   • Cause: Faulty Bluetooth module, broken antenna traces, or software issues.
   • Solution: Replace the Bluetooth module, repair antenna traces, and update or reinstall system software.

10. Dead CMOS Battery:

    • Symptom: Incorrect system time, loss of settings, or boot issues.
    • Cause: Dead or faulty CMOS battery on the motherboard.
    • Solution: Replace the CMOS battery to restore proper functionality.

11. Faulty RAM:

    • Symptom: System crashes, freezes, or displays error messages.
    • Cause: Defective RAM chips or poor solder joints.
    • Solution: Replace the defective RAM chips or reflow the solder joints.

12. Ethernet Port Issues:

    • Symptom: Inability to connect to the internet via a wired connection.
    • Cause: Damaged Ethernet port or faulty Ethernet controller IC.
    • Solution: Replace the Ethernet port and the controller IC if necessary.

13. Disk Drive Malfunctions:

    • Symptom: Discs not recognized, ejected randomly, or not loading.
    • Cause: Faulty disk drive controller on the motherboard.
    • Solution: Replace the disk drive controller IC and ensure proper connections.

14. No Video Output:

    • Symptom: The console powers on, but no video is displayed.
