Is it possible to upgrade to the powerbook keyboard with backlighting? Could I just drop it in and it will work or is there something else that is needed?
I was thinking the same thing but I think the backlight keyboard would be really cool, even though functionality wise I don't need it. I use the home keys and don't look at the keyboard.
I'm almost positive that the backlit keyboard also makes use of a seperate power tansformer located within the PB. PB's without a backlit keyboard do not have this transformer, so you'd have to put one in, which means cracking open the case, voiding your warranty, and other unnecessary/dangerous/costly issues.
I've taken my Powerbook apart to upgrade the hard drive, and there are two cables that I disconnected when I took out the keyboard. I assume that one was for the keyboard, and one for the backlighting. The only way for you to know if it'll work is to give it a shot. If your powerbook does have this extra connector for the backlighting, then it should work. But there is a chance they didn't include it, or left the ambient light sensor out.
