Phone died randomly and now won't power up/charge. Neither LED nor screen turning on.

My phone was running CM12.1 (a week old build). Obviously rooted and runs TWRP.
I texted someone and left my phone with the screen turned off for about an hour. When I tried turning on again, nothing happens. The battery was about 80% the last time I used it.
Things I've tried to get it to work:
1. Charging it with the wall charger. [Nothing happens. LED doesn't turn on, phone doesn't turn on]
2. Plugging it into my PC. [PC doesn't read it. LED/Screen unresponsive]
3. Tried vol down key + power to boot into the bootloader. [No response]
4. Tried vol down key + power, then plugged it into my PC without leaving the buttons and waited for a minute. [No response]
Can anyone explain what the hell went wrong with this? I just use my phone for calls/browsing/texting. Didn't overclock anything. It's been rooted since day 1 (2 years back), and I last installed the CM rom a week ago so it wasn't due to a bad flash.

[SOLVED] Stuck in boot loop: No image, short vibration every ~5s after battery drain

SOLVED: had display repalced.
Hey there!
I've had this Zenfone 3 Zoom ZE553KL for almost 2,5 years now and this is the first real issue I had with it.
One night I went to bed with ~30% battery remaining. When I woke up the phone was dead and holding the power button only made a short vibration. No image on screen.
Here's the things I tried:
Plugging it in: THe charging LED lights up and the phone vibrates quickly every 5 seconds or so
Leaving the battery to drain for 24h: The phone still starts vibrating when I press (or hold) the power button
Holding PWR and VOL+: The phone starts this vibrating cycle agian
Connecting to a PC via ADB: adb devices shows nothing. fastboot devices shows nothing. The phone had USB debugging enabled.
I did those things with and without the SIM card.
Any ideas how to troubleshoot from here?
Cheers!

Not much you can do. Try opening the phone and disconnect the battery for few minutes.

Disconnected for 5 min. After reconnecting, same behavior.
Will try leaving for 1h, although I doubt it would make any difference. After 5 min all caps should be discharged...

The storage is encrypted. The only way to recover the data is booting the current firmware, right? The last backup is a few weeks old...

Yea, it's encrypted by default. No way to recover it really if you don't boot the device into the os.
Also if the battery disconnection doesn't help, try disconnecting different parts that can be disconnected, like the screen, changing port, cameras etc. One at a time.
As a last resort will be to try to bypass the battery or change it.
I had something similar. I plugged it in and left it for several hours (I think about four or five) and then it turned on.
Mine did NOT vibrate every few seconds though like yours but maybe worth a shot.
Good luck and hope you get it working!
It was the display. Had it replaced and now the phone is working fine.
Thanks, guys!

I accidentally dropped my ROG 3. The screen had no scratches or any cracks at all, but the screen had no display. It's totally black. I can hear the sound and the vibration when I hold the power button. No charging LED lights. PC could not detect the phone. Thanks for this post. I need to replace the screen, and it's really expensive.

Redmi note 8 power button error

So, few weeks ago my phone was suddenly turned off and stuck in boot mode ( Redmi logo and reset again ) for almost an hour. I thought it just a random error because overheat etc. so im not really care about it because it fixed by itself.
Yesterday, i got that error again for 6 hours and at some moment i can successfully boot the phone. When i try to touch the power button, the power button suddenly keep pressing itself until sometimes the phone reboot again. Is that normal to get that kind of error? is it just a random error or is there anything i can do to fix the problem? thanks

S8 Hard brick?

Hey all,
While I was watching a video 2 days ago, the screen started to glitch and the phone shut itself down. I tried to restart it by holding [power]+[vol up]+[vol down]. I got stuck in the boot screen, then it shut down completely. I tried charging it but it didn't work. I left it for several hours and tried again, this time it started to charge the battery. I immediately tried to boot it. It booted normally but froze at the home screen, and went black again. Now, I get no response when I plug it to my computer, I can't get into download mode, and it doesn't the charge battery.
I was using the latest Havoc OS if it helps.
Any help would be appeciated.

SOLVED Post update infinite bootloop, restarts before fastboot menu

Hi guys,
one day after some minor update (don't know if it's related) my Redmi 9 Pro started restarting while on the table. I was able to open fastboot, could scroll between options via volume buttons, but couldn't confirm anything with power button. It kept restarting every cca 6 seconds.
After several hours of restarting the battery died.
When I plugged the charger, the phone started restarting again. But now, I cannot even acces fastboot. It restarts before the menu appears.
I didn't do anything with the phone, only updated official actualizations. I have no warranty anymore, its 2 and a half year old.
Any ideas? Thank you!
SOLUTION: After a few hours of googling I found a tip to push power button 10+ when mi logo shows up. It helped.
