I have loaded p4_clockmod, and my CPU frequency now changes with powernowd. It seems to work well. `--> cat /proc/cpufreq=20 minimum CPU frequency - maximum CPU frequency - policy CPU 0 383323 kHz ( 12 %) - 3066590 kHz (100 %) - userspace `--> cat throttling=20 state count: 8 active state: T0 states: *T0: 00% T1: 12% T2: 25% T3: 37% T4: 50% T5: 62% T6: 75% T7: 87% However, I am not seeing any battery life improvement. Any ideas? Thanks fred ------------------------------------------------------- SF.Net email is sponsored by: Tame your development challenges with Apache's Geronimo App Server.
