On either the right-hand (I believe) or left-hand side, there should be a switch. Flip it to the "on" position to turn the wifi/bluetooth radio on.

Open Control Panel, switch to Classic View, and lok for the Bluetooth icon. You can double-click this and it will show you all the settings for your Bluetooth.
The camera is right atop your monitor screen-- it's very small.
