'''The #1 LED should at least light - even before you power on.''' ''That it doesn't points to the power supply and it's connections to the logic board. I think you need to look backward, not forward for the source of your problem.'' The other LED's should also light in sequence as the machine powers on. IMHO swapping components after the power supply is useless until you know the power supply is working. ''If this answer is acceptable '''please remember to return and mark it'''.''
