Hi darlene If you put the iBook to sleep by closing the lid, what happens if you open the lid just enough to awaken the machine? Try it a few times and see if the backlight comes back on. If it does, see if as you open the case further if it will turn off again. It sounds like you're familiar with the history of some of the white iBooks where the display cable could get crimped over and over again eventually making it intermittently fail. -------------------- If my email is short, it's because I'm emailing from my iPhone. iPhone mail www.apple.com/iPhone On Oct 7, 2007, at 10:08 PM, Darlene Hess <d_hess at bresnan.net> wrote: > HELP! > I needed to replace a Optical drive on a 14" ibook (out of warranty, > of course).
