No, no - I am trying to use Nosleep, or Sleepless to prevent the powerbook from going to sleep with lid closed (yes, I know the dangers).
However, in 10.3, Apple programmed the ApplePMU.kext extension to shutdown the computer after about 4-5 min if it's still on with lid closed.
However, Since posting this msg, I found apple stopped open sourcing that particular extension, probably for that reason.
Oh well.
