So I installed OSX using the 10.6.3 retail CD and the nawcom boot CD, now I'm on 10.6.6. Most things are working well, just noticed a big problem.

When I boot on A/C power, no problems. When I boot using battery power, I can get to the desktop, and just when battery icon in the top right corner loads, the whole screen goes black, almost like it's sleeping - but the fans are still on. It seems like the screen is trying to dim, but since I turned off the "dim screen on battery power" option, that doesn't make sense.

If I boot with A/C power, then unplug it to switch to battery power, the same things happens.

If I boot with the nawcom boot CD on battery power, I can get to the OSX desktop, no problems.

I installed VoodooBattery, VoodooPower, but I'm stuck. I will say I had to delete the sleepenabler.kext, as that gives me KPs. I'd love to get sleep working too, but the battery issue is far more important.

Thanks!

Well, I think I got it sorted. Not sure if there was a conflict between VoodooBattery and my graphics or what, but using AppleACPIBatteryManager seems to have done the trick, after deleting VoodooBattery.

Not 100% sure that's the fix, but it seems to be working. Hope that helps someone else at some point.
