okay, I updated to 10.2.6, got all the latest patches installed as well... upgraded to 640MB RAM... now I notice the typing is delay when the PB fan is on... you know the very loud fan... I believed there are at least two to three fan in the 12" powerbook... anyway, when the very loud fan is on... that's when my 12" powerbook is clawing as well... everything become laggy, typing is delay... is that normal or what?
