Improving battery life on a laptop

[imported_goku]

I recently found a website that had a very indepth guide on how to improve battery life but I lost it and can't find it so I'm wondering if anybody could guide me to some sites on how to improve battery life on my laptop, it mentioned things like underclocking etc..

This links to a thread more dedicated to underclocking/undervolting the Pentium-M
