Why does a laptop think longer with the lid closed?

Question

System administration

Hello!
I have such a problem: when you close the lid of the laptop, because there is an external monitor, it starts to "think" slowly. It is not visible in the system itself. But when loading a site (in all browsers EDGE, Chrome, Opera, Mozilla) they are loaded for a very long time. The problem is in the closed lid. The wi-fi signal level remains the same, the speed is the same.
How does everything look? When I open a link, the site starts loading only when the tab is in focus, in the background it does not load, or it takes a very long time to load.
Notebook model Asus Zenbook ux31a. I did not find an answer on the Internet. I agree, maybe I didn't search well. But has anyone else experienced something similar? Once again, when I open the lid back, everything returns to its place and works correctly. I know about the parameters of the system's action when the lid is closed. Everywhere is worth "Do nothing".

Answer 1

Browsers have long been catching the events of minimizing a window, an inactive tab, and closing the lid (turning off the screen) ... in this mode, the entire work of the site is STRONGLY slowed down forcibly or even stopped.

Why does a laptop think longer with the lid closed?

Here is one of two options.

• When the lid is closed, the power saving mode is activated and the processor resets the frequency to a minimum. To be treated by disabling this function - this can be either an OS setting or a manufacturer's proprietary driver setting.
  
• Banal overheating - when the lid is closed, heat is removed worse, the processor goes into throttling.

Take your temperature. Some laptops partially use the keyboard holes for cooling. When the lid is closed, it is respectively harder for them to cool, with all the ensuing consequences.
