also: I found an older Dell adapter that precisely matches the 19.5v/3.34a this thing wants but it still cuts off randomly after being on for about 2 minutes, so I wonder what that could be! It also says 4.62a so maybe this has a higher tdp CPU in it that wants that extra juice. I've got the Official OEM AC Adapter™ on order so it better work with that.
Fortunately there's no password on the BIOS so I'll probably put Windows 11 on here.
