Clock battery and video?

[karavite]

Hello All,

In the old days when a $8 clock batter died some Macs lost video (talk about a heart attack). Is the same still true?

Reason I ask is my 5 year old G4 DP 1 GHZ started having the screen completely black out the other day (for about 2 seconds at a time). Since then it has not done this and I am crossing my fingers.

I guess this leads to a second question. I checked all connections and they seemed fine, but what might cause a Mac to have video black out like this? Could it be related to the heat in the room (90 degrees that day)? Do video cards often die (never had one die yet). Sorry for a sort of rambling question.

There are lots of things that could cause a video signal to drop out. 90% of the time it is a bad connection, loose plug, or a flaky cable. And yes, heat will often trigger the problem. As for the battery, I'd rank that as a "maybe".
