Help! My xperia xz2 compact won't power on, no response to charging - Sony Xperia XZ2 Compact Questions & Answers

HI everyone,
This morning I woke up to my phone not responding to power button. Screen stayed blank. The LED was blinking white, very fast. I tried a combination of hold power button, then power button + volume up, but nothing. At some point of trying these buttons the LED went off.
Now the phone is not responding to charging cable on power, charging cable in PC USB, and power button/volume up combination. I even took the SD card slot out to try. Been on the charger for at least 30 mins now.
The last time I did was playing a mobile game on auto-mode (which I often do and leave it to run until it runs out of stamina), but it shouldn't have drained the battery befote it finished. I go to sleep when it's doing that so no idea what happened on screen before it went dead.
Um, before I start to panic, can anyone tell me what's happened?? Help please?

[Q] [SOLVED!] Epic 4g Won't Power on. Will Charge though.

<Quote>My epic 4g won't power on. If I plug in a usb cable/ac adapter it will charge the device. The screen comes on and shows the green battery and the amber LED turns on and then turns blue when it reaches 100% charge.
But the power button does nothing. It won't power it on. Is there anything else I can do to force it to turn on?</Quote>
So I got it to boot up. You can do this by holding the power button down while continuously unplugging and replugging in a power adapter (or usb cable). You may spend 2 or 3 minutes unplugging and replugging it in (you need to do this rapidly) but eventually you'll be greeted with the samsung boot screen. If it makes it to the battery display screen you're not unplugging and replugging in quickly enough.
Hopefully o that anyone else who encounters this problem can potentially use their phone in a pinch or recover data off one with a broken power button. My power button is definitely busted and I'll need to get it repaired by sprint unfortunately.
Thanks!

Click to expand...
Click to collapse
Did you try putting it into download mode? may need to ODIN back to stock.
Ok im new to this forum, as i just ditched my evo shift and picked up and epic, but you might try booting to another menu. Try unplugging it and holding the 1 key on the keyboard then press the power key. If that does nothing then id have to guess ur actual power button is broken. You could also try pulling the battery witih it unplugged for like 5 minutes then put it back in and hold the power button for like 20 seconds and letting it go.
Edit: He beat me to it
It appears the actual power button is broken, neither of those solutions worked. Is there any other way to force it to power up without use of the power button?

Thank you soo much! I have a messed up Epic that has to be sent back to Sprint but I had to get my work information off of it or I'd be in it deep. Your trick worked perfectly!!

HOX not charging and turning on

Phone was like about 1%, I just wanted to see what time is it and connect it to the charger, but it discharged.
After connecting it to the charger, everything was ok, HOX started, but I wanted to check something, and it turned off.
I turned it on again, but it crashed after entering PIN, and I had to turn it off by pressing longer power button.
And from that time it doesn't charge nor run. Back of the phone is cold, the LED don't lit.
I tried many combinations of pressing power button and volume and with plug-in USB.
And I've "charged" it for about 1h and HOX didn't turn on.
Help me guys

Htc 10 charging problem

Hi every one,
last night, when my phone was fully charged and the green notification was on, I unplugged it, but suddenly I saw that my phone didn't run. Therefore, I pressed and hold the power button, but unfortunately, my phone didn't turn on. I plugged it again to the charger and saw that an orange light was blinking, and the phone was showing an empty charge icon. I pressed the power button again while it was on charge, and it tried to turn on but after few seconds it turned off. I was really nervous and distressful as it was for the first time to me.
I let it to be charged for minutes, and, then, I tried to turn it on again. This time nothing happened. I also tried the volume +/- and power button to reboot it but they didn't work.
Now, when I unplugged and plugged it again, I can't see even that orange light.
Please, help me.

One Plus-3 Black Screen. No LED No Vibration. Hardbricked?

So I had kept my oneplus3 on charge at around 10:00 Pm yesterday and fell asleep. Woke up around 12:00pm to see it was fully charged so I unplugged the charger kept the phone beside me and went to sleep. Today when I woke up I saw that the phone has a black screen and is completely dead. The LED light is not on. Plugged into the charger no response. Tried holding power button ..nothing. No vibrations or home button lights
Currently, there is nothing going on with the phone. No flashes on screen no LED. Absolutely nothing. Tried connecting to laptop (windows 10) dont see anything. It was working perfectly fine last night and i had used it for nothing but music then.
Question is.. is the phone hard bricked or completley bricked? what might be the reason? I searched youtube only to find 1 person with similar problem who had said that he kept the phone for 48 hours and when it was completely discharged he pluged in charger again and it started working.
I am confused. Have a lot of work documents inside and what if it stays the same after 48 hours?
Appreciate any help on the matter
update: Tried plugging in the charger a few min ago. The led turns red and Vibrates. Nothing else
Update 2: so after 24 hours of setting the phone aside. i plugged the charger and it went into charging. But now am facing a new problem. My bootloader is unlocked and the power button is busted hence whenever I press volume down and plug-in the charger it takes me to bootloader warning screen from where either it goes into charge or i press volume key and it goes into option which I again cant select cause power button is busted. Tried holding down the power button and connect to laptop(windows 10) no device detected and it works like normal charging. Tried to charge for a few minutes unpluged charger and start again .. it was stuck on oneplus screen. Any ideas??
