system is functioning properly, perform the following procedures. Figure 2-12 outlines the
process. Start with Procedure 1 and continue with the other procedures as instructed.
Procedure 1: Wimax connection test
Procedure 2: Connector and replacement check
Procedure 1 Wimax connection check
PLS use windows application. If an error is located, go to Procedure 2. If an error is not

Procedure 2 Connector and replacement check
The Wimax antenna, Wimax unit or system board may be disconnected or damaged.
Disassemble the computer following the steps described in Chapter 4, Replacement
Procedures, and perform the following checks.
Check 1 Make sure that the Wimax antenna is firmly connected to the Wimax module

Procedures. If the problem persists, or if the wireless LAN LED is not light when
the wireless communication switch is turned to “On”, go to Check 3.
