I got a new laptop, an Acer Aspire 7740G that seemed to work fine at first sight. It was the last one left in the store so it had been unpacked and used as a viewing model, so when I got it everything was setup already. But the Bluetooth doesn't work. There is a BT button on the keyboard but when I press it it says "no device" and nothing more happens. There is no setup manual in the computer and I didn't get a CD or manual booklet since everything was set up when I got the computer. If they disabled the Bluetooth in the store to prevent people from sending thing to the computerr, how do I enable it again? The reason I bought this computer is because it's supposed to have BT
