Using powertop to try to see what is using power is a good idea, thanks. I was using a power meter that reads the power being drawn from the outlet by the computer. Readings were being made while I had a monitor hooked up and being used, so video card could not have been inactive. I was interested in idle power draw, so not doing anything (and waited for draw to stabilize after boot, login, etc.). top shows cpus as around 98% idle even when in runlevel 5, but the X11 process is one of the top cpu users so odd that eliminating it would cause power increase.
