Constant disconnects with Dell XPS 15 laptop and Plugable USB-C Triple Display Docking Station


#1

After reading the Plugable FAQ to check for compatibility, I just bought a brand new Dell XPS 15 (6560) laptop and a Plugable USB-C Triple Display Docking Station, but I’m having the issue with constant disconnects making the dock completely unusable. I’ve searched the web for a resolution and have tried all the recommendations I could find, e.g. I’ve installed the Plugable DisplayLink drivers, I’ve updated to all the latest drivers and BIOS from the Dell website (including Thunderbolt & Graphics), I’ve tried switching to Wi-Fi Airplane Mode, I’ve tried closing the laptop lid, etc., but nothing works. It just keeps constantly disconnecting and reconnecting every couple of seconds. My monitors are 2 Lenovo ThinkVision LEN L201p 1600x1200 monitors with brand new Cable Matters DVI-D -> HDMI six foot video cables. The dock is connected to the laptop through the USB-C to Thunderbolt 3 port. I am desperate to get this working, so I hope Plugable can find a resolution. Thanks, Craig

Have you tried connecting the original laptop power supply? I had the same problem with the same model laptop, 9550 in my case. When I connected the power supply, the disconnects stop. I am not saying this is a solution, but it may be a work-around.

Hi Craig,

Thanks for posting! I can see you have also reached out to us directly via support@plugable.com and I have just sent my direct reply. Please only respond to my direct reply so we can keep all information in the same place.

For the benefit anyone else following this thread, sending a one of our PlugDebug files (http://plugable.com/support/plugdebug) to support@plugable.com allows us to examine details about your system to help us determine the next steps.

If you have a Thunderbolt 3 system as Craig does, including a screen shot (http://www.take-a-screenshot.org/) of the Thunderbolt 3 ‘Details’ information from your system by following the steps under the “How do I check which version of Thunderbolt 3 software and NVM firmware I am running in Windows?” from this link -> http://plugable.com/thunderbolt-3/sup… is also very helpful.

Thank you,

Bob
