Power Switch

by TheChas In reply to atx power

If you are lucky, all that is wrong is that the push button power switch on the front has gone bad and needs to be replaced.

It might even be disconnected from the motherboard.

If the switch is good, then the circuit on the motherboard that routes from the switch header to the power supply connector has failed.

May not be the problem here but I've just had a case

Where the Fly Leads from the M'Board tot he Front Panel Switch had failed so when you test the switch make sure to test at the switch and again at the Plug.
