Myriam a.k.a. [tnkgrl] decided that the the Averatec 1050 laptop was sorely in need of some Bluetooth and was tired of losing a port to a USB dongle. The AV1050 reports 3 usb ports in the device manager, but only features two external ports. She disassembled the laptop and went looking for the third port. The end result is 2 fully functioning USB ports and internal Bluetooth. There's enough detail in the post you should be able to pull this off with other laptops as well.
