ThinkPad P51 / Thunderbolt 3 Dock

Q: ThinkPad P51 / Thunderbolt 3 Dock

I have a new P51, 64 GB ram, SSD hard drive. Ihave a docking station at work and one at home. The one at home has a 6 TB Seagate BarraCuda pro USB3 drive attached. When I dock the laptop at home, the system will not boot. It gets to the bios boot sceen and stays there until I turn off or disconnect the USB drive. Once I do that, it continues to boot and if I turn the USB drive back on, it works fine. If the drive is my old 1 TB barracuda, it boots normally.

Does the Thinkpad P51s support the Thinkpad Thunderbolt 3 Dock? I have the Thinkpad P51s with stock Windows 10 Pro and updated to latest drivers and Windows version and installed the latest Thinkpad Thunderbolt 3 Dock drivers. Attaching the Thunderbolt 3 Dock to the P51s as described in documentation, it charges the notebook, however, noting attached to the dock is recognized. I've tested with attaching USB flash drives, headphones, Ethernet, HDMI, and DP, but nothing is recognized nor are any warnings/errors displayed in Windows. While the Thinkpad Thunderbolt 3 Dock is listed as being compatible with the P51s and T570, the notebook order page does not list the Thunderbolt 3 Dock in any of the accessories lists. Lenovo Sales also confirmed that the Thunderbolt 3 Dock is fully compatible with the P51s.  However, I needed to purchase the Thunderbolt 3 Dock separately from the notebook order. What's going on? Has anybody successfully used the P51s or the T570 with the Thinkpad Thunderbolt 3 Dock? Or is this something I need to wait for full support via a future BIOS/driver update? Or perhaps my Thunderbolt 3 Dock is defective? Thanks,Boris

I have recently purchased both of the subject items.  I was informed via chat channels with Lenovo that the graphics dock would work with the X1 Yoga 3rd Gen.  However, upon connection, my Yoga recognizes that a Thunderbolt device has been connected but it does not recognize that a graphics card or USB ports exist.  Thus, my mouse, keyboard, and monitor do not work while connected to graphics dock.  I have downloaded and installed the drivers for the graphics dock but the result is still the same.  Does the graphics dock really work with the X1 Yoga 3rd Gen?  If so, is there a BIOS setting I must address to make this configuration work?

In the last month I purchased a Thinkpad X1 Yoga 2G and the Thuderbolt USB C dock. Since the USB C cable that comes with the dock is too short to allow the dock on the right and laptop on the left (in laptop mode), I put the notebook in tent mode and all works fine---except... Everytime I power up from hibernate it starts beeping about once a second and does not stop. I have to disconnect from the dock, flip it to laptop mode (this is where the beeping stops), return it to tent mode, and then plug the dock back in. It seems that Lenovo, like everybody else, is rushing things to market with plans to fix bugs later (maybe). Any thoughts I how to stop the beeping?  The first time it happened I closed all the apps to reboot and it still was beeping. Thanks.

Thinkpad Thunderbolt 3 Workstation DockEU/INA/VIE/ROKModel name: 40AN0230EULink (US version) I didn't find any decent pictures and or specs about this dock for the P series workstations, so here you are some pictures.It has a special combined cable, that allows to attach the powercable and the Thunderbolt cable in one. On the P1, P52, and P72, the sockets for the power adapter and the Thunderbolt are arranged the same way that the cable can plug in exactly. This is a simple and clever solution I think. The dock arrives with:230 W power adapter (which is for the P72 necessary, the P52 and P1 can use smaller ones), and I think is a simple pass-through from the dock to the laptop.65W power adapter - which is for powering the dock itself Downsides:The dock's cable is only 60 cm long, so there is not enough length to hide the dock (I think this is related to display data on Thunderbolt - can someone confirm?)And that the cable can be plugged in in one direction, so it will determine how the laptop and dock can be positioned relative to each otherConnections:USB: 5Thunderbolt: 2Audio: 1Network: 1Lock: 1List price is 392? in Belgium.

We purchased a new X1 Carbon 6th Gen with the new Thunderbolt 3 Dock Win 10 1803 and have had all kinds of problems. Bad enough to consider other brand alternatives. All Lenovo drivers are current, we updated the firmware and drivers for the dock. With that we still have the following problems and dont know how to resolve them1. The network connectivity from the dock to laptop with USB-C loses connectivity on occasion. Also when the user shuts off the laptop, comes back and turns the laptop on, no network connectivity is re-established. The only way to fix this is to unplug the USB-C cable and plug it back in. Sometimes that will lock up windows and we have to do a hard shut down and start of the laptop. 2. Running the display out from the dock is not always reliable. The monitor will turn off randomly. To bypass this issue we have to just plug the monitor directly into the laptop. 4. Occasional random bluescreens with a stop  code DRIVER_VERIFIER_DMA_VIOLATION. This error is related to bad drivers.Are we missing something. Is there anything we have to set in the BIOS to resolve these problems? I've been reading up on this dock and a lot of people are having problems with this dock and carbon 6th gen laptops

Hi, I'm using a Thinkpad Pro dock with an L470 on Windows 10(both brand new). I have a VGA monitor and a DVI monitor connected, and I can output to both screens as well as the laptop display just fine, however as soon as I undock, or switch off the laptop, when I come to use it again, neither of the screens are showing as connected. I have to unplug them from the dock and plug them back in again, at which point they are recognised and work fine... until next time I have to undock/switch off. I have tried this with a different laptop (also L470, but running windows 8.1) with even worse results. On 8.1 the screen will repeatedly flicker for about 10 seconds, and any combination of the screens will work (sometimes just the laptop screen, sometimes just 1 monitor, sometimes all 3). Even when all 3 work, it rarely has the correct resolution, and takes several attempts to get it working properly. The whole point of having a dock is that there is no need to keep plugging things in every time you sit down, if I have to re-plug the monitors every time it is pretty pointless having a dock in the first place. I have updated the BIOS on the laptop, updated every driver, updated the firmware for the dock and Windows 10 is bang up to date. I'm about out of ideas now and was wondering if anyone had any ideas on a fix for this? I see web searches that this is quite a common issue, but most of the "fixes" are what I have already done, or are specific to Windows 7 or 8... Read more

A:Thinkpad Thunderbolt 3 docking station does not charge Thinkpad P51 battery.

Everbody's p51 would be the same.  The thunderbolt port won't work as a charging port.  The thunderbolt specs specify 100w max.  That's not enough.  Your thunderbolt port is not for charging.  To charge via the dock, you need a workstation dock, not a thunderbolt dock.  A thinderbolt dock can charge things like an x1 carbon (5th gen) or x1 yoga (2nd gen)

As the only docking solution available and moving from a more traditional dock, its less than suitable.  HP needs to make a longer cable and the end that connects to the laptop should be at a right angle.  The cable is so stiff and thick it takes nearly 4" to make the turn.  HP makes it impossible to find this out how long the cable is with out purchasing and at that point your stuck with it.  Hardly a customer satisfaction issue they should want to propigate!

Hello all,I bought a Yoga X1 2018 and during the shop they suggest the Lenovo Thunderbolt 3 Dock. Since I thought that having to disconnect only one cable when bringin the laptop from the desk to the meeting room would have been useful, I bought it.With my disappointment I setup everything and I did some tests on the laptop just to discover that the performance of the laptop when powered through the docking station are 1/3 with respect to when it's powered by the 65W power supply and 1/2 of when the laptop is on battery... (234pt vs 640pt vs 563pt | dock/65W/battery)Now since the docking station has a 135W power supply, I really can't think that this is an issue with the supply from the docking. Also since the laptop is even faster on battery I really don't understand how it could be related to the power supply... anyway I've connected both the 65W power supply and the docking and the performance are back to normal.Is there anyone who can suggest me what's going on or how to report this to Lenovo?

I have installed the Thunderbolt software from the P50's driver site and updated to BIOS 1.17.Lenovo released an "Intel Alpine Ridge Thunderbolt Firmware" for the P70. But there's no such firmware update on the P50's site, just the Intel Thunderbolt Software from November.The 1.17 UEFI/BIOS Update says it fixed a Thunderbolt issue, but apparently not mine Has anyone ever gotten some Thunderbolt 3 device working on the P50? I just hope this will be fixed soon, because the Thunderbolt dock seems to be the only convenient way to drive three 4K displays with the P50 (2 via Thunderbolt 3, 1 via miniDP).

On all our laptops using the "old"-type dock, that you click your laptop into everything is working fine, the users put the laptops into the dock, turn it on, type in the Bitlocker PIN using the external monitor and keyboard, and then processed into Windows. Our problem is with everyone using the new Lenovo ThinkPad Thunderbolt 3 Dock. When the users connect the laptops to the dock using the cable and then power on from the dock, the laptop will power on (the LED in the ThinkPad logo lights up) but the monitors and keyboard connected to the dock is not working, and then after some time the laptop will power off again. We currently use a workaround where the users power on, type in the Bitlocker PIN and login to Windows before connecting the laptop to the dock, but this not a proper solution. We have Enabled both "Thunderbolt(TM) device" and "USB device" under "Support in Pre Boot Environment" in the "Thunderbolt 3"-menu in BIOS, but it still doesn't work. Have anyone else experienced this problem?
