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 WLAN module, follow these steps:

Turn off 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.

Disconnect all external devices from the computer.
