ThinkPad Thunderbolt 3 Workstation Dock troubleshooting - https://cmcdistribution.com.vn/en

This article shows some common problems I have run into with the ThinkPad Thunderbolt 3 Workstation Dock. If you want to read about the pier itself, you will find a separate review about it here. Some of these tips apply to other docks as well, but I write them from the perspective of the TB3 Workstation Dock and a ThinkPad mobile workstation ( like the ThinkPad P52 ) .

Problems and solutions

Not charging

sometimes when you have connected to the dock, it will still not charge the notebook .
This can happen when the connection is slenderly turned to one side, and the exponent connection does not connect. It is very easy to cause. sometimes the initial connection is not that good, then again sometimes moving the notebook slenderly on the table can cause this .
It is easy to fix, but equally easy to miss. I have respective times wondered, why my notebook is losing battery just to realize that there is no office joining.

Sometimes the dock software will warn me that no power is connected, but the warnings are not consistent.
The warning do not seem to appear if I hibernate the notebook and then wake up connected to the dock.
The software sometimes produces false alarms if you have charging thresholds set in the computer. In this case, the lack of charging is intentional.

Solution: Make sure the cable is constantly well connected. When connecting push the left side of the connection to make sure it is fully connected .

Recommendation to Lenovo:

The dock software should check to see if a dock is connected EVERY TIME the computer is turned on, wakes up or starts up from hibernation.
The dock software should recognize charging thresholds to distinguish between a real unconnected power issue and charging thresholds preventing charging (both software come from Lenovo, integration should not be a problem)
The docking cable’s end that connects to the computer could be designed to better align with the notebook. Slight indent on the notebook itself? Small light to indicate both TB3 and power connection (on the cable, not the notebook).

Thunderbolt 3 approved devices

When you connect a Thunderbolt 3 bobtail for the first time to the computer, you must approve the TB3 connection to the pier. If the connection is not approved, the dock will not function. Devices connected to the dock will not be connected to the computer. I imagine this is some screen of security requirement, so that it would not be easy to connect complex devices into the calculator .
often a popup will appear to approve the device. You can choose to approve this device forever, or barely once. But this popup will not always appear .
Solution: approve the device from the popup, or go and manage approve devices in the Thunderbolt 3 software to approve this device .
I wish I could create custom aliases for the devices. Having the lapp dock at home and at work shows the same name for both .

Peripherals not recognized

sometimes peripherals will not be recognized by the pier. This means both displays and USB devices. For USB devices, you can try to connect them to other USB ports on the pier, and still they fail to be recognized. This is different from the dock not being marked as approved .
It can besides be very annoying that I connect my ThinkPad P52 to the dock, turn it on, and can ’ deoxythymidine monophosphate type on the external ( USB ) keyboard. There are multiple solutions to this one though :
Solution #1: Reconnect the dock. Remove the TB3 / docking cable, and connect it again. This solves the problems about 40 % of the time .
Solution #2: Power cycle the TB3 dock. Remove the 65W office association from the dock itself, and then reconnect it. This normally solves the problem with a 90 % find .
Solution #3: If neither of the former steps worked, try rebooting your notebook.

Solution #4: Update the dock firmware and software

Software updates

If you have problems with the dock, check for firmware and software updates regularly. You can find them on the surveil page at the Lenovo support site .

notice that the instructions do not tell you this, but after the dock firmware has been updated, reboot your computer and reboot the dock american samoa well ( by removing the exponent to the bobtail, and reinserting it ). Otherwise, it will not function by rights. besides, before you do this, some extra updates ( like the audio firmware ) will refuse to install .

TB3 software update

Lenovo Vantage will besides want to update the Thunderbolt 3 software sometimes. It might be a commodity mind to NOT DO THIS together with a firmware update. Perform the firmware update of the dock individually, then reboot both your calculator and the bobtail .
differently, you might end up in a situation where the Thunderbolt 3 software on the notebook might fail to install. It fails mutely ( at least if you used Lenovo Vantage to install it ), leaving you in a express that your dock just does not work. This is a confuse position, because everything seems to be connected OK, and so far, nothing works, and there are no erroneousness prompts or anything .
solution : Reinstall Thunderbolt 3 software. If facility failed, Lenovo Vantage will offer up facility again. Try again, and make sure to check in the installation history that the install went oklahoma .
