Hi! > What hardware are you using? Is it a laptop or desktop pc?
I's a Dell Inspiron 9400. > Few general suggestions: > 1. update your bios to latest version. > 2. Try to load motherboard-specific acpi module (e.g. asus-acpi for asus > notebooks, or acer-acpi, or ...) I think there isn't any for dell. Correct me if I am wrong, cause I'm not at the laptop right now. Patrick
