Going back from hibernation problem

[krzcho]

I got the following problem. I hibernate my laptop in a state where main display panel is turned off and DL monitor is used. After going back from hibernation and now having DL adapter turned off I got blank laptop panel
Any ideas how to solve it?

I will add that DL was initially attached through docking station while woken up without it

Does the DL monitor mirror the laptop display or does it stay black just like your laptop panel after going back from hibernation?

DL is not mirroring laptop as it has larger resolution so to use external panel efficiently I needed to turn laptop panel off to set higher resolution on DL adapter.
As I have written before: after going back from hibernation DL is detached.

Let me repeat all steps:
1. DL attached through docking station, laptop panel turned off using DL manager
2. laptop hibernated
3. docking station with DL adapter detached
4. laptop woken up with its panel turned off

The question is: does Windows allow to have no active monitor? Is it the job of Windows to turn laptop panel on after DL detach or is it DL manager' task?
Nevertheless maybe DL manager can do some check that when DL adapter is gone then panel that was previously turn off by it should now be enabled?

Hi

This might be a problem with the primary graphics driver not enabling the laptop screen. Are you using Intel graphics by any chance?

Yes - it is Intel's integrated one
