Windows 11, especially on newer laptops and Surface devices, often uses Modern Standby instead of traditional S3 sleep. In this state, the system is technically still "on" but in an ultra-low-power mode. The CPU can wake briefly for background tasks (like email sync or Windows Update checks) but prioritizes power saving over performance. Here, downloads might continue for a few minutes after the screen turns off, but within 5-15 minutes, the system typically disables network connectivity to save battery.
However, the long answer is far more nuanced. Microsoft has introduced several power-management features (like Modern Standby and Away Mode) that blur the lines.
