So i was playing dead trigger with my sixaxis (awesome combo btw) with an overclocked kernel. everything was going fine till i saw the 14% battery left window and it went away all by itself very fast. i didnt think anything of it. (this whole time i was plugged in) anyways, i played for another 45 mins and all the sudden, i got some static and then a shutoff. i let it sit for a while (maybe it overheated?) turned it back on 10 mins later. went good for 5 mins, then shut off. the screen was just black. i un and repluged in the charger and didnt get the white battery symbol. i was thinking "oh **** i just fried this thing" so i took the usb cable out of the charger and dont ask me why, but i smelled it. and i instantly knew, burnt electronics. got my droid x charger and plugged it in. instantly got the battery symbol. this is a temp fix cuz its only 700ma but does anyone know where i can get another charger, possibly better quality, or a way to fix this? for some reason my computer just doesnt have enough oomph to charge it. its probably only ~500ma.
Thanks in advance.
P.S. Anyone else have this problem?
yea happened with my wire too. like the adapter piece still works its just the usb wire thats fried
Found this link on the charger issues thread

it's not a detachable usb charger, but should work.

It might be my cable, but thats the one im using with the droid x charger soo... yeah.
i forgot to mention that the charger smelled burnt too but i though maybe it just runs hot.
Thanks for the link to the charger!
One last question.
is this the same way as the (dare i say it here) iphone charger that couldent support the phone running and charging the battery? because my friend burnt up his charger by doing that. im thinking about making a 30amp usb port and just let the onboard battery charger take care of it. then again, id rather the charger blow up than the little processor for charging the battery.
And JESUS these captcha's are freaking unreadable!
All of the voltage looks the same as the Asus charger. The reviews also state that it works like the OEM charger.

Well even though the charger seems to be working again, I will probably buy that one because the plug doesn't come right out the back of it. Thanks

Does it also do the same deep cycle charge that the OEM charger supposedly does?
Hey everyone,
I've tried searching, but no luck, so here's my issue.
My nexus 7 was around 25% battery last night so I plugged it in for the night.
Woke up this morning and the backlight was on, but the screen was off.
When I unplugged my n7 the backlight turned off. Hitting the power button had no effect.
I then tried pushing and holding the power button for roughly a minute, nothing.
I have disconnected the battery and still no response from the unit.
I plugged it back in for roughly a minute as well, still nothing.
Unfortunately I don't have access to a charger right now.
Is it possible the battery is dead even though it was on the charger all night?

Weird.
Just plugged it in to my car charger and it booted up. Battery is completely dead, so I guess with the backlight staying on all night it didn't charge.
Now why would the backlight stay on if the screen is off...

Don't go flashing different roms and kernels now like most of the idiots here, it could just have been your charger being faulty or a bad connection to the tablet overnight. if the problem happens again then you can investigate further.
BTW, were you charging from your PC/Laptop with a USB cable or through a wall adapter? i've had issues in the past charging my Nexus 4 and 7 not charging overnight on my PC
I feel like a broken record but since I've fixed a ton of n7s with loose battery connections, I would recommend checking the internal battery lead to make sure its not loose. Asus didn't do a good job of making sure all n7 batteries were secure and this allowed the battery to shift and pull the power lead out. Some clear scotch tape on the connector and one on the battery (avoid the copper tape areas) will eliminate this problem if that's what you have.

I ran into this problem. Initially, my Nexus 7 didn't start. When I plug in the charger the screen would flicker from time to time but there's no indication of charging. So I decided to open it up to see that the battery cable has loosened. So I managed to fix it and use it happily thinking that it won't happen again.
Since last week, the same issue happened. I thought it was the same issue and opened it up to see that the battery cable is firmly in place. So I got a shock. I removed it and re-inserted it again to see if it fixed it. But nope, it won't turn on. And now it's been a week and I don't know what to do It's nothing wrong with the loose cable cuz now it's firmly in place.
Now when I plug it in to charge, the screen will just flicker (as in the back light will turn on and off in 5 sec intervals). What do you think I should do? I tried holding the power button for 30 secs as well.
I bought this new from eBay and still under warranty. But I live in Sri Lanka. So when I bought it, I had to ship to a friend in the US and had to wait till he came down. So it's not easy for me to ship back and to receive another device. Hopefully I can find a solution to fix this myself.

Make sure that the cables between the battery and the connector are intact and not broken. One or two people reported a broken cable.
Does it boot while plugged in to the charger with the battery disconnected ? You could simply have a bad battery.

I checked again. The cables aren't broken. They are all in good shape.
It doesn't boot when I plug in. Actually it doesn't show anything on the screen. If I look closely I can see static flicker on the screen from time to time. Just like the static in TV but much much less. Like only a few of those in certain places.
When this happened the first time I opened it up to see the loose cable. So fixing that helped it then. But now I dunno what's causing it.

Might have to try a different charger, maybe something stronger. I JUST had that problem with my GF Nexus 7. It wouldn't boot with her normal charger and the screen would flicker like a TV. I used my Nexus 4 charger and it worked.
She had left the battery fully drain for over two weeks and I think the battery didn't appreciate it.

So i was charging my phone with a wireless gear 5wc800 and suddenly there was a strange smell.
I head over to my phone and noticed the smell came from there.
I looked the charger and the thing was so damn hot i couldn't even touch it at the upper part.
Luckily my phone didn't get that hot and nothing has happened to it. :angel:
Also the plastic is melted away at the upper part of the charger.
All be warned.
Thanks for the warning. I got one of these chargers but since it barely charged my phone I haven't been using it. I'll just throw it out now. Thanks!

Thanks for the heads up and the pics.
Sorry to hear about the melting, although I do think it's funny how the melting is right by the QC Passed sticker.
Last time I used it I picked it up only to see that it had 2% battery left and before I could get to the charger it automatically shut off. I figured the battery just died so I put it on the charger, didn't see if the screen/battery indicator came on since I have a cover case on it, and just left it there for the rest of the day/overnight. The next day I took it off the charger but it wouldn't come on and still hasn't. I used the original ASUS charger that came with it, tested it on my N4 and it charges, but no indication of it working on the N7. It's been about a week and I've tried all the button holding combinations to try and wake it up. It's the 2012 Nexus 7. I need help.
Also, I've never messed with the bootloader, I am unrooted and running stock. I last updated to 4.3 OTA and I read some of the bogus things that happen after the update and didn't think it would happen to me but the tablet is literally bricked.

I did have this problem once, but it resolved by plugging it in for a few minutes, plugging out, waiting a few seconds and repeat until the screen shows the charging icon. After a few of these, it was working again.

I had a similar issue this weekend. To get it working, I left it on the charger for a few minutes and then while still on the charger I held in the power button and then the battery charging icon came up. I was also going to recommend checking the USB cable but you've already tested that. Still trying a different cable wouldn't hurt things either. Well I hope something in that rambling helps.

last week i got this issue twice. try this method, first plug your charger at least one hour, its okay if the screen just dark (better if you got something like little flicker or flash). then plug off your usb charger, then plug in again, right after you plug your cable press power button + volume down and wait.
maybe it will hit and miss, but this is the only method that i have tried and works.

Agreed with this one.
I had a situation where I was playing Magic 2014 plugged into the charger, but the game is so CPU intensive it drains the battery faster than I can charge it. I thought I had enough battery but at some point the tablet did an auto-shutdown right in the middle of a game, while still plugged in too. This also resulted in some crazy screen flickering and scary noises, which subsided when I unplugged the charger. When I plugged it back in, seemed to be dead as a doornail.
Anyway what worked for me was to unplug, plug in the charger and immediately hold down power+vol down after it went in. This brought me to the bootloader screen and I was able to get started.
Happened to mine a couple times since being on 4.3. Seems not to like getting completely drained. Anyway, after charging for a bit to make sure it had some juice I plugged it into my computer and held all three buttons. It booted into the bootloader. I selected reboot device or whatever it is. Then moved it back to the wall charger to let it get fully charged.

I have been using my nexus 7 2012 for a year now .. it worked brilliant .. but now this horrible issues has sprung in from nowhere .. the battery wont charge up, or rarely it does,, but very slowly. i am running stock 4.4 unrooted . i have checked my ports for dust, swapped several cables and chargers (also used the original charger and cable). but with no luck. Surprisingly the problem appeared suddenly, one day it charged normally , the next day i left it on charge at 60% and returned to find it on 59%.. help me .. this is driving me crazy
Install the Battery Monitor Widget - should give you an idea of charging/power consumption. I'm assuming you've tried using the stock charger and cable?

Yes i used stock and non stock chargers and cables .. i am using battery widget reborn app to monitor the battery stats.. i also attached the screen shots but for some reason they are not showing up
I think your battery connector is messed up. U might have to open your tablet and disconnect then reconnect the cables.

Search in the forum people have fixed it many times u have top open up your tablet and dc/rc yout battery.
]I too have this same issue....
I have the official dock and never had any charge issues until yesterday....
While it's in the dock, it clearly shows it charging and yet the battery meter appears to be losing charge...
I have tried with the original cable and plug among other cables and yet nothing...
The only way for me to get charged is to turn the unit off and yet it still charges painfully slow...
Anyone with a solution other than opening the thing up and hoping it's the plug?
I am running 4.4.2
Mine's having the same problem. It seems to be a hardware problem.. It's charging very slowly or can't be fully charged.
* I have other devices running 4.4 without charging problems.
Mine started with the 4.4.2 update....
It's very strange... If I turn it off and charge... it charges (again) very slowly.... 3 hours and I went from a 2% charge to 59%...
Doesn't matter if I use the dock or plug it in direct.....
So, to me... I would say a software problem... I just don't want to do a full reset and re-install if I don't have too...
my wife's was all the way dead today after not being used and wouldn't turn on. left it plugged in for 30 min and it powered on with only 2% battery. i t is stock unrooted and everything was all good until 4.4.2 is now charging very slowly. I switched to a non oem usb wire with the asus charger to see if it helps. it is the only stock android in my home (out of 7 devices) and I plan to keep it that way for now.
I've been having this issue for about a week and its not fixed. Anyone here can link me to the post where the guy DC/rc his cables? I'll try anything

N7 is very easy to open and close back.
I had the EXACT same issue 2-3 times this year and disconnecting the cable and reconnecting it back fixes it EVERY TIME.
The battery cable is short and the battery is loose so movement pulls the cable out. Not all pins are touching so it results in poor contacts or no contact at all.
Its a design flaw that can also be fixed by sticking a folded paper under the battery.
Voilà!

I'll try that when I get home. My n7 has not been charging for so long its starting to scare me. I tried pushing the cables in but it seems like its pushed as far in as it'll go.

Ok...
I have opened it up and reset the battery cables...
They originally looked pretty secure though... pretty tight....
Here's hoping that unplugging and plugging the battery back is solves the issue...
I be back....

Tried unplugging and replugging but it's still the same. I think it's my charging connector though. It randomly disconnects when I plug it into the PC. Tried with 3 different cables even the stock one. But I'm not sure if it's the port or the battery. It charges up to < 60 slowly but it doesn't go beyond that and starts draining. Thinking of selling it and getting a flo instead

Just a thought, but another possibility is that the ribbon cable to the USB/headphone jack flex assembly has worked loose to the point of intermittent connections. See "step 10" of iFixit's N7 teardown
Or, if the connector itself is mechanically damaged, maybe there is some way to buy just that Asus sub-assembly. Anyone have a source?

Edit - wow, folks are selling them on eBay for US $50. yikes.
I have the same problem, I purchased a nexus 7 charging dock from Amazon and it charges flawlessly. The dock charges using the 4 pins on the side of the tablet. BTW...The charging dock is under 24.00+ Shipping.
