We’ve all been there: you’ve got a massive game update or a 4K movie downloading, and you’re ready to hit the hay. You close your laptop lid, thinking it’ll be ready by morning. But when you wake up, that progress bar hasn't budged an inch.

Go to (while plugged in). Then you can safely close the lid (if your laptop supports running closed) or just leave it open with screen off.

– most laptops pause downloads when entering traditional sleep mode (Suspend to RAM). However, Modern Standby (S0 low-power idle) on some Windows laptops and Macs may allow background downloads in specific scenarios.

To understand why downloads typically cease in sleep mode, one must first understand what "sleep mode" actually does. Sleep mode is a low-power state designed to preserve battery life and reduce wear on hardware components. When a laptop enters sleep mode, it essentially puts the computer into a suspended animation. The operating system saves the current state of open documents and running applications into the Random Access Memory (RAM). While the RAM remains powered on to keep the data alive, most other hardware components are shut down. The hard drive or Solid State Drive (SSD) stops spinning or accessing data, the network card (Wi-Fi or Ethernet) disables its active connection, and the processor enters a low-power state. Because the network card is disabled and the hard drive is inactive, the laptop cannot communicate with the internet to receive data packets, nor can it write those packets to storage. Consequently, the download is effectively frozen in time, only to resume—if the software supports it—once the computer is awakened.

However, you can configure your laptop to stay active enough to finish downloads even with the lid closed or after you've walked away. Why Sleep Mode Stops Downloads

To ensure your downloads finish overnight or while you're away, you must prevent the system from entering a full "Sleep" state. For Windows 10 & 11
