I have a Dell Studio 15 laptop.
It has an ATI mobility radeon graphics card using the opensource drivers It is running ubuntu 10.04
It runs for a while (10-20 minutes) and then turns off.
acpi -t shows the cpu temperature slowly rising until it turns off.
acpi -c shows two cooling devices both set to 0 (off)
I'm worried that this is damaging my laptop.
Is their a way to force the fan to turn on any other way to solve this problem.
I logged into the Bios to see if there was any way to force the fan on, while it was in the bios screen the computer turned off. Does this suggest its not a ubuntu problem?
I tried running ubuntu 10.10 from a live cd, but still no fan, I turned it off when the temperature got to 95 degrees.
Installed windows vista on it and still no fan. I'm guessing it's a hardware problem at this point
