ThinkPad Pro Dock, ThinkPad Ultra Dock, or ThinkPad OneLink Pro Dock - External Monitors

Question: ThinkPad Pro Dock, ThinkPad Ultra Dock, or ThinkPad OneLink Pro Dock - External Monitors

I have a simple question, Can I run 2 external monitors using the Ultrabase series 3 with the X230 docked and the lid open? My goal is to be able to see basically 3 displays. The main one would be the laptop and the other two extended monitors connected to the dock stations. One connected with VGA cable and the other with display port cable. Any help is appreciated.

Hi, Everyone. Got me a nice little x270 to replace my old x201.  Happy enough with the machine, but getting it connected to my accessories (monitor, keyb, mouse, ethernet) is a bit of a chore. This machine appears to have a "proper" dock port on the bottom.  Is there a compatible ultradock available for the model 20HN x270?  By proper - I mean, Not USB.  A nice dock I can simply drop the machine into when I'm at the home office.. Thanks!

Hey guys,I've got new P50s (running W10 x64) with Quadro M5000M, and Ultra docking station for it. I want to use 4 external monitors in any configuration, just that they all work. I tried updating BIOS and Docking station, installed latest Intel and Nvidia graphics driver, power management driver.. everything.I get 4 monitors displayed in Windows display settings, but as soon as I turn on the fourth, one of the others goes dark. Somewhere I read about BIOS setting for Hybrid graphic, but I don't have such setting in BIOS. Any help would be great Thanks!

I have the exact same equipment at home and at work and yet the resolution on my second monitor at work will not go to the 3840 x 2160 that I have at home. Both locations have:1. X1 Yoga (first gen, model number 20FQ002YUS) -- It's the same laptop that I take between home and work2. ThinkPad OneLink+ Dock (model number DU9047S1)3. Two (2) Asus monitors (model number PB287Q) that go to 3840 x 2160 max resolution, connected to the OneLink+ Dock via DiplayPort cables I've been running this configuation with NO PROBLEM at home for the past 9 months.  So I recently purchased a new OneLink+ Dock and two new monitors for my work office and while one monitor will go to 3840 x 2160, the other will not go above 1920 x 1080, UNLESS, I use a mini DisplayPort cable from the second monitor directly into the X1 Yoga (bypassing the OneLink+ Dock) HERE'S WHAT'S BAFFLING: I assumed it was the dock and so I brought the one from home to work and found I had the SAME problem, suggesting it was the second monitor.   But I exchanged the second monitor for a new one and still have the same problem.  The docks are running the most current firmware. I'll send a gift card to your favorite coffee house if you can solve this mystery.  Thanks!

I have tried to connect my two external monitors to the dock (the one connected to the vga port) but it was only able to detect one of them (though at a low resolution) and not the other. i have tried using a replicator to connect the screen to the dvi and the usb  ports but nothing seemed to work Did anyone face the same problem and how were they able to resolve it - any recommendation for a port replicator brand / usb to vga display adapter to use that would work? Thanks

Answer:Three external monitors + own LCD in W540 with nVidia K2100 in ThinkPad Ultra Dock

Hi Nicolas! Is there a docking station involved? Probably there is( two DisplayPorts), but is it compatible model? What about monitors then? What  is the manufacturer and type? What about monitor selection (f7 without Fn button or Fn lock) have you selected appropriate selection (Clone, extended)? You could refer  posting "W540 external display issue", I struggled with similar problems, an the main reason was the docking station and odd cable behavior and of course tha HP display of mine. It seems to me that this machine is very sensitieve when talking about cables and connections. I would start adding one at time and repeating until I got a black screen. It is much more easier to find the reason that way. Regards-Alpo-

Since upgrading to from Windows 8.1 x64 to Windows 10 x64, the two Dell U2713H monitors plugged into the dock (via the two Displayports)  have stopped turning on after the power saving option of turning off the monitors has been activated. Powering the monitors off then on does (most of the time) resolve the issue, however in doing so the desktop layout of all the applications that were opened at the time is messed up (all application windows have been resized smaller). This problem has only occurred since upgrading to Windows 10. I have installed the latest video drivers (Intel HD 4600/Nvidia K2100M) available from the Lenovo website. The dock have the lastest firmware 2.22. Anyone else had this issue and if so, have you been able to resolve it?

Answer:ThinkPad Ultra Dock and External Monitors post Windows 10 upgrade

Hello, I have had the same or similar issue on a W540.  I have two SamSung 2443's attached to the dock.  Has worked pretty flawlessly under 8.1 x64, but I get unpredictable behavior when re-docking under Win 10 x64. Sometimes the monitors are not recognized until I go into the Intel Control panel (which is odd in itself, because it doesn't seem like it is using the NVidia card).  Occasionally it will hang and crash with DPC_WATCHDOG_VILOATION errors.   I am updating to the latest 353.82 NVidia driver and am continuing to troubleshoot and post back if I find a recipe that works.

I am running a IBM Thinkpad W540 with a Lenovo Ultra Dock Docking Station 170 (Model 40A20170US). I have 3 Asus 23.6" LED HD Monitors (Model VN247HP). These monitors have a standard VGA connection and 2 HDMI ports, By default you are provided a VGA cable and a HDMI-DVI cable. When I plug these monitors into the Ultra Dock no signal is found(including the VGA).When I plug into the direct VGA port on the laptop, the monitor gets signal. If I use a Mini-DP connection with a Mini-DP-DVI adapter I get signal just fine. If I plug my this monitor into my desktop under HDMI and DVI connections it works just fine.I have gone into the bios and confirmed that under display the "Video Mode on Dock" is set to Advanced(I tried standard and it did not work any better).  I have the latest video drivers for the Intel HD graphics driver (10.18.10.3412) and the NVIDIA Quadro K1100M (9.18.13.4052). The USB ports work just fine, as does the power cable for the docking station. I tried applying the latest firmware update but the program runs and nothing happens. I checked for any other drivers thatmight have resolve the issue but have not had any luck.I tried calling for support on this (since its a new purchase), and the phone support said they could not help me, but they directed me here.

Answer:ThinkPad Ultra Dock Docking Station 170 not providing any signal to external monitors.

I am really sorry you are experiencing such issues. What makes me really mad is the fact, according to your words, that Lenovo support is directing you to this forum for help? This forum works on volunteer basis, so you might have a luck or not. I mean, you are living in the USA which is the most important market for Lenovo so if I would you, I would escallate the support issue.Meanwhile, there are two options you might try out:You could check if the firmware utility driver update helps, http://support.lenovo.com/us/en/documents/pd028011or you might try out your luck with the native nVidia drivers, see http://us.download.nvidia.com/Windows/Quadro_Certified/334.95/334.95-quadro-notebook-win8-win7-64bit... .

Hello,I think of buying the ThinkPad T400 with one of these docking stations: ThinkPad Advanced Dock or ThinkPad Dock II.I have several technical questions and haven't found neither appropriate information, nor the way to get it.Here are my questions:1. Do these docking stations support DVI when T400 with integrated (not discrete) graphics is connected? 2. Where can I find a complete list of UltraBay devices supported by each one of these docking stations?Thanks

Answer:T400 with docking stations, ThinkPad Advanced Dock and ThinkPad Dock II

I have a T400 with integrated graphics and recently purchased the Advanced Mini Dock 250410U.  The Advanced Dock and Advanced Mini Dock support DVI pass-through.  I looked into this before purchasing as well.This page will confirm the feature:  http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-72148.  Also see reference guide for docking stations: http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-4TPJF4 which says ThinkPad Dock II is discontinued.  This brochure says the Advanced Mini Dock does not support Ultrabay, but the Advanced Dock does.  http://download.lenovo.com/ibmdl/pub/pc/pccbbs/options_iso/tp_docking_solutions_june09.pdf .

Hi, I've just setup my new Thinkpad Yoga with OneLInk Pro dock, and connected it up to my 2 external monitors (both through the dock, one via DisplayPort, the other via DVI).  I'm not having any resolution issues (which seems to be a common problem), but most applications are slightly blurry when viewed on the external displays (but crystal clear when viewed on the Thinkpad display).  This includes all Microsoft Office programs and Chome.  The only application I've tried so far which is crystal clear on all screens is SAS. I was wondering if this is a common problem, and if so, is there an easy fix? Thanks

My ThinkPad W541 in combination with the ThinkPad Ultra Dock is unable to detect my external microphone as I plug it into the headphone/microphone combination slot. According to the available specifications on the website, the dock should indeed include a combination slot for either headphone output or microphone input. Unfortunately, this does not seem to be the case. Although the output works, my external microphone is not detected. It does not show up under Recording devices and instead only lists Microphone Array, the laptop?s internal microphone. One of the threads that I was able to locate suggests reinstalling the audio drivers (Realtek in this case) while connected to the dock. This does not resolve the problem. Using the built-in microphone is not an option due to it capturing all of the surrounding noise (including its own noise), except the actual speech, and this for a ?high-end portable workstation?. Please tell me that I am at least able to use an external microphone (without involving another external device)? I find myself searching for many workarounds instead of actual solutions to many of the problems with this laptop, which is very unfortunate.

Answer:External microphone with ThinkPad Ultra Dock

Did you directly connect your microphone to the 3.5mm combo jack or did you use a suitable adapter? As far as I know, both the combo jack of the W541 and the Ultra Dock have the following pinout:Tip - Left AudioRing 1 - Right AudioRing 2 - GroundSleeve - Microphone

I hooked the one Acer monitor directly to the monitor port, and it works perfectly.  I then hooked the other through a Triton SS2 Extreme UV200 External DVI/VGA Video Card as was recommended for me to do so.  The Triton has a USB plug which I then connected to one of the USB ports on the back of the docking station, and loaded the software.  Everything worked great but the 2nd monitor screen enlarges everything.  So I though I could just go into the control panel and adjust that monitors settings.  However, the system is only recognizing the monitor in the monitor port of the docking station.  In the connection directions, it says the 2nd monitor has to be connected to the other USB port that is not standard and is on the far left of the back of the dock with an emblem the has 2 "+" signs stacked on each other followed by a bold "D" (I think).  I have tried to see if there is an adapter to convert the standard USB to fit this other port, and no one has been able to help me.  Does anyone have any recommendations, idea's or knowledge of how to work through this?  Thanks.

that is the Displayport, which can be converted to a DVI or VGA port using an appropriate adapter. But there is no USB adapter for the Displayport, as they use a different technology.

Answer:Unable to connect to 3 monitors to Ultra Dock (Thinkpad W540) in Advanced Mode BIOS Setting

So I fixed the issue for myself and just wanted to post in case somebody else had the same issue.  I took the following steps to fix the issue:[Background: BIOS is in "Standard" display mode to begin with; I had already updated the docking station's firmware first with a program called fwdphb03.exe and then with Lenovo's update utility.]1) In Windows, I uninstall drivers for the Intel Graphics and K1100 dedicated card.2) Restart, go into BIOS, switch to "Advanced" mode under the Display tab.  I also have the option selected to start up on the docks in the BIOS Display tab.3) Booted into Windows (8.1) and it looked like the Intel Graphics drivers were automatically downloaded. I then ran Lenovo's System Update utility to get the latest video drivers.  Under the optional tab in the Lenovo update utility, I selected the "Optimus" drivers and hit download/install.  It installed, and I had to restart.4) Booted into Windows again, ran Lenovo update utility again, and again it had a video driver to install when I checked for updates.  I installed that, had to restart again.5) Booted into windows, checked screen resolution and saw that no external monitors were showing.6) I then decided to get a driver straight from the source.  Downloaded: the following file from  Nvidia: 334.95-quadro-notebook-win8-win7-64bit-international-whql.exe.  I ran the installation, it did a "Clean" installation with everything checked off.

I have recently received an upgrade laptop at work. On my previous laptop (ThinkPad, unsure of model), I was able to connect one external display monitor directly to the VGA port on the laptop and an additional external diplay monitor to the ThinkPad Pro Dock station VGA port. I prefered to use these two screens with my laptop closed on the docking station, but could also open the laptop on the dock and have a third screen available. ISSUE: With my new ThinkPad (T440) there is no VGA port on the laptop. I have purchased a simple HDMI to VGA Converter Adapter - see link:https://www.amazon.ca/VicTsing-Gold-plated-Converter-Ultrabook-Devices-Black/dp/B016LVT51G/ref=sr_1_...   I am using the same ThinkPad Pro Dock station as with my previous laptop. With my new T440 I am able to work with my laptop open or closed on the docking station with one external display plugged into the docking station. I am also able to work with one external display plugged directly into my laptop using the VGA to HDMI converter adapter.  ISSUE 2: The laptop will not recognize when both screens are plugged in at the same time, but they each work when I have only one plugged in either to the dock or directly to the laptop. PLEASE HELP!! TIA

Answer:ThinkPad T460 - How connect two external monitors using dock station

A simple upgrade to your docking station will solve all of your problems. It sounds like you've got the Thinkpad Basic Dock, which only has one VGA port for video out. The Thinkpad Pro dock has a VGA, DVI, and HDMI out, and would be a good solution for you.https://www.amazon.com/Original-ThinkPad-40A10090US-Adapter-Lenovo/dp/B00G6T8EK2/ref=sr_1_2?ie=UTF8&...The Thinkpad Ultra Dock would also be good. It has two displayport ports, if you want to output to two higher resolution monitors.https://www.amazon.com/Lenovo-ThinkPad-Adapter-40A20090US-Packaged/dp/B00E0E2DIE/ref=sr_1_1?ie=UTF8&...Upgrading would also make setting down at your desk a lot easier with only one thing to plug in instead of two.

Hey Everyone,      I recently purchased a T420 with Dock Model 4338 and am trying to connect two external monitors.  I want to have my desktop visible on my primary monitor with laptop closed and that desktop extended onto my second external monitors.  Both external monitors are Dell 19", one is being ran through the VGA port on the dock and the other is a VGA cord that I put a VGA to DVI-D adapter on to run off of one of the DVI Ports on the dock.  I can get my desktop to display on the main external monitor, and everything detects the other monitor fine, but the extended monitor remains black.  The screen is on, and recognized as the button light on the monitor is green not yellow and i can scroll my mouse over to that window and i lose the mouse so it's extending just not visible.  I have made sure that both monitors work by checking each individually in the VGA port and they are operational, but the DVI-D port doesn't seem to work on my second monitor.       I have done some pretty extensive searching and can't seem to get this to work.  At my job I have a T430 with the same dock and dual monitor setup that took no time and works great.  Does the T420 just not support this? All help is appreciated.Thank you all,NickG

Answer:Thinkpad T420 with Dock 4338 Dual External Monitors won't work

DVI-D don't support passive dvi to VGA adapter. You are better off with a displayport to VGA adapter, as they are cheaper then a dvi-d to VGA converter.

Hi to all, I have a new chalange  I have aquired a brand new thinkpad Yoga and onlelink dock, is was the first time I bought Lenovo and I'm reaally very disapointed. So far each day a new problem, since the cursor when connect to an external monitor move alone, etc.. My biggest problem so far is the onelink dock, when connect the laptop is always detecting the hardware in the dock, making that each 30 seconds you have a network card, then dont.....or the usb devices, etc...... I really appreciate some help on this, does someone also have this problem ? I have tried do update all software and drivers from the PC and dock, and still no sucess, does the solution pass by aquiring a HP or Toshiba ??????

Answer:Thinkpad Yoga with Onelink Dock

I have the Onelink (basic) dock, and problems seem to be related to the ASIX AX88179 embedded USB3 to Ethernet controller. The System can't start the hardware then constantly tries to restart the driver.The USB2 version of this hardware (ASIX AX88178) works fine with the TPY as a dongle I had laying around.I bet it is a crappy driver from ASIX that is the root of many problems.So, try disabling the Ethernet controller in Device Manager and see if that helps.Don't know, I'm trying to return my dock to B&H right now.So, what is the embedded hardware in the PRO?Deleting the driver for the USB2 version doesn't help either.

Hello. I would like to resolve my problem with my E540 with OneLink Dock Pro.  When dock is connected to my notebook and I press power button, backlight of display lights up, but display stays black, no lenovo logo, nothing... Sometimes it shows logo but it freezes on this logo too. When I disconnect dock, notebook boots up normally. I tryed to disconnect monitor, keyboard and mouse from dock too, but it has no effect. This "freezing" seems to be happening only when dock is connected. On charger notebook boots up normally. And last note, this is happening only on "cold" start, restart works normaly. Problems started just after flashing new firmware to dock (v. 2.30) and BIOS update (v. 2.23). I do not know what made this problems, because I was doing these updates together. Thanks for any answer...

I have a Thinkpad OneLink Pro Dock (DU9033S1 with firmware version 2.21.000) connected to a Lenovo X1 Carbon laptop running Windows 7 (ThinkPad OneLink Pro Dock Driver version 1.08.29). To the DP++ output of the docking station have I connected a Kramer DP to HDMI adapter and a homemade breakout cable (so I can connect to the DDC lines, HPD, DDC 5V power and CEC) to a Benq G2400W monitor. To the DDC-lines on the breakout cable have I connected a Total Phase Beagle I2C analyzer. As you can see from the I2C data I have captured and copied to the next post, are there several issues with this docking related to "High-Definition Multimedia Interface Specification Version 1.3a" chapter 8.5. I have not analyzed the DVI-output, but you should probably verify that it works according to the spec as well. The HDMI output on the laptop seems to work fine. I hope you can forward this to the developers who are responsible for the firmware on the docking so they can fix it. Please tell me when you have a new firmware version where this is fixed! Regards,Mats Randgaard

To Whom It May Concern, This has been a nightmare trying to get support for a 3-year Worldwide Warranty product that my company purchased a little over 1 year ago. The dock's DisplayPort seem to not be working properly. The monitor that is connected to it will randomly go blank. I've tried updating to the latest drivers and firmware for the dock. I tried switching monitors and switching cables. I've tried moving around USB devices to make sure it isn't interfering with operation. I've tried connecting the bare minimum to the devices and the problem persisted. I need the DisplayPort as I am running a dual monitor setup. I contacted the Customer Service line to get support. To my dismay, I was told my product was not under warranty and had to send in a copy of the invoice for my product. The support rep gave me an email address to their entitlement department and was told I will receive a response within 24-48 hours. It's been 96 hours now and no response. I try calling again to check on my status, but told the same thing and that they don't have the service case in their system. I hope some Lenovo rep can see this and provide some assistance.

Hi, I have a ThinkPad Edge E531 that I am experiencing issues with whilst the OneLink docking station is plugged in.- the laptop will not wake from sleep mode. Hibernation seems to work better, but waking the computer from sleep the screen goes black and the computer is stuck in some weird idle mode where nothing happens- when booting the computer the above happens, the computer is stuck idling and won't boot up properly until I force shut down and unplug the docking station- sometimes when booting the computer the OneLink docking station will not be found. I have to either a) unplug and plug in until it works or b) restart the computer and hope it works Is anyone else experiencing the same issues?I am running the computer on Windows 10. TL;DRNon-functioning booting/waking up from sleep whilst OneLink is plugged in, and sometimes OneLink not recognized at all.

Answer:Thinkpad S1 Yoga + OneLink Pro Dock issues

I can confirm that Dell Display Manager is not good with my config also - OneLink (basic) connected to Dell U2412M via DVI.  Can't tell the difference compared to direct connection to laptop though (don't have miniHDMI adapter). @SFsix, sorry about this offtopic question, but do you have any problems with random disconnection/connection of OneLink Pro from TPY, more specifically for Ethernet and USB interfaces. More details here: http://forums.lenovo.com/t5/Options-Accessories/Re-OneLink-network-port-flapping/td-p/1358947 it's a pretty long thread already but in brief all users of OneLink basic non-Pro (myself included) report this problem for constant disconnect and re-connect of OneLink interface. So we were wondering if OneLink Pro users experience this problem... Will appreciate your feedback.

Answer:Thinkpad Yoga S1 failing to charge on OneLink Dock

I believe it is not the OneLink Dock. I believe it is the Battery Maintenance Setting on your laptop.  See:http://forums.lenovo.com/t5/W-Series-ThinkPad-Laptops/ThinkPad-W530-gets-quot-Plugged-in-but-not-cha... This explains that the battery should not remain 100% charged plugged-in over the long term (as would occur with the OneLink or the power cable using your laptop like a desktop). Go to Power Manager and the Battery tab  andBattery Maintenance. If your battery maintenance setting is "optimized," it will not begin to recharge until it is below 50%. You can set it to recharge before that. The link above says that the Battery maintenance is under Advanced settings but mine was under Basic.I have a OneLink and mine is doing the same thing. it also does it with the power cable alone. I have only had my E540 for a few days. I will post again if it does not re-charge below 46-50%.

Hi there, I have an E450 with Windows 7 64-bit Professional, Enabled and Activated TPM on the BIOS, Enabled BitLocker and waited for encryption to complete.  Few restarts and all working fine. I have installed the latest drivers and firmware for the OneLink Pro, as of today 8/20/2015, from the support website. When I connect the OneLink Pro all works fine, NIC, Video, USB, but then when I restart the machine BitLocker kicks in asking for the Password as if the hardware had changed.  Once enter the password it boots into Windows fine but after each restart it will ask again.  Until you disconnect the docking station then following restart is ok no prompt. I've tried some recommendations like suspending and resuming BitLocker while the docking station is connected and it works, after a restart no prompt for password, but when you disconnect the docking and restart it prompt for the password again and again until you connect the docking or suspend/resume bitlocker. Now, I have an exact configuration with a X1 Carbon 3rd generation, doing exactly the same steps and at the end with the OneLink Pro connected or not when restarting it does not prompt for BitLocker password. Finally, we tested the E450 with the older USB 3.0 DOCK and it worked just fine, connected/restart no BitLocker, disconnected/restart no BitLocker. I was on the phone with Lenovo support for 1 hour and 30 minutes, they kept transfering me from the Hardware dept to...

Hello again! Addition: It seems to work with a 19" Hanns.G HW191 screen. Even on higher resolutions (1440x900) used than with the 24" BenQ (tried pretty much every resolution possible), so maybe it's just compatibility with the screen or maximum possible screen size?

Answer:X1 Carbon 20A7 not charging using 90W thinkpad onelink pro dock

wait doesent' the docking station come with own power supply? if so then use that and not the laptop one since i'm quite sure it comes with own AC adapter so it can handle charge of laptop and powering the dock.

Hi all, I'd like to share my bad experience with Lenovo. I bought two months ago in USA a Thinkpad Yoga and an Onelink Pro Dock. I brought it to Brazil and began to use with minor problems - my external monitor used to flash sometimes, going dark and returning after few seconds. Then I updated the firmware and since then I could never more use an external monitor with the dock. Even though it has an international guarantee, the Brazilian support says they cannot validate my dock and fix it, so it is useless. U$ 180 threw in the garbage. Yesterday a vertical black line appeared in my LCD.  I called the support again and they schedule a visit of a technician to change my LCD. I said I want a new computer, since I bought a brand new expensive computer, and don?t want a refurbished computer two months later. I don?t know how it would be if I was in US, but it look like here in Brazil Lenovo support doesn?t care a lot with their customer. I am very regret for buying a Lenovo. Spent almost U$ 200 in a dock that doesn?t work and U$ 1400 in a brand new computer that will be refurbished two months later. I just bought the Thinkpad because had read it is a reliable and durable notebook, but seems it is not definitely the case. Keep using my 5 years old Sony Vaio and holding papers with my new Lenovo. That?s a shame.

Hello! I've just got new ThinkPad OneLink Pro Dock station and connected it to my monitors (2 x ViewSonic VA2246M-LED 22"): first via DisplayPort to DVI cable;second via DVI to DVI cable;The one connected via DisplayPort works well. Another one connected via DVI-DVI cable doesn't get any signal from Dock Station.Even if I unplug DisplayPort cable, the second monitor is still black. My laptop is Lenovo ThinkPad X1 Carbon 3rd. I've updated Dock Station's firmware to the latest one from Lenovo website and I did the same for Intel Graphics driver.Still nothing.

Hello everyone,  I would like to connect 3 external monitors to Yoga 260. I found out that conection of 3 external displays is feasible. It is associated with turning off the native LCD, whcich is OK for me. I would like to use ThinkPad OneLink+ Dock (40A40090XX). The docking station has 2 DP and 1 VGA. The issue is I'd rather use 2 DP from docking station and one DP which is on board Yoga instead of VGA. Is such configuration possible? I would like to figure it out before I will buy the station. I've found document: https://support.lenovo.com/uu/en/documents/pd029622 , but there is nothing on using docking stations' DP and native DP in one configuration, simultaneously. Whether it is because on board DP will be disabled? The alternative is MST (eg. http://www.club-3d.com/index.php/products/reader.en/product/multi-stream-transport-mst-hub.html). Both devices are at a comparable price, and if I had confidence that the docking station will work with onboard DP simultaneously, I would choose it.  Thank you in advance, best regardsM

Answer:Yoga 260 + ThinkPad OneLink+ Dock = 3 working Disp...

Since no one has replied, I would like close this discussion.  Still someone might benefit for the information, that: - I have purchased and tested ThinkPad OneLink+ Dock- it works with 3 external monitors using 2 DP from docking station and one mini-DP from Yoga itself- working configuration is as follows: 2 displays are connected to OneLink+ Dock with one active DP to DVI converter, one passive DP to DVI converter and the last one (Yogas? port) with active mini-DP to DVI converter- I didn?t try to use for example 2 or 3 passive DP to DVI converters (but I guess that 2 should do the job, but 3 will probably won?t work)- when OneLink+ Dock is attached, the HDMI port in Yoga is not working! (the information one can also find in BIOS, but no materials on-line) Best regards,Maciej

Hello fellow users / Lenovo, In our office we have several X1 Carbons and several ThinkPad USB 3.0 Docks (0A33970) located all over the office. We typically bring our X1 Carbons around and use each other's Dock during the course of work. However, we recently face a problem with the Ethernet interface not working with other Docks, other than the Dock that the driver was installed with. Using other Docks, the Ethernet interface comes up as a generic Ethernet device with a yellow warning triangle inside Control Panel. Using the Dock that the driver was installed with, the Ethernet device works as normal. It should be pretty easy to replicate this behaviour, just get an X1 Carbon (fresh, Windows 8.1) and connect a USB 3.0 Dock to it, and install appropriate drivers.Verify that the Ethernet port works correctly. Next, disconnect the Dock and connect another Dock to the X1 Carbon. Observe that the Ethernet interface does not work, and see the yellow warning triangle icon under Control Panel. Uninstalling and Reinstalling the drivers with the new Dock doesn't work either. Only the Dock that the driver was originally installed with will work.

Hi, I have stuggled at lot with getting new 27" Dell 16/10 screen to work with my OneLink Dock. After finding out the DVI-1 connector was the limiting the resolution by connecting the screen using HDMI directly to the Yoya it worked perfectly. ProblemNow i'm trying to put the OneLink Dock back in the loop so i only need to connect the one cable when docking. I tried to connect using a Display port cable since the dock doesnt have HDMI. And nothing happens. The screen is not getting a signal from the dock. It is a brand new cable baught for this one cause, and the screen port works. Is it a driver issue, or is there something i can do to solve this issue and get my all Lenovo setup working in the office. /RegardsHenrik

My Onelink Plus dock behaves very strangely, I cannot use the Ethernet port reliably:I bought recently a Thinkpad Yoga 460 ? after my previous Thinkpad ? and an Onelink plus dock. After docking I have to disconnect and reconnect all cables from/to the dock to make the Ethernet work.After that it works great for a period, but sometimes it loses the connection. I have to unplug again all the cables and reconnect them to make it work. To the dock I attached the following: USB keyboard, mouse, external drive, DisplayPort cable (with DP to DVI adapter) and the Ethernet cable. I am using Windows 10 Pro 64 bit (ver. 1607) from a clean install. Every device in the Device Manager seems to be OK, even the ThinkPad OneLink Plus Dock Ethernet.I have the latest software and firmware.Lenovo Companion cannot find new updatesI have updated the BIOS to ver 1.46.I have also updated the Onelink plus dock firmware (Version: 2.33.000). Any idea? This way the dock is useless.

Dear all,

I just received my new Thinkpad X1 Yoga, brand new, with a dock OneLink+

Both are running fine. But it is impossible to start the PC when the dock is connected: The screen freeze at the red square LENOVO display from the Bios, windows 10 pro doesn't start.

I have to disconnect the dock, et relaunch the PC to enable a normal start. After the start, I can reconnect the dock.

I updated all drivers, flashed the bios, latest FW of the dock and even resetted Windows, but without success.

Lenovo support wants to change the laptop (!), it's brand new!

I thought maybe one of the topgun member of this community might have a better idea.

Thanks in advance for any advice.

When a Windows 8 ThinkPad Yoga is connected to a ThinkPad OneLink Pro Dock (Model DU9033S1) which has a sound cable placed into its headphone jack, every few seconds the sound will alternate between the laptop speakers and the docking station. It appears that the connection to the docking station is briefly lost (sound comes from laptop speakers), and then re-established (sound goes to docking station). However, during this "disconnect/connect", all other aspects of the docking station are unaffected (video, network, USB).
 
Updating BIOS, audio drivers, dock drivers & firmware have had no impact. If sound cable is removed from dock, then behaves normally (sound goes to dock only). Happens with multiple Thinkpad Yogas and multiple docking stations.

The newest OnLink Dock Pro drivers and firmware is also installed. When the OnLink Dock is attached to the notebook and a network cable is connected to the Docks LAN-port the notebook hangs at the "Lenovo"-screen during boot.When booting with the attached Dock but without the network-cable connected, the Notebook boots normally. "Secure Boot" and "Lock Boot Sequence" is enabled in BIOS, also the LAN-Port is removed form Boot-Priority list. The notebook hangs right after the BIOS is finished and short before the Windows loading animation should appear.The Windows Startup logging doesn't help either, since it hangs before a logfile is even created. Anyone having an idea what is wrong?

I recently purchased a ThinkPad Yoga with a OneLink Dock Pro. I am having one issue. When I plug the laptop into the one link I get a constant device disconnect sound over and over until I reboot. This happens most frequently when the device goes into sleep mode NOT attached to the dock and I then attach the device to the dock and wake the device up. It happens in other scenarios too but this scenario causes it almost 100% of the time. It is extremely annoying.  In addition, this scenario also causes my HDMI sound (through my Asus monitor) to not work and switching play devices in Windows 8.1 doesn't work until I reboot. Once I reboot, the annoying sound goes away and my sound devices all work. There seems to be a few one-off scenarios that cause this to happen as well but none I can pinpoint just yet. Has anyone else encountered this and is there a fix?

Answer:Issues with ThinkPad Yoga and OneLink Dock Pro - device constantly "disconnects"

Unfortunately, you are not alone.  The combination TPY with OneLink and OneLink Pro is not (yet?) a stable marriage. See, for example, this very long discussion thread (22 pages, >210 posts, 3 months, and counting...):http://forums.lenovo.com/t5/Options-Accessories/Re-OneLink-network-port-flapping/td-p/1358947 Lenovo has still (after 3 months!!) not provided a fix for this issue. In the above thread some workarounds have been posted, which seem to work for some. See Page 15 and page 22, for example. Lenovo is really dropping the ball on this one.

I'm having a few issues with a t440s + 135w Ultra Dock. I've updated the dock's firmware and it works fine with my two external monitors. I have one problem that is driving me crazy. When I put the machine to sleep I can't wake it up with my mouse or keyboard. If I plug the mouse and keyboard directly into the machine they will wake it correctly but in the dock, it's no go. The other problem is once I actually bring the machine back from sleep it has to re-initialize all of the usb devices on the dock, like they've been completely unplugged. This second problem wastes a lot of time, right now I have the wireless usb mouse plugged directly into the machine so I can wake up with the mouse but my usb keyboard takes about 10 seconds to re-initialize, so I am stuck waiting at the lock screen for that long. I've turned on the USB when sleeping and the charge USB while sleeping in the BIOS - didn't help. Also made sure that all the devices could wake the machine up in the Device Manager. One other "issue" that is only mildy annoying is anytime Windows shows my a UAC prompt the screen goes black and takes about 5 seconds to render but only on the monitors attached to the dock. I'm running windows 7 pro 64 if that helps at all.

I have just rolled out 3 x ThinkPad T440s laptops with Ultra Docks running 2 x 24" monitors via DisplayPort connected to them.  These are the first 40-series ThinkPads I have implemented, and these are also our first systems running Windows 8/8.1; everything else runs Windows 7.  We run Windows Enterprise, so the laptops have a clean image installed by me. THE ISSUE:The laptops work great on their own.  The experience with the Ultra Docks is far from perfect right now though.  On all three PCs, shutting down or restarting the PC while docked causes the computer to either hang at a black screen or get stuck when the Lenovo logo: the little circle balls to indicate Windows is loading never come up.  The only fix for this is to hold down power to shut off the laptop, and then undock and redock the laptop.  It is ridiculous a computer cannot restart successfully on the dock.  I assume firmware can fix this? I also have an issue with our existing Bluetooth keyboards and mice not being recognized all the time on startup - most of the time we have to manually reconnect them on boot.  However, at this point I think that is a Windows 8.1 or Logitech problem. Other than that, quite happy with the ThinkPad T440s (and Windows 8.1).

Answer:ThinkPad T440s + Ultra Dock problems

FURTHER ISSUE:I think others have reported similar issues to this with the new docks and 40-series ThinkPads... We use Dell UltraSharp U2412M monitors which are 1920x1200 resolution.  All the monitors are connected by DisplayPort and are detected as being Dell monitors by Windows. One of the ThinkPad T440s' went to sleep on the dock while the user was at lunch.  The user returned from lunch and woke it up.  One of the monitors was detected as a "Generic Plug and Play" monitor and was set to 800x600 resolution.  It was not possible to set the resolution back to 1920x1200, but a restart fixed the issue. A POSSIBLE FURTHER ISSUE:This same laptop successfully restarted on the dock.  But upon logging into Windows 8.1 Enterprise, the local network shares failed to load, suggesting a network connectivity issue.  Not sure if this is dock-related or not, or if it is just a Windows 8.1 Enterprise issue.

Hi, Yesterday I upgraded from Windows 8.1 to Windows 10 Enterprise. After the inital install I had both monitors (HP ZR30w) working for a few minutes. Suddenly both monitors went in sleep mode and I'm unable to get them working. They are connected via 2 DP cables to a Ultra Dock station. Only way to get a signal (one at at time ) is to use a DP to mini-DP adapter and plug it directly to the computer. I can see that the computer is charging while docked, so there is some sort of connection there. I've searched all over the net for any drivers for the monitors, Ultra Dock and T440s which looks like can fix the the signal issue. No luck. Anyone else experienced this issue? Regards, hetterotte

Answer:T440s + ThinkPad Ultra Dock after upgrade to Windows 10 - no signal

Hi, I'm having the exact same problem with Lenovo X250. I have HP ZR30W and Lenovo Ultra Dock which is connected via displayport to my monitor. With Windows 10 there is no signal at all for me from the dock. But if I connect my laptop directly (without dock) via a mini-displayport-to-displayport adapter the monitor works. I have tried all the latest drivers (and latest firmware for the dock) with no success. I had to revert back to Windows 7 since the dock DOES NOT work with Windows 10!
