Common repair scenario: Lenovo LOQ 15 Bluetooth option has disappeared completely.

Bluetooth usually shares hardware with the Wi-Fi module but has separate USB/control paths and software services, so Wi-Fi can work while Bluetooth fails.

Symptoms to confirm

  • The reported symptom is repeatable and not caused by an attached peripheral or temporary setting.
  • Note whether the fault changes on battery power, charger power, external display/network, or after a cold restart where relevant.
  • Record any LED blink code, beep, error text, temperature, sound or smell before opening the device.

Likely areas

Bluetooth disabled or service stopped, driver corruption, radio interference or pairing cache issue or combo-card USB/control path fault are common areas to check; the actual failed part must still be confirmed on the device.

Safe first checks

  1. Confirm Bluetooth is enabled in firmware/OS and airplane mode is off.
  2. Remove the old pairing and test with a second known-good Bluetooth device.
  3. Check Device Manager/system information for the Bluetooth adapter and error codes.

Question: What diagnostic order and repair path should be followed for this Lenovo LOQ 15 fault without replacing parts by guesswork?

Accepted TCS AI solution for Lenovo LOQ 15: diagnose the fault in stages and replace a part only after the failed stage is proven.

Diagnostic order

  1. Confirm Bluetooth is enabled in firmware/OS and airplane mode is off.
  2. Remove the old pairing and test with a second known-good Bluetooth device.
  3. Check Device Manager/system information for the Bluetooth adapter and error codes.
  4. Install the OEM wireless/Bluetooth driver pair for the exact module.
  5. If Wi-Fi works but Bluetooth is absent at hardware level, investigate the module USB/control path.

Repair path

  1. Restart/repair the Bluetooth service and clear corrupted pairings.
  2. Install the correct driver/firmware package.
  3. Reseat or replace the combo wireless module when hardware detection is proven faulty.
  4. Diagnose the board-side USB/control path when multiple known-good modules show the same failure.

Verification after repair

Repeat the original symptom test, complete at least one cold boot/restart cycle, and check the related function under normal load. Confirm there are no new warnings, abnormal heat, intermittent connections or charging/display/network errors before closing the job.

Safety: Disconnect battery before removing an internal wireless card and reconnect antenna leads carefully to avoid connector damage.

This is a TCS AI knowledge-base answer based on common repair patterns. Exact diagnosis can differ by board revision and component configuration.
