This is BIOS information, they probably want to take care that no performance is lost and define 9 high and one low step. > Also, it strikes me that /proc/acpi/../power only shows C1, is this normal? > On a Pentium D, I'd say yes. > Last but not least: the loading or unloading of the module doesn't have > any effect on the actual power consumption, even with powersave governor > and both cores at 2.4 Ghz (both at 140 W). Strange. 2.4 GHz is still a lot? Have you already searched for a new BIOS, if not better do that first. Thomas
