One day I had some troubles with my computer. Sometimes it crashes both spontaneously and sporadically. I thought it was because the CPU’s temperature was to hight. So here is a command line to know more about the CPU’s temperature on linux (I’m using Ubuntu 9.10)
cat /proc/acpi/thermal_zone/*/*
But this line shows me that the temperature of my CPU was completely normal. I think that my computer has some power problems, but impossible to discover the cause of crashes. Fortunately, it seems to work now…
