The Razer Orochi 2015 uses Bluetooth Smart (BT 4.0 / BLE) technology. Ensure your laptop supports Bluetooth Smart (BT 4.0 / BLE) technology as the Orochi 2015 will not be able to pair with older versions of Bluetooth. If your laptop does have Bluetooth Smart (BT 4.0 / BLE) technology and you have downgraded to Windows 7, your laptop will not have the necessary driver to support the Razer Orochi 2015. Bluetooth Smart dongles are available for purchase from various manufactures and will enable your laptop to use the Razer Orochi.
