Windows 10: Why does my external monitor stop working when I close my lid?

I have an HP laptop running Windows 10. It is connected via USB C to an official HP docking station. I have 3 external monitors attached to the docking station via a combination of HDMI and DisplayPort. Everything was working fine until a week ago, when my middle monitor DisplayPort would only work when the laptop lid is open. If I shut the lid, the monitor goes black and then a few moments later it goes to sleep. I have tried to detect the monitor with the lid shut and it wont find it. When the lid is shut, there is a grayed out display, but I can do anything to it. I have rebooted he lapto

Keep external monitors on when laptop lid is closed

Just in case this hasn't been resolved yet, you can get to the laptop lid settings by going to Start Menu and finding "Control Panel." When there, choose Hardware and Sound > Power Options. When on the "Power Options" screen, the list of options on the left should contain "Choose what closing the lid does." Choose that option and you should see settings for "When I close the lid" when "On battery" and when "Plugged in." You could choose to set both to "Do nothing." I usually set the "Plugged in" option to "Do nothing" when connected to external monitors.

NOTE: There is a quick way to get here from the Settings app too. There should be a "Find a setting" search box on the left. Type "lid" in there and hit Enter. A suggestion should come up that says "Change what closing the lid does." If you select that suggestion, it will take you to the same Control Panel location I mentioned above.

 

DUal monitor / close lid / desktop moves

Hello

Notebook with external monitor.
Active Desktop is on embedded monitor.
Close lid, desktop jumpes to external monitor. How to stop that bad behavior?

Power Options: When I close the lid: Do Nothing.
That's a blatant lie. It does something. I moves the desktop to the external monitor, which is not helpful.

 

Windows 10 sleeps when using external monitor and closing the laptop lid.

Hey Likitha

Thanks for your response.

Before we assist further, I would like to ask you a few questions:

• Have you set Sleep function to activate on closing the laptop lid?
• Did you check if the laptop goes to sleep when not connected to external monitor and lid closed?

To respond to your questions

(1) I have set the sleep function to operate on laptop lid close only when the laptop is on battery power. When it is plugged in I have set it to do not sleep ever.

(2) I have tested that it does *not* go to sleep when I the laptop is plugged in and I close the laptop lid

Further information:

(1) When I first turned the laptop on I attached it to the monitor and closed the lid. It then ran successfully for approximately an hour before hibernating.

(2) I then restarted the system, external monitor plugged in, lid closed and it went to hibernate after approximately 2 minutes.
