Windows 10: Laptop primary screen does not turn on after sleep. When plugging in an external display,...

Hi all,


I'm running a MSI GP73 laptop with Windows 10. It has the following periodic problem:

When waking up from sleep, either from being left for a while or by closing the lid, it sometimes wakes up with a black or dead screen. It has definitely woken up but the screen stays black. The only way to get it working again is by a hard reboot, sometimes 3 or 4 reboots are needed. During these reboots, the screen shows the MSI log and then goes black again, suggesting that this is not a hardware related problem.

If you connect an external monitor, the external monitor acts as the primary screen. If you then go into device manager, only the external monitor is listed Generic PnP monitor. It does not pick up the laptop's own screen and there are no unknown devices listed.

I have tried changing all the power and sleep setting.

I have updated the screen's drivers when it is working again.

I have tried to identify a loose connection, but have not found anything. At the moment the laptop acts more as a PC, I do not move it around at all and I still have this problem.


The problem is sporadic, about once or twice a week or sometimes only once a month, so knowing what causes it is difficult. As is knowing when it is fixed...


Any Advice?


Kind regards

How to disable a laptop screen?

Closing it got rid of the laptop's display from being shown in the "Screen Resolution" list, so now it's just the two externals...but it still is saying Unable to Save Display Settings.

 

Laptop display does not detect itself

Hi,

I only have 1 computer (the laptop) and 1 external monitor. The laptop cannot detect its own screen.

So when I follow your steps, this is what happens:

• Go to Settings. (Done)
• Click on System. (Done)
• Under System, choose Display. (Done)
• Under Multiple displays, click on Duplicate these displays and apply. (Done)
• But then I undock my laptop and redock. Re-login, etc.
• Only the external display turns on. The laptop does not turn on its own display. In order to get the laptop display to wake up, I need to follow steps 1-4 again. The settign "Duplicate these displays" does not seem to be retained.
