Ive also noticed this problem a lot , i dont even use acpi on my T40p its worthless , dont use windows anymore on it but im sorry to say that it has no less than 2+ hours extra on the battery , this i considder as lousy centrino / acpi support it would be cool if this could be fixed , there shouldnt be a reason why one should use windows on it
