Device Won't Turn On

Screen went black during phone call, audio still present. Then the phone shut off and refuses to turn on, no charging led when connected to power supply. Battery still had 75% charge during call

Have you tried holding the power button down for 10 seconds?

Thanks. This has also happened on my girlfriends device numerous times.

Similar thing happened to me, i was charging my One X while it was off (the battery completely depleted).
The notification LED was on (red) indicating it was charging, the LED turned off after about an hour of charging, i tried to turn it on and nothing, absolutely no reaction.
I've tried holding the power button for 10 seconds, also tried a vast combination of buttons;
Volume up + power.
All three buttons at once.
Any suggestions before i take it to the shop?
UPDATE:
5 minutes after posting this the LED light turned on, i tried to turn the device on and it did, so everything seems to be fine now, i just don't get how after an hour on the charger, when i turned it on just now my HTC One X battery was at 2%
In any case I won't be letting the battery deplete to 0% anymore

@dusan do you have CWM as recovery? It is known that battery-charge is broken, even when the device is off, when cwm is flashed.
Try to get into fastboot after some while, flash the stock recovery as fast as possible and turn the device off again for charging.

That would explain it, I do have CWM, I don't know how but I guess it charged just enough juice for me to turn the device on.
If I flash stock recovery will I be able to recharge the phone with the device off ?
Also would I lose root in that case?

Power button Problem??

Hey Guys,
I have a strange problem with my Gnex. The power button works fine when the device is on.
But if the device switches off for any reason (low battery or manual shut down), the Power button does not work any more. The usb charger and connectivity is fine when I connect while the device is on, but there is no response when device is off. Its as if the device is dead when it switches off.
It turns on by fluke sometimes and I dread it switching off again. Can anyone point me towards why this may be happening? I am on latest PA, with leankernel stock settings.
Cheers,
Abhishek

I have to "long press" the power button (about 2secs) for it to turn on, it won't turn on if I just press it normally. Could this be the case?
Have you tried checking the battery connections (is it sort of loose inside), replacing the battery?
This may escalate to something else: You need to be able to enter fastboot mode by pressing power+volume up+volume down, WHEN the device is OFF.

I guess Your battery is down. Did You try connecting it to charger? What do You see on phone when You try the combination of power+vol up?

Did you try holding down the power button + volume up key? Its to force reboot the phone. Keep the combination of keys pressed till your phone vibrates! Hope it helps...

Get flashtool and drivers plug phone into it and see if flashtool detects anything on it. If that don't detect it unplug.
Hold the up and down vol button and press power button and see if it vibrates or anything. If still nothing then get a t6 or t8 screw driver remove the back of it and remove the battery and get a ohmz meter on it and test the battery or connect to a battery tester. Sounds like battery dead on it.

Tablet won't turn on / charge

Hi,
I've only had my Samsung Galaxy Tab S for a few weeks. Whilst on a plane the battery went to 0%.. no problem I thought as I'd simply charge it when I got to a power source.
However, when plugged in, nothing happens. No LED light, nothing on the screen. I've plugged it into a wall socket and via USB into a PC. I have held down the power button, home and volume down for a period of time, as well as just the power button and volume down.
Has my tablet gone kaput?
Cheers,
Titanium

I'd just let it charge for a while. It'll take a bit before it comes back to life if it was completely drained.
If you still don't get any response hold POWER + VOL DOWN.

Should it show any lights? It's as if it's not even charging at all.

If it was powered off I'd expect the battery icon to show.

Yeah, tried to hold it down. No LED lights and nothing shows on the tablet. It's as if it's just dead.

There are no leds.
I know someone else had the same problem. They used a different charger and it worked.
Try that first.

I had this problem.
You'll have to pry off the back cover, remove the wire that connects the battery to the motherboard. (A battery pull, basically).
Keep it off for 30 seconds. Then plug back in.
Use ifixit for details about opening. Feel free to ask for more help.

Try this one.
1) connect the tab to PC
2) press Home, Vol Down and Power simultaneously up to a screen appears;
3) press Vol Down to cancel and reboot the tablet.
John.

Now there are a few things you can try...
First check your charging port for any dust or any foreign particle. There has to be a small gap between the base of the charging port, and the small slab above it. Carefully, using a board pin, try and push that slab a bit up, don't apply too much pressure, just enough to make it move slightly!
This can happen sometimes if you drop your phone.
Next, make sure your charger, and the USB cable are working fine.
Also tell me if you have any Xposed module for your battery installed on your phone!

Thanks so much for that.
This morning, I plugged my tablet in to AC charge before leaving for the day -- battery was at ~30% and all was well. This evening, I came home and the tab was stuck at a weird Samsung logo -- not the normal boot with colored ovals, but the logo surrounded by a moving star field, never seen before, and could not get the tab to respond, turn off, do anything. Tried many wacky suggestions found on the intertubes to stop/start it, including holding power plus touching the screen for > 30 seconds, none of which worked. Never would have thought your suggestion for download mode would work, but it did on the very first try.
I'd like to know how the tab got into that state, and what that star field logo is about. But at least it's working again, for now.
Thank you.

That's the normal lollipop boot screen.

Asus Zenfone 2 Unable to Start

My Asus Zenfone 2 ZE551ML 4GB is unable to start. Once i press and hold the power button, it vibrates continuously and afterwards i tried to off it by pressing on the power button, the orange flash comes out for like 1~2 seconds and the vibration stopped. I am unable to even soft boot my phone or even go into the fast boot. Any advice?

Do you see the charging animation when the phone is connected to a wall charger? Could the battery be completely drained?

your battery might be completely drained. remove it and charge it with external support.

Try to press power button while connected to charging. I faced once simillar issue. It is bcoz phone is powered on and hanged.
