• Verify power supply
 
LED #1 + LED #2 = Power available, and system is powered on.
 
If second LED is not visible when power button is pressed:
 
• Verify power button connection to logic board
 
• Verify power button functionality
 
• Verify cable connection between power supply and logic board
 
• Verify power supply
 
• Verify logic board
 
LED #1 + LED #2 + LED #3 = Power available, system is powered on, and video card found.
 
If third LED is not visible after power on:
 
• Verify that MXM video card is seated properly
 
• Verify logic board
 
If no lights are coming on you need to replace your power supply. A trickle charge is sent from the power supply to the first LED. If the first LED is not lit the power supply is not working.
