Please help..

How do i find out i have a bluetooth device built in my laptop and when i find it how to i switch it on? At the front of my Acer TravelMate 4200 i have a switch that's meant to turn Bluetooth on but this does NOT do the job! I have updated the driver during which period the installation told me the device could not be located. I thought it should be built in! Going through advanced setting and safe mode did not help.

Specs:
TravelMate 4202WLMi
Intel Core Duo T2300E (1.66GHz, 667MHz)
1GB DDR2
120GB HDD
802.11a/b/g wireless LAN
