This is a state when your PC uses very little power. Whatever is running on your PC at the time, such as websites, applications and open documents, is saved in the PC’s short-term memory, RAM (Random Access Memory).

You can choose after how long your laptop should go into sleep mode from the power and sleep settings on your PC.

In sleep mode, only your laptop’s RAM consumes power while the processor, hard disk, and other components are turned off to save battery. Plus, you don’t have to worry about losing your work because Windows or macOS automatically saves all your work and shuts down the PC when the battery gets too low.

To access sleep mode, simply press the power button on your laptop, or close your laptop lid.
