Closing laptop lid causes game lagging on external monitor

2019-05-09, 4:21 AM

I have noticed that whenever I close the lid of my laptop the game running on my external monitor starts lagging but when I open the lid, it starts acting normal again! I have selected the "do nothing" options as well for lid closing. 

 

How can I fix this?

what are the temps like when you game on the laptop with the lid closed, and do you mean fps drop or the inputs take time to display the action you have just input?

I have attached screenshots from MSI afterburner, one with lid closed and other with lid open. 

I see GPU and Memory clocks drop considerably when lid is closed, is this causing the issue? 

 

It's the input which takes time to display the action.

in Control Panel\Hardware and Sound\Power Options try setting the power to performance, and see if that helps

 

Edit:

 

you could try the newer drivers and see if that helps (after you try power performance first) driver verson is 430.64

All are set to "Do nothing". I already had changed them long time ago so that isn't the issue.

Yes the option is already on "High performance" under Power options. 

Do you mean Nvidia driver?

They are upto date. 

 

Seems it's a design flaw by Lenovo as I have digged up internet for some solutions and came across one of the posts. Due to the vent grills being right under the lid, so once the lid is closed the system has no where to throw out the hot air that's why the GPU cannot cool it down and thus the reason. I don't know if this is really the cause of it or not but it sure seems appropriate reason.
