1) Right-click on the “desktop” anywhere there is no icon. (The desktop is the main screen where you see the Recycle Bin, My Computer, My Documents, etc. icons.)

2) Click on Properties.

3) Click on the Screen Saver tab.

4) Click on the Power… button.

5) Click on the Down Arrow next to whatever is in the Power scheme box, then click on Always On.

6) You should then see the settings under Plugged in change for Turn off monitor, Turn off hard disk, System standby [Sleep] mode [and Hibernation mode]. Be sure that the settings for all of these say “Never.”

Note: You can change Turn off monitor to After 20 mins if you want to turn off your monitor to save electricity. The monitor will turn on again automatically when you move the mouse or press any key. This feature usually works without any problems.

7) Click on the Hibernate tab, then click to remove the check mark next toþ Enable hibernation if there is one.

8) Click on OK.

9) Click on OK.

10) Close all open programs, then restart the computer for the new settings to take effect.
