This problem has prevailed since I got my NUC six months ago.
During that period I have been switching my keyboard and mouse,
and have tried several Linux distros such as Mint 16-17 and Ubuntu,
and whatever kernel updates has occured for the past 6 months.
I realize now, my explanation in the original post was somewhat
dubious, I should maybe have written "when I reboot from Linux"
since the no-input-deadlock only happens in Windows upon re-
booting any Linux system. It happens consequently, even when
rebooting from a Live USB-key!
I have been able to ignore the problem for so long, only because
I have used Linux exclusively, where everything just seem to
work, but now I have to use both Win and Lin, and have to
remember to do a full shut down from Lin, or else wake up in
Win to a non-responsive system, which begs the hard shutdown
