To check if your Dell Latitude E6440 laptop has Bluetooth built-in, you can follow these steps:

1. Click on the Windows Start button and type "Device Manager" in the search bar.
2. Click on the "Device Manager" app that appears in the search results.
3. In the Device Manager window, click on the arrow next to "Bluetooth" to expand the category.
