Blue Tooth is hardware and this you have to install along with the software to use the Blue Tooth devise.
It is optional so check when you order the lap top and add it if it is not installed.
Go to Asus and look up the model and its features, installed devises/hardware and select to add Blue Tooth when you order the lap top. Asus eStore: http://us.estore.asus.com/
You can also purchase a external USB or card type Blue Tooth adapter to add it to a lap top that does not have it installed from factory.
