Hi
>From this mail thread, I see a result format like this:
Power est. Events/s Category Description
8.18 W 100.0% Device USB device: Yubico Yubikey II (Yubico)
8.13 W 100.0% Device USB device: Integrated Camera (Chicony
However, when I use powertop on my Ubuntu laptop, I can't get the first column (8.18W, etc.). I use the commond "powertop --calibrate ", while my laptop in discharging mode.
I can't find the solution in README or website, could you help?
Best Regards ☺

So, I just upgraded to 3.11.5, and see things like this below. Can alsa sound really take 10W when I'm batteries?
Let me put it another way, it just cannot be correct. Full power use is 15W and if you removed 10W for audio (I'm sure that's wrong) and 3W for wifi (that may be correct) it means my quad core laptop is running at 2W with the screen on?
Not possible at all.
So there has to be a bug in powertop 2.4 USB device power calculation.
For what it's worth, I got the data below right after running powertop --calibrate and letting it go through a full cycle.

The battery reports a discharge rate of 15.1 W The estimated remaining time is 4 hours, 53 minutes
