Hi There,

If you take off the display panel and plug the power supply in (taking care to avoid the power unit) you should see a single green LED just off-centered on the logic board. Press the power button and check which other LEDS light up and turn off.

The order for the LED's:


| | | |

LED 1 is lit up then the Logic Board is receiving power and should be on whenever the power supply is plugged in.

LED 2 will light up when the computer is turned on

LED 3 shows the Logic Board and Video Card are communicating correctly

LED 4 indicates the Logic Board and Display panel are communicating. In this case this will not light up as your Display panel is unplugged.

You should try unplug the SSD and see if the machine powers on
