2.16 Bluetooth Troubleshooting

2 Troubleshooting Procedures

Procedure 3 Antenna Check

Check 1 Use an antenna test cable to check the antennas' connection. Follow the steps below:

1.Disassemble the computer and disconnect the Bluetooth antenna cable connected to the Bluetooth module. Refer to Chapter 4, Replacement Procedures, for detailed steps of disassembling.

2.Connect the end of the antenna test cable to the multimeter.

3.Connect the Bluetooth antenna cable to the antenna test cable. One clip is connected to the end of the Bluetooth antenna cable. The other is connected to the opposite side of the Bluetooth antenna cable.

4.Determine the resistance. The cable passes the test when the resistance is less than 5Ω. If it is more than 5Ω, the Bluetooth antenna cable fails the test.

Note: 1. The resistances determined with the steps above may not be stable according to the length of the antenna. The impedance of the antenna itself is about 0.5 to 0.8 ohm.

2.The above steps cannot accurately determine the impedance of the antenna. Use a LC meter for a precise measure of impedance.

If the Bluetooth antenna cable pass the test, connect it to the Bluetooth module and cover the slot, then perform Procedure 1.

If the Bluetooth antenna cable does not pass the test, go to Procedure 4.

Procedure 4 Replacement Check

Check 1 The Bluetooth module may be defective or damaged. Replace the Bluetooth module with a new one following the steps in Chapter 4, Replacement Procedures. If the Bluetooth is still not functioning properly, perform Check 2.

Check 2 The system board may be defective or damaged. Replace the system board with a new one following the steps in Chapter 4, Replacement Procedures.
