"Instructions"
Do I have this right- your bypassing the switch and shorting the motherboard leads? Seems safer to test the switch with an ohm meter. Less chance of letting the smoke out.
I've fixed an untold number of things by unplugging them and plugging them back in. I think I would start by unplugging the power cord, cycling the switch on the power supply repeatedly, unplugging the connections from the PWS at the motherboard and the front panel on/off switch.
But it seems the elephant in the room is the message he gets: "CMOS Battery Low"
He replaced the battery and still gets the message. The second battery could be dead. Something may have come unsoldered or there might be corroded contacts?
Wonder if we'll hear back from SDF on this....
