Run 'powertop' to see why the machine is being woken up when it is supposedly 'idle' Here's my "idle" (sorry, the mouse was the click-to-copy-paste) I sit at watch and its pretty constant. All those timers .... *sigh* The ironic thing is that this, with the clock on the taskbar and the CPU monitor, the latter tells me the CPU is running about 30%. Ironic isn't it?
