By following these steps, you can control how your computer uses power when it’s not in use. If you want to conserve power, you can reduce the brightness of the display or set it to turn off after some amount of time. If you want your computer to run faster, you can increase the brightness level and disable power-saving features like Hibernate and Sleep mode. Additionally, you can also set up notifications that will inform you when the power settings have changed.
