    NUC5i7RYH CMOS battery / time resets / no bootable device




      I have an NUC5i7RYH which has woked perfectly for almost exactly 2 years. All updates have been applied. It now has these issues.


      1. First boot in the morning and I get the following.


      a. A message "No bootable device" (although not every time). Sometimes I have to powercycle the device several times before it will boot.


      b. The clock time on starting Windows 10 has slipped back by a few hours.



      I have replaced the CMOS battery twice (I thought maybe the first one was also defective). No improvement.


      If I do not unplug the power overnight, then it boots normally.
