good luck! You, casually, not..

Docking solutions play a very important part in the world of business laptops, as they allow the user to transform their portable PC into a desktop-like computer without the hassle of plugging in many cables. Traditionally, business systems like Dell Latitudes, HP EliteBooks and Lenovo ThinkPads had a proprietary docking-port for a specialized mechanical dock at the bottom of the system.

In the last years though, those kind of solutions have started to vanish, as a bottom-port limits how thin you can build a laptop. Another "victim" of this trend: The recently released ThinkPad P52the newest addition to Lenovo's mobile workstation lineup. Different from those machines however, the P52 did not include a new mechanical docking-port on the side. Not many details about this new accessory have been released, except for a picture showing that this isn't a traditional mechanical dock.

Instead, its a cable-dock. Thanks to the recently released userguide for the ThinkPad P52we have obtained some additional facts about this new dock. The ThinkPad Thunderbolt 3 Workstation dock is indeed a cable-dock with a single cable to connect the dock with the laptop. Lenovo achieves this by melding Thunderbolt 3 and the proprietary Thinkpad Slim Tip charging port into a single cable.

Curiously, the dock requires two chargers, one to power the dock and one to power the laptop. As for the capabilities of the dock, it has plenty of ports. On the front, the dock has one USB 3. On the back, there are four additional USB 3. The dock also provides security and convenience features: On the side, there is a Kensington lock and on the top of the docking-station, Lenovo has located the power button, which turns on the dock. The power button can also be used to turn on the connected ThinkPad.

We don't have a release date or a price for the dock yet. A release can't be too far away though, with the imminent release of the P As for compatibility, so far only the ThinkPad P52 has been confirmed to work with this dock, although we would expect that the yet to be announced After all, special docking-systems like this one are typically not made for just a single model.

Best Displaysfor University Students. Userguide ThinkPad P With the announcement of the ThinkPad P52 a few days ago, Lenovo also announced a crucial accessory, a new dock. But the company didn't release too many details about this dock, besides is name. Thanks to the ThinkPad P52 manuals, we can now take a closer look at this new dock and its specifications.

In all the cases we have seen so far, the cause was determined to be that the Thunderbolt device lost its authentication status in Windows during the OS update. While video outputs will always function regardless of authentication status, the USB ports, Ethernet port and audio port will not work if they are not properly authenticated.

If things stop working as expected, the best path forward is to uninstall and reinstall the Intel Thunderbolt software with an updated version if available to help ensure that the Intel Thunderbolt software that controls the authentication process is in a good state. To do so, follow the steps below:.

ThinkPad P52 TB3 Dock

The first time I was away from my computer for an extended period the whole thing locked up. The screen was blank on the monitor. I moved the mouse and the monitor screen did not wake up. I opened the laptop lid and could see the screen. When I closed the lid the external monitor came back to life, but the mouse and keyboard did not work.

The computer was locked. Is the Workstation Dock firmware up to date?

Top Kudoed Authors User kudos. Stay in touch Our commitment to the environment Lenovo is committed to environmental leadership from operations to product design and recycling solutions.I receive a message on the laptop Windows 10 that the power supplied from the dock is insufficient.

I feel this should be a sufficient configuration and power supply to power the laptop while connected to the dock. Do I need a more powerful supply? Or did I miss some sort of configuration somewhere? Or is there a hardware problem? Something else that I haven't thought of? I don't want to connect any more than I have to when arriving at work for the day, and there is a shortage of power sockets anyway, so solving this problem is important for me.

I've also noticed that the USB-C cable has the number 3 printed on each plug, next to the power sign lightning markand I wonder if perhaps this means it is a 3A cable delivering a maximum of 60W, which may be to little for the P52? It may charge using USB-PD while powered off, but it would be slower than using the correct charger, and you would want to keep a close eye on it while it does charge to make sure nothing overheats. If there are two USB cables, which are able to deliver up to W, will the P52 and Thunderbolt between them figure out how to balance that?

The has two PSUs 65W and W and one integrated cable to both power the workstation and supply signal. It seems I need to get a W power adapter for the dock, using the W adapter for travelling. But at least I now know that I have the correct dock version. It came cheap, without a power supply Have you tried that? I really doubt that this can work, but please leave a note about your results. Remaining power adapter - W I plan to leave in backpack it's bit smaller than W.

I hope everything here should work as I expect :. Yes, this setup sounds good. Once I had the right dock Gen 2, the one with two power input sockets I was away and running.

I also have a Gen 1 dock at home, and I have a 65W power supply for that, and then a spare W supply for the power directly to the laptop when using the Gen 1. This is almost the same as what you are proposing, and it works fine. View All. Lenovo is committed to environmental leadership from operations to product design and recycling solutions.

This can happen when the connector is slightly turned to one side, and the power connector does not connect. It is very easy to cause.

When connecting push the left side of the connector to make sure it is fully connected. When you connect a Thunderbolt 3 dock for the first time to the computer, you must approve the TB3 connection to the dock. 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 sort of security requirement, so that it would not be easy to connect complex devices into the computer.

Often a popup will appear to approve the device. You can choose to approve this device forever, or just once.

But this popup will not always appear. Solution: approve the device from the popup, or go and manage approved devices in the Thunderbolt 3 software to approve this device. I wish I could create custom aliases for the devices. Having the same dock at home and at work shows the same name for both.

There are multiple solutions to this one though:. Solution 1: Reconnect the dock. Solution 2: Power cycle the TB3 dock. Remove the 65W power connection from the dock itself, and then reconnect it.
