-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Richard
I assume you've got the cpufreq-utils installed and running. What you can do is (as root): $cpufreq-info This will give you some information about your CPU. It looks something like this: cpufrequtils 0.4: cpufreq-info (C) Dominik Brodowski 2004 Report errors and bugs to [EMAIL PROTECTED], please. analyzing CPU 0: driver: centrino CPUs which need to switch frequency at the same time: 0 hardware limits: 800 MHz - 1.87 GHz available frequency steps: 1.87 GHz, 1.60 GHz, 1.33 GHz, 1.07 GHz, 800 MHz [snip] The most interesting part is "avaiable frequency steps". Now you can change the upper bound to a lower level with $cpufreq-set -u 800000 This will set the upper bound to 800MHz. This means you're CPU can't get "faster" as this. I've you need more, you simply change the upper bound. Another battery saving tip: set the powermode of your GPU lower and you will get another 20-30 minutes ;) I hope this will help. This is my way of throttling the power. Isn't as nice as the power managment guide says, but it works :-) Richard Watson wrote: > Hi - I've been setting my laptop for power management by following the > Power Management Guide and have successfully got cpufreqd running. > However the CPU still gets hot on large compiles.
