Dell Precision 7×50: Double docking stations usable again with BIOS update

Hopefully anyone using a Dell Precision 7750 or Precision 7550 notebook in combination with dual docking stations can breathe a sigh of relief: docking stations like Dell’s own WD19DCS (starting at €196.72) didn’t work for a month when they had two USB-C connections to the notebook. A BIOS update to version 1.25.0 should now help.

The previous version 1.24.0 prevented the simultaneous use of both USB-C ports on a docking station. In the case of the WD19DCS, only the LED on one port lit up. Due to the halved bandwidth, not all connections on the docking station worked, and some external displays only ran with a reduced resolution and refresh rate. In the official Dell forum, numerous users also reported charging problems because the WD19DCS was no longer supplying enough power.

Automatic and manual updates

Unless configured otherwise, notebooks automatically download and install new firmware versions. Dell also makes BIOS update 1.25.0 available for manual installation via its website. If you use a Precision 7750 or Precision 7550 at work and are having problems, you should contact the admins about the firmware update.

However, it currently remains unclear whether the BIOS update will completely resolve the problem. Some people report that not all connections still work correctly. Those still affected can try disconnecting the WD19DCS docking station from the notebook, pressing and holding the power button for half a minute and then reconnecting it to the notebook.
