Laptop returns, cpufreq actually works

My Dad’s really awesome sometimes. In a previous post, I talked about how my laptop’s screen cracked due to a friend’s drunken behavior. Well, my Dad did me a favor and swapped the old HD out of my broken laptop and put it into the new one I got. So now I’m running Linux as if nothing broke.

Here’s another crazy thing… I thought my laptop didn’t have cpu frequency scaling support, but I was actually wrong. It’s just that I didn’t have all the kernel modules I needed loaded. It turns out I can scale the CPU on this laptop from 400mhz up to its max of 1.7Ghz! This is awesome because power consumption goes way down, laptop stays cooler, etc.

Plus, someone wrote an excellent piece of software to do this scaling automatically depending on load and remaining battery power. Temperature readings still come in as 0 degrees celsius, but I decided temp readouts are unnecessary anyway. The BIOS does a good job managing the fan. Yay new laptop! Back to work on my paper.
