Configuring Power Settings to Keep External Monitor Active When Laptop Lid Is Closed

To maintain an external monitor’s display while your laptop lid is closed, adjusting the power settings in your operating system is essential. By default, most laptops enter sleep or hibernate modes upon lid closure, which disables the external monitor. Modifying these settings allows the laptop to stay active and output to the connected display.

For Windows Users:

  • Open Control Panel and navigate to Hardware and Sound > Power Options.
  • Select Choose what closing the lid does from the sidebar.
  • Under the section labeled When I close the lid, set both On battery and Plugged in to Do nothing.
  • Click Save changes to apply the settings.

This configuration prevents the laptop from sleeping or hibernating when the lid is closed, allowing the external monitor to remain active.

For macOS Users:

  • Connect the external monitor, keyboard, and mouse to the MacBook.

  • Close the MacBook lid; the external monitor should become the primary display automatically.
  • If the external monitor does not activate, wake the MacBook using the external keyboard or mouse.

macOS does not provide a direct system setting to disable sleep on lid close, but with the external peripherals and power connected, it supports “clamshell mode” to keep the external display active.

Adjusting Display and Power Options for Linux Systems

Linux distributions vary widely, but most provide control over laptop lid behavior through system settings or configuration files. The method depends on the desktop environment and underlying init system.

Using Desktop Environment Settings (e.g., GNOME, KDE):

  • Access the Power or Power Management section in system settings.
  • Locate the option for Lid close action and set it to Do nothing or Ignore.
  • Save and exit the settings.

Modifying systemd Logind Configuration:

To override lid-close behavior at the system level, edit the /etc/systemd/logind.conf file.

Parameter Recommended Value Description
HandleLidSwitch ignore Prevents the system from suspending or hibernating when the lid is closed.
HandleLidSwitchDocked ignore Specifies behavior when the system is docked; useful for laptops connected to monitors.

After editing, reload the daemon and restart the service with the following commands:

sudo systemctl daemon-reexec
sudo systemctl restart systemd-logind

This ensures the laptop remains active and the external monitor stays on when the lid is closed.
