UD-3900 no longer recognizing monitors after power cord disconnect

I have been successfully using my UD-3900 connected to a new HP laptop with two non-HDMI monitors. Monitor 1 is DVI and Monitor 2 is VGA with a USB connector plugged into the dock.

Today, I disconnected the power supply from the dock. Upon reconnection, the doc boots up and shows connection to my laptop. However, neither monitor is detected. I’ve rebooted, and am not sure what else to try.

Hi Dave,

Thank you for contacting Plugable! I am sorry to hear that your UD-3900 docking station is not functioning as expected, and would be happy to provide additional support.

To help diagnose the issue, may I ask you to please keep the device connected to your laptop and everything still attached (even if not working as expected) and send us the output of our diagnostic utility PlugDebug? → https://plugable.com/pages/plugdebug

Once you have the logs, simply send an email to support@plugable.com with the subject line of “Ticket 356698” so that we can prioritize that case and match it to this inquiry.

If you could provide your Amazon Order ID (or other proof of purchase) associated with your Plugable device, I would be happy to check on your warranty status as well.

Thank you for giving us the chance to help!
