CAUTION: To prevent an unresponsive system, replace the wireless module only with a wireless module authorized for use in the computer by the governmental agency that regulates wireless devices in your country or region. If you replace the module and then receive a warning message, remove the module to restore device functionality, and then contact technical support.

Before removing the WWAN or GPS module, follow these steps:

1.Shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the computer on, and then shut it down through the operating system.

2.Disconnect all external devices connected to the computer.

3.Disconnect the power from the computer by first unplugging the power cord from the AC outlet and then unplugging the AC adapter from the computer.

4.Remove the following components:

a.Battery (see Battery on page 40).

b.Service access cover (see Service access cover on page 43).

Remove the WWAN or GPS module:

1.Disconnect the antenna cable or cables (1) from the WWAN or GPS module.

NOTE: The antenna cable with the red label is connected to the WWAN module “Main” terminal. The antenna cable with the blue label is connected to the WWAN or GPS module “Aux” terminal.

NOTE: The GPS module does not use the Main cable, therefore the Main cable is not connected. When you work with the GPS module, it is important to keep the plastic tubing that covers the Main cable in place.

2.Remove the 2 Phillips 2.0×3.0 screws (2) that secure the WWAN or GPS module to the system board. (The module tilts up.)
