Lenovo X Series ThinkPad :: 2014 X1 Carbon (Gen 2) - Ethernet Dongle Stopped Working
Jun 4, 2014
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 was recently given a new X1 Carbon type 20A8 (the new 2014 model) at work. From what I've read online, it should have come with a ethernet dongle for the proprietary ethernet port on the right side (see picture below).
However, our IT guy knows nothing about it. I tried calling tech support who referred me to sales. When I called sales, they didn't even know it existed and told me there was only a USB dongle. I also can't find it for sale anywhere on the Lenovo website.

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?

This Lenovo X1 Carbon (2014) screen starts randomly flickering when traveling in trains and running on battery. We already ran all system updates and it happens less often, know but it happens. Here is a video of how it looks like: [URL]

Just received my new X1 model# 20a70037-US last week and right out of the box the screen was already flickering. When the laptop is booting up in the POST screen you see a bunch of little white dots all over and as soon as you get to the windows login screen the flickering begins. Just like on this video I found online [URL] ....
I uninstalled the Intel drivers and now it's flickers less and the laptop is somewhat usable. I should be receiving my replacement unit this week, can't wait to have this laptop working 100%.

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.

On my new X1 Carbon, I can only do CIFS sharing via Ethernet. If I connect via WiFi, sharing stops.
Both Ethernet and WiFi are listed as private networks, so I would think they have the same settings. How can I get Windows sharing to work over WiFi?

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...

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 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 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.

Sometimes the machine does not show any wireless networks and I have been able to solve it by turning on and off the hardware switch for wireless on the back of the machine. This time I can not get the machine to find any wireless networks. I am running XP. The only think different that I noticed is that MS Security Essesntials has ended support for XP.

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.

For whatever reason my ringerprint reader stopped working. I've uninstalled and re-installed the driver, software and done just about everything I can find online.
In the device manager it usually shows up, but sometimes doesnt. In the control panel>biometric devices, it shows up less often, usually only after i've clicked "Scan for hardware changes."

Recently my fingerprint stopped working for power on and Windows login. Fingerprint reader setup utility started to show some strange error followed by empty utility window (see screenshots below).

I have updated all the software using "Lenovo update and drivers" but it did not work (BIOS image also was updated during this process). I doubt that it is hardware fault because I have Linux OS installed as dual boot among with Windows, and no problems there with logging in using fingerprint reader (fingerprint-gui package)...

I keep getting a message on my laptop: Catalyst control center: host application has stopped working.
This has started happening after I tried to do a BIOS update last week and I ended up with the blue screen of death & had to recover my whole laptop.

I just got a W540 running Windows 7 x64 at work. I have an ExpressCard ethernet adapter (A Belkin f5u250), and I'm having trouble getting it working.
I used this card on a W510 running Windows XP for years with no issues. I can still plug it into that laptop and have it work just fine. However, when I plug it into the W540, nothing happens. Windows does nothing. It doesn't act like it's trying to identify hardware, go find drivers, or anything. Nothing shows up or changes in the device manager, either.
I've tried doing the "add legacy hardware" thing in device manager, but I've had no luck with that, either. If I do an autodetect, it doesn't find anything, and if I manually browse to the driver, it then brings me to a list of devices, and the list is empty.
Is there something special I need to do to enable the expresscard slot, or enable plug and play for it, or something?

What build in program in New X1 carbon is for optimizing (Maintainance) SSD? I believe the "defragment tool" provided in control panel is no use for optimizing the SSD?

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.

The label on the charger says:
MODEL 45N0261
FRU P/N 45N0262
Lenovo P/N 36200253
It was advertised as X1 charger, but when it arrived I thought it's too small in size, so I googled it. Having done that, I've realised it's actually being sold by Lenovo as a charger for Yoga.
Am I safe to use this charger for my ThinkPad X1 Carbon (3460-CLG)?

Bought a unit with this problem: As soon as I unplug the AC Cord from the laptop, it power off without notice and can't power up the laptop. It seems like the battery is not giving power .When I plug back in the AC, I can press the power button.
One strange thing is that the battery is 100%, state : good. Tried the reset battery so now 3 cycle counts. The thing is that if I unplug the AC cord only from the power outlet to the ac adaptor then the power is still up, the brightness goes down a bit and then power off without notice.
Tried:
- the battery pack switch
- removed battery backup
- removed and reset the battery pack
I'm out of options and I would be glad if I can find what cause that "unswitchable thing".

When I plug in the AC adapter, my x1 shuts off right away. I have to reset the time in the bios to get it to work again. This happened right after I changed the keyboard. Now, it seems to be permanent issue. I thought it was an adapter issue but I have two adapters and both work fine.
