Power Button doesn't light up


Does anyone know what I'm doing wrong? I have a Corsair 4000D Airflow case, and its power button boots the PC just fine, but the power button on the case doesn't light up, even after I tried switching the connectors on the pins. Here's a photo of my motherboard (Asus Prime B660M-A Wifi D4) manual along with some photos of my connectors as they're currently plugged in (in the 2 top left pins). It doesn't seem like a major deal, but it still bothers me. Could it be that the button isn't supposed to light up while just in the BIOS? I'm also not sure if it has anything to do with the HDD LED connectors not being plugged in, but the case didn't even come with those. Thanks for any help!

    You're on the right pins. I believe there's a setting on this board in the BIOS, you can search with F9. It's called "When system is in working state". Make sure this is All On, if it's in stealth mode your RGB/LED will be off.

    It looks like the default BIOS settings were already set correctly, so I just finished the build anyway without the power LED--it might just be a defective light or something. Otherwise, the PC works great! Thanks for the help.
