How to shutdown laptop with kernel panic?

Question

CentOS

Hello!
Caught, on my head, such a beast as Dexp Athena T139.
Honestly, for many years I have been climbing into any unpredictable, but this is the first time.
After installing Centos, I caught Kernel Panic.
Yes, you can google what to do, and for me it's not a problem.
The problem is that he doesn't respond to anything at all.
Keyboard: zero reaction. Touchpad: zero response. The most important thing ...
Long holding the button on: zero reaction.
The battery is built into this shit, the shit itself is under warranty. Is it really possible to sit and wait until it is discharged?
What to do??

Answer 1

Press the power button and count up to 15

Answer 2

Try to
hold Alt + Prt Scr
consecutively with pauses, press reisub
Although
https://en.wikipedia.org/wiki/Magic_SysRq_key
says that it should not work
If it doesn’t help, then wait for discharge
At the first boot, configure reboot in X sec after kernel panic
