My wife's Nexus 7 suddenly won't turn on... It still had juice when she went to charge it, but the next day found it was totally dead.
I've tried different chargers, tried to get to the bootloader, opened it and unplugged the battery, hooked it up via USB to my computer, etc and nothing will get this thing to power on.
Any ideas?

I mean, how long did you leave it on AC power? I know when I drain mine since coming to KitKat, it takes as long as a half an hour to respond again.

Sorry, it spent more than a day on the charger. Still nothing, cannot get it to respond at all.

If you haven't already, try holding the power button for a while until *hopefully* the Google splash appears.
A good way to tell if the device is accepting a current is by using a charger that can verify this somehow, like with an embedded LED. One like this: http://www.verizonwireless.com/accessories/rapid-wall-charger-with-6-ft-cable-for-micro-usb/
I used this for my HTC Rezound when it still worked to make sure it was taking a charge because it would report it was charging in the OS but the charger module itself reported otherwise (the red Verizon ring didn't illuminate unless the charger was positioned a certain way in the device thus this was the only way I could supply it a charge and not hope it wasn't dead in the morning). When my Nexus 7 is drained, it draws enough voltage to get the charger to illuminate so maybe try one of these to really make sure it's still responding.
For the meanwhile, if you do decide to buy one, what was the last thing you/your wife had done? Was there root access?

Interesting about the charger -- don't think I have one that does that. Maybe I'll see if my VZW store has one, not sure yet.
She had just used her tablet as normal, and plugged it in like she does every other day or so -- the next morning grabbed it and went to work only to find out that it was dead. IE: not turning on.
- No root access (totally stock)
- I've tried holding the power button for up to 2 mins. - nothing
- Even tried holding the down volume and power for up to 2 mins. together - nothing
- Removed the back and unplugged the battery (plug was really tight) and left it undone for 5 mins and reconnected - nothing
- When plugging in to a USB on the computer, the computer dings like I connected something but - nothing
Perhaps I'll take it apart again and see if I can get a voltage reading on the battery with my multimeter... didn't do that before, but would be good to know if it is charged and not turning on or what.

Remove the back cover, locate the plug to the battery, disconnect plug by sliding from right to left, then replug. Should be fine after that.

Thanks but I already did that. Nothing changed. If I don't get it going soon I'll be forced to buy something else as she is getting impatient.
I have the same issue.
I bought a refurbish one and it was working great for 2 days and yesterday when I tried to open it, it won't turn on anymore and I was able to browse on it 5 min before.
I tried everything but I cannot find any solution...
When I plug into a wall I cannot see the charging icon and when I plug it into my computer it will do the noise that a device is plug but nothing happen... I wonder if its the battery that is crap

I own 3 of these N7 tablets and this has been the number one issue. Sent one for repair when it was under warranty. The supplied Nexus wall charger burn out quick, and aftermarket cables last only 3 months. I've had better results using the Samsung wall charger and cable.
OP, it sounds like your wife's N7 is in APX mode. Connect it to your PC via a USB cable, and open Control Panel's devices and printers panel. If it sees an APX device, and you didn't make NVFlash blobs, your only recourse is a motherboard replacement.

I just got my new N7 32gb GSM 2012 in the mail today. Won't turn on at all. I'm not going to bother. Going to return it. Quite disappointed, as I didnt realized this issue (apparently with the battery) was so common. Was looking forward to flashing cyanogenmod. Poop. Might just get a samsung tab now, which I think is quite overpriced for its specs.

If you're seriously looking for something other than an N7 then I'd suggest you look at the LG G-Pad.
I bought one for my Dad at Christmas and was amazed by how good the screen is, and the tablet generally, for the price. The LG skin is minimal and can be changed obviously with another launcher, and the battery life is better than my N7.

Hello. I created this account so I can finally ask some of my questions regarding this phone. I've had it since the January 6th shipping, and it's really been fine for the most part. I've the 8 gig version.
Anyway - within the last few weeks my phone has been refusing to charge on random occasions (it's really very random as to when it will charge and when it won't) - both plugged into the wall outlet via the USB power converter that came with my phone and plugged into my computer.
It's been pretty annoying, but nothing I couldn't work around. It would charge eventually.
However, last night I plugged it in to the outlet and it made the noise confirming it was plugged and started charging. This morning, I unplug it and it's non-responsive. It doesn't respond to anything. I have tried:
-turning it on with the power button; holding it down for an extended period and releasing
-taking out the battery
-plugging it in to my computer (which didn't recognize anything being plugged in)
-plugging it in to a different outlet with a different cable (phone came with two)
I've let it sit plugged in for three hours now and retried all of these things and still nothing... it's dead!
I'm not sure where to go from here? I guess I should have my husband call Dell.
Has anyone had any trouble with the sporadic charging?
Are there any solutions I've missed to get my phone to turn on?
You say you've let it sit for a while, was that plugged into a power source? Try that, it sounds like your battery has gone completely flat and probably needs to sit on a power source. Failing that definitely call Dell and get a replacement battery and charger and see if that fixes it, sounds like one of those items is your problem.

Yes, it has been (and still is) plugged in that whole time. I edited my post
Yeah, something is wonky, I just cannot pinpoint it. My husband's will sometimes not charge, too. But, much less often than mine does.
charging issues
In the last 2 days my VP freezes while charging overnight. Restarts when I take out and replace battery. It will also freeze when I try to use any app while charging. I tried to use Dell chat to resolve issue but got bounced around. I even had an agent tell me my service tag wasnt valid. I'll try to call 800# when I have a free hour or so (I'm sure the call will take that long). The first two levels of support at Dell seem to have no clue regarding the VP it's very frustrating. P.S. what happens with all the apps I've purchased if they need to replace my phone?

Have you swapped batteries with your other DVP? Maybe replacement is the only option, hit up @dellcares on twitter, they have helped me in the past and bypass the whole waiting on hold nonsense with dell mobility.
@tbvnz: all your purchased appls will be reinstalled automatically if you installed them via the Zune software on your pc. The ones installed via the phone can be reinstalled from the MP on the phone, just hit the Buy button again and it will tell you its already been purchased and allow you to download it again.
Update:
I snagged my husband's battery and put it in my phone. My phone immediately came on and is now functioning. My computer recognizes it as being plugged in and it's charging.
And, my battery in my husband's phone works fine. It is fully charged and his phone is having no issues.
Certainly this is annoying (and did in fact happen to my husband a few weeks ago where his phone wouldn't respond until MY battery was put in his phone, but we chocked that up to the battery being dead {which it was}.) but at least my husband and I both have DVPs and can interchange batteries... I wonder what someone who didn't have that option would do.
Certainly confusing that removing and replacing my existing battery wouldn't turn the phone on, but my husband's would - even though both batteries are at full charge.
Thanks for the help! I'm not sure if I should contact Dell about it or not. Clearly it's subpar performance, but I've not been completely impressed by this phone in the nearly two months that we've had them, anyway.
Good to hear you are up and running. You could keep an eye on the situation and contact Dell for a replacement battery if it occurs again.
Thanks. Yep, I'll contact them the next time it happens. Anyone else had this problem??

My brother and I have experienced the same behavior on both of our phones. Most recent was his this past week, exactly as you described. It would not turn on via the power button, so I swapped his battery with mine and his booted right up. When I tried his battery in my phone it showed a full charge. That has happened to me one or two times, randomly.

I've seen that behavior in my DVP (picked it up two weekends ago) and I can tell you how to work around it.
What seems to be happening is some kind of bug when you have it connected and charging and try to turn on/off the phone. If you notice, when it seems unresponsive, the hardware keyboard will probably still light up. This is because it's actually on but the screen just doesn't get any output/input.
What I did was this:
1. Disconnect your phone from the charger.
2. Slide the hardware keyboard down so you can see whether it is lit up (on) or not.
3. Hold down the power button until the exact moment you see the keyboard go dark (off). You have to be quick because it will try to turn right back on a few milliseconds later if you still have the power button depressed, leaving it still non-responsive.
4. Wait a few seconds, and press the power button as normal to turn it on. This time you should see the Dell logo, etc. and everything will be fine.
I've gotten into the habit of either leaving it on or turning it off before I connect it to my charger (it's my alarm clock so it's on almost all the time).
Hope that helps.
my DVP won't turn on either...
Hi - i'm glad i found this post because i've had my DVP for 3 days now and its frozen about 5 times and this morning wouldn't turn on or seem to take a charge. it was fully charged when i put it down last night and this morning there was nothing.
i've stuck it into a wall outlet for now and i guess i'll just wait for it. don't know what else to do. don't know anyone else around with the same phone, so that battery swap isn't an option. pretty funny that you realized to do that and that it worked.
anyway, i feel better now that i've complained about it. thanks.
Did you try pulling the battery and then booting it up? If that doesn't work, after a pull just leave the battery in the phone and let it charge. After 20 minutes you should see it power on.
So it's continued to happen with my phone whenever I have it plugged in to the wall with the brick that came with the phone. Annoying! Basically I cannot have it plugged in next to my bed; it can only charge on my computer. So much for using it as an alarm!
I will try the power down and reboot with the keyboard out. I know what you speak of with the flashing keyboard. I hadn't tried to see if mine is flashing while the phone is 'dead'.
Hey got my transformer today but no joy, It wont even power on . I charged it via wall socket for an hour, still wont power on so I tried charging it through usb on my desktop and still no dice. I tried the button combinations listed here http://forum.xda-developers.com/showthread.php?t=1032374 and was able to get a reproducible click noise but no screen movement what so ever. I unplugged it once in the beginning and it made a low battery noise but have not been able to make that happen again. Any ideas?
Thanks

Tried it. Windows does not recognize the device. Then clicking on properties it states that the device is not working. I'm guessing faulty cable. Will look for a replacement tonight.
As per the instructions charge it for 8 hours with the OEM charger and cable. Charging via the USB is pretty worthless. The charger is rated at 1.2 Amps at 15 volts. A USB port is .5 Amps at 5 volts, way less.
You need to install the Windows drivers to have ir recognized.
Sounds like a dead screen.
Does the power adapter feels hot/warm when you do your charging? Did you push in the power adapter until you hear a click sound?
@greeny2010 Yes and yes,
I will let it charge all night tonight and let you all know in the morning.
Ok I let it charge overnight and attempted to power it on. First I pressed the power button for ~10 seconds then waited ~5 seconds and pressed power again. This time the speakers made a pop noise and I heard the camera click but still no screen D:
Any other ideas? I really don't want to rma I have my final essay due Thursday and I stupidly sold my laptop to get this thinking it would get here and just work.
I read in another post where someone had a similar issue which was due to a bent pin where the transformer connects. I would inspect that carefully.

Just want to say I have done a lot of reading and testing before posting here. Disconnecting/reconnecting the battery, all possible button combinations, charging the battery externally (for good measure, it wasn't dead, tested with a multimeter).
This is my daughters phone, it simply shut off and refuses to turn on. However plugging it in makes it blink red. When plugged into the computer into a usb2 port it blinks red 7 times. When plugged into the wall it will blink red 11 times. The only plausable explanation of this I have found is this post http://forums.androidcentral.com/go...ed-light-follows-motherboard.html#post3719526 and this image which is the supposed fix https://i.imgur.com/WewiGBe.png .
Any more ideas before I call this thing officially dead? Btw well past it's warranty, so I can be pretty invasive in fixing it since it's really just a brick right now.

If you have to junk it, Expansys has a deal where you can get a remanufactured N4 8G is 129.99/ 16G is 149.99 http://www.expansys-usa.com/google-...9aU-aXzeibXDvErq.KMVvZ4neA&ito=LKSTM20TXf59aU or you can get both a 16G AND a Gen 1 N7 for 179.99 http://www.expansys-usa.com/google-...rtphone-bundle-16gb-tablet-16gb-phone-269434/
I took the N4 offer the other week, and all is well.
You could try a new battery. It could be that the cable is damaged, or something in the circuitry is damaged.

did the battery swap work? My GF's n4 has the same issue.
Battery tests at 3.72 volts, no button combos work, if I hold power and plug in usb get a solid red followed by similar blinking pattern.
She will flip if it is dead (luckily pics are auto backed up of the baby)
If a battery swap works, I will be all over a new battery.
On YouTube there is a video of the guy who had the same issue... He came up with a good solution.. Search "nexus 4 red light of death"

thanks for the response, I have tried pulling the battery, button combos, holding the power button for up to 20 minutes, vol down plus power, vol up plus power, vol up and down plus power.
Swapping cables, usb ports, wall chargers everything that every site / forum has suggested.
The only thing I haven't done is swap the battery, and since I have the same led blink combo as OP, if a battery swapped fixed him, it is worth spending the money, otherwise I am wasting $30 bucks.
Other posts have suggested the blink combo (7 usb / 10 power) might be a pmic chip going bad so I don't want to waste money on a battery if it didn't work for OP.

thanks for the update, yeah I bit the bullet and got my GF a moto G 2014. Not quite as nice as the nexus 4, but I got a good price on it.
So yesterday my phone worked great. I work outside for the most part. It rained its ass off. Phone did not get wet that im aware of. no water drops or anything on it. Had it inside my waterproof jacket. This was early morning..10am or so. I get home from work around 7pm. Phone still works. battery is getting very low though. At 8pm phone reboots..which it randomly does sometimes. I set it down, come back to it awhile later and realize it never came back on. Figured the battery was completely drained past 5%. plugged it into stock charger (not stock cable though but a highend cable still). Phone wouldnt boot up or power on or even show any signs of life. Tried other cables, charges, USB ports on computer, even car charger. Nothing. Set it on charge over night. Still not even a LED blink. Set it on car charger all day while at work. Not even a blink. I took it apart (taken many phones apart in my time haha) disconnected battery and plugged it in...nothing. tried power/volume down, power/volume up, all 3 buttons. held all button combos for over a minute. Still nothing at all. I have a new battery on order that I can slap in there and see if the battery is just completely shot but does anyone else have any ideas on what i can do to get it up and running again? Already had to buy a new phone G3! because i HAVe to have one for work. So i want to get this one working again so i have a backup in case this ever happens again.
Thanks for any and all help

tried to enter download mode, recovery mode, every mode i know of. with no luck.
and forgot to mention. when plugged into computer the computer does not notice anything has been plugged in at all. no sound at all. nothing under device manager
well i got the new battery in. didnt work. still no power at all. anyone else know of something i can try? i know the screen isnt dead because it would still give out sound when turned on or vibrate. but that doesnt happen either. is there some other thing i could test? how would i test the motherboard? power button?
This sounds like exactly what happened to my phone about two weeks ago. Phone was randomly rebooting one morning in strange intervals. Once or twice an hour at first, then more often as the day progressed. By the end of the day the phone wouldn't even turn on anymore. I had thought it was the battery as well but after bringing in to an electronics repair shop, it was diagnosed as a bad motherboard and the guy quoted me $130 to replace it. Considering you can buy the D800 off contract brand new for about $220 off the internet, I declined. I'm still really upset about it. I had already had it replaced by AT&T while it was under warranty. However, now my warranty has expired. I really liked the phone overall but now I'm not so sure I trust LG's hardware.
I'm using my brother's old iphone 4 now and it drives me flippin' crazy. I want to get a new phone as soon as possible but I don't know what to get. I'm so torn on the whole issue. Was thinking about the S6 but I've had bad luck with samsung in the past as well. I'd get a newer iphone but ios is so lame compared to Android. I hope you find a better solution than I did. :crying:

Hi guys,
My Nexus 7 (2012) turned off(not properly) when the battery level was low and won't power on. I tried a battery from a working tablet and tested my battery in another tablet. It seems like the issue is somewhere else.
These are the things I tried:
- leave it for a couple of hours charging (no battery sign at all)
- hold the power button with/without the volume levels while it being both connected and disconnected.
- tested my battery in another tabled and put a fully charged battery from another tablet
- made sure that the battery is connected
There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!
Both you and i, same model, essentially, the same circumstances. I also tried every method you mentioned as well. Even down to the flashing of a rom. Same results. I even tried "jump starting" the battery. Not wanting to give up on it. It sits in my closet like that boy in A.I at the bottom of the ocean, waiting... I know that is not the reply or help you were looking for. Just so you know, you are not alone..

Well, that's a good start, at least I am not the only one!
Have you tried to connect your device via USB? My laptop can see a connected device but it can't recognize it and I hear some sounds coming from the tablet when I try to hold the `power` button. This made me think that it can be a display/screen related, so the device works but we can't see it due to the broken screen/display. Don't know how to check that though.
Same here, stock Nexus 7, won't turn on, just switched off one day and won't come back on, have tried everything as suggested above, can't get it to flicker, doesn't even register the power connection with a green light or anything

I'm currently having the same issue, haven't used it in 6 months and when I tried to turn it on, nothing happens

I fix mine,
let it sit on the charger for a hour, then hold down the button for 20 sec
same issue here as well ive had it for about a year and im not able to access anything via my pc google help forums had no answer either, looks like we may be screwed..........
Hi, I just had same issue with my tablet only thing is that I was using it with ~20% of battery, nothing special - browsing the web using chrome, then the screen lit gray and shut off. After that no response either from charger, holding power button for 60+ seconds didn't work either, tried re-connecting the battery, still with no signs.
And then, I tried to plug in the charger and then pressing VolumeDown+Power immediately after connecting the charger. Suddenly got some response, that battery charging icon appeared, and it shows my battery charging, but from 0%. Still waiting to charge a bit until I can try to boot it.
I'll update this post with any news.
EDIT: When I connected my tablet to the charger it had that hissing sound, but after few minutes it stopped.
After 15 minutes of charging I managed to boot my Nexus7 with 7% of charge in it a that moment, It seems to work for now.
Summarry of what I did to solve my problem:
1. Opened the back of the N7 (I used a guitar pick for this) and re-connect the battery.
2. Then plugged in the charger and at the same time pressed VolumeDown+Power, battery icon lit up but went out, repeated step 1, and then step 2 again gave me animated battery charging animation which showed up for like 10 seconds
3. Waited for 10-15 minutes and tried to boot normally. And it works now

Hi guys,
My Nexus 7 (2012) turned off(not properly) when the battery level was low and won't power on. I tried a battery from a working tablet and tested my battery in another tablet. It seems like the issue is somewhere else.
These are the things I tried:
- leave it for a couple of hours charging (no battery sign at all)
- hold the power button with/without the volume levels while it being both connected and disconnected.
- tested my battery in another tabled and put a fully charged battery from another tablet
- made sure that the battery is connected
There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!

Honestly, I do not think it is the battery, I can see the Charge signal, and the Battery is showing 1,784 VDC tested unplugged and disconnected, my smart young co-worker seems to think POST is failing, I still never see a "Charging" indication.
Does anyone know , Is there a fail safe, say the battery is disconnected, and usb charger is plugged in, will i just see all 5VDC at the sub port, ?
I never see a screen flicker, DEAD battery sign, nothing.
co-worker, tried some things that made sense when he explained what he did, I would have to agree with him.
Now it is rooted, 4.x something I forget, Never went to 5.x did once early and did not like it, Back stock, ran 2 days no issues, Rooted again, 4.x still do not remember, worked great 3-4 months, Sons ran it to DEaD and that was it, put it up for 90 days or so, wife got new tablet, kids have Fire each, and here i am tabletless, CRAP, did not want to throw to much $$$$ at this thing, nor did I want to buy a new one.
Samsung Tablet here we come.
any body want this Nexus 7, it is a 2012 model.
