Hi! I'm still no settisfied with the energy consumption of my iBook2.2. This time I measured the energy spend during sleep mode. When I enter sleep mode from MacOS X the battery will go down by ca 13% in 24 hours. When I enter sleep mode from Linux (snooze) the battery will go down by ca 25& in 24 hours. Hey, that's a factor of 2. Not something easily explained by mearsurement errors. Any hints what I can do? Martin
