And the only option is to restart pc holding power button

moreover when I restart sometimes it freezes just on disc or user pasword entering window

but usually in random moments when using various machines,

any hints on downloading some useful drivers to eliminate this issue?

I would start with trying to get anything from logs. In dom0 you can try sudo dmesg -W and see if anything obvious jumps out at you. We’ll need at bit more information as there are countless reasons a laptop will freeze/reboot.

I’d guess there’s a hardware issue, perhaps SSD or memory. I have t470 and t480 and no issues. Is dom0 kernel 6.6.63 ?
