This computer arrived with an open box and zero documentation.  Just the laptop in a box.  I decided to reserve judgement and it worked fine for about 2 months.  Now it’s a blue screen and cannot load windows; the computer asks for your bit locker code, which you have to retrieve from Microsoft. After going through every simple and advanced diagnostic remedy, Windows cannot be loaded from the cloud or reloaded locally.  It cannot even be reset - it freezes halfway through the process and gets stuck in an endless loop .  This is a defective piece of junk and it is likely OEM are selling refurbished or returned computers with intermittent problems.
