When I use an external monitor on my Thinkpad Yoga the machine freezes when going into "display off" mode in Windows 8.1.
The lights on the keyboard still lighting and the screen is of course off, but when I press any keys and moves the mouse the machine is doesn't respond at all. Also the fan increases in speed and noise.
The only way to get the machine to work again is to do a reset by holding the power button for some seconds.
Anyone have a solution to this problem or have experienced the same problem?
