For these sorts of methods, you could possibly obtain a vendor-provided instrument that studies on the PC’s standing, together with the precise mannequin quantity and the UEFI/BIOS model. (Such a instrument does exist for Intel NUCs.) Wanting up the help web page and any related UEFI/BIOS updates is way simpler because of this.
