I have an older board that will not turn on the power supply (PS). (Yes, I have done extensive troubleshooting and can say the board is the issue.) I can short pins 15 & 16 and the PS will start. So I shorted the wires for pins 15 & 16. This works to turn on the PS. I turned off the PS at the main switch and reconnected the cable to the board and turned the main power back on. To my surprise, the PS did not start. Without turning off the PS, I disconnected the cable and the PS started. I pugged the cable back in and the board started. From an electronics point of view, this does not add up. So what is keeping the board from starting when the cable is connected vs being connected after the PS is on?
I run 24x7 so no need to turn off the computer. I can do a Windows restart without issue, so for now, I just don't turn off the PS. 🙂
