SO the unit had a dent in the top rear. The Internal fan and the radiator are very dusty and dirty. It does work, but will not boot to an NVME M2 SSD.Update Well it seems that this unit will not take any other SSD as a boot drive other than what came with it. In addition It will not allow me to get into the Bios.Update I tried everything on the internet From HP and beyond and nothing I do will open Bios. and The only drive that will boot is the 240 that came with it. Returning as this is unacceptable.
