Dell Inspiron N5110_ Function keys work directly and bluetooth not working

Hello, 

The reason why F2 directly turns on the wireless instead of Fn+F2 is because the Function Key behavior might have been set to Multimedia. We need to change the settings from Multimedia to Function Key. Please follow the steps mentioned below to change the settings.
-- Click Start.
-- In the search program and files tab type “windows mobility center”.
-- Select “Windows Mobility Center” from the list.
-- Look for the option “function key behavior”.
-- If on multimedia change it to function key.
-- Save it and exit.
-- Restart the computer and check the functionality.



Regarding the issue with Bluetooth, that it gives error as "Windows has stopped this device because it has reported problems. (Code 43)", I would suggest updating the BIOS to latest version. Refer the following link to update the Bios: http://dell.to/UmY8yD

Please try the steps and write back with results, would be glad to assist further.

Thanks a lot. The function key problem is resolved but bluetooth problem still not resolved. i tired updating the BIOS got restarted but still the same problem.

Hi Allan,

Sorry to get back to a little late. I tried the above but still of no use.

Would be really helpful as this is really getting irritating for me even though i don't use the bluetooth but still I just to get this issue resolved.

Thanks

Hello,

Apologies for the late response. In such case, we would have to uninstall and re-install the Bluetooth driver. 
-- Click start.
-- Open Control Panel.
-- Open Device Manager.
-- Choose Network Adapters.
-- Uninstall the Bluetooth driver.
-- Restart the computer.
-- Download and Install the Bluetooth drivers.
-- Choose the Bluetooth adapter from the list under Network Adapters and install it.
Restart the computer and check the functionality.

Please write back to us with results.
