By default, when the lid is closed, the notebook will go to sleep or stand by, so you can turn it off by setting the computer options. Find the battery icon in the taskbar, right-click, select more battery options, turn on the power option of the notebook, find the "select the lid closing function" on the left, and enter the settings. In the system settings of the lid function that appears, the operation of "When the lid is closed" defaults to "Sleep state". Click the drop-down menu to modify it, and click "Don't take any action" to set the computer sleep time again, as shown in the figure below, and choose not to stand by or change it for a longer time.
