I have the same problem with my Mac Portable but I havent had much time to tinker with it.

Have you replaced the 9 volt battery? I'm wondering if that might have something to do with it in some strange, phases-of-the-moon way.

But they all seem to have bad hard disks (Apple 40SC internal) -- if the drive is connected at power-up, it makes a tick-tick-tick noise, the screen flashes, and it repeatedly plays interrupted Death Chimes until I turn it off. The drive never actually spins up.

So, anyone got any ideas about what to do with them (besides drop-kick 'em into a swimming pool)? Is there some goofy reset I can do, or a bad fuse somewhere to replace?
