Hi,
I have used this laptop for the last couple of years but the overheating problem is quite recent, both in linux (ubuntu dapper) and windows (doubleboot). I'm not sure how serious the problem is as I dont know what a "normal" temperature is supposed to be but well here are some indications:
1. cat /proc/acpi/fan/FAN/state always report that the fan is off. sometimes it seems to blow some air but never very much. Is there a way I could test if my fan work properly without using toshset or lm-sensors as these tools rely on apm and this laptop only support acpi?
2. the temperature never goes under around 65C and can go as high as 95C when compiling. Windows does a little better on that but not that much.
3. my hd is quite hot (Hitachi 7K60, 7200rpm) and it "could" be a factor of overheating but I still don't remember such problem at the beginning. But hddtemp reports the temperature of the hd around 40C which seems fine to me, isnt't it?
4. I was quite surprised to see that the trip points are that high! (see under) could you confirm me it is a normal setting? critical at 119C seems *very* high no? shouldn't it be "critical" before? ;-)
5. Oh and finally could it come from my powermanagement settings? (see available ones under...) I am using "ondemand". userspace was selected by default but I changd this setting when it got too hot. What is a good setting for a laptop? userspace use powernowd right? but what's the point of it compared to the kernel governors?
Thanks in advance for your hekp and sorry for the long email :-)
