How to Fix “Multiple Docking Stations are not simultaneously supported” Error

The error message “Multiple Docking Stations are not simultaneously supported. Disconnect additional docking stations.” appears during startup if you have recently upgraded your Dell docking station.

To fix this error, first, disconnect your dock and power cycle it. Then, reset your laptop’s BIOS and reconnect your dock.

Don’t worry! I am going to explain each of the above steps in detail.

Step 1: Disconnect and Power Cycle your Dock

The first step is to power cycle your Dell dock. Here’s how to do that:

  1. Disconnect the docking station from your laptop.
  2. Unplug the AC power from your docking station.
  3. Press and hold the Power button for about 1 minute to drain the remaining power from the dock and clear its cache.

Step 2: Reset Laptop BIOS

After power cycling your docking station, the next step is clearing the BIOS logs and restoring it to its factory settings. Here’s how to do that:

  1. Restart your laptop. On the boot or Dell logo screen, press F2 key several times.

Alternatively, you can press the F12 key and then select System Setup or BIOS Setup option from the menu. See the screenshot below:

  1. When in BIOS, go to System Logs. Select BIOS Events in the left pane. Click on the Clear the logs options. (See the screenshot below).
  1. Next, click the Restore Settings button to restore your laptop BIOS to the factory setting.
  1. Now, reboot your laptop.

Step 3: Reconnect the Dock

Once your laptop reboots, connect your Dell dock back to your laptop.

For a proper connection between your docking station and laptop, connect your monitor and other devices to the dock.

After that, plug in the power cable and turn on the dock.

Only use the power adapter that came with your docking station.
