I use a Surface Dock to connect my Surface Laptop 3 (15"; i7) to an external monitor, keyboard, and mouse. I have an upright aluminum stand that holds my laptop in the closed position. I used this setup before with my Surface Pro 4 and it worked great. With the laptop, however, the Bluetooth is incredibly weak when the lid is closed. I can be sitting 2 ft away and the audio will be choppy. If I open the lid, I can walk into another room and still hear the audio clearly. Has anyone else experienced this? Is it normal that the laptop lid can shield the antenna to this degree or is it possible that I have a faulty antenna?
