    Bought a T440s yesterday. Got it all set up, everything working fine, including bluetooth. Paired a BT mouse, rebooted, now bluetooth is totally absent from the system. Uninstalled all BT related drivers. Tried windows update. Tried Lenovo update. Looked in device manager, it's not there. Installed Intel update, ran it, installed BT drivers. Rebooted. Nothing. Installed Realtek BT drivers from Lenovo. Not there. I get this error (attached).

    The system does have it, it's just gone somehow.

    What in the world?

    Well, I uninstalled a bunch of updates that I installed this morning, rebooted. Ran Lenovo update, it picked up a WLAN update, installed and it started working again. Whew.

    Then, I rebooted just now after using it for hours (bluetooth mouse). Now it's not working again and bluetooth is nowhere to be found.

    This is getting aggravating. There is a rogue update that's killing BT and I am getting tired of tracking it down.
