Comment 16 for bug 1495178

Mentioned on 2015-09-25 that I had to install 14.04. on and no problem since.
 It is or something similar is happening again.
 sudo shutdown 3 min brings me to black screen with power off indicated.
 but I come back a few minutes later and power on light is illuminated.
 -pushing it brings a 10 seconds of hard drive activity and then a power lamp is off for good.
