G3 desktop looses clock with good PRAM battery

Message #1 - Posted 2006/11/29 - Speardancer

OK, checking out there if anyone's seen this, and even better, has a fix for it.

I have a G3 system I'm putting back together, and despite the fact I've put a new PRAM battery in (one of the 3.6v lithiums) it loses it's clock (and other related ) settings when I remove power. (battery is verified 3.6v )

This is the second time I've seen this on a G3 system, and I never figured it out last time either.

I've zapped the pram, and everything else I can think of, anyone have a helpful hint?

Should a NEW battery not read nearer 4.0v? I replaced one in a Bondi blue iMac which was reading 3.6v yet it produced the symptoms you describe.

Reverse the polarity of the neutron flow.

But don't cross the streams!

No, 3.6v is correct for the battery in this system. Other systems do use other batteries tho.

And yes, battery is in right, unless A) the socket is in backwards and B) this system is different from the other 3 of the exact same model I've gotten going.

I was suggesting that a NEW 3.6v battery checked with a multimeter should, I think, read nearer 4.0v. I was trying to imply that although you had fitted a NEW battery it may be faulty.

So you're saying that a battery that reads at precisely the voltage it's supposed to is faulty?

Highest voltage I've ever read on a 3.6V pram battery is 3.64 and that includes checking many a new battery.
