The bluetooth is not a piece of software, it's a piece of hardware , it's a chip
If your laptop has no chip then you'll have to use an external USB one
However if you have the chip then you have to install the driver ie the piece of software that runs that chip
I assume your laptop is Toshiba , some of them comes with no Bluetooth chip and few do
Please check the (BOX) which the laptop came in as it should be written there under the label "specifications"
Al Salam Aleikum
