Windows 10 normally puts your laptop in low power sleep mode when you close the lid. This can be a problem when you connect your laptop to an external monitor. Use the Control Panel, not the Windows 10 Settings application, to change this behavior.
If you do that, be careful! If you close the lid of your notebook and throw it in your bag while it is still lit, you may experience serious problems due to poor blood circulation or blocked air vents. Your laptop will continue to run, wasting its battery and may even overheat your bag. You will need to manually put your notebook to sleep, hibernate, or shut down by using the power buttons or Start menu options instead of just closing the lid.
To change the default behavior of Windows 10 when you close the lid, right-click the battery icon in the system tray, and then click "Options". ;food".
If you do not see the battery icon, click "Show hidden icons", then right-click on the battery icon or go to Control Panel> Hardware and Sound> Sound Options. 'food.
Then click on "Choose what the lid closes" in the left pane.
In the "When I close the lid" drop-down menu, select "Do nothing".
There are two separate options here: On Battery and Plugged. You can choose different options for each. For example, you might want to leave your laptop on when you close the lid while it's plugged in, but go to sleep when it's on battery power.
The settings you choose will be associated with your Windows Power Plan.
Warning: Keep in mind that if you set the On battery setting to "Do nothing," always make sure your laptop is turned off or in Standby or Hibernate mode when you place it in your bag to avoid overheated.
Once you've made the changes, click "Save Changes" and close Control Panel.
You should now be able to close the lid of your laptop without it going into sleep mode. If you want to restore one of the default settings, go back to Control Panel> Hardware and Sound> Power Options, and then turn it back on.
