Hep Dead Color Classic

Submitted by mikow on September 19, 2005 - 12:24am. 680x0 Macs and Lisa

hi my friend just gave me a color classic. However its dead. I am sure the power switch was on, because when the motherboard was removed, the fan turned on and the drives made noise. I changed the pram battery with a new one. Anyone have any ideas what could be wrong with this thing. Thanks Mikow Willson

do you have a keyboard?

Submitted by dankephoto on September 19, 2005 - 1:12am.

Have you tried to start it up using the keyboard "power" key? It won't start unless you use that (and of course with the power switch on the back "on".)

CC startup

Submitted by grannysmith on September 20, 2005 - 7:23pm.

Unless you intended to begin a Mystic upgrade, the logic board switch may have been a tad premature. If you go to the Colour Classic forum you will find at least a couple of recent posts about the same behaviour. 'Same', that is, if your machine had been off the mains supply for a length of time before you tried to start up. Replacing the backup battery should be almost a reflex action when you get a second-hand machine, unless the old one tests at 3.5V or more in circuit (3.3V in circuit is the break point), so that was not wasted effort.

Then, if the CC doesn't start up with soft power after switch-on behind, leave it switched-on for anything up to 24hr before trying soft power-on again. To the other Macs that profit from this because they need 5-V trickle power, I can now add the IIci.

Toggle that switch...

Submitted by classic_macster on September 21, 2005 - 12:11am.

Sometimes, rapidly toggling the switch on the back of those old compacts have brought them back to life. It's helped me several times.
