USE LESS POWER AND CUT YOUR BILLS

摘要

Your screen, which relies on a backlight, is one of the most energy-intensive components in your whole set-up, so it's worth putting it to sleep when you're not at your computer. Press Windows key+I to open Settings then, in Windows 11, click System followed by 'Battery power'. Now click 'Sleep and screen' to reveal the settings you need to tweak. If you're using a laptop, you'll see separate settings for battery and mains power. If you're using a desktop PC without an internal battery, the battery settings won't be shown. In Windows 10, open Settings and click System followed by 'Power sleep', then use the two dropdown menus below Screen to specify when the display should switch off when on battery power (1 in our screenshot above) or when plugged in 2, and the menus under Sleep (3 and 4) to specify how long it should wait before powering down if not being used. The shorter the time you choose, the less energy you'll use overall.
