What is sleep mode on a laptop?
Sleep mode is a power-saving state that your laptop enters after a certain period of inactivity. In this state, your laptop essentially saves the current session to RAM and reduces power usage by turning off the display and putting the processor in a low-power state. Sleep mode allows you to quickly resume your work without fully shutting down the system.
While sleep mode can help conserve battery life, it can be inconvenient if you’re in a situation where you want your laptop to remain awake, such as during a presentation, when downloading large files, or while watching a movie. Knowing how to prevent your laptop from entering sleep mode can enhance your user experience in these scenarios.
