Hi,

Welcome to the Community.

Please provide the System Model.I will check and see the System Specification.
However,generally FN+F2 key is to On the Bluetooth for the Dell Laptops.I hope it helps.

Thanks,

creator4u,

When you installed Windows 7 (32-bit or 64-bit) did you install the desktop/notebook utility and the chipset drivers first? If not the rest of the drivers will fail to install. How to Download and Install Drivers in the Correct Order If you cannot find Windows 7 drivers, then try using the Vista (or XP) 32-bit drivers, for Windows 7 32-bit of the Vista (or XP) 64-bit drivers for Windows 7 64-bit and install the drivers in the Compatibility mode.

hi silangchi S

        thanks for ur reply!

Hi creator4u,

The system specifications and the OS compatible for your system are-

Microsoft Windows® 7 Home Basic 64bit
Microsoft Windows® 7 Home Premium 64bit
Microsoft Windows® 7 Professional 64bit
Ubuntu Linux®

I agree with PudgyOne, that you may need to follow the instructions to install the drivers in the Correct Order.
Follow the link below-  http://dell.to/KpEEEq

And below is the screenshot that you can follow to enable and disable the Bluetooth/Wireless device in your laptop N5110.





I hope this will help you .

Thanks,

well Silangchi i installed win7Ultimate is that the problem of compatibulity You say....?

and i also followed the instructions specified by  PudgyOne and screenshot you have specified but it only activates WLAN but not bluetooth.

creator4u,

If you can run this tool, I can see if the adpater is showing and it may also tell us something.

Download the System Information Tool If using Vista/Windows 7, the tool needs extracted. Once extracted, right click on sysinfo and run as administrator.

If using XP, double click on the tool, then double click on sysinfo.

Allow this past your virus program and post the information back here.

If you cannot get the tool to run, try an ipconfig /all log.
