My Performa 635CD is Being Lazy!

Posted by: Juliet Elysa on 2014-10-16 23:17:26 My Performa has a strange quirk. It seems to be morally opposed to giving system errors with text in them. Either that, or it's just too lazy for words. These errors pop up when I leave the Performa running unattended for a certain period of time. Also, like most system errors, they sometimes appear for no apparent reason. The crashes don't interrupt normal use of the computer - it crashes about as often as most other computers do when they're actively being used. The Performa has been in my family since before I was born, and nearly all of the bomb errors I've seen have looked like this: I believe my Performa runs System 7.5.1. The crashing isn't a huge problem. It's just really weird, and I'm curious if anybody else has (or knows of) a computer that crashes like this. 😛

Posted by: Macdrone on 2014-10-17 00:16:39 My performa 63x's do that. Usually due to dead pram battery. It's a square battery on the slide out motherboard. Also update to 7.5.5 if you get a chance.

Posted by: Juliet Elysa on 2014-10-17 00:33:08 Does a dead PRAM battery have any other noticeable symptoms? Other than the blank bomb messages I don't recall ever seeing anything abnormal. Thanks! 🙂

Posted by: Macdrone on 2014-10-17 00:36:00 No its just kind of quirky that way.   I always noticed it more on waking from sleep on my 638CD.  It doesn't hurt anything but 7.5.5 took away some of the issues.

Posted by: Juliet Elysa on 2014-10-17 01:00:05 OK. 🙂 Little glitches and stuff like that are what make computers most interesting, in my opinion. Thanks again!

Posted by: wilykat on 2014-10-17 12:05:30 Isn't the 630 series the last of low end Macs before 68k was completely retired in favor of PPC?

Posted by: Macdrone on 2014-10-20 19:59:44 Yes.  They were LC 040's and no real expansion.

Posted by: XBHS1997 on 2014-10-22 11:09:41 If you want to replace the PRAM-battery (I think it's a Rayovac 840), you can do this by soldering 3 AA-batteries together. Did that on my 4400/200, works just fine.
