I am using Power Book G4, 1,67MHz, 2G RAM. 1. The light at the connector of power supply to my comp has gone off. I was in yellow color. 2. I need to reset the time every time I on my comp. It starts with 12.00 am 01.01.1970 3. I need to wait for about an hour or two after my last shut down (5 hours of operation in previous session) . 4. When I am watching youtube, seems like the image always come after the voice, and lagging. Thank you.
