lid close settings

Lid close settings determine what a Windows laptop does when you shut the lid, and getting them wrong causes real problems: a machine that ignores the lid, wakes seconds later, or runs hot inside a bag. This tag covers those scenarios, including the distinction between the lid-close action itself, devices or timers that wake the PC after sleep, and drivers or firmware mishandling low-power states. Because many modern laptops use Modern Standby instead of the older S3 sleep state, a dark screen alone does not prove the system reached low power. Related discussion points to Power Options and powercfg for checking available sleep states.
