I have a new surface pro with the clip on keyboard for work. It's nice if you want a tablet, but I use it as a desktop 99% of the time. I have two monitors, keyboard, and mouse plugged in via the official Microsoft Surface dock, which plugs in via a thingy on the side of the surface. I have it configured to turn the display off after 10 minutes and never go to sleep.

If I leave the computer for half an hour, then come back and hit a button on the keyboard, the external monitors don't turn on. Nothing seems to turn them on, including the surface power button, mouse, anything. If I open the surface keyboard up it shows on the surface screen instantly. To get the external monitors working I have to open up the surface keyboard, I tend to try unplug and plug in the power, try the power button, and eventually it wakes up. After a bit more messing around the external monitors wake up.

Anyone else had this problem? Anyone found a solution?
