Use the following information when connecting your computer.
•  Look for the small connector icons on the back of your computer. Match the

connectors to the icons.

•  If your computer cables and connector panel have color-coded connectors,

match the color of the cable end with the color of the connector.

  Note: Your computer may not have all of the connectors described in this 

section.

Check the position of the voltage-selection switch on 

the rear of the computer. Use a ballpoint pen to slide
