Comment 4 for bug 1603659

Hi,

a plain Ubuntu does not enable USB autosuspend for input devices. Maybe you implemented something like 'powertop --autotune' in your rc.local?

I suggest you install tlp again (it's in the official repos now), start it with

sudo tlp start

and attach the output of

tlp-stat -u

ps. upower is neither a replacement for TLP nor does it save battery power.
