Windows 11 introduced a shift toward smartphone-like behavior. This distinction is crucial:
Even if your device supports Modern Standby, Windows 11 is conservative about when it will run updates while "sleeping" to prevent you from picking up a hot laptop with a dead battery.
Search for "Security and Maintenance" in the Start menu, expand Maintenance , and ensure the option to let the computer wake for scheduled maintenance is checked.
: If an update requires a reboot, Windows may restart your computer while it is technically "asleep." This can lead to the loss of unsaved work in open applications that do not have auto-save features.
