Hey all.

I have run into this issue now with boards: Asus P5A, Gigabyte GA-5AX , multiple cases and power supplies.

So the primary symptom is that the computer boots up and works as it normally does. Then after power down, the power button doesn’t work. Pulling the power cord in the back doesn’t seem to fix it. There is only one fix: pull the power cord on the motherboard’s ATX 20 pin connector and reseat it. This usually fixes it but it’s obviously awful.

Anyone else experience this? The most common denominator is that all these are Aladdin 5s, ATX and modern power supplies.
