Lenovo X Series ThinkPad :: X1 Carbon With Dock - External Monitor Not Working
Jul 27, 2013
I use the Displaylink dock to connect to an external monitor, but it has suddenly stopped working. The error message said "check connections". I have done so - replaced the digital video cable between dock and monitor with a new one, cycled both dock and monitor on and off several times, but windows can not find an external display.
The Lenovo settings app has been giving me an "updating... " message for 3 days (I have raised a query on that elsewhere) so I can't use that to check out the display problem. I should say the display problem started today, and the "updating.."

I have a X1 Carbon and a OneLink Pro dock. I have it setup with evey thing working, no issue's whatsoever. My concern is that when the laptop is completly charged while connected to the dock, is there any way to switch to battery while staying connected to the dock to be able to use the extrnal monitor, ethernet, and usb ports etc?
What i have noticed is that even when the battery is 100% charged , the dock keeps charging as the battery doesnt fall below 100% and in long term it will reduce the battery life.

We have one setup with 2 Dell 24" Ultrasharp monitors (U2412M) using the display port and DVI port. The fact that I couldn't get native resolution of the screens when having dual monitors is strike one but I understand. If you only have 1 of them i would get native resolutions with the display port.
Anyways I had problems with the machine crashing and always when docked. I made sure the dock had the latest firmware and that the driver was also updated. It crashed so much that eventually the hard drive got corrupted. It kept showing NTFS errors so Lenovo replaced the drive for me. I was really crossing my fingers hoping the drive was bad in the first place thus all my problems.
Nope it still crashes! The client just can't use laptop with the onelink pro dock. I already have the latest drivers too.

Since I'm using LAN internet, My X1 Carbon is always connected to ThinkPad Dock at home use. In addition to connect the internet, the Dock is always charging my battery. AFAIK, the battery life will be shorten if it's always charged/plugged. Its better to work on battery after 100% charged and return to charge if asked to.
I just worried, is connecting to ThinkPad Dock after 100% fully charged can shorten X1 Battery Life?

I have an issue with the OneLink dock and the ethernet port. Initially it was working but after a BIOS update it now always gives me "Unknowns USB device".
I just got my hands on a i7 X1 Carbon 2 and a OneLink Pro dock and at first it all worked out as it should.
After a while the "System update" prompted me that there were updates I let it run, including an updateof BIOS from 1.06 to 1.07. Now I can no longer get it to work.
Whenever i plug it in i know get: Windows has stopped this device because it has reported problems. (Code 43)
The SuperSpeed link to the USB device keeps going to an error state Compliance. If the device is removable, remove the device and then disable/enable from device manager to recover.
I even did a full system restore and started from the beginning...

How can I configure Bitlocker in X1 Carbon using Win8.1 so that the laptop won't ask the freaking Bitlocker Recovery Key every time when I boot the laptop IN the OneLink Pro Dock station AFTER I've used the machine WITHOUT the docking station (or vice versa)?
Bitlocker works OK if I boot the laptop every time in same mode (using always docking station OR not using it ever). However, I need to use the laptop in both modes; with the docking station (at work) and without it (at home and when travelling). And I'm not wanting to type the looooooooong Bitlocker Recovery Key every time when I boot the laptop in different mode.
How can I tell for the Bitlocker that both these modes are trusted ones?

I am to be the lucky owner of an X1 Carbon soon. There is one thing that I can't find the answer for in the documentation and spec sheets:
- what is the maximum resolution that the mini displayport can handle?
The display that I'm looking to buy is running 2560 x 1080.

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 that might have resolve the issue but have not had any luck.

I have a T420 that I'm using with a Mini Dock Series 3 - 90W 433710U docking station. I'm trying to connect to two external monitors (both HP 1965's) using the DVI and VGA outputs on the docking station. From the VGA output, I'm running a VGA (M) to DVI (M) into my monitor. I can only get either the DVI or VGA outputted monitors to work by themselves, but not together. When I connect both external displays, it will switch off one of the external monitors (the first one connected). Both are verified working as external monitors with the T420, just not at the same time. When using the DVI output, I can get dual monitors to work using the ThinkPad display as one monitor and the DVI-connected external monitor as the second. Is there a way to connect to two external monitors from a T420 with a Mini Dock Series 3 - 90W 433710U docking station? Or do you a multi-monitor adapater, such as an Cirago HDX3DV01 to do that?

I only bought the one link pro to connect my Thinkpad Yoga 2 to my Samsung monitor with WQHD-Display with 2.560 x 1.440 Pixel. Lenovo told me that this is possible. With DVI I only get the maximum 1920 x 1200 which makes round circles look like eggs...
I need the full resolution.
I there any configuration, cable, display port instead of DVI cable?
(I have the newest, best, DVI cable (forgot the specification for high resolution DVI cable, ports)).

I currently have an issue with my original X1 Carbon (2012, 3443-CTU) light not working on the LCD. I attached an external monitor to the laptop and it works without issues so it's not the motherboard. Under the right lighting conditions and angle, i can see very very faintly my desktop background.
This leads me to believe that the screen inverter is damaged, or the lcd. Since my ultrabook isn't under warranty, i believe the best course of action is to find the screen on ebay and replace it. [URL] ....
Is replacing the LCD as easy as it sounds? It looks like i need to remove much of the parts underneath the keyboard panel, and remove the LCD bezel and replace the screen. Is there something i'm missing?

I just received my Lenovo X1 Carbon; it's a very good product and I really like it. Everything is working as expected (fast & smooth) except one thing: laptop works kinda strange with the closed lid
My product code is 20A70037US, I'm running Windows 8.1 Pro.
I've chosen (in power options) that laptop does nothing when lid is closed. Yes, it works but... I'm using TeamViewer to connect to laptop; it works but TeamViewer periodically loses connection and displays message "The screen can't be captured at this moment..", Microsoft installer (I'm installing Visual Studio 2013) is paused (!), and Google Chrome won't render pages (but Internet Explorer works fine).
If I open the lid, all symptoms described above are disappear: installer resumes downloading, Chrome render html pages correctly and TeamViewer works fine (no periodical messages shown).
For me it looks like laptop not in "normal" operational state but kinda under power saving.
I've set power option to "High performance" (laptop is plugged) but it doesn't work.

the microphone mute button doesn't work, nor does it light up at all... the speaker mute button works. Also, the Lenovo button next to it USED to work and now doesn't for some unknown reason. I have a new x1 carbon with windows 8.1 and really need some specific direction on how to troubleshoot this!

For some reason, I cannot get the backlit keyboard to work on my new X1 Carbon Touch. It lights up upon powering up and then will not turn on no matter how many times I hit the space bar. I don't see an option to enable/disable anywhere either. Am I missing a driver?

The Broadband on my X1 Carbon (Gen 2) always fails to connect with an error message saying that "You're either out of service or SIM card not activated" while neither of these conditions are true. Oddly, SMS is working fine and I can both send and receive messages without problems.
What could be wrong? How can I diagnose and fix the issue?
Some more details:
- The ultra-book is a Type 20A7 which came with the SIM slot but no broadband modem. At that point Access Connections showed the Broadband option greyed out. I had to call support to find out why and that's when I learned there was no modem.
- Support told me to order part number 04X6038 which is a Sierra Wireless EM7355. After installing the latest driver, the Broadband option was now enabled but it still failed with the error message mentioned above.
- At the wireless store I told them it was not working and they gave me a new SIM card. This time I received a welcome SMS message. i tried sending to a few numbers and replying which works.
- The wireless provider took the IMEI number of the EM7355 and confirmed it was compatible which seems logical considering SMS is working.

I have a ThinkPad X240 laptop with Windows 8.1 Enterprise x64 installed. Sound plays just fine from the laptop's speakers, and when I plug external speakers into the laptop's 3.5mm audio port they work just fine too. when the laptop is docked in my Ultra Dock 90W docking station and the external speakers cable is plugged into the dock's audio port, no sound is heard. If I'm playing music through the laptop's speakers, as soon as I plug a cable into the dock's audio port no sound is heard. I can still use the laptop's audio port to connect external speakers, but that defeats the object of having an audio port on the Ultra Dock.
The Ultra Dock has (I believe) the latest firmware installed (version 2.22.000) and I have the latest audio drivers installed: in Device Manager > Sound, video and game controllers > Realtek High Definition Audio > Driver version is 6.0.1.7188 which is the latest available from Lenovo Support downloads. What do I need to do to get the Ultra Dock's audio port working? I mistakenly posted this message on the "X Series tablet ThinkPad Laptops" board.

I have a training environment using W530 laptops that are enclosed in an area in front of the desks. It is not pratical to get to the computer as it is hidden away and therefore I need to be able to use the dvi cabled external monitor for bios setup, boot order, etc.
Right now the boot options are hidden from the external monitor until windows loads. Then the external monitor becomes active. Any way to bypass the laptop monitor altogether?

Suddenly my FN stops working if the keyboard is on F1-F12 keys. No reaction when pressing it.
If I go into the settings and change default to something else, I can press FN until it again show F1-F12 - After that is stuck on the function keys?

I am one of the lucky ones who just got the X1 Carbon Touch (after a 2 month wait).
Touch screen is VERY spotty. Will just stop working. All the time. Even in the middle of gestures.
I found that by going to the upper right corner touch will start working again, and then it'll stop moments later in the middle of an activity.
This is Windows 8, of course. I have used plenty of other Windows 8 devices so I'm not a novice. I have never seen this behavior. Is this a driver problem? A setting I don't know about (some special Lenovo thing?). I am hoping its not hardware. The fact that touching the upper right corner enables things for awhile seems to indicate its not hardware but not certain.

I have a 2014 X1 Carbon (Gen 2) and my ethernet dongle stopped working this morning. It worked fine for the past 3 weeks but after rebooting this morning i can't get to get access to the network via the ethernet port anymore.
The port's activity lights don't light up and a network connection is never recognized.
I have checked the Device Manager and verified that I have the latest drivers (12.11.77.1 for Intel I218-LM), and made sure that the Power Settings do not allow the port to go to sleep. I have also tried 3 different ethernet dongles, all behaving the same way.
I was able to use a USB-to-Ethernet dongle to get access with a ethernet cable. Is my port just dead? I don't see any visible damage, or loose connectors.

I have a 3444-CUU that I really love. When I first got it I realised the wireless adapter would just randomly stop working. I updated every possible driver and I'm still having the same issues. All I can do is reset the adapter to get it kicking again. I'm not sure if the wifi care is soldered or if it could be removed or replaced but I'm really leaning towards it being a hardware issue.
It'll either stop working could turkey, won't detect any wireless networks or it'll stop working and I can still view other wireless networks but I cannot connect to them. Resetting the adapter is the only option. As I'm writing this right now the wireless has gone out again. So I have to reset the adapter for 5-10 more minutes of internet just so that I can post this.

I tried multiple different setting in BIOS, and am currently on
(1) Boot display device - Thinkpad LCD
(2) Graphics device - Discrete graphics
(3) OS detection for nVidia Optimus - Disabled
Shown in the screenshot is where things are wierd. With my Asus VG248HE connected via mDP to DP cable, the W530 detects the monitor, but will not allow me to enable it. When I click the white box to enable the monitor, it just thinks for a few seconds and does nothing. After the first time of thinking, it does not do anything when clicked.

We have three dock posibilities:
- basic dock
- pro dock
- ultra dock
They differentiate by the number of ports and by the power adapter supplied with them. I had an opurtunity to try my W540 on pro dock, which normally has 65W or 90W power adapter. The computer warned me about insufficient power, and did not charge on dock, everything else worked fine. The I disconnected 90W and connected my original 170W power supply to the doc. Everything is working normally since.
So, my question is: Since I don't need all the ports on the ultra dock, nor on the pro dock. Would basic dock work with W540 and 170W power adapter too?

My X1 is about 18 months old. It was fine until today. The battery was low, so I plugged it in. The little blue light where the power connects illuminated, however the battery indicater in Windows did not change to show "charging", and the battery continued to drain.
Over the next hour or so I tried many things like shutting down, waiting, new A/C outlet, new power settings, etc. Tried the little reset hole on the bottom of the laptop. Nothing mattered... the little blue light is on, but the battery just drains.
Eventually, the battery drained and the X1 shut down. When I try to boot, I get a pre-boot message about a critical low power error, even plugged in, so my laptop is now a brick.This is a 3448-34U Thinkpad Carbon X1.

I have an AC adapter left over from my first generation X1 Carbon. It is 90W/20V. The adapter that came with the new machine is quite a bit smaller, and only 65W/20V. Can I use the 90 watt adapter with the new model X1, or will it damage it somehow? Dont want to ruin my brand new computer.

I have newly bought a x1 carbon with 8g memory and i7 4660u, system win7 4 bites, the model is 20A7 CTO1WW, I didn't choose the high resolution screen because I think it is not neccessary.
But the usable momery is only 3.08gb, i am very confused and don't know what is the problem. Is it because the mainboard doesn't support 8g memory?
Here is the picture of system information.

Just got my new x1 carbon, and I like it alot, trackpad isn't as bad as everyone is complaining about. However one big issue is that I want to keep the Function row on by default, and only switch to the default one with volume controls if I press the FN button to do so. Right now no matter even if I chose not to show the default keys, with volume and cloud and all that, it still comes back anytime I switch to a different app.
