Hi,

I have a Toshiba Satellite Pro L510 laptop w/ dual boot Slackware64 and Windows. On Slackware, there seems to be a fan problem. The fan doesn't start until it reaches 90C and then continually keeps on blowing, with temp steadying somewhere around 70-75C(w/out video/any compiling going on). If I try to compile something which takes a long time, say the kernel, the temp shoots up to 100+ and it ultimately shuts down. I have tried other distros(arch, fedora, ubuntu) but only ubuntu 10.10 seems to get the fan working correctly with a steady temp around 45C. Windows also works fine. I really want to try other distros but the heating problem is very discouraging.

Please advise me how I can find the problem.

Here's the spec:
Toshiba Satellite Pro L510
Intel Core 2 Duo
ATI Mobility Radeon HD 4500
Realtek Wireless 8192SE
3GB RAM

Thanks.

so if you would run distributed computing project (100% cpu usage all the time) fan won't be able to cool cpu down? That makes cpu temperature more stable, but high!

Try also searchin bios for fan settings.

Ubuntu is debian based try the real Debian as it uses less resources than Ubuntu.

yea toshiba laptops have always been real strange
i think the fix is the boot parameter
acpi = copy_dsdt

there is also this project

i have read where people use this on L510 also

Ok, thanks. I will try out both the fixes and get back to you.

Regarding Debian, I tried its liveDVD and I couldn't really find any improvement in the fan situation. From what I've read it is in all probability a BIOS problem(or more precisely, BIOS<->Linux interaction, since Windows works fine).
