Memory-128 Processor-PowerPC G3
Hi
Glad to hear the PMU reset restarted the machine.
128 RAM is too lean for OS X, especially Jaguar and later. Assuming you have a white iBook, then you can increase the RAM to around 640 for approximately $60 to $100 or so. If you have a Clamshell model, then RAM can only be increased to 256, which is still lean for OS X.
Which model do you own?
