I'm only seeing a peak of 1% CPU with your config which is making this slightly harder to narrow down, but I think the custom power_menu module is causing the spike. Can you try commenting that out and see if that reduces the CPU usage for you please?

Got it. A recent changes to scripts accidentally moved the sleep call for the script interval out of the polling loop, so scripts were being polled as fast as your poor machine could cope. The tooltip on the power menu module was doing it for you.
