Hi, I use powertop to monitor my pentium-M Dothan processor (on a Toshiba A80-111) but I always get extremely high power usage estimates.
Cn Avg residency P-states (frequencies) C0 (cpu occupata) ( 3,4%) 1,60 Ghz 0,0% C1 0,0ms ( 0,0%) 1333 Mhz 0,0% C2 5,2ms ( 5,4%) 1067 Mhz 3,4% C3 0,9ms ( 0,2%) 800 Mhz 96,6% C4 22,5ms (91,0%) Wakeups-from-idle per second : 53,1 interval: 10,0s Power usage (5 minute ACPI estimate) : **75,0 W (0,5 hours left)** Top causes for wakeups: 28,7% ( 14,9) X : do_setitimer (it_real_fn) 19,8% ( 10,3) thunderbird-bin : futex_wait (hrtimer_wakeup) 19,6% ( 10,2) kicker : schedule_timeout (process_timeout) 11,3% ( 5,9) <interrupt> : ipw2200 4,2% ( 2,2) <interrupt> : libata 2,7% ( 1,4) wpa_supplicant : schedule_timeout (process_timeout) I can't believe my laptop is draining so much power, where's my mistake? I use the latest bios version. My kernel is gentoo-sources-2.6.23-r with hrt patchset and acpi enabled. The battery is quite old. It last no more than 45 minutes. However I don't know whether it would work better under windows or not. Strangely when the battery reaches 0% the laptop keeps going on for almost 10 minutes! I can't make historical comparisons because I've just switched back to gentoo from ubuntu moreover I haven't used the battery for two months.. Can you suggest me a list of things I should check in order to find the reason of such a behaviour? I'll provide you any information you need. Thank you in advance.
