 +  - Press the power button while these keys are held, and then release all keys at once
 +  - (Note: the following is true on my Mac but may not be the same for all Macs:) The LED on the power cable was orange before you started this. After the SMC is reset, you will know that it worked because the LED will flash green, and then change back to orange

 +  - Locate the following keys on the keyboard: Command (⌘), Option, P, and R
