Test the Power Switch Connector

Symptom : Can't power on by pressing the front cover button

Possibilities : MBO, PSU,Power Switch Cable

The question is how to test the power switch cable if it is working. Actually, we short the 2 pins at MBO where these 2 are connected to blue and white connector by using flat screwdriver. After shorted, it's still no power. Then, we can be sure MBO and PSU problem.

note: If the 2 pins were shorted, it can power on itself Then I would say MBO, and PSU are working fine except the power switch cable.

Mostly of Acer Model desktop are using blue-white for power signaling
