Computer: 2.2GHz "Santa Rosa" MBP running 10.5.6 Not functioning: -LED backlighting -Left USB port -Audio out port -Airport card -Built-in speakers The computer is no longer under warranty so I disassembled the laptop, checked all the connections and everything seems to be in order. I also swapped out the RAM for the original sticks. The laptop boots up and functions normally aside from the issues above. Any suggestions or words of wisdom? Thanks.
