My device Nexus 7 (2012) won't power up from the "OFF" state.
If I turn the device off, it won't turn on again, unless I connect power to it. Once the screen lights with the charge indicator, the device will turn on.
Battery state can be fully charged or almost empty or any where in between.
The power button does nothing, until the screen displays the charge icon, then it works as normal.
When the device is off it is only using the 'bios' level of system.
Running M-Kernel mr2 , was running stock kernel. Happens on both.
Any ideas or suggestions.

Can you charge this device while it is completely off? Any time I plug in the charger while it is off it turns back on and boots to CM7. If I then power off it will turn itself back on, is this normal?
Thanks.
Yeah, this is normal. Not sure why, but the device needs to be on to charge. Probably has something to do with software control or tracking of the battery charge. I'm sure someone smarter than me knows the real answer, but if you plug the device into either the charger or computer while off it will power on.
To charge it with it powered off....
Plug it in with it on....
Long press power...
Select "Power off"
This is the only way to get it to shut down and remain turned off while charging
Thanks for the reply but even when I select power off it eventually rebooted.

If you leave the battery in a very low percentage for weeks it will be dead. Then? How can you bring the nook to "life" again?
My S3 has started a strange charging problem and I hope someone here can help. My S3 has been charging fine and showing the LED, but since I plugged the phone into my laptop USB, now the phone stops charging if the screen is on. It doesn't matter if it is connected to a wall outlet or USB.....turn on the screen and the LED goes out and the unit stops charging. Under "Battery" options in settings it shows as connected and charging, but it isn't actually charging any. Use the power button to turn off the screen and the LED lights back up and the unit starts charging for real. I've turned off the LED(unchecked it) then turned it back on....no difference. Rebooted etc.....nada.
Phone is bone stock AT&T and I'm new to Android. Hoping it is a simple setting that somehow got changed.
Led is supposed to turn off when charging and screen is on.

You misunderstood part of the post. Not only does the LED turn off, it stops charging with the screen on. Under Battery options it "says" the battery IS charging, but it really isn't. Battery level continues to drop. Turn off the screen and it starts actually charging again.
Well it may be because you are using more power than its putting into the phone. Or it may just be defective. Have you tried another Rom yet?

Are you using the USB cable that came with your S3? Is your laptop plugged in our running on battery when this happens? I also believe that you might be using more amps to run the screen and Wi-Fi and whatever else is running on the phone than the USB can output. What generation USB port is in your laptop?

If there is a thunderbolt on the battery icon, then that means it's charging. When you turn on the LED option when charging, it only turns red when the screen is off, and turns green when it's full.

Your laptop doesn't put out enough juice

So, my phone ran out for battery and died. Plugged it in over an hour ago, but the phone will not switch on. Anything I can do?

Are you running any custom kernels/Roms?

Nope!
Something similar happened a couple of days ago. Held the power button for around 10 seconds and a red notification light came on. I think it was flashing as well. About 10 or so minutes later the screen came on. This time the phone is just dead...
Have you tried any button combos like- power + volume up + volume down.
Also did the phone run out of battery normally or was there any battery drain?
This doesn't look good for n4.
Hold power and vol +/- to enter recovery mode and then restart.
But before make sure ur charger or outlet works.

None of the combos work. It's as if it's not charging...
Weird. Plugged it into my laptop to check if that worked. Nothing. Plugged it back to the mains and a red notification light started flashing. After about a minute the screen came on with the battery animation. I managed to switch the phone on now. The wallpaper was reset to the stock one, but everything else seems to be fine.
I got my Nexus 4 yesterday and I did battery recalibration.
Everything on, WiFi, BT, NFC, brightnes high, etc. and Stability Test.
After a while the phone switched off, because of 0% battery.
Then I plugged the phone into the charger. Phone was off. The screen showed a battery loading symbol with "0%" number.
After half an hour I went back to the phone (still off) and pressed the power button. Still 0%.
The charger wasnt warm too.
Then I switched the phone on and suddenly it was loading. Charger went warm too.
What happened here?
Is the phone not capable of loading when powered off?
Purity ROM 4.4.3 and AK 301 kernel
charger is original, cable from Nokia.
The phone should be capable of charging when powered off, what your describing sounds like a strange instance, but as long as its working now then I don't think anything bad happened.

Hi, I have a Google Nexus 4. For some reason, the phone will not turn on. It is fully turned off, but charges properly. When connected to charger, it displays the battery charging icon, but when you hold down the power button, nothing happens. The battery seems to be charging properly and the display seems to be fully functional as well. There is no root done on the phone or flashing. The phone has never been worked on before, does anybody have any suggestions as to what it could be? The power button clicks properly but I cannot turn on the phone at all, please help.
How much is the battery percentage? And is your notification light blinking red? And when was the last time you used the phone and what was the last thing you did?
The last time i used my phone was over 8 months ago, the battery indicator on screen shows around 80% which was definitely charging, it was dead to begin with and i left it charging for an hour nd a half before attempting to turn it on. There was no red light on the notification that is typically set when the phone is on and charging. The phone is completely turned off. And when charging doesn't show a light.
