So, I understand that your system did not come with Bluetooth* adapter preinstalled. If the Bluetooth* portion of the adapter is not detected in device manager it probably means that is also not detected by the system BIOS. You may indeed try updating your BIOS; however, we may need to consider few things:
- Just like any other device, not all wireless adapters are physically and electrically compatible with all systems.
- The system BIOS could be designed to accept certain wireless adapter models only.
- The installation of these adapters is subject to country-specific regulatory approvals which include the system, wireless adapter and antennas.
Therefore, it is highly encouraged to contact your system manufacturer in order to obtain a list of validated wireless adapter models that are compatible with your system and the proper means to accomplish this hardware integration.
