[Bug 387620] Re: [karmic] laptop overheats and shuts off -- fans at low speed

[Sanal Krishnan]

HP Laptop DV5200 TX. currently running Lucid Lynx (10.04) Beta
Auto shutdowns when viewing Flash heavy sites

Is there anyway to ensure that fan can cool the processor, or throttle
the processor to reduce auto shutdowns???

Problem since Ubuntu 9.04

sanal at sanal-laptop:~$ cd  /proc/acpi/fan/
sanal at sanal-laptop:/proc/acpi/fan$ ls
sanal at sanal-laptop:/proc/acpi/fan$ 

sanal at sanal-laptop:~$ cat /proc/acpi/thermal_zone/TZ01/trip_points
critical (S5):           85 C
sanal at sanal-laptop:~$ cat /proc/acpi/thermal_zone/TZ01/temperature
temperature:             55 C
