HP Thunderbolt Dock G2 Not Working – How To Fix It?

If you have encountered an issue with HP thunderbolt dock G2 not working, the first step is to diagnose the problem while referring to the user manual. In general, most issues with Thunderbolt Dock G2 happen due to the connectivity issues between the docking station and the device.

Refer to the steps and guidelines below after checking the basic hardware connection.


Reasons for HP Thunderbolt Dock G2 Not Working

Reason 1.

Sometimes, when the user has been away from the desk for more than an hour, the laptop doesn’t react to the keystrokes or mouse strokes. If the issue happens when you AFK (away from the keyboard) open the lid and manually press the laptop’s power button.

It also behaves the same way in the semi-sleep mode. As the laptop is still placed on the dock that comes with up-to-date firmware, you may come across several connectivity problems. 

Reason 2.

The laptop utilizes a USB-C connection with the external screen via the display port, and it usually works fine. But, within a few days, you may come across several issues regarding its connection and functioning. In that case, you have to check whether the external device authorizes the Thunderbolt device before establishing the connection. To do that, follow these steps.
