Also share your system service tag so that I can check the Bluetooth card shipped with your system to provide you the correct Bluetooth driver
You may find the service tag
**on the bottom of the laptop on white sticker
**it’s a seven digit alphanumeric code which ends with BS or number 1.
If you experience any difficulties, please feel free to contact me directly by sending a reply to this blog or marking me an email.
