Hello, I have 600MHZ G3 IBook running Tiger version 10.4.7. The battery iocn shows that the battery is fully charged. When I unplug the machine from the charger, the machine functions for about 10 minutes and then completely shuts down. I have bought a replacement battery from OWC, and I have zapped the pram. Any suggestions? Thanks, Jack Law jlaw51 at verizon.net "Victory means exit strategy, and it's important for the President to explain to us what the exit strategy is." Texas Governor George W.
