What power supply do you have? More than 30 watts?
Feels like the motherboard sees power but it’s not more than the laptop users to be aktiv. I have that kin of behaviour when I try to charge with a 20w charger.
Try charging it while it’s powered off. Than it doesentbuse any power but can charge.
Try without the expansion cards on every slot.
Even sold/ repacled my MacBook Air with/for it :D
