Comment(by mchua):

 Thanks to cjb for help writing up this test case!

 |Test case|

  1. Take 2 XOs running the latest build, and make sure they have fully
 charged batteries in them and are plugged in.
  1. Mark one of the XOs as "Extreme! Power! Management!" On this XO, turn
 on Extreme Power Management (using the sugar-control-panel GUI, go to
 Power, then check the "Extreme..." checkbox). Don't do anything to the
 other XO.
  1. Run olpc-pwr-log in both (see
 [http://wiki.laptop.org/go/XO_power_draw#How_to_use_it howto use olpc-pwr-
 log]) from within the Terminal Activity (this is important; if you run it
 from the VT, the XO will not suspend).
  1. Close both XOs.
  1. Unplug them. Wait for batteries to run down. (This may take multiple
 days.)
  1. When they've run out of battery, plug the XOs back in, turn them back
 on, and recover power logs from both.

 Test pass criteria: The XO marked "Extreme! Power! Management!" should
 have a substantially longer battery life than the other one.
