I have a Pavilion DV7T-7000 a 3 years old i was wondering if this laptop has a Hardware/Software Bluetooth? If not can i buy a Bluetooh hardware? Having this chipset https://s3.amazonaws.com/uploads.hipchat.com/31780/239238/4WIQUliVCqytZK6/hpchipset.png that's a kind a weird because my old very old laptop had Bluetooth but this HP does not??? Thanks a lot.
