I had a brand new powerbook...was perfectly working for hardly one day, but all of a sudden, when i open it from sleep, the display only comes fro 1 second, and blackens out...i can vaguely see it running in the background, but there is no enough light. I hae tried adjusting the brightness....nothing works...have given it back to apple to check. migt get a replacement...keeping my fingers crosse...any idea why this happened?

The very same thing happened to my Rev A 12" in April. It has gone to Apple twice, only to see the same problem resurfacing.

In the end I fixed it myself: when swapping the harddrive for a bigger one (Damn! Talk about a LOT of screws... ) I found out that if the longest of the nine or so screws underneath the keyboard is screwed in too tight, the display goes nearly black, except for a VERY faint image.

I loosened it a bit, and the laptop has performed flawlessly ever since. (Until I dropped it that is, but that's a different story. Banana-shaped Powerbook, anyone? ).
