When closing the lid of your laptop, your computer suspends in order to save power. You can prevent the computer from suspending when closing the lid by changing the setting for that behavior. Warning
Some laptops can overheat if they are left running with the lid closed, especially if they are in a confined place like a backpack. Therefore, consider if changing the default setting (suspend) is the best option in your case. Procedure 13.10. Configuring the lid switch
1 - Open the /etc/systemd/logind.conf
file for editing.
2 - Find the HandleLidSwitch=suspend
line in the file. If it is quoted out with the # character at the start, unquote it.
If the line is not present in the file, add it.
3 - Replace the default suspend parameter with
For example:
[Login] HandleLidSwitch=lock
4 - Save your changes and close the editor.
5 - Run the following command so that your changes preserve the next restart of the system:
# systemctl restart systemd-logind.service

file, see the logind.conf(5)
