I have an Apple LC III. The mother board battery is dead but I don't know what can go wrong with it dead. I looked around inside it and didn't see anything wrong with it except when I opened the hard drive cover and saw there were like line things on the CD looking thing inside the hard drive. I didn't touch it though. How do I clean this and if I do get it cleaned then will everything still be on the hard drive? Is there anything that won't work with the M.B battery dead? When I start it up, It sometimes doesn't boot up, and when starting up, it sounds like it's going really slow when starting. It doesn't even make the start up noise sometimes... When it does work when booting (slow...), it brings me to a happy mac dude and then goes to a screen with a picture of a small floppy disk with a blinking question mark in it... I am desperate to get this working again... Please help!
