You can manually change the throttling with something like: echo 5 > /proc/acpi/xxxxx/throttle It works fine on my Asus L3800S (P4). If I want to get a good battery life, I dim the display, and set throttle to 5 or 6 (out of a range of 0..7, where 0=fast). I haven't measured the effect, but I think it extends battery life by 1/3 at least. The P4 in my Asus also does not have speedstep (according to the kernel, when I enabled speedstep in the kernel config). Gwen. -- [EMAIL PROTECTED] mailing list
