Notes

When the user has not installed Lenovo Communication Center, directly plug Lenovo Connect or other Bluetooth devices into the WINDOWS XP SP2 system computer, the system will use the driver that comes with WINDOWS by default, so some random application functions cannot be realized. Even if the driver of the device is installed again, the system's default driver support cannot be changed. After deleting the default driver support through the above method, it can be installed again. Lenovo Communication Center or Bluetooth device can come with its own driver.
