Power button led

[scowler1]

So I just built a ryzen3 pc on an asrock B450m Pro4. I notice the power button led stays on after I shut down. It stays on unless I switch off the PSU. Other than that it's perfect.

Well....I'd say it's either a faulty switch....it's wired wrong.....or it's supposed to be that way (tend to doubt this).

If it were me...I'd probably leave it alone unless I was really bored and had lots of spare time.

"Wired wrong" sounds right. Go to the Front Panel header at lower right of your mobo and check some connections. Usually there are two wires (often in one connector) for the PWR SW (Power Switch) and they may not have any polarity marked. BUT they MIGHT have polarity markings. Then there are another two (likely) for the PWR LED and those WILL have polarity markings. Now, compare those wires with the pinout diagram of the actual mobo header and make sure the wires are all plugged into the correct header pins.

You might be right about a faulty switch, The wires match up with the diagram from the motherboard manual. Have a look.
