How to undock/dock to USB 3.0 Dock so extended displays are recognized on reconnection

I have an X1 Carbon connected to a ThinkPad USB 3.0 Dock. I extend the display to use a desktop monitor. When I undock the laptop from the dock (i.e. remove the USB 3.0 cable) work undocked and then reconnect, I cannot access the display I have connected to the USB dock. The mouse and keyboard that are connected to the dock work OK.
Trying to Detect in the Lenovo DisplayLink manager doesn't find the monitor.
Is there a way to "undock" so that the display is recognized on reconnection? e.g. switch off the USB 3.0 dock before removing the USB 3 cable?

Yes - did you ever find a solution? I tried updating the Displaylink driver.

Drivers for USB 3.0 Dock

Recently purchased X1 Carbon. Wiped drive and installed Windows 7 64-bit from existing image/clone. Connected USB 3.0 dock to laptop and installed all applicable drivers through both Windows Updates and the Lenovo System Update utility. As it stands, I have no ethernet connectivity through the dock even though the dock is recognized by the computer and the network activity lights (green and orange) are working on the back of the dock.
Currently all drivers are installed except:
- Lenovo USB Ethernet
- ThinkPad USB 3.0 Dock
- ThinkPad USB 3.0 Dock
Additionally, the Lenovo USB Audio shows, "This device cannot start." Presumably, this affects the head phone port of the dock.
What am I missing? No installation disk was included with the dock but I believe the Lenovo System Update utility should have taken care of that. Any suggestions would be appreciated.

For those who care, here is a link to the appropriate drivers. I find it disheartening that the Lenovo Software Update utility found drivers for everything else but this. Anyway, here is the link: http://support.lenovo.com/en_US/product-and-parts/detail.page?&DocID=PD023761

Wake from sleep when docked to Mini Dock using USB mouse or keyboard attached to dock

I'd like to know how to wake a T520 connected to Mini Dock (type 4338). I have a basic USB mouse (wired) connected directly to the dock. I've verified all of the items in Device Manager (mice and USB ports) are enabled for "waking the computer".
In the article below, Lenovo says it's not possible to wake it by connecting directly to the dock....they say it's "not a limitation of the dock"... but "by design". Of, course that's the line all companies say now a days. But it CLEARLY IS A LIMITATION. They say the only way is using the power button on the dock. What a waste.

Thinkpad X1 Mouse Issues with USB 3.0 Dock and WIndows 8.1

I have a new X1 (3444-CUU) that I recently upgraded to Windows 8.1. When I connected to the Thinkpad USB 3.0 Dock, there was an automatic updated of the firmware on the docking station.
Everything seems to be working except issues with my Keyboard and Mouse.Periodically, the mouse will disappear of the keyboard will simply stop working. Most recently, it was as if the delete key was stuck causing it to delete all my email (actually a feature I liked but unfortunately, can't allow).
Is there a known issue with wireless keyboard?

I have a possibly similar issue that seems to be related to the keyboard dock. In my case this is with logitec unified receiver, but what I found may help you narrow the issue's root cause.
I found that after a reboot, the dock's USB ports (bothh SS or USB 3.0) will not recognize logitech's unified receiver. Even though it is Windows reporting it, it seems to be related to the hardware. What I do to have minimally invasive 'functioning' system is to undock the Helix (use as tablet). This makes the genuine USB 2.0 port of the tablet accessible. I then plug the receiver into that port and wait until the mouse is recognized. Then remove the receiver, re-dock the tablet on the keyboard dock and plug the receiver into the dock's usb 3.0 port. Then everything works.
That seems to somehow circumvent part of the refreshing of the USB connected devices and allows them to work correctly.
I wonder if that addresses your issue. Of course I am opening another thread and ticket with that issue (will post a link after that)

ThinkPad USB 3.0 Dock - Firmware update doesn't work

Hello,
My company has bought over 200 ThinkPad USB 3.0 Docks to use with HP Folios to connect dual and single monitors. Some users have experience multiple issues with this product and I am trying to determine how to resolve these issues. I first want to update the firmware that is located here: http://support.lenovo.com/en_US/guides-and-manuals/detail.page?DocID=UM014961
ThinkPad USB 3.0 Dock - Firmware Update - Lenovo Docking FW Update Tool V1.0
I have the USB 3.0 dock connected to the 3.0 USB port on the Folio. The unit I am testing seems to be working fine as I have dual monitors up, external keyboard and mouse are working.
I ran the .exe, a command window comes up, and it attempted to look for the device. The text is as shown:
1. Initialzation<> Success
Start Search HUB
!!!No device found!
Press any key to continue . . .
This has been tried on several devices and it simply does not work. Does anybody have any suggestions? I have contacted support which was a complete waste of time because they have no idea what I am talking about.

I'm going to return my dock if possible. My main problem is that I cannot view Vmware virtual machine which is required for work. 2nd I can't view photos on my dual screens, it just hangs saying "Loading...", but I can view them on my W520 LCD Display. 3rd, I can't view a downloaded video, as in an .mp4. I disabled the hardware acceleration in Firefox, so I can see streaming video.
I have a Thinkpad W520 and an X1 Carbon and both exhibit the same problems with the dock.
I tried upgrading the DisplayLink Drivers to the 7.x version and that created a slew of problems. The Dock firmware driver link in the OP doesn't work either. As mentioned it couldn't find the device. Uninstalling the drivers and reinstalling the stock one cause lots of problems with my W520. The dock would try to connect but it kept connecting and disconnecting and the cycle would continue infinitly. It wasn't until I did a system restore that I could get it working again to where I can use the dock again.
I am extremely dissapointed with this dock.

Recommendations for external monitor in combination with USB 3.0 dock and X1 carbon touch

Dear Community,
I'm waiting for my X1 carbon touch and USB 3.0 dock and keyboard/mouse to arrive any time soon. However, I'd be glad to get some help/recommendations on external monitor choice.
For instance, the new HP envy 27" caught my eye, since it includes speakers, but it comes with HDMI and Displayport connections only. As far as I understood, video connection itselft shouldn't be a problem using a DVI to HDMI adaptor, but how about the resolution of the X1 vs. a HD+ monitor, and how do I use the audio on this monitor (don't want to use the microphone jack in front of the dock, as it should look as minimalistic as possible)?
Is there a solution? via usb 3.0? or should I better consider another monitor? Anyways, DVI or HDMI, I don't want to connect a separate audio system to the dock. Any recommendations, or is it one of those gadgets that has not been thought through well enough and you need to wait for the next generation to be developed?
Many thanks for your help,
Cheers, jcd

Since you don't want to use the jack on the dock, you could usethemini-DisplayPortontheX1cTouchasyourvideooutputoption because the version of DP on the X1c Touch includes the ability for audio to streamed over the DP connection in addition to video. This would require a compatible DP monitor.
You'll also want the monitor to support audio over the DP connection. The X1c Touch's graphics supports the output of an audio stream over DP and the machine should be be capable of this. This gives you two cables connecting to the X1c Touch -- the DP cable for audio and video and the USB 3.0 cable connecting to the dock. The dock would be attached to keyboard, mouse, USB accessories, and Ethernet (if necessary).
As far as what to look for in a monitor, my general recommendation is Dell Ultrasharp. They tend to be a good deal for an IPS monitor with at least an sRGB gamut and a solid warranty. I've never bothered to attempt to stream audio over DP because I have separate speakers for audio. In the same way that my last 3 laptops have been ThinkPads, my last three monitors have been Dell Ultrasharps. The graphics in the X1c Touch should be fine running a 1920x1080, so I wouldn't worry about resolution. It can be a little jarring to use monitors side-by-side when they have different pixel densities, so you'll likely end up treating them as separate display surfaces. I often have e-mail and Pandora open on my T420's screen while I'm doing the bulk of my work on my main monitors. If you think you'll be touching the screen a good bit, then you might want to look into buying a touch capable monitor. Otherwise your brain can become easily confused because it'll begin to think that all computer screens are touch-capable and you'll reach out and try to touch your desktop monitor without thinking.

How do you eject a usb device from a mini mac

How do properly eject a USB device from a mac mini?

Ejecting in Mac OS X:

2. Right click and choose "Eject"
3. Click it once and click File>Eject from thre Finder menu
4. Click it once and press Cmd+E
5. If your keyboard has an Eject" key (usually located above the "Delete" (a.k.a backspace) key, you can Eject media from the optical drive with that
ANY files or apps opened or running from the external drive MUST be closed BEFORE you can eject it.

USB 3.0 Dock doesn't recognize dvi-d

USB 3.0 Dock Upgrade

At the beginning of the year I purchased an X1 Carbon Touch with a USB 3.0 Dock. It has taken me a long time to get it configured the way I like it. The USB 3.0 Dock is the last item.
First off this is not what I would consider to be a dock. With the dock for my T400, the lid could be closed. Unless I am missing something, the lid on the X1 Carbon has to be open for this "dock" to work.
Anyway, I was having local network issues. If I copied a large file (> 1GB) to my NAS, the Ethernet would drop out and the network would switch to one of the wi-fi connections.
Last week, I went to www.DisplayLink.com and looked at version 7.2. The comments seemed to fixed some of the issues I was having. I installed the software and the wired network went to crap. Instead of > 20 Mbps on speedtest.net, I was getting 5 Mbps when the connection was up. I had to switch to the wi-fi connection. I uninstalled all the software and installed Lenovo v10705. I am actually in good shape right now.
This brings up lots of questions:
1) I have seen many posts about getting software for the USB 3.0 dock from DisplayLink.com. Should their software be used or not?
2) The Lenovo software I am now running is ver 7.0 (I think). There is ver 7.1 on DisplayLink.com. Does anybody use this version, should I install it?
3) DisplayLink.com says their software is for the DL-3000 family. Is the USB 3.0 dock part of that family?
Thanks for any advice you can give me.

Working for DisplayLink, I would recommend v7.2, as it fixes a number of end user issues that were coming up on previous 7.x versions.
The lid can be closed, but usually the laptop will be configured to go to sleep when the lid is closed. This can be changed in the Windows settings. We have an article on how to do this here.
V7.2 includes a completely new Ethernet driver, which was designed to try and improve speed and reliability. After upgrade it might be worth removing all cables from the dock, power cycling it and replugging, just to make sure it is updated correctly.
We know of an issue that can cause a slow upload speed with some host controllers (ironically we turned on a change to try and improve Ethernet speed, but seems to have problems when used with some PC host controllers) and I wonder if this is the issue you are seeing.
We have a fix for this in our next 7.2 maintenance release which will be available in the next month or so.

USB 3.0 dock question

I have a Thinkpad Edge E530 and recently purchased the Thinkpad USB 3.0 Dock. My question is how do I set this up so I can close the lid of the laptop and continue to work?
I have a USB keyboard, USB mouse, Network cable, the E530 laptop and monitor connected to the Dock. I want to be able to close the lid on the laptop and work with the keyboard, mouse and monitor.
Is this possible? Do I just need to change the sleep settings on the laptop?
Thank you.

Thinkpad USB 3.0 DOCK / Helix / Windows 8.1

I have recently purchased a Thinkpad USB 3.0 Dock for my Lenovo Helix which runs with Windows 8.1. i have installed latest drivers and also latest version of Displaylink which supports Windows 8.1. when ever i plug my external monitor to my Dock, my Intel HD Graphics 4000 display driver crashes and doesnt work again. i cannot reboot after that and it ends up with a BSOD. BSOD shows that there's an issue with dlkmd.sys file. only way for me to recover is to uninstall Thinkpad USB 3.0 Dock drivers (By reverting back to a system restore point).

I have a possibly similar issue that seems to be related to the keyboard dock. In my case this is with logitec unified receiver, but what I found may help you narrow the issue's root cause.
I found that after a reboot, the dock's USB ports (bothh SS or USB 3.0) will not recognize logitech's unified receiver. Even though it is Windows reporting it, it seems to be related to the hardware. What I do to have minimally invasive 'functioning' system is to undock the Helix (use as tablet). This makes the genuine USB 2.0 port of the tablet accessible. I then plug the receiver into that port and wait until the mouse is recognized. Then remove the receiver, re-dock the tablet on the keyboard dock and plug the receiver into the dock's usb 3.0 port. Then everything works.
That seems to somehow circumvent part of the refreshing of the USB connected devices and allows them to work correctly.

W530 with USB 3.0 dock hardware profiles

I have a thinkpad W530 running Windows 8.1 Update that is connected to a USB 3.0 Pro dock when i am at my desk. Is there any way to get the laptop to sense the docked condition and toggle Audio/Video to the external devices and then toggle to the internal devices when undocked? It seems hit or miss on this happening. We use Microsoft Lync and sometimes when i boot up connected to the dock, Lync still is set to use the on laptop camera and speakers. If i set it correctly docked, when i boot up off of the dock, Lync sometimes gets the hardware correct and sometimes doesn't.
I was hoping that there was either a Lenovo utility that could sense the docked vs undocked condition and toggle appropriate hardware or that i have something set wrong that someone might be able to suggest.
Thanks.

Just a quick question: the Mini Dock Plus USB Series 3 with USB- 170W dock (part number 433835U) IS definitely compatible with the W530? I just finished text chatting with a rep (I know, I know) and was told "There is no compatible docking station for the W530). Yet, I found where the W530 is listed as compatible here: http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-4TPJF4
Does anyone have any actual experience with this docking station and know for certain whether it's compatible?
Thanks!
