Does CentOS have a "laptop mode"? I'm only using this OS on servers, so 
I never tried laptop optimizations.

Ubuntu does, and it seems to help keep the machine more quiet and cool. 
I also mount local partitions "noatime", don't use 3D screensavers and 
don't enable the Compiz 3D desktop effects. That crap is a distraction 
anyway. Oh, and I also enable CPU frequency scaling.
I'm using Gnome, but these optimisations shouldn't depend on the desktop 
environment. Maybe KDE enables some graphic effects of its own, I don't
