Power switch dead LED

I have a new install. The machine is a  I7-1355U 6L - a 6 port router.

The power switch doesn't illuminate. I have another near identical machine - same MoBo but with an I5 processor. The power switch on that machine illuminates bright blue when powered on. The switch on the new machine functions - it turns the machine on and off, but doesn't illuminate.

The machine runs fine using the provided psu. I have a couple of nvme drives installed plus 64Gb of ram. Proxmox and a bunch of VM's run just fine. Just no front panel power indication.

Also, I have the bios to auto restart on power failure, but this doesn't seem to function - on the I5 when I first plug it in it powers sup, but the new I7 doesn't do that.

Do I have a faulty board?

Can the led be user replaced somehow?

Do I need to replace the MoBo?
