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.
