Phone shows no signs of life - Xperia Z5 Compact Q&A, Help & Troubleshooting

I've had my phone for about a month with no issues. It was at about %85-90 battery when I put it in my pocket. About 10-15 minutes later I took it out of my pocket and the screen wasn't waking up. Holding the power button does nothing. Plugging it in to the wall does nothing. Plugging it in to OSX, Ubuntu, and Windows does nothing. Holding power and volume up does nothing. I have absolutely no idea what is going on.

So after a few hours I tried holding power and volume up again and felt a vibration. It could have been a phantom vibration, I don't really know. I then opened the compartment where the SIM card and SD card go and saw a small orange button. I took out my SIM card and held that for a while and felt three vibrations. I waited a few seconds and held the power button, and low and behold, the phone turned on.

Help! Galaxy Tab won't turn on!

I was watching a YouTube video, and my Tab just shut down. It did feel really hot on the back, now that I think about it.
But I've tried everything! Keeping it plugged into the wall, hold power for 30 seconds while touching screen, holding for 15 then for 7, Volume Up + Power, Volume Down + Power, and plugging it into the wall. Nothing's working.
I have a Metallic Grey 32GB with the latest TouchWiz Rom.
Please help.
i had the same - it seem to have restarted by having it plugged in the PC and then pressing Power + Volume up and volume down all at the same time ... strange though
I've had it for about 9 days and have used it every single day. Last night I downloaded 2 movies onto it and everything was fine. Today it would not power on one bit! I charged it over night so the battery shouldn't have drained. I ended up fixing my problem by doing the following:
Held the power button.
At the same time, placed a finger on the screen.
Held it down for 15 seconds or more and it booted up!
Not sure why it only worked when I put my finger on the screen.
I ended up exchanging it either way just in case.
i had a similar experience when it looked like the images on my screen was tarring and making really odd graphical errors, and then shut off... but i could see that the backlight was still on.. So i help power button untill backlight turned off.. and then plugged it into the charger and turned it on holding the power down button, which luckly got me into recovery.. i then reflashed the kernel, seems to have been a dodgy flash, but its working now..

[Q] Sudden, rapid discharge - will not power up

Hello All,
Been reading threads regarding similar issues since my issue occurred last night, but none of the fixes seem to do the trick for me. I am on AOCP CP2 basically since the time I got my Note, and haven't had any issues with battery, charging, or anything else for that matter. Last night my phone gave me a 15% battery warning, and by the time I checked it 5 minutes later, it was down to 1%. I went and plugged it in, and it had died by the time I got to the charger. Plugged it in and an empty battery symbol with the 'refresh' icon in the center appeared. Let it sit for about an hour then came back to power it up.
- A normal length press of the power button did nothing
- Holding the power button for about 10 seconds yielded three vibrations, then the display of the empty battery with refresh icon, which promptly disappeared
- Holding power + vol. up, power + vol down, all three, power + home + vol, all result in the same as above
-Computer does not recognize the phone via usb
-Removing the battery and connecting to computer via usb makes the phone vibrate repeatedly. Adding the battery while this is happening gives 3 vibrations and the dead battery with refresh icon on the screen
Tried:
-Leaving it plugged into charger overnight
-Removing battery/sim/sd card for various lengths of time
-Holding power button down with battery removed
-cleaned usb port with toothbrush (wasn't that dirty to begin with and hasn't seen water)
I don't have an extra battery or charger to test things out with at the moment, but if anyone has any insight beyond the things I've already tried and read, it would be greatly appreciated! Happy Thanksgiving!

This happened to me few times.
After charging it for a bit, I removed battery and put it back. Long hold power.
I just repeat this and eventually it will turn on.

SM-T560 charge/boot issue.

Hi,
I got hold of one of these tablets that appeared dead, left it charging overnight and it started without issue, the battery was at 67% at this point.
I then shut it down and held the Home + VolUp + Power to enter download mode as I wanted to install TWRP.
Nothing happened, but not only that, the tablet failed to boot again whatsoever. I took the back off and unplugged the battery, held the power button down for 30-40 seconds, reattached battery, still nothing, so I decided to leave it on charge for a bit more and try to figure it out later.
Later came along, and I picked up the tablet and for some reason pushed the home button 3 times and it displayed the battery icon, showing 100%, great!
It still won't boot though and I haven;t been able to reproduce whatever I did to get it to show the battery icon again.
I've tried every combination of holding down Home/VolUp/VolDown and Power that I can think of for different amounts of time and still nothing.
Had it plugged into the computer too and monitored dmesg for any signs of life and still nothing.
I'm thinking (but hoping not) that it might be a physical problem with the power button, but it feels fine when pressed.
Is there some magic trick that I don't know about that could help here?
Many thanks.,
g
EDIT: I have left it plugged in for a few hours and periodically the battery icon appears for a while (now at 99%), then disappears. Tried to switch it on with the power button while the icon is on the screen but no go, same with different button combos.

Nokia Lumia 920 just won't turn on

Hi guys, so I recently came across my old phone and just remembered all the things I had on it. However when I try to switch the phone on, nothing happens. I've left it on charge for a few hours and still nothing. I tried to turn it on again (even during the charging process) and still nothing. I then gave it the old soft/hard reset by holding down the power+volume down button for 15 secs, nothing. Then held down all the buttons....nothing, no vibration, no form of life whatsoever.
When I plug it into the PC, the sound of a device being connected plays, then the disconnect sound follows about 3 seconds after. I tried the soft reset method when I plugged it into the PC and after about 10 secs, the same sounds played as if my computer had detected a device but then disconnected it. This must mean there's some sort of life in the phone right? Any chance anyone knows a solution to this?
Charged it for about 4 days, still no sign of it turning on!
After charging, press and hold Vol-down and On/off buttons together for a longer time. It should vibrate and switch on.
Best regards,
Joachim
