My Lifebook gets power via its USB-C port when connected to a port replicator.
My problem is that if I plug any other device into the USB-C port (there only is one), the Lifebook is just as likely to take power from the device as it is to supply power to the device. That means when I connect a mobile phone, the Lifebook starts charging itself from the mobile phone battery, which is obviously not what I want.
Is there any way of controlling the direction of power flow, or temporarily disabling the supply of power to the Lifebook via the USB-C port?
