From left to right on the front edge of the lower portion of the computer (Not the display) The wireless switch button is the third switch from the right. Or just to the left of the power indicator light. These buttons are located in between the speakers. The buttons and lights are described below. a link to the download the complete user manual to PDF is located below.
