I reset it using this method in both cases, usually having to cold boot the computer as well.Ģ) I don’t think it’s that unusual that holding a power button down while power is off resets electronic devices. Or I had my wacom tablet during a call and the dock shuts down. Zoom seems to have a memory leak in Linux and over the course of a day my memory gets used up and everything freezes. I don’t want to say maybe something more serious happened, but that’s always a possibility.Ī comment on a couple of things people have been saying:ġ) I actually use this all the time, maybe daily. Dan (Sun (12:34:29)) I’m afraid I don’t know the answer if this doesn’t work.Wow! Seems counter intuitive, but it works! The 45 second hold down of the power button. I took a power hit and this procedure worked for me. Suggestions? BTW it simply stopped working Trying the TB16 fix and it won’t work – no light on thunderbolt cable no matter what. I admit i was skeptical, but thought why not, can’t hurt And the main reason i purchased this quite expensive dock was to plug the monitor into it The monitor kept saying that it could not detect the signal on the HDMI line. I had a monitor plugged into the HDMI port on the dock. Thank you so much! This worked on my Dell WD19TB dock. Why is this on an English professor’s website? It works by the way… Now tomorrow I will be going back to micro Center and returning that docking station that I purchased. I found your article later and tried your method and it worked seamlessly. I actually went and purchased another docking station and it would work with one of my laptops but not my work laptop. I may need to put the dock power brick on UPS. I believe temp power drops (storms) resulted in my issue this morning. I will try that the next time the light won’t light. They are just convenient for manufacturers one for all even though power requirements make that null and void now (TB16 vs TB18).

I would use the TB18, though I doubt it’s different, but that has other USB driver issues that cause blue screens. Press the dock button for a second and system should boot normally. Power light on TB connector should come back on now.
The other option that I found was, unplug the power and laptop TB connection. I have typically had the same problem every once in a while as well and still do. I did not know about the 45 seconds on the power button. Thanks very much, you saved my day here in Argentina I thought the Thunderbolt was fried, and Dell documentation was no help. Thank you just experienced an electrical event, and even though my devices are protected, the Thunderbolt flickered off while my computer and other peripherals did not. Thank you so much for posting this to help others like me!Īmazing thanks so much for this, the dock was unresponsive this morning and this has just recovered it!! Tried your instructions and they worked like a charm.
Just had a power surge and thought for sure I had fried my TB16. Thanks man!! That worked for me after a power outage I thought it was fried. Thank you so much for posting this! We had a power outage and I was worried it was fried – but this worked – champion :-) This worked for a WD15 dock as well, thank you! Not clear how holding the button down on the dock works after the power supply to the dock has disconnected. What I do in that case is unplug and replug each of the cables going to the screen in turn. Even after the computer and dock have been reset it doesn’t seem to see the screens. Sometimes, my computer doesn’t seem able to read or recognise screens through the dock (this often happens when I get the peripheral crash discussed above). Hold the power button on the dock down for 45 seconds.Unplug the dock from power and from the computer.
#DELL THUNDERBOLT DISPLAY HOW TO#
In a chat with a tech, they told me how to reset the dock (I don’t see this anywhere obvious on the Dell site): Looked through the Dell troubleshooting guide and found nothing. This afternoon I came back from a meeting and my computer was hibernating and the dock was dead: no power light, no light on the Thunderbolt cable, no response to commands, and no screen, sound, or internet pass through. But I use it quite often to reset the USB for peripherals (I have a real problem adding tablets ( WASCOM or Remarkable) or phones (Android) via USB via the dock: it somehow seems to kill the dock’s ability to work with peripherals and then I use this to reset it (while rebooting the computer)). This one I discovered when the dock was “bricked” (i.e.
