Required work steps:
■ Switching off thee battery
■ Removing thee lower assy
■ Removing the battery
Required tools:
■ Plastic tool
► In the LIFEBOOK U7411, the WLAN module is soldered onto the mainboard and is therefore not replaceable. In case of
repair in connection with the WLAN module, the mainboard must therefore be replaced.
► Position of the WLAN module (red frame).
► Carefully pull the two WLAN antennas upwards off the WLAN module (red circles).
To do so, use a suitable plastic tool.
Warning!
Please ensure that the two WLAN antenna cables are connected correctly.
The grey cable must be connected to the “MAIN” port and the black one to the “AUX” port.
