Front panel wiring
Last response: in Systems
Hi,
Have a gateway desktop approx 2-3 years old.
The unit will not power on.
When on-off button is pressed, the led on button flashes but does not stay lite and the unit doesn;t power up.
Took out the PS and shortened pin 15 and 16 and fan goes on. Fan does not go on when in the unit.
The small board on the power switch has four wires, white, white, blue, green going to Motherboard. Should I try and short two of the wires?
Thanks

One pair of wires is for the switch, the other is for the power led. The header where these connect to the motherboard should be labeled as to which is which. Find the power switch one, remove the connector, and try shorting it quickly with a screwdriver or something. Just touch both leads at the same time and then pull away.
If that does not work, it is likely some form of motherboard or PSU failure. Just because PSU spins up separately, does not mean it works entirely. It has different sections, only one of which is tested by your method.

HI
Thanks for the response. Had the PS tested and all connectors work correctly.
Although the motherboard is only labeled with the designation "Front Panel" I did short the power switch trying both sets of wires (blue/white and green/and could only get the LEDs to lit, but no power on.
Appears to be a motherboard problem..Unfortunate
Thanks for the help
Rob
