Last Friday (May 19) I posted a note about a backlight problem I was having with my 500 MHz iBook. Several persons correctly determined the problem and gave the part (and where to get it) that needed to be replaced. I just finished replacing the "cable with reed switch" (I only had to disassemble the iBook twice while putting it back together to correct mistakes). The backlight now works with the screen at all angles! I also upgraded the 10 MB drive to 40 while at it. Total cost including the drive: $70 plus shipping. I do not need to throw the old iBook away and my daughter has a useable laptop. Thanks for everyones help - a great group. Steve Stuckwisch
