The Bluetooth antenna wire, Bluetooth module or system board may be the reason of a
Bluetooth fault. Any of these components may be damaged. To determine if the computer’s
Bluetooth is functioning properly, perform the following procedures. Figure 2-15 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
Procedures, and perform the following checks.
Check 1 Make sure that the Bluetooth antenna is firmly connected to the Bluetooth module
(refer to Chapter 4 for instructions) and that the Bluetooth FFC is securely slotted
into the system board. If the problem persists, go to Check 2.
Check 2 Check that the Bluetooth communication switch is turned to “On”, make sure that
the communication LED on the left panel is lit. If the LED is lit but the Bluetooth
function is still faulty, the antenna module may be damaged. Replace with a new
antenna following the steps in Chapter 4, Replacement Procedures. If the problem
persists, or if the Bluetooth communication LED is not lit when the Bluetooth
communication switch is turned to “On”, go to Check 3.
