But i will recommend you one simple solution that is that you have to update the driver of your laptop Bluetooth and also install the latest driver of your mouse Bluetooth. This is IEEE standard and the window recognize it automatically but still the dell Bluetooth have this problem. Hope this will solve you problem.
If your Bluetooth icon is grayed out, your Bluetooth card may be turned off. Try using the FN + F2 or just F2 or FN + F11 or FN + F6 or look for the wireless switch on the computer and turn it on.
Make sure you have new batteries installed on your Bluetooth mouse and make sure you have lights on with it. Most Bluetooth mice have their Bluetooth lights blink when they are discoverable, try and see if this is true with your mouse.
Also make sure you have the latest Bluetooth drivers for your Bluetooth card. Go to support.dell.com to get these and have your service tag ready so that after you enter it the website will give you the drivers specifically for your laptop.
If the Bluetooth icon is grayed out at the bottom right of your screen, make sure that the Bluetooth radio is turned on. Some Dell Inspiron models have a wireless switch that can be configured to control the wireless card, mobile broadband card and the Bluetooth card. Make sure the switch is on so that the Bluetooth radio gets turned on.
After that, the computer should be able to detect the Bluetooth devices as soon as you make it search for devices in range. Once it sees them, just have them paired with the computer and as soon as the Bluetooth profiles are saved on the computer, they will be able to work and connect automatically when the computer is turned on.
