Alienware 17R1 "Plugged in, not charging" or "Not charging"

This problem just happened yesterday, the system appears to detect the battery, but it won't charge at all.

I checked the BIOS and it appears to detect both the battery and the adapter (I'm running the last version of BIOS <A14>).

It shows "Battery health: < this battery performing normally >" and "AC Adapter: < 180W >", but the battery still refuses to charge.

Am I suppose to replace the power jack board or what?
what can I do to solve it?

I'm running Windows 10 Home.
