If I open powertop my keyboard / trackpad seems to be using 10+ watts of power at 100% usage at all times. I feel like this may be a bit excessive. Is it normal for the keyboard / trackpad on my hardware (MacBook Pro 8,2) to be using so much power or am I just being silly here?

Thanks

10.3 W    100.0%                      Device         USB device: Apple Internal Keyboard / Trackpad (Apple Inc.)
