was playing Tupsu, when suddenly my n7 rebooted and there was no picture, just semi-strong backlight. When the tablet died, the battery was about 45-50% and I was charging it through notebook's usb port (original n7 cable). I tried to turn it off, but pressing and holding the power button only made it reboot once again (i assume it was rebooting, since the backlight was turning off and on in a second). I've tried it many times, with tablet plugged into wall/usb charger, and even with the power+volume up/down combination, it would still behave the same way. However sometimes after rebooting there was not only backlight, but also thin, mostly white, horizontal lines, appearing in random places of the screen (appearing and disappearing after like 50-100 ms). It would stop only after a reboot, and happened every 5-10 reboots.
I've decided to let the battery die to see if it changes something, and as you may guess - it didn't. It died estimately after 2 or 3 hours. Now it's all the same, except for when I plug it to the charger, there's only a very low backlight (still no picture) and it's blinking... It also makes this continuous "electricity-related" (sorry, I don't know what's the word to call it ) sound. After I press the power on, or let it charge for 1-2 minutes it boots up, and there's just a semi-strong backlight, like earlier.
It's a refurbished 8gb n7, which I got 5 days ago from the polish Asus online store. Oh, and the speakers weren't 100% fine, if it changes something. They were fine at first, but after i plugged headphones in and out, they were making cracking sounds when the volume was over 50% or something like that. Is there any hope I can fix it myself?
edit: the android ver. is 4.2.2, not rooted
the device is getting warm on the left side when being charged, or just turned on...
Have you tried pulling the battery for a couple of minutes?

Nope, i don't want to mess with the hardware since i've bought it only few days ago... I'm afraid it may leave some traces of being opened, i'm not willing to take the risk.
You won't leave a trace pulling the battery. Just use a guitar pick or credit card and run it round, the back comes off very easily.
Sent from my GT-I9000 using Tapatalk 2
Yeah that is definitely worth a shot. Just pull the battery.
Ok, I did it.
Didn't change a thing >:[
btw. I didn't actually pulled off the battery, i've just disconnected it - it doesn't make a difference, does it? and another thing - the backlight was turning on immediately after connecting the battery... with these randomly popping horizontal lines.
I've got this too!

I've got this too! Pulling the battery does nothing. Last time it just fixed itself, now nothing.
Worried I'll have to take mine back.
How did that 'fixing itself' happened to you if i may ask? And how long did it last?
Your tablet has gone into sleep mode to protect the battery from further damage due to its low level of charge. What you're seeing is by design, as complete discharge of a lithium based battery is bad for it. You should never, ever, let it sit dead for a couple days. If you do discharge it to the point of shutdown again, immediately put some sort of charge on it, as waiting to long will cause the battery's protection circuit to fail completely. Best practice is to not let your device go to the point of shutdown, but rather to plug it in when not in use. Your battery will have a longer lifespan.
Plug your N7 into the charger and immediately press power and volume down to get into the bootloader. Once there, use the volume key to scroll to Power Off Device and then press the power button. After it powers off, unplug it and then plug it back in. It should then charge normally.
You seem not to have read my posts at all. When it happened, the battery was about 45-50% and it was plugged into the laptop's usb port. It suddenly rebooted and there was no more picture, just the backlight - and it lasted for like 2-3 hours (maybe even longer)! Can a completely discharged battery power the backlight for this long? After it turned off at last, i put it on charge and i've tried the power+volume method and it didn't do anything (btw. i already wrote about it)... then i let it charge for like 5-6 hours and it didn't change anything except for the fact, that the battery was evidently charged, because the backlight again lasted for few hours.

Actually, I was addressing the OP without realizing that this was a zombie thread.
To answer your question though... yes, when in sleep mode the battery can still turn on the backlight and keep it powered for some time due to the low power requirement of a black screen. Many users that have found themselves in sleep mode actually have their tablets enter into a prolonged cycle of bootloops. From the sounds of it, your device seems to have, for reasons unknown, put itself to sleep.
Anyway, I digress... I know you've stated you've tried various combinations of the power and volume keys. Have you attempted holding all three buttons for approximately 30-40 seconds while the tablet is plugged in? If it that will force it into the bootloader, you can follow the steps that I posted to get it up and running again. If not, then it seems your best available option is to seek an RMA from ASUS. Given your speaker issue, I'd send it back regardless- you shouldn't be expected to deal with battery and speaker issues after only five days.

I woke up this morning after realizing my alarm on my phone didnt go off. When I went to check my phone, I found that it won't turn on.
I tried the Volume Down + Power for 15 seconds, 30 seconds, and 1 minute. I also tried safemode Volume Up + Power for 15 sec, 30 sec, and 1 minute.
Tried connecting to the computer to see if I could adb reboot it but the phone isnt being detected by adb. I can hear it connecting and disconnecting constantly from windows.
I put the phone on the charger last night at about 60% charge, so it should have had enough battery to sit unused for a few hours but it was only about 6 hours later that I noticed it wouldn't turn on.
Right now I am just hoping the battery bugged out and drained so the phone is sitting on the charger charging up but there's no signs of life. My phone has been fine for a month with the September patches and fine before that. I havent taken the october patch yet.
My phone is a little bit over 2 months old.
What else can I do and what would have caused the phone to suddenly not turn on?
Update: Phone has been charging for about 2.5 hours. It is charging at a constant 11mA (0.11A) and has taken in about 220mA. The screen still hasn't came back on. Email sent to Essential a few hours ago, no reply yet.

Phones purchased in the US come with a 1 year warranty.
I would assume Mexico would get a similar warranty.
You will need your original proof of purchase.
Contact Essential and explain your situation, they will probably be able to come up with a solution for you.

I thank you for your attention, I let it be completely discharged and I have connected it to charge right now and on ... I am happy !!!!
Same problem here, actually my phone was on but screen would not come out of wake. Screen would brighten slightly when combination of buttons pushed,
This happened to me after about two weeks of use, first time it happened I was able to make it come alive by playing with buttons. Than about a week later after having it charging it would not become active.
Emailed Essential with problem, they sent out a replacement unit.
First time I had problem, I was on PIE non rooted, when it finally died I was stock rooted PIE. I don't think rooting had anything to do with problem since it happened even before root. Network Sprint
good morning to all, I hope and can help my team last night when I was watching videos after 2 hours the screen froze so I decided to force a reboot with which I thought the problem would be solved, but to my surprise it was not like that, the phone when turning on did not give imangen only the screen cleared so I knew it had been turned on, but never gave an image, I let it completely discharged thinking that with that it would be fixed and nothing, I put it on and when I turn on the same thing happens it clears the screen but it does not give an image, try the button convention and nothing that solves it, someone has had the same problem? the phone and try tentadilla unlock and put music in spotify so the touch and sound work, also frame and enter calls as well as calls by messenger! help
