I am worried about a fire hazard.
My son has an Acer Extensa 4420-5237 model laptop. It tends to run fairly hot even with a newer version of Ubuntu -- Ubuntu 10.04 LTS Linux. Is there something I can install which will cause the fan to run a little longer or more frequently to cool this thing down?
EDIT: In the end, I found that the BIOS is old, can't be updated unless I install Windows first (which I won't do), and the BIOS is controlling the fan speed instead of the OS (and doing a lousy job of it). The thing is running the AMD K8 chipset. The sensors tell me the temps are running near to high, sometimes high occasionally, but never close to critical. All attempts at running pwmconfig and fancontrol fail because I have no throttle-able sensors due to the BIOS settings I can't change, or perhaps it's just the AMD K8 chipset. In the end, I have decided to dust the thing out with an air duster and then get a laptop cooling fan thing underneath it to keep it cool. Indeed, I found that simply holding the laptop up to a room fan causes the temp to go down to 129 degrees Fahrenheit and remain in the 130's for awhile, so it's a quick fix.
