Comment 80 for bug 1275794

The patch doesn't work with a t440 on its docking station. Still 20-50 seconds between eDP<->DP switches in which the cpu seems to burn (fan goes up). Sometimes the external screen comes on shortly but then get black again leaving the system non responsive. One good thing the patch does is to lower the power consumption when the system is idle (no matter if attach to dock od running stand alone) from 18 watts to 10 watts. So I guess there is much more going on here that needs to be fixed.
