I tried that - no help

I made some other observations - I think the total power consumption is just
much higher and somehow powertop tries to find a a victim to blame.
SOmetimes it says it's because of display backlight even if I put it to 5%
brightness.
Even more
WHen I plugged an usb dock/hub with ethernet and usb keyboard it started to
report several Wats ! on keyboard . In other case on usb drive in other case on
ethernet adapter.
