How do I connect a Bluetooth Wacom Drawing Tablet to my laptop?

I just got a graphire WACOM drawing tablet and Im not sure I have Bluetooth on my computer. There's a bluetooth symbol above my keyboard (next to my power button) but I've never seen it lit. I followed the instructions and the computer isn't recognizing the tablet.

I also did a search on my computer for anything containing "bluetooth" in it, and nothing came up.

I think I might have to buy a bluetooth adapter, but Im clueless to which one. Or if I can just download something? I have an Inspiron E1505 with Windows XP, Windows Vista compatible.

any help would be incredibly appreciated.

I have the same tablet, you dont need the bluetooth, just install the CD that comes w/ the tablet.
