Okay, so I'm having some issues with my ibook. It's an ibook g4 1.2 GHz and 768MB DDR SDRAM. Basically, when it wakes from sleep its taking super long and I get that spirally thing for like 15 seconds...or it doesn't wake up at all and i have to close the lid and open it again. Also, sometimes I put in my password and it clicks right back into sleep mode. Also, it seems like my applications are getting slow. on my old notebook, i would have wiped out windows and started over. any suggestions? is there a program I can use to diagnose problems??
