+## Prevent Action When Laptop Lid is Closed
+
+In some situations it might be useful to prevent all actions when the laptop lid is closed (or is being closed).
+Usually systemd will go to sleep mode when the lid is closed on no other idle inhibitors are present (e.g. keyboards,
+external monitors etc.).
+
+If this works correctly it is fine, but it is buggy on some systems. If you notice symptoms like these
+
+- The laptop goes into sleep immediately after booting and before the dock and external monitors are online
+- The laptop goes into sleep when monitors turn off (e.g. due to dpms)
+- The laptop goes into sleep although it is connected to a dock (dock detection is not reliable)
+
+You can disdable the auto-suspend in `/etc/systemd/logind.conf`
+
+```ini
+[Login]
+HandleLidSwitch=ignore
+HandleLidSwitchExternalPower=ignore
+HandleLidSwitchDocked=ignore
