Does my notebook have Bluetooth?
Bluetooth is an optional feature on most notebooks. If it won't turn on, or drivers won't install, then check the spec sticker on the box to make sure that your notebook actually comes with bluetooth hardware, as if it doesn't then nothing you do will ever make it work!
This sticker shows that this notebook comes with Bluetooth hardware. If 'BT EDR' is not listed here, then it is not included.
There will also, like for the wireless, be a silver sticker on the base of the unit, which tells you which Bluetooth module is installed. Again, if you see no sticker like this, then there is no Bluetooth inside.
