Hi Atef engineer,
Please share the operating system and elaborate the issue. Are you not able to connect to Bluetooth at all or it loses connection or any other issue? Please check in ‘Device Manager’ if Bluetooth is getting detected. Paste a screenshot of ‘Device Manager’ with ‘Network Adapters’ expended. You may follow the steps below:
- Press ‘Windows’ key + R on ‘Desktop’ screen.
- Type ‘devmgmt.msc’ in run box and press ‘Enter’.
- Click > sign next to ‘Network adapters’.
You may update the system BIOS. Please refer to the link: http://dell.to/11gI5U6.
Keep me posted with the information. I will be glad to assist you.
