Fresh install 14.04.2 on this machine, connect BT devices (headset, BT mouse or mobile phone). They are all working normally. Installed package plainbox-provider-certification-client 0.17 and plainbox-provider- checkbox 0.21 and try to reproduce the issue. It is also can not reproduce any more.
I guess it could fixed by update BISO && re-install 14.04.2. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1454938 Title: [Lenovo T450] BT devices connected successfully 1 minute later, it will disconnect automatically.
