Bug#574805: powertop: Powertop reports incorrect wattage
Hello, Just for the record, I get the same problem here with powertop 1.13 on an HP 6730b laptop with the Squeeze's 2.6.32 kernel : PowerTOP 1.13 (C) 2007 - 2010 Intel Corporation Collecting data for 15 seconds CnAvg residency C0 (cpu running)( 4.4%) C00.0ms ( 0.0%) C1 mwait 0.0ms ( 0.0%) C2 mwait 0.9ms (13.5%) C6 mwait 2.7ms (82.1%) P-states (frequencies) Turbo Mode 4.0% 2.40 Ghz 0.1% 1.60 Ghz 0.3% 800 Mhz95.7% Wakeups-from-idle per second : 456.3interval: 15.0s Power usage (ACPI estimate): 1.1W (52.2 hours) Top causes for wakeups: … Whereas another small omn tool is showing : BAT0: -93% 11.5W [4h24'] There seem to be about a 1/10 ratio.

My last post is wrong. acpitool is right. i am sorry. I should learn the basics in physics. Since acpitool reports the value in miliamper it has to be multiplied with volt (which is 20 on my AC adapter) to get the usage in watts. signature.asc Description: This is a digitally signed message part.

This seems to be an acpi problem, since acpitool reports the same wrong value. ~$ acpitool -B Battery #1 : present Remaining capacity : unknown, 99.33%, 00:00:00 Design capacity: 5616 mA Last full capacity : 5816 mA Present rate : 2289 mA --- WRONG Charging state : Discharging Battery type : Li-ion Model number : 42T4647 Serial number : 2487 So maybe this isn't powertop related. signature.asc Description: This is a digitally signed message part.
