when i turn on my powerbook the brightness is as bright as it is when you turn the brightness all the way down to the last notch (barely visible, only if theres total darkness and you tilt it right, can you make out whats on the screen). When i push the brightness buttons they go up and down but it doesnt do anything to the actual brightness! What happened? what do I do? (i know i can use an external screen for now...) I tried restarting, etc etc etc. what else can i try?

Call applecare. Might be your backlight inverter.

And just to confirm, the Brightness slider in System Preferences -> Display doesn't visibly adjust it, either?

was your powerbook bumped or banged in any sort of way?
does anyone know where the display inverter is located?
does the screen blank out ever?

After two to three weeks my 1.67ghz 15" screen turned into a seizure inducing strobe light. :( It happens. That is what applecare and warranties are for.
