The settings you choose will be dependent upon how you use your computer. The schemes in the pull down menu allow you to select one, general option that will adjust all the power settings automatically. This can be useful, but for most people, it’s better to choose settings individually so you have the most control over making the options work for you. From this tab you can change monitor power settings, hard disks, and system standby.
If you set your monitor to turn off after 1 minute, but you do a lot of reading online, the monitor may shut off when you don’t want it to. Monitors can be set to turn off after 1 minute all the way to 5 hours. While choosing any of those settings is better than just leaving it on, 5 hours is pretty unnecessary. Set your monitor to turn off after 5 minutes, then adjust it to your liking. The lower you set it, the better. When your monitor is off it’s consuming less energy. By setting it to turn off, you won’t have to remember to hit the power button. Alternatively, laptop displays consume less power, but you will still reap benefits from adjusting your power settings.
Your hard drive is one of the worst power consumers. The options for when your hard drive turns off are the same as with the monitor setting. This setting stops your hard drive when you’re not using your computer. If you often walk away from your computer only to come back five minutes later, then give yourself a bit of leeway with this setting.
