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!

I am just going to guess that computer is trying to boot via USB, so you might try changing the boot order in the BIOS so that Windows Boot Manager or the HD is first.

I can't figure out how to make this work.I also tried this setup:Monitor 1 - laptop screen - works.Monitor 2 - VGA out to VGA in - worksMonitor 3 - HDMI out to HDMI in - worksMonitor 4 - DP out to HDMI in via a DP-HDMI cable.  - doesn't work. Incidentally in this configuration, when I closed the laptop screen this monitor worked.  Also on a related note, the Nvidia Quadro P500  is sitting idle as the Intel UHD 620 is doing all the work.  How can I control this? Thanks for any suggestions. Sal

A:Thinkpad P52S Ultra Dock and 3 External Monitors

As stayed in PSREF, P52s supports up to three independent displays. Laptop's screen includes in this limit, meaning you can use two external displays at that time. When you close the lid, you can use three external displays. To use more, you'll need some sort of USB adapter to increase such a limit. Regarding other question, you can't disable Intel GPU - it's always active and it's always controls screen output. NVIDIA's dGPU can be configured to be used in selected applications, making them to work with higher performance. P52 and P72 for sure have an ability to disable Intel iGPU, giving the control of screen output to dGPU. Probably P1 and/or X1 Extreme have the same feature too.

Hi,  I'm using a Lenovo P51 with M2200 graphic card and have a docking station 40A2. I wish to connect the two monitors to my docking station, one is VGA cable and another one is HDMI. When I dock my P51 to the docking station, the monitors could not be detected. I tried to configured my bios setting to discrete graphic setting but nothing changed. Try to put shared on dock display also but nothing works.  When I connected one of the monitor HDMI cable to the laptop directly without going through the docking station, it works perfectly but I could not connect the VGA cable monitor to the laptop without a converter and it defeat the purpose of having a docking station.  Anyone encounter this problem and has a solution for this problem?

Hello, I recently bought the Ultra Dock 90 for my T450s.  I have one external monitor currently connected through the dock.  When I push the power button on the docking station (laptop lid closed) to turn on the computer, the computer turns on, but the external monitor does not engage.  When I lift the laptop lid, there is no image on the laptop screen either.  The laptop is on, but does not respond to any key stokes on the actual laptop.  I then have to do a hard reboot using the power button on the laptop. If I initially power the laptop by lifting the lid and hitting the laptop power button, the compter boots and my external screen works.  I can then close the laptop lid and everything is fine. I know the power button on the dock should power the computer and external monitor on.  I am guessing there is a simple solution to resolve this, but I am not a computer person and need help. One thing to note - when I lift the lid after trying to power the laptop through the dock, I see that the Function Green Light is illuminated.  Not sure if this information is helpful in determining the problem. Please help! Peterrabbit33

 When I connect my Thinkpad P50 to my external monitor (Samsung C34F741) directly using the mini Diplayport (connector on the side of the laptop) everything works fine. The resolution 3440x1440 @ 100 Hz and sound on the monitor speakers all work flawlessly. However, when I connect the same external monitor to the Displayport of the Lenovo Workstation Dock (using the same cable), the video works fine (same resolution and refresh rate as above), but the audio on the monitor speakers lags behind the video. The lag is at first barely noticable but increases as time passes, eventually getting out of sync a few seconds. I have the latest nVidia drivers and the latest Workstation Dock firmware installed. I am suspecting the external Displayport on the docking station is not capable of driving the high resolution at such a high refresh rate. Is there indeed a difference is specs between the laptop's Diplayport and the Docking station's Displayport? Can anyone offer any suggestions? Thanks.

Hi,one of the guys at my workplace uses two displays with his X250 and Pro Dock. One of them is an LCD 1080p connected through DP and the second one was an ancient display with 1440x900p panel connected through VGA. Week ago or so the VGA display started flickering, and is unusable for work since it hurts your eyes after a while.I have tried every solution that was either recommended on the internet or I thought of, yet the problems persist.Until now, I have tried changing the cable, display, Pro Dock, none of that worked. I also tried installing latest firmware from Lenovo Update for the Dock and latest BIOS. I even reinstalled Intel HD Graphics driver, along with some other drivers from Lenovo support page.The display works properly when connected directly to the notebook, only in the dock it starts flickering. Is there anyone that had similiar problem and knows how to fix it?

I have a W541 and it always worked well with the dock and dual external monitors, that is until the firmware was updated by Lenovo System Update to the Latest Version: 2.33.000 about a week ago. Now when you boot the laptop in the dock, the post shows on the two external monitors then they go black and seem to disconnect as the power saving icon shows on both monitors. If you undock the laptop at this point and immediately re-dock, the two monitors light up and no more issues. While this isnt a huge issue, it is very annoying since it always worked properly before the update. Any suggestions on a possible fix are much appreciated. Thanks in advance.

Yesterday, I updated my T450s and, among other updates,I updated the Ultra Dock 90W firmare to version 2.29.00.  Afterward, when the laptop is docked, with the cover shut, and I try to power up the unit, it won't do so.  When I open the laptop in the dock, the power indicator is green and there is a green light on the function key.  No matter what I try, the machine won't power up after this.  If I force it to shut down and then try to power it up open instead, it powers up normally and both the laptop screen and the attached monitor work and, if I close the cover after, the attached monitor still works.  Obviously, I can use the machine docked with this work around, but I can't figure out why it won't work when I try to poweer it up closed.  I subsequently updated to version 2.30.00 and the behavior continues. What am I missing here?

I spent a day working on an issue and want to share to save folks time.  Bottom line, Intel Graphics Drivers WDDM 1.0, 1.1., 1.2, 1.3 automatically updated with Windows and broke the system. BIOS and Lenovo splash screen showed and safe mode worked fine showing this was not a hardware issue.  Windows began to load and the screen went black.  I connected an external monitor via HDMI, pressed power for 2 seconds to put the machine to sleep, pressed power again for 2 seconds and it woke up on the 2nd monitor. In Device Manager, the 2nd (HP w2007) monitor showed up and there was no mention of the laptop physically connected display. I reinstalled Windows 10 and all was well until the auto-update occurred and I had the same issue.I installed Windows 7 and all was well until I installed all updates, same issue. I didn't think this was a display adapter problem because the 2nd monitor worked just fine and it was the monitor that didn't show in Device Manager.  Alas, my assumption was incorrect. After HOURS of selecting which Windows 7 updates to install, nearly 180, I finally narrowed it down.  I thought it was a Windows problem, turns out this was an Intel Graphics driver issue. SOLUTION: I used Revo Uninstaller to remove the Intel Graphics driver program and the system recovers.  Sadly, in both Windows 10 and WIndows 7, the auto updates would put the drivers back and the same problem recurred.  I was finall...

The only way to make contact, is to withdraw the HDMI connector and reconnect.Have the latest updates on my Lenovo Thinkpad L560.Please help. Now using Packard Bell and Ubuntu without this problem.

Hi,After updating to the JBET67WW 1.31 BIOS my mouse and trackpad cannot click on most UI elements in Windows 10 (1709) when connected to a ThinkPad Ultra Dock (40A2), some still works like minimize/maximize and close buttons on windows but most dont. I've tried to force a re-apply of the update but it is still having the same problem. Previously I used 1.30 without any problem, so the question is where can I get the files for 1.30 to do a downgrade?

Hiis there a benefit of the ultra dock 170w for L570?https://s3.amazonaws.com/isby/lenovopartnernetwork.com/upload/4/docs/presentation-thinkpad-docking-s... I?m interested in 3 things -  1) I want external display digital UHD @ 60Hz & analog FullHD @ 60Hzthe dock offers that, and no more at 60Hz, and to my understanding disables the built in laptop graphics ports, which also offer that - so what?s the benefit? 2) I want good amperage on usb 3.0 ports - does the 170w dock offer more power via USB than built-in laptop ones? 3) Does it disable the built-in USB? Thanks!

I'm using a Lenovo Thinkpad Ultra usb 3.0 dock (40A8) with two 1080p monitors (HDMI + DisplayPort). Using the display on the laptop as my third monitor. I have my USB mouse and keyboard plugged into the dock as well as headphones and gigabit ethernet. I also have a second gigabit ethernet dongle plugged into one of the usb ports on the dock. The dock is paired to my Thinkpad P52 workstation. My issue is that while I'm working my display will freeze (mouse, keyboard still responsive on laptop monitor). Then I'll hear the USB disconnect sound, my screens will go black, then they'll come back a few seconds later as if everything is normal. My network connection drops momentarily as well. At first this was just annoying but I've recently moved over to a soft phone and now this causes big problems. When the dock 'restarts' I lose my audio connection to the phone and the brief network connection drop causes my call to drop. I've tried all the basic stuff such as updating the DisplayLink drivers to the latest, turning off USB selective suspend in power settings, using a different usb port. Is this problem specific to my dock or is anybody else experiencing this issue?

I have ThinkVision monitors connected via VGA and the display port. I have a 4k TV connected to the DVI on the back of the docking station. I am able to extend my desktop on the two ThinkVision monitors but I am not able to detect the TV to use for my third.
