Step 1: Check If Bluetooth Is Actually Installed

  1. Press Windows + R, type devmgmt.msc, and press Enter – this opens Device Manager.

  2. Look for Bluetooth in the list.

    • If it's there, expand it and see if anything has a yellow warning icon.

    • If it’s missing, it could mean the driver isn't installed or Bluetooth is disabled in BIOS.


Step 2: Check in Network Adapters

Still in Device Manager:

  1. Scroll down to Network adapters.

  2. Look for any Bluetooth-related devices (e.g., Intel Wireless Bluetooth).

If it's not there either, read on.


Step 3: Enable Bluetooth in BIOS

Sometimes, Bluetooth is disabled at the hardware level.

  1. Reboot your laptop and tap Esc or F10 (depends on your model) to enter BIOS/Setup.

  2. Look for something like Built-in Device Options.

  3. Make sure Bluetooth Device is enabled.

  4. Save and exit.


Step 4: Install Missing Drivers

  1. Go to HP’s official driver site.

  2. Search for HP EliteBook 840 G3.

  3. Download and install the latest Bluetooth driver (usually under Driver-Network).

  4. Reboot after installation.


Step 5: Check Services

  1. Press Windows + R, type services.msc, press Enter.

  2. Look for Bluetooth Support Service.

  3. If it's not running, right-click > Start.

  4. Set it to Automatic by double-clicking it.


✅ Optional: Use HP Support Assistant

HP has a built-in app that can help install missing drivers:

  • Search for HP Support Assistant in Start menu.

  • Open it, check for updates, and install anything related to Bluetooth.
