I think that it's not overheating, because CPU temperature is 60 C on compiling (I have used this CPU on 90 C!).jnbek said:is it overheating?

I've experienced similar things (and heard of others with the same problem): when compiling something big (e.g. world or a large port) on my netbook sometimes the system just instantly cuts power.SirDice said:That's usually a result of an overheating CPU.

# kldload coretemp
if necessary) and then periodically do # sysctl -a | grep temperature
) and suspends compilation processes for a while when the temperature gets beyond a certain treshold.Perhaps. That would depend on whether it's ACPI that cuts the power, or the system hardware itself.prp-e said:I guesskldunload apci

I've cleaned my laptop's fan, and I use an external fan.mav@ said:If the laptop is not very new, make sure you've tried to blow hard into the cooling output opening. Sometimes it evokes a significant cloud of dust from the cooling subsystem.

sysctl dev.cpu.0.freq_levels
. (Someone please correct me if that's not right). The output will be in pairs like: xxxx/yyyyydev.cpu.0.freq_levels: 2400/35000 2000/28000 1600/22000 1200/16000 800/14000
