My nexus 7 died after a couple days without use, obviously. As usual, I plugged it into my computer, where I got the message "USB Device not recognized." My nexus 7 won't charge hen plugged into the wall either. Could I have done this, or what can I do to fix it?

How long have you left it plugged into the wall charger?
Use the original cable, plug it into the wall. Let it sit for an hour or two then try to boot it up. If it does nothing, take the back cover off, unplug the battery, plug it back in, and try again.
Have you tried holding the power button for a long time?
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.

So my battery dies on my 8125 yesterday...no bigs, I plug my phone into my car charger. The orange light comes on, it has issues booting up, I power it off and keep it plugged in on the drive home from work. I get home, plug it into the wall charger and keep it there for a couple hours. It won't turn on. I figure, okay the battery is way drained, plug it back in and leave it there overnight. I wake up this morning and it still won't turn on. I take out and reseat the batter and SIM card...nothing. Plug it into the PC and it doesn't even recognize that I plugged in a device. I think its dead. Any ideas before I send it back to Cingular?
update:
i tried this: http://forum.xda-developers.com/viewtopic.php?t=40399 and at first it wouldnt power up after plugging it directly into the usb. five minutes later? success!!! woot! that thread needs to be stickied.
Okay not sure that this works but has been mentioned before.
While plugged in to power/USB hold down the power button and then wait.....then press the power button once.
might work
I´m on Paranoid Android, last version. I was whaching a movie with less than 4% battery, and It powered off. Problem is that It doesn´t boot and It doesn´t charge either.
Please please Help!!!
Sorry for my english
Hopefully your up by now after letting the device charge for a while. If not I'll throw this fix out in case it's a software problem. I have no idea, but: The Nexus 7 has a similar situation of not accepting charge after the battery runs dead. Maybe the same fix will work? With the charger plugged in, hold your power/vol button combo to boot into bootloader/recovery. From there select power off. Then the tablet "should" accept charge. It's the first idea I thought of, but I thought that was an Asus problem.

The problem is that you can´t boot into bootloader/recovery. Tablet doesn´t respond. When charger plugged in, It shows icon of battery when pressing power button but it dissappears in a second....
Hold power button 15-20 seconds until it vibrates & release. If no boot then, unplug and try it. I had this problem once also. Mine finally booted when unplugged for some reason (after being on a wall charger for a couple hours). Someone told me during my ordeal to first plug into a computer for the 1st hour, then go to the wall charger. I think holding until vibrate was the key for me, or so it seemed.

It seems to be charger´s fault. I can confirm it in one hour...
Edit: It was the charger...

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!

Hello everyone.
My Nexus 7 tablet battery drained and when I went to charge my tablet, nothing would come up.
I've tried holding the power button and volume down for 30 seconds and still no luck. My tablet backlight only turns on and then fades away after a few seconds. I've tried all other solutions with the buttons and timing it with my USB charger cable, plugged via wall charger and USB with computer.
Urgent help needed!
Thank you in advance.
Open your n7, unplug battery for a minute, then reconnect battery and charge it.
This may help, if not I am wrong.

Hold down volume up and down and the power button. When you get into the bootloader use the volume up/down key to select power down. Power it down and then plug in and let charge. Should work. It did for me.

Hi,
I have a nexus 7 2012 and it worked fine and runs CM 12. The other day I powered it off by pressing the power button then clicking the power off option in the power menu. When I turned it back on it didn't boot up and I ended up having to hold the power button for ages. Powered if off again the next day (only use it occasionally) and when I went to turn it back on it didn't boot again. This time though no matter how long I hold the button for or leave it on charge nothing happens.
I've tried everything from trying different charging cables, plugs, plugged it into laptop, pressing power + volume down and even pressing all 3 buttons. I've popped the back off and unplugged then plugged back in the battery. Nothing works there's no sign of life at all, no screen flickers no nothing I'm stumped. Think when I powered it off it was at 15% battery if that makes a difference?
Only conclusion I can come too is that the charging port is broke or the circuit. Sadly I don't have anything I can use to try and charge it using the four pin connector at the side to test it. Only thing I haven't tried is to "jump-start" the battery. Just take out battery and strip a usb cable and plug the power wires directly into the battery for half hour but not to sure whether to do that or not and wanna make sure I have exhausted all other options before trying that.
Any ideas?
