1. The fan is not working after connecting with the system.
● The fan is triggered by temperature. The dock fan will not rotate until the dock is hot enough to trigger a thermal
threshold.
● Vice versa, if your dock is not cool enough, the fan will not stop even when you disconnect the dock from the system.
2. The dock does not work after high-speed fan noise.
● When you hear a loud fan noise, it is warning you that the dock is in some kind of a hot condition. For example, the
vent in the dock may be blocked or the dock is working in a high working-temperature environment (> 35C), etc,.
Please eliminate these abnormal conditions from the dock. If you do not eliminate the abnormal condition, in a worst-case
situation, the dock will shut down through the over-temperature protection mechanism. Once this happens, please
un-plug the Type-C cable from the system and remove the dock's power. Then wait 15 seconds and plug in the dock
power to recover the dock back online.
3. I hear a fan noise when I plug in the dock's AC adapter.
● This is a normal condition. First time plugging in of the dock's AC adapter will trigger the fan to rotate, but it will
subsequently turn off very soon.
4. I hear a loud fan noise. What's wrong?
● The dock fan is designed with five different rotate speeds. Normally, the dock will work on low fan speed. If you put the
dock in a heavy loading, or in a high working-temperature environment, the dock fan may have a chance to work at a
high speed. But, this is normal and the fan will work at a low/high speed depending on the work loading.

5. What is the charging station feature?
● The Dell Docking Station WD19 can charge your mobile or power bank even without being connected to the system. Just
make sure your dock is connected to external power. The dock fan will rotate automatically if the dock gets too warm.
This is normal working condition.
6. Why does the hardware installation window show up when I plug in a USB device to the docking stations ports?
● When a new device is plugged in, the USB hub driver notifies the Plug and Play (PnP) manager that a new device was
detected. The PnP manager queries the hub driver for all of the device's hardware IDs and then notifies the Windows OS
that a new device needs to be installed. In this scenario, the user will see a hardware installation window.

7. Why do the peripheral devices, which are connected to the dock station, become unresponsive after recovering
from a power loss?
● Our Dell dock is designed to operate on AC power only and it does not support system power source back (powered by
system Type-C port). A power loss event will make all devices on the dock fail to work. Even when you restore the AC
power, the dock may still not function properly because the dock still needs to negotiate proper power contract with the
system's Type-C port and establish a system EC-to-dock-EC connection.
