Bluetooth is functioning properly, perform the following procedures. Figure 2-16 outlines the
process. Start with Procedure 1 and continue with the other procedures as instructed.
Procedure 1: Diagnostic test
Procedure 2: Connector and replacement check
Procedure 1 Diagnostic test
Run the Diagnostic Program, which will automatically execute the Bluetooth test. Refer to
Chapter 3, Tests and Diagnostics for more information on the program.
If an error is located, go to Procedure 2. If an error is not located, the Bluetooth system is
functioning properly.
Procedure 2 Connector and replacement check
The Bluetooth, antenna module or system board may be disconnected or damaged.
Disassemble the computer following the steps described in Chapter 4, Replacement

go to Check 3.
