This laptop supports Microsoft Windows 7 and Windows 8.1 only on 64-bit architecture. You can find the drivers on the official website of the developer. There is a possibility to download all the necessary drivers, not only the Bluetooth one. After the operating system has been selected, wait for the page to load, then expand the Driver - Network category using the "+" sign and download the Qualcomm Atheros QCA9000 Series Bluetooth 4.0+HS Driver package. After the drivers has been downloaded, right click it and select Run as Administrator. When prompted, activate the Bluetooth function with the WiFi combination. This will trigger Windows to automatically install the necessary drivers.
After the installation finished, you can access Bluetooth from the system tray. To detect devices, go to Settings and check to make the device Detectable. Once you activate the options, you can pair it with other devices.
