[Q] Is my Nexus 7 dead? Please give me options to charge/turn on

Good evening everyone, I have a Nexus 7 8gb, but the thing is, I cannot turn it on now.
It happened as follows:
I was using it every now and then, mostly to read and play.
I was using the charger to charge my cellphone too (XTC Explorer) as it was a lot faster, being 2amp/h.
I updated the cell to 4.1 and at the same week noted the battery wasn't running that long, but blamed it to the rom.
The cellphone also took a lot longer to charge with the nexus charger, yet again I blamed the rom.
I noticed the Nex was at 8% while reading so decided to charge it, but I guess I forgotten.
The next time I wanted to use it it wouldn't turn on. I figure it had no battery.
I plugged the nexus charger to the nexus a whole night and in the morning it still wouldn't turn on.
I figured something must be wrong with the charger, so I tried with the cellphone and nook color charger, but both are .5 amps/hour.
It wouldn't charge, neither connected to the pc (also .5a/h via usb) so I tried a psp go charger, as it is rated at 1.5 amp/hour, much closer.
I connected it at night and saw the charging icon (white on black battery with the ray) and left it overnight.
The next morning it wouldn't turn on either.
I've bought it almost two months ago and I really enjoy it =) but now I'm desperate.
I cannot call google play for the warrant because I'm in Argentina, and I don't believe they will ship me a replacement, nor anything. This one my brother bought from them, but he went back to US a few days ago, and I didn't think of giving it to him to RMA.
I tried keeping the on button, for 5 secs, 30 sec, 90 secs, 120 secs, and no dice. Also tried holding the Up Volume key to restart it, but no chance.
Please help!

Had a similar issue to this over the weekend after not charging for 2 days and the battery going dead. I let it sit on the original charger overnight and for some reason it did not charge. It kept booting and shutting down once it booted due to a low battery warning. It eventually got to the point where the screen would go to fuzzy lines and light but no boot.
To finally get it working I did a combination of a few things but don't actually know what got it going.
Put it on a different (kindle) charger and let it sit for an hour or 2, did several hard resets holding both just the power and also the up/down volume and power all at the same time for up to 60 plus seconds. I switched back to the stock charger and did an additional hard boot by holding just the power for 30+ seconds and it started booting and charging.
I did however put it on the charge again last night and noticed this morning it was still at half battery and didn't get a charge. I ended up putting it on a mifi charger this morning and it's charging again so don't know what is up with the stock charger. Also, have all the latest updates to 4.2 as far as I know as there have been charging issues reported with earlier versions...

Try this, it just saved my device:

try holding down the volume DOWN and the power key for 10 seconds, then release the power key and keep the volume down key pressed, and it will force the unit to restart into the bootloader from any stage, its effectively like pushing the restart button on the front of a computer and constantly pressing the delete key to get into the bios.

can u pm me what u used to get it working thanks

Unplug your tablet, then hold in Power + Vol Down + Menu. After 10 or so second the Touchpad should turn on and show the AC plug. Plug it into the AC charger and let it charge. If the Touchpad was completely dead and didn't have any charge whatsoever (you say that you've been charging for 3 days), you would want to charge it for a few hours first. It charges extremely slow in a powered-off state and likely won't get much more power than is required to boot into the low battery mode even after 3 days of charging while off.

[Q] HTC One M7, won't power up, charge, no LED, screen nothing

I was with Telus, and entered unlock code for carrier unlock few months ago, and 3 days ago. My HTC battery drained, it will no longer able to turn on, when I plug original cable and charger, no LED, and screen also blank as did not turn on at all. I did research on google, noticed lot of people had similar problem. I follow procedures at XDA below,
1. plug original sync cable and charger to phone for 10-20 minutes (I plug it over a day)
2. press and hold at the same time 3 buttons at the same time POWER, Vol +, Vol - for 2 minutes, i also tried 5 minutes as well.
3. after that release all buttons at the same time.
no luck, nothing happen.
I also tried plug sync cable to computer, I hear USB cable plug-in sound on computer, charged also 30 minutes, and did step 2 & 3 again.
same result, nothing happen as well.
Is there anyone can help me for this? Because I just went on vacation and got back, I was not able to backup all photos during vacation, so I do not want to lost all data and photos in phone.

Try holding the power button and volume down buttons down, while holding the proximity sensor directly under a very bright light (sensor is top left on phone)

I did the same thing, it won't fix.:crying:

HP Touchpad doesn't start or charge.

Hi,
My HP Touchpad will not turn on. This never happened before. Few times there were some small problems to restart, but I usually do the reboot by holding down the power and the home button and everything was ok, but this time it didn't work. I held it down for 15 and more seconds. I tried to push just power button for quite a while, too. However, it still does not wake up. Usual I keep my Touchpad in sleeping mode, and I didn't let my battery to drain but this time. I switch it off, and I didn't use it during 3 or four days and when I tried to charge it, didn't even recognize that it was being plugged in. The screen is still blank.
I tried to find any solution on the Internet, but everything was not useful.
You guys my last chance!!!
Are there any other ways to fix this?
All help appreciated. Thanks!!!
P.S.
My OS is Android Lollipop 5.1
USB cable is OK is charging my friend HP Touchpad without any problems.
I reset the adapter it means I turn this one way and later back.
I tried my friend charger from his HP Touchpad - nothing.
I left my Pad for few hours plugged - nothing.

One of mine died, I left on charger for I can't remember how long, maybe a week, picked it up and it was on. One other thing to try is pushing the home button 17 times. Good luck.

Thanks, it didn't help, but I'm still waiting for solution. I think that my Touchpad is not broken because before few times something similar happened, and I heard that sometimes when battery is really empty some people had the same problem.

Yup.. I hv tried all the above...and also tried connecting to laptop thru USB cable.. but absolutely nothing happening.. it's dead as a Brick

What did you do before

Nothing actually.. went to bed in the night and kept the phone aside.. morning it was off thought battery empty and kept for charging. But even after an hour I noticed it wasnt charging and I cudnt turn it on either..

maybe open back cover and see What happened?
replace battery or What?

or replace Screen?
have you done any system updates or opened auto update?

There was an ott update that day which got auto updated..

Mostly is that OTA hard bricked your device. Your device ran out of battery while installing it.

The mobile had enough battery and the update got fully installed over wifi. After that I hv used the phone too. In the night I went to sleep keeping the phone aside and morning this happened.

Maybe Another OTA came and bricked your device.
My Y9 Prime had recieved 2 updates in a row so I can confirm it is possible.

if that is the case I cannot help you but if it is battery bug（like Note 8 battery drained overnight and battery failed）you can try reconnect the battery or replace it but I am a noob of doing that

Do you have spare phones?

What happens when plugged to computer?

Ohh. 2 OTA updates....
No sound or anything Wen plugged to comp. It's still dead.. tried all combination.

then mostly 2ota bug or battery bug
if screen bug you will hear vibration

Ohh ok.. any solution for this...???
