S540 OneLink Dock Problem - Power but no USB, Network or HDMI ports working

Q: S540 OneLink Dock Problem - Power but no USB, Network or HDMI ports working

I have a ThinkPad S540 with a OneLink Dock (not Pro). It has work fine for several years until today. Power is getting through to the laptop from the dock but none of ports (USB, Network and HDMI) work. Ihave tried to install a new driver however, after installation I get the message:"Unable to execute file:C:\SWTOOLS\DRIVERS\TP_Onelink_Driver_v11019.exeCreateProcess failed code 740.The requested operation requires elevation". It looks to me like the Dock has died but somehow the power supply to the laptop can carry on while the cleve stuff has stopped working. Any help appreciated.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

Hi All, I have a Thinkpad S540 laptop with a OneLink Pro Dock. I want to use the display port to plug a new screen, but it does not work. The docking station seems that cannot detect the new screen. I have tried pluging and unpluging the existing monitor.... but with same result. The monitor is working, so it is something wrong with the docking station or the Displayport.I have updated the Intel Graphics in my laptop, the docking station firmware and drivers and still not working.  Can anybody give me a hand? Perhaps am I missing something?  Many thanks, Juan

Hi. The OneLink+ Dock has a "regular" USB 2.0 port on the back and one with an additional keyboard/mouse symbol. Is there a difference? If yes, if I have an USB keyboard and a USB mouse as well, which one should go to the keyboard/mouse port and which one to the regular one?

Dear all I am using a switched power connector strip for my PC environment devices (monitor, powered speakers, and the like) which is switched by a usb cable plugged into the PC. If the PC is off, there is no power on the usb port, so the connectors are all off which saves some electricity. Up to now I used a Lenovo basic usb 3.0 dock, where this worked flawlessly. Once the pc was switched off the USB power on the dock (at least at some usb sockets) went out. So I could switch the connector strip. I recently bought a OneLink Pro dock (in the meantime, and after a series of annoying problems, everything is up-to-date: Windows 10 drivers, dock firmware, Thinkpad BIOS). But there is one problem left. I first connected the dock to the Thinkpad, with the monitor attached and tried which usb ports would switch off power when the Thinkpad was off. When the PC was shut off only the one usb socket at the front (the one which is not labelled "always on") went off.  All others stayed on. Now it seems that out of a sudden /all/ ports stay on if the Thinkpad is off (completely off, not standby), also the one which was switched in the beginning. Only if the thinkpad is switched on, the usb power goes off for half a second or so and then is switched on again.  This is not what I want; I do not need all usb ports to be "always on", but only the one designed to be at the front of the dock. Is there a way to get the dock's u...

I purchased a new Ideapad S540-14IWL recently but couldn't find a way how to connect a secondary display via HDMI. I use Windows 10 Pro. So far I've tried the following:- using different monitors;- using different HDMI cables;- installing newer and older Intel VGA drivers;- going through the Windows 10 video troubleshooter;- switching off the laptop and/or the monitor and powering them in various sequences (as suggested in a few articles I found on the Internet);- tried to switch to the second display using Win+P, of course. No matter what, Windows is not able to detect a connected display (even after I manually push the 'Detect' button). The display itself finds no signal. Surprisingly, the Lenovo diagnostics utility couldn?t identify a problem after running both the Display and the Display Interface tests. The laptop is flashed with the latest BIOS. I read other Lenovo models have similar issued when AHCI mode is selected in the BIOS rather than RST. However, switching to RST comes with a warning that the controller change will result in all the data being erased, which I can't afford.  Any help on that issue will be appreciated.

We have a few Lenovo displays we are replacing and wanted to get some USB-C displays for our few MacBook Pro users, but also work with our OneLink Pro & Ultra Docks. Ultra Dock works great with DisplayPort & HDMI. The MacBook Pro's work great with USB-C and Apple's USB to ethernet gets us all set there. The issue is the X1 (gen 3) with OneLink Pro dock. When we setup the dock with DisplayPort it shows the display is connected in the Display Properties, along with resolution and extended desktop, but the display itself shows nothing and has an orange light. We tried 3 different docks and laptops, 2 different P24h displays, and 3 different DisplayPort cables. Confirmed both the display and dock support DisplayPort 1.2. Any idea on what I can do to get this going? So far this is the best display we could find that covers all our bases for our needs.

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

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

All, I recently purchased a ThinkPad E531 together with a OneLink dock. The laptop appears to be working just fine. Currently running Windows 8 64 bit. However, the OneLink dock is giving some problems: First of all, the HDMI connection, network interface and USB 3.0 ports seem to be working fine, but... - the audio interface is not working nor is it recognized by Windows (currently I have a simple speakerset connected, but headphones didn't work either and uninstalling / reinstalling the Conextant audio drivers didn't solve the problem). - None of the USB 2.0 ports on the dock are working (they do appear to have power as the light on my WD Passport is blinking when connected). The USB ports on the laptop itself work fine. - When connecting a non-USB 3.0 device to the USB 3.0 ports also these DO NOT work (keyboard, mouse, external HDD with external power, USB stick, none of these) - The OneLink dock tray icon briefly appears when booting showing a status that the dock is not connected (Windows device overview however shows it with status connected through USB 3.0). I've tried removing all USB devices through the Windows deivce manager and reinstalling, updating / reinstalling drivers etc. etc.  I suspect it's either a driver problem or even potentially a hardware issue. Any help / suggestions would be appreciated!

(Code 43)A request for the USB device descriptor failed.When I look at the Driver info for "Unknown USB Device" - the driver version is 6.3.9600.16442 with a Device Date of 6/21/2006.  Seems hard to believe that a 2006 driver would be the right one.  But when I attempt to update the driver it says I have the most up to date version.

I have this on every X1 used with the OneLink+ Dock...Any suggestions - or solutions?Many thanks in advance! Scotty

USB 2.4Ghz mouse doesn't work on any of the Dock 2 USB ports. Same mouse adaptor works right away when in the ThinkPad USB ports. Tried a couple of other USB devices, old an new, and none work in the Dock ports even though they work fine when in the Win 10 ThinkPad as well as in another older Win 7 laptop. Checked all Win 10 drivers are latest versions, tried the disable/enable toggle, all to no avail. The Dock itself is hapilly driving two monitors and seems to otherwise work fine.  The always-on USB port on the back has power, and so does the one USB port on the front (but neither work for USB connected devices). This is a brand new setup, hoping for a trivial solution otherwise I will chuck this whole thing, at this age this should be plug and play. Suggestions?

A:VGA and HDMI Ports Not Working

The projector simply says NO SIGNAL.  Yet on the same projector when I connect my E5450 it will project just fine.  This happens when using a TV using HDMI as well.
In all cases it SEES the projector or TV screen as a second monitor.  I've popped open the PROJECT app and told it to MIRROR the screens.  I can see the monitor add itself to DEVICE MANAGER when plugging in the HDMI cable and see it leave when unplugging it. This happens with Windows 7 and Windows 10.
I had a an old M4600's connected it to my TV.  It worked for months on Windows 10 then suddenly would no longer put out a signal over HDMI.  Again, I can see the TV by correct name in Device Manager when it's plugged in, I tell it to MIRROR or even EXTEND the desktop and nothing happens but NO SIGNAL on the TV. I pulled out an even older M4600 one that had been offline for about a year and it worked until MS did updates.  I went through the Dell updates and Windows updates and will no longer work - NO SIGNAL.  
I put a brand new fresh Windows 10 image on the first laptop (that I had been using for months) and it no longer works - with a brand new image from MS.  I tried updat... Read more

A:HDMI Ports not working

We cannot speak to the untested Windows 10 on this 2011 PC. We have no idea what drivers Microsoft would push for Windows 10 or how they will react with this older hardware. We can only troubleshoot the ones with Windows 7. Are you using Fn + F8 to switch to the TV/projector? Also, Nvidia Optimus must be Enabled.

Hey guys, hope your all well.So recently I got an extra display to plug into my hp envy 750-129ns so I can use an extended display. The problem is that the only 2 hdmi ports avalible are the ones located at the bottom, I think where the sound things are, and they don't do anything when I plug my display hdmi into them. My video card has only one hdmi port, and the other 3 are just DisplayPorts not hdmi. The screen and cable work fine as when I plug it into this it works. The problem is I need another port to plug my other display into.Is their any reason why these 2 extra hdmi ports are not working? The has a little plastic protector cap plugged into them. Are they just optional extensions that I'd have to get installed, Or am I missing some drivers?Thanks for any help,Alex

I am tying to install a OneLink Pro Dock to my ThinkPad Carbon X1 and am getting power to the laptop (battery is charging), but no docking capability. The red power indicator light won't go on. I have updated the driver and the firmware. I tried Lenovo phone support, but since I'm out of warrany (both the Thinkpad and the dock), the tech tried to help me troubleshhot but didn't have any solutions. Any ideas?

Hi, I had my Think Pad stolen, and bought a Flex 5. Can I use my OneLink Pro dock with the Flex 5?  How?  Thanks in advance.

Hi jvasco,
 
Welcome to Lenovo Community! And happy to have you here.
 
Short answer will be no, due to the lack of OneLink connector from IdeaPad Flex 5.
  
I hope the above information helped you.

Anybody know of a difference here??? we bought Carbon X1 Gen4's, come preinstalled with "ThinkPad OneLink Plus Dock" (v1.10.11) appearing in Programs and Features. The OneLink+ dock connects, recognizes all the hardware and all ports work (video, ethernet, USB).   If I install our company image and then download drivers from here: https://support.lenovo.com/us/en/solutions/acc100252 I see "ThinkPad OneLink All Dock" (v1.10.16) appearing in Programs and Features.  I can get video and audio through the dock but Ethernet and USB are unrecognized, no new devices in Device Manager.   I cannot find a v1.10.11 version of the OneLink+ driver and feel like this might be my problem.  I was wondering if anyone had seen a similar problem or if I'm barking up the wrong tree.   BTW, Lenovo tech support wants send me a replacement system, blaming the motherboard but I am less then confident in their troubleshooting methodology! Thanks!

We got about 5 Yoga 460s brand new with OneLink+ dock systems.  All of them have been updated with their respective updates in regards to BIOS, Firmware for Dock and Network drivers.  We are having a problem with ethernet adapter (when docked) dropping connections for about 1 second (causing Windows Explorer to say we disconnected from network drives). I can't see any "icons" drop (for network connectivity in notification center of the bottom right).  All are running Windows 10 with latest updates.  Pressing "ok" reconnects instantly but this is becoming a very annoying problem with people have to do this 6 times a day.   Lenovo machines plugged up before these docks and Yogas (T540s and T460s) in their own respective docks didn't have one issue.  Nothing on the network switch is indicating a dropped connection (managed switch put into logging mode).  We have turned off all power management of the network driver (allowed to sleep and "green" switching) to no avail.  This seems like a USB3.0 problem and we can't seem to figure it out.  Even without ANY external displays attached we get disconnects about 6 times a day (in 8 hour work day).

I just bought Onelink+ dock 40A40090UK and I am using X1 carbon (Gen5). Unfortunately, my X1 Carbon (Gen 5) has no port to connect the Dock because the Dock came with a cable that is neither type c nor USB 3.0 Does anybody knows any adapter that can convert Onlink to type c. Thanks

Unfortunately, your system has OneLink+ dock connector and the dock which you have to use is ThinkPad OneLink+ Dock (40A40090SA)
And there is no such Adapter/cable to convert OneLink+dock - OneLink Dock.
 
I hope the above information helped you.
