Just an FYI for anyone reading this:

For light use, especially on a laptop even on mains power, I usually 
switch to the 'Powersave' power governor. It's easy to switch governors 
now via:

  <alt>+f2
  power govenor

then select from the list.

If you want to explore this area a little, try installing the cpufrequtils
package (it's tiny) and do:

  $ cpufreq-info

There's an interesting read about Linux power management here:
