I have a 9600 and an 8600. Both machines work fine. Both machines have brand new PRAM batteries. Both machines require the power button to be pressed twice to turn on. I don't get it. You press it once and it turns green and sounds like its powering up but no video. Press it again and it shuts off. Press it once more and it boots normally. Anybody know what the problem might be? Once it powers up the machine works perfect. I have tried switching out the ram and moving them around but seems like it work fix it but then do it again later.
