What is sleep mode?

Sleep Mode is a power-saving state available on all laptop and desktop computers designed to help conserve energy by keeping your programs and files open. When activated, Sleep Mode puts your computer in a low-power state, where processes are suspended and system state is stored in RAM. The advantage is that it allows you to immediately resume full power operation (usually within a few seconds) when you return.

How Sleep Mode Works

During sleep mode, your laptop reduces energy consumption by shutting down unnecessary tasks. The CPU reduces its power usage, the hard drive stops spinning, and the display turns off, but the RAM continues to draw a small amount of power to maintain the current state of open applications and documents.

Differences from hibernate mode

While sleep mode keeps your session in RAM and uses a small amount of power, hibernate mode saves the session to the hard drive and powers down completely, eliminating power consumption. Hibernate mode is typically used for long periods of inactivity, while Sleep mode is ideal for short interruptions.
