Yoga 260 could not wake up from sleeping mode when it is connected to Onelink plus dock.
Yoga 260 is connected to a Onelink plus dock and one external montior is connected to the dock using DP cable. Yoga 260 goese to sleeping mode when user closes its lid, but it could not wake up when user opens its lid - there is no display on both screen. However, if we disconnect the laptop from the dock right away and open the lid, there is display on the laptop screen, further, if we connect the laptop back to the dock, both screen will have display.
We have updated drivers on the laptop and changed Onelink plus dock. But the problem is still there.
Any one had the same?

the problem is caused by the latest Display driver ( intel HD graphics 520, ver 22.214.171.12485).
I reinstalled OS with display driver ver 126.96.36.19950 on the laptop and did not have the problem. The problem comes back once display driver is updated.
