Daughters phone is completely dead, will not switch on. Please help

[TylerDurdenK]

I have had it plugged in all night, and tried the following ;
Hold power for 1 minute
Hold power and volume up for one minute
Hold power and volume down for one minute
Hold all 3 buttons for one minute

None of these worked.
I have plugged it into a PC but there is no connection.

Is there anything else I can do?

*EDIT* Fixed it! https://forum.xda-developers.com/showpost.php?p=83649851&postcount=7

Its dead phone. What do you want some magic to turn it on? If it dosnt want to turn it on its dead phone and you cant do anything about it.

You might be right, but in the 20 years of owning mobile phones I have never had one that simply "died" before. I've ordered a new charge port as I think it might be to blame.

Pressing pwr + volume down or volume up won't turn on device.
You're not saying if device can enter to recovery nor fastboot or If your device is unlocked or not or if you have some screen as the logo or if you have some vibration, some led blinking, or if you let it charging with screen on (it must be screen burning) or if device was off while charging...

The phone has no sign of life. No led, no screen on. Nothing.

Well, there is not much you can do here, it could be a damage at the hardware level, probably in the port charger or at emmc/motherboard.
Also the overcharging or the kernel panic produced for some overheating can make that device won't boot.
The only you should try at software level is this https://c.mi.com/thread-1479882-1-0.html

I fixed it! After replacing the charging port it still didn't work.
However I read somewhere that disconnecting then reconnecting the battery connector inside the phone would work so I tried that and it worked.
Phone back working fully.
