Once again, I have a notebook that won't boot. This one is a PowerBook G3 pismo with dual FireWire. When I try to power on the unit while plugged into the charger, I get nothing. So, I thought, "bad power/sound board." But I decided to try to boot from the battery just for the heck of it. I charged up the battery using the battery port of a clamshell iBook. The battery does hold a charge and I could boot a clamshell off of the PowerBook battery. But when I attempt to boot the PowerBook using the battery, I still get nothing. I even tried to put the battery in both sides of the PowerBook (both expansion bays can hold the battery). So what's up with this one? Thanks!
