Fans not working, abnormal, or loud fan noise, overheating?
Loud or fast-spinning fans and overheating can result from blocked air vents, dust buildup, poor ventilation, physical damage, or outdated BIOS and drivers.
Fan noise heard when the AC adapter is plugged into the dock?
When plugging in the AC adapter and powering on the docking station, the fan turns on for some time and subsequently turns down. This is by design and docking stations are working as expected.
What is the charging station feature?
The Dell thunderbolt Dock WD22TB4 can charge your phone or other USB-powered devices even without being connected to the system. However, the ac adapter must be connected the the docking stations for this to work
Why do the peripheral devices connected to the dock station become unresponsive after recovering from a power loss?
The docking station operates only on AC power and doesn't support power from the system's Type-C port. A power loss disconnects all devices and restoring AC may not work until the AC adapter is disconnected and reconnected to reset dock's connection
