I was thinking jumpers and switches but I don't think modern motherboards have that feature anymore so I'll ask, Do you have jumpers on that board?
The MB is only about 2 years old, and I seem to recall a couple of jumpers on it. That said, in all my 22 years of PC building I don't recall there ever being a jumper that tells a MB its in a laptop, and not a desktop. However, it is a good place to start, so I'll open it up tomorrow and get into the manual to see if maybe I dislodged a jumper, or perhaps a switch of some kind.
When I posted this I was hoping someone else might respond and say: "Oh yeah. That happened to me one time too"; and thereby save me some investigating.
I am retired now, and decided to retire from PC building this year also; don't want to keep up with the tech anymore. My most recent acquisition was a gaming PC from Xidax. What a great machine!
