I'm sure many people, me included, have damaged or lost little proprietary cosmetic computer parts. I want to sell an old Packard Bell computer, but part of the faceplate is lost. It's purely cosmetic, but I don't want to punch a big hole in the faceplate to use the on-switch. Of course, PB is out of business...and if they weren't they probably would charge $25 for a $.10 part. How do I replace it? It's just an oval button...
