Laptop with Slackware overheats!


I am running Slackware 10.1 on an HP compaq nc4000 laptop with 512MB RAM and built-in WLAN (Atheros) and bluetooth (not enabled while under Linux).

I'm running the default 2.4.29 kernel with ACPI (right off the installation disk, no kernel tweaking done) and madwifi+wpa_supplicant to access my WLAN.

Everything works perfectly, except that the laptop gets extremely hot (if it wasn't so messy I could probably fry eggs on the keyboard) and after 3-4 hours operation I worry about breaking something due to heat and shut it down. WHen dual-booting into XP I do not have the same problem.

I thought ACPI would take care of the fan and such in Linux - the fan appears to be running all the time, but the laptop seems to just generate lots and lots more heat while on Linux than XP, and either the fan is moving at much slower speed on Linux, or it's just not sufficient to take out the extra heat for some reason generated by Linux.

Does anyone have a solution as how to get my Linux laptop to cool down? I've googled for this, but probably not been sufficiently precise in my searches to find anything useful yet.

Any pointers *greatly* appreciated before I burn my laptop..

I'm on a HP Compaq Presario X1000, which is not that different than yours i think. I never had enough time to check on the 2.4 kernel regarding ACPI, but i do know that the battery monitor, suspend, and all weren't working untill i upgraded to 2.6.

I have my laptop on 24/7 all year round btw. It doesn't get hot.

My advice, check if there are any configurations for ACPI in the kernel that might be disabled. And try out the 2.6 if you have the chance. You can use my .config as a starting point if you wish.

I'll try 2.6.10 and see if it helps - if I could try your .config I'd be super grateful!

Is it safe to assume that the ACPI settings on the presario X1000 are similar?

Thanks much!

You can give 2.6.11.8 a try if you wish, my settings support it.

And yes, from what i see in the kernel, its the same ACPI settings.. i don't have APM enabled coz i dont think i need it.

Be my guest, ill send you the .config in a min. Make sure to chance the processor type from "Pentium M" to whichever you're using, and follow the kernel guide from the first post, or this one here
