Click on the Windows 10 icon in the taskbar, located in the bottom left-hand corner of the screen. Then click on “Settings”, which can be found directly above the Windows 10 icon.
Next, click on “System.”
Then select “Power & Sleep.”
On notebook computers, be sure to change the settings for “When plugged in.” EPA recommends setting monitors to turn off after 5 to 20 minutes of inactivity, and computers to enter sleep after 15 to 60 minutes of inactivity. The lower the setting, the more energy you save.
