    I have a new to me 15in 1.67 ghz powerbook. I just put a fresh install of 10.5.8 on and all was well until it started randomly going black and putting itself to sleep. It does this whether plugged in or not and requires hitting the power button briefly to light the screen back up but it usually blacks out again in a few secs. It doesnt seem very hot, which was my first thought. Also the battery was holding a decent charge prior to these black outs. Any ideas of what it is would be greatly appreciated.

    obvious things first ,when you did a fresh install did you look in the energy safer settings , as the original settings in leopard are set very very low


    not so obvious restore permissions , and eventually you got a dead pram "battery"

    Hmm, I did try to erase the disk prior to reinstalling the OS, and I think I might have "restored permissions". Can you please elaborate? thx

    I went into disk utility and verified and repaired permissions, There were a bunch conflicting things which got fixed, it seemed to be fixed but now it just started shutting off again :(

    You have the PowerBook narcolepsy, its cause by a faulty trackpad. Install a utility like sleepless, unfortunately, you won't be able to close the computer and make it sleep.

    You can also try Caffeine to prevent your screen from dimming.
