My laptop is turning off, what should I do?

Question

laptops

Good afternoon, dear ones! My laptop turns off, I took it apart and cleaned it from dust ... in the disassembled state it lies on stands, it can work forever in BIOS, it doesn’t turn off when it boots from Victoria ISO, but I couldn’t check the HDD, the program didn’t find it. When you try to boot from USB and install Debian shuts down, when you try to boot from the HDD, it comes to the Debian console asking for the root password - it turns off. What to do? Tell me please.

Answer 1

Boot from an image that has programs for testing iron like AIDA.
Perhaps overheating under load or memory glitches for example.
Need a load test.

Answer 2

In BIOS change AHCI to IDE. If Victoria still does not find the hard drive (is it visible in the BIOS?), replace the drive.

Answer 3

memtest from bootable media and overnight. It will be cut down within an hour - overheating.

Answer 4

1. Did the laptop turn off spontaneously before it was cleaned?
2. Did you just remove dust from the cooler during cleaning or did you remove the cooling system?
