I updated BIOS version to 1.14, based on http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t450 . Then I try to connect BT devices. I chose 2 devices for test, a BT headset (LG HBM 230) and BT mouse (Blutooth Laser Travel Mouse). After the 2 devices connected with system successfully, waiting about 2 minutes. BT headset tried to re-connect system always; BT mouse disconnect with system. But they are show 'Connection ON' in BT indicator.
