AMD power saver If you have an AMD graphics card, there is one more step you can try. Go to the Start Menu and type "regedit". Open regedit and click the Edit button at the top of the screen, then click on Find. Type "EnableULPS" and click "Find Next". EnableULPS will be highlighted in the list of registry options.
