No diagnostic #1 LED on logic board
When the computer is plugged into the wall the diagnostic LED #1 is not lit. If I leave the computer plugged in for a period on time, usually overnight the LED1 light comes on and the computer starts and runs normally.
Based on the service guide, I replaced the power supply with a new one but continue to have the same problem. I have checked the cables into and out of the power supply unit carefully and they seem good. The next step seems to be replace the logic board.
- Any suggestions other than replacing the logic board?
- Anything I can do to confirm it is the logic board?
Is this a good question?
