I installed RAM in my 2001 iBook 500 the other day. I had taken the two screws off the aluminum chip cover when the CD slot opened unexpectedly. (Everything was off and unplugged, the battery removed.) Later I looked where I had put the screws (right where the CD slot is), and there were three identical screws. I ejected the CD tray and couldn't see any missing screws, although one of the tray slides is just a little loose now. Any idea where this extra screw came from? (Whew, no puns! That was a tough challenge.) Jeff -- Jeff Newman LawProse, Inc. The White Oak Independent <http://www.lawprose.org> <newman at longview.net> <newman5608 at earthlink.net>
