I have a DELL TB18DC docking station connected to my DELL laptop and everything seems to be working fine except for my USB connected mouse which is currently failing to work as it should. Problem is that it lags ... just like if it loses its connection for a split second which is very annoying.

Currently I have tried reinstalling all the related drivers and also updated the drivers, connected a different mouse (both of the mice are working fine when connected to my laptop itself). The problem still persists. I don't seem to get any answers from DELL and therefor I am trying to find them here.

How do I fix the problem?

  • I have the same dock on my Precision 3520. Do you have Dell SupportAssist installed? And if so, has it identified any updates to install? – spikey_richie Oct 19 '18 at 12:56
  • No, I have not. I am working with a company laptop and we have been adviced not to install any software that is not approved by our IT department. Also apparantly DELL is not willing to give us support because our laptops are not running the orginal windows (10 enterprise) copy anymore. We are running a copy of windows 10 enterprise with user profile control etc. – lucasdm303 Oct 19 '18 at 12:59
  • OK, then via the Dell support page there's a web-based system scan you can run which doesn't depend on SupportAssist being installed. Using that, does it suggest any updates? – spikey_richie Oct 19 '18 at 13:00
  • The issue persists after updating – lucasdm303 Oct 19 '18 at 13:02
  • Have you tried one of the other USB ports on the dock? – spikey_richie Oct 19 '18 at 13:36

SOLUTION ----->

In BIOS: Under System Configuration\USB Powershare Disable USB Powershare. Under Performance\C-States Control Disable C-States

EDIT: STOPPED CHARGING AND FUNCTIONING COMPLETELY DO NOT BUY THESE THINGS

Updating the firmware of the dock helped my issues partially.

Here's a thread on how to do it. https://www.dell.com/community/Precision-Mobile-Workstations/TB18DC-Driver-Update-Not-Easy-to-Find-so-here-it-is/m-p/6210686#M884

Although, I don't like this dock, mainly because of the constant fan noise.
