If you have the blue light on on your Notebook, and BIOS says the Bluetooth card is installed then you have Bluetooth.
your cell phone doesn't find the laptop, the Laptop has to find the cell phone. And really then all it's good for is using your cell phone as a dialup modem. And in some cases your cell provider will lock even that out (they want you to pay for their datacard and/or data service). I have a Moto RAZR V3c through Alltel and while Alltel doesn't lock down the phone like Verizon, Alltel does prevent you from using the phone as a modem. Basically all I used the Bluetooth link for is to send ringers to my phone and send pictures I take with the camera to my Laptop.
To transfer stuff to your phone (Mind you, this is assuming your carrier or your phone supports uploading files via Bluetooth):
1. right click the bluetooth icon in the system tray
2. select wireless file transfer
3. on the PHONE you'll need to engage discovery or "find me" mode (You would also do this to link the phone to your Laptop as a modem). This is where the phone advertises its presence for a minute or so.
4. While the phone is broadcasting itself click the search button in the file transfer window
5. Once the phone has been found you can add files using the "Add.." button in the top half of the window.
6. Once you've added all your files click send
Now you only need to do that once. Once you've sent files to the phone for the first time you can right click any single file or folder you want to send to your phone in Explorer and choose "to Bluetooth" then select your phone as the recipient. All you do then is confirm the transfer on the phone.
Like I said though, this is all dependent upon what your phone and cell carrier will allow. Some carriers *cough* NEXTEL *cough* (who I have my business cell through) make it all but impossible to put user created ringtones on their phones.
