I'm an beginner/intermediate Linux user running Fedora Core 1 on a Dell Inspirion 5150 with the standard 2.4.22 kernel that comes with this distro. I have acpi enabled, and it runs great under gnome (kde gives me weird values, but that's just kde). I would like to get the suspend and standby features to work. Both features ran great on my laptop under Debian woody without any configuration so I know its quite possible on this laptop. My plan is to grab a fresh 2.6 kernel and apply the acpi patches. Before I start, I was wondering if anyone had tried something similar. I also notice that windows gets significantly better battery performance than Linux when they are both under the same conditions. Any tips on tweaking Linux for using less power?
