Hi Herve, 
  
Bluetooth LED light is on when I power on and it stays even when OS loads. When I go to utilities -> Bluetooth it does not recognize that there is Bluetooth on the laptop.  
  
About the wifi, I am not sure whether it is intel based or not. It says Dell PR032 350 Truemobile Bluetooth Adapter Card on dell website when I look up my system spec. PR032 is the part number. 
  
PR032 1 CARD (CIRCUIT)..., WIRELESS..., INTERNAL..., BLUETOOTH..., 350, VSTA 
  
How can I know if it is intel card? Do I need to buy another card or USB wifi adapter?  
  
Thanks for your help 
  
  
Thanks and Regards, 
Srikanth
