Is there a way to get a warning when the computer will crash (perhaps due to heat) or at least read a log file that tells me why?
In the past month, at least twice, maybe 3 times of constant running, my laptop just went blank in front of me, and shut down.
I don't know why. I only know to do a "dmesg" but when I reboot and then run "dmesg", I only get messages that I don't fully understand or which don't seem related to the crash, for example:
