How to Change Power Options On a Computer

by Contributor

You can change the way your computer behaves when it comes to power management. You are not required to keep the factory default settings. This is especially true when your computer hibernates suddenly or will not shut down when you depress the power button. You may also be surprised to know that power settings for a notebook computer and a desktop computer are not identical. Here you will learn some ways to easily tweak and change power options on a computer.

Click on the Windows Start menu and go to Control Panel.

Click the "Power Options" choice located inside Windows Control Panel. The choices are listed in alphabetical order. A photo example of this button is located within this article.

Click on the first drop down box, which displays "portable" or "desktop" types of power scheme choices. Select the one that best suits your computer use even if it is not a desktop or laptop. Doing this will not adversely affect your computer.

Click on the "Turn Off Monitor" options and select your desired time limit from the drop down box. You can feel free to select "never" for this choice and any of the others. One column displays "Running on Batteries" while the other displays "plugged in options." Your selections can be different for each. Make your choices according to your use and preferences of your own computer. A photo example is shown within this article.

Click on "System Standby" and make any changes to the time limits as needed. This is optional. It may be best to select "never" or at least a few hours for this choice.

System Hibernate

Click "System Hibernates" if you wish to have your computer hibernate (or "sleep") after a certain length of time. This again is entirely optional and not required. When you are finished, click "OK" to save all of your choices. This is very important.
