It appears that
upowerd is hogging my cpu time, I killed the process, but it has returned, and is climbing in resource consumption. Do I need upower? can I disable it?
I am using ubuntu Mate 16.04.

From @JonasCz, whose comment was:
Do you happen to have an iPhone plugged into your computer ? If so, you may need to select "Trust this computer" on the phone (or disconnect it), which may fix it: bugs.launchpad.net/ubuntu/+source/upower/+bug/861642
Unplugging the Iphone solved the issue, or was an acceptable answer for me.
This just happened when I resumed the computer this morning. Going into suspend last night I had Power Panel left open. This morning Power Panel was all greyed out and the hard disk light was flashing like a disco light show.
I used these commands:
$ ps -aux | grep upowerd | grep -v grep root 2013 0.5 0.0 349976 7372 ? Rsl Aug11 11:12 /usr/lib/upower/upowerd $ sudo killall -9 upowerd
Of course now
upowerd isn't running at all but that's OK it'll come back with the next reboot. I don't use it much anyway just to check when wireless mouse or keyboard batteries are low.
