If like me, you are thinking about extending the EeePC's battery life by turning on CPU frequency scaling support, I can tell u now to forget about it. It doesn't work.
After turning it on & testing the temperature & battery life, I am very sure it does absolutely nothing for the EeePC. In fact, the only thing it did was make the system lag every time you click on something, this is because the CPU will scale to max for almost every single task. The system takes a second to scale, this is what causes the lag.
After reading in various forums & opinions on it, it's clear that frequency scaling does not improve the battery life or thermal performance of the EeePC 701 which uses an already sluggish Celeron M. In some tests, it even makes things hotter.
So, I've reverted to running the system at the standard 630Mhz with no scaling. I'm currently averaging about 170 minutes per charge with wireless on, which is not too shabby for an 8 month old battery.
