Well, my system is turning off (shutting down), and I don't know why. It happened 4 times today. I am using the computer, and then it turns off. Could anyone help me?
The more probable reason is the overheat of processor. So after the next turn off, just go to BIOS, and check temperature sensors. So after the next load of the linux check temperature of LM sensors with:
sensors-detect systemctl enable lm_sensors.service sensors
psensor GUI software. Also read the article on how to setup and check the temperature of the system devices.
Maybe it is overheating?
You can install the program "sensors" from the terminal (type in
sensors and it will tell you how) and check the core temperature whenever you want by typing in
("turning off" suggests that it is shutting itself down and not just cutting out suddenly (as if the power went), which is why I am thinking overheating.. )
