Not that long ago, I noticed that the light on my TBT4-UDZ dock was white, not green. Didn’t know what to make of it, but could still reach my USB hard drives. Network was connecting via wireless, not the dock.
Yesterday, woke up to a dead laptop.
Unplugged the dock and plugged in the brick. Laptop started, checked out.
Tried plugging the dock back in. No power; laptop stayed on battery. White light started blinking slowly. Unplugged everything else from the dock; no change. Looked at Device Manager. Appeared that the blinking coincided with an attempt to connect to one of the three “superspeed” USB Ports.
Restarted laptop. Now, dock makes no attempt to connect when plugged into the laptop. Device manager shows no “superspeed” USB ports. USB4 Router reports device working. White light on, not blinking. No connection. No power charging. Nothing.
Additional info. Plugged the dock back in after filing the initial topic. Now, it is blinking from white to green, while the laptop beeps something connected, something disconnected.
