Update September 28 = A DELL-Cares agent troubleshot and a Windows 10 Reset was performed and seemed to correct the issue.
Hi. I bought a new m15 R4 about 6 weeks ago and it just died. There is something about an unexpected_kernal_mode_trap and then I got a message about an OS_Boot_Failure. Startup repair didn't work. I did a hardware test and everything passed.  It then tried to restore the system to a restore point - which I think was the point when I got the machine - but that failed. I'm basically going through a reset now and it's just slowly backing up my data before resetting - was just wondering if anyone has had a similar prob? Thx ps. while it was working it was good
