Before removing the WLAN 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 battery (see
Battery on page 38).
5. Remove the bottom door (see
Bottom door on page 39).
Remove the WLAN module:
1. Position the computer right-side up with the battery bay toward you.
2. Disconnect the WLAN antenna cables (1) from the terminals on the WLAN module.
