Hello, may I please again ask for your help regarding this issue: I notice, with 2.6.25, that my T61 runs rather quiet on battery while in AC mode the fan runs far often, if not all the time. With recent powertop I could find out the most likely reason: (Kernel 2.6.25) AC: Your CPU supports the following C-states : C1 C2 C3 C4 C5 C6 Your BIOS reports the following C-states : C1 C2 C3 Battery: Your CPU supports the following C-states : C1 C2 C3 C4 C5 C6 Your BIOS reports the following C-states : C1 C2 C6 Powertop then shows me it's actually using the processor states as listed as reported from BIOS. So obviously it doesn't use the low power state C6 when on AC while it does on battery. I already tried all reasonable as well as non reasonable BIOS settings to see if that changes something, but no, I can only get it worse in battery mode, but not any better in AC mode. Is it possible, maybe with some slight tweaks (setpci...), to convice the kernel (or BIOS?) to also use that C6 state when in AC mode? I would love to!
