Lenovo X Series ThinkPad :: 2014 - X1 Carbon Flickering Screen
May 25, 2014
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%.
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]
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.
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.
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.
My W530 laptop is new. I finally got it all loaded up and ready to work with and then I started to get screen flickering issues. The screen will flicker all different colors and then it will restart the computer. The computer will start up and act normal. I have video of the issue.
The audio in the video is not from the computer. [URL] ....
I bought a new X1 Carbon (20A7) a week ago and from time to time the laptop gets stuck on the ThinkPad splash screen when booting. I have to hold the power button to turn it off and then it boots fine. My brother has this problem with T540p, although this happens to him a LOT more often (also, if he waits patiently for 10-20 minutes, the system boots eventually, I havent tried that on my X1).
It doesn't matter if the AC is connected, whether there is something connected to USB ports, whether it was a restart or just normal boot, there is no pattern that I can see, this seems random. We tried updating the BIOS to the newest version, our USB ports are not bent or anything, the SSD with the OS is set as the first boot device. This still happens. I see there are more people with thinkpads who have the similar problem, but their solutions do not apply (if there were any).
How well the X1 Carbon keyboard and screen have been for using it for software development.
I use Visual Studio and Remote Desktop quite a bit and have some concerns regarding the screen and keyboard. I don't want to get a Hi DPI screen and have to workaround the limitations of the OS. Are there issues with the RDP client and the Hi DPI screen?
How has the keyboard been for someone who uses the function keys 10% of the time? I usually rely on memory to know where to press the F3, F5 keys. I'm concerned it will be hard to find the right location without physical keys.
I have an S440. I've had it for one week. Two days ago I downloaded the Windows 8.1 update from the store. Since then, when I start up the computer, it doesn't even taken me to the 'sign in' screen. There's just a black screen. When I move the cursor, it briefly appears, flickers, then disappears again.
I understand this is an issue with the graphics drivers. So I ran Windows in safemode and disabled Intel R HD Graphics family and AMD Radeon HD 8600 series graphics drivers.
This, unfortunately, hasn't fixed the problem. It still boots to a black screen with an occasionally flickering cursor. I'm currently running in safemode.
When I watch a video clip, I experienced my X1 screen automatically got dimm when background gets dark. So it became even more darker and I cannot see anything. But it gets back to bright when background gets light.
I just got my new carbon touch thinkpad today, and I couldn't be happier, until I closed the lid and reopened it a couple of minutes later. The screen froze for a while and then I got a BSOD with the notice CRITICAL_PROCESS_DIED. I hoped it would be just some coincidence, and updating my drivers and installing windows updates would solve it. So I did, and closed the lid again. After reopening it, I got the same error. So I figured I could just as well restore to my factory settings. Without luck. After updating everything for a second time, still no luck. I check the disk and did a memory check, but everything seems fine. The lenovo Solution center isn't reporting any issues either. I looked into the minidump created by the blue screen, and it seemed the process failing is called csrss.exe.
I have a X1 Carbon 3443CTO and it's running fine.Last night everything was ok and I went into the BIOS and changed AHCI to compatibility (don't ask me why, I was doing some testing), then I went "Exit and Save Changes" (at the last page of BIOS). As soon as I press Enter the screen freezed there (as opposed to reboot)Since it hangs there I hold the power button and it shutdown.Then I power it up again, but now, here is the problem:
1) The computer turns ON, keyboard backlight flash on for a second (normal) 2) Screen stays blank (no, it's not the backlight faulty) 3) power light turns ON (normal) 4) no sign of activities pressing any buttons, no beep sound
It's been a yeah that i work on this X1 Carbon laptop and no default. I got a windows update yesterday, i did it and my computer powered off naturally. This morning, i cant start it, It boot well, Lenovo sign appear but nothing after. only black screen with blinking underscore.
I just got me a W540 with docking. It is connected with two Samsung 24inc screens. They are connected with two display ports kables from the docking. I also have a wireless logitech mouse and keybord. And a Jabra headset connected.I have reinstalled it with windows 8.1 And now I have a serious issue that both screens turns off randomly while I work. They go black for 15 sec. And then re-appear. It seems like the computer looses all USB connection also while this happens. I sometime get an error msg. saying that I connected a USB device that cant be recognized. But most of the time nothing happens.
All 3 of us at work who has a W540 has this issue. So it must be known by Lenovo. I have an ongoing case with the support. But dosnt look like we are getting anywhere. They gave me this to try: URL...We think it could be a driver issue with the USB or that the computer is swiching between the Intel and the Nvidia gfx card.I think I have tried about everything, but can not figgure this one out. I have all the latest drivers from Lenovo installed. Tried to use a wired mouse and keyb. no change, tried with a DVI and Displayport to the screen. No change.
Here is a link to Lenovos System report on my W540. URL...
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?
I have a 3 month old X1 Carbon. Last night i turned it off and suddenly today morning, I find that the device is not powering on. What's the deal? No response at all even after continuosly pressing the power button.
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.

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?
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.
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.
Have a brand new X1 Carbon running windows 7. It originally came with Windows 8 but had to downgrade to run a necessary work application (which could be the problem). My battery never exceeds 50% even when plugged in for extended periods. Also, I am not seeing any of the "Rapid Charge" that was promoted.
I recently put Windows 7 64 bit Enterprise on a brand new X1 Carbon Model 20A7-CTO1WW and I have a missing unknown device in device manager and when I searched for it I came across nothing for the X1 Carbon I found posts on here for X240. The little research I did I did see someone mentioned it could be the fingerprint scanner. Tried that and it did not work. Also Ran system update and that did not work....
Here is the hardware ID : USBVID_138A&PID_0017&REV_0078
I am trying to install windows 8 from the 3 disks that came with the X1 Carbon. There is no DVD drive and we have no external disk drive, so I need to create a bootable USB for this. The laptop came with windows 7 on it.
It is easy to use DISKPART to ready the USB as a bootable device, but how to I take the data from the 3 DVDs and put it onto the USB so that it works? The first one only has drivers but the OS install is split onto two disks. I referred to a KB article but it was talking about autorun files that are not present on these DVDs.
The DVDs I have are labeled as
(1) Applications and Drivers Recovery Disk, (2) OS Recovery Disk Windows 8 Pro [Disk 1 of 2], and (2) OS Recovery Disk Windows 8 Pro [Disk 2 of 2].
where is the printscreen button on the X1 carbon ? Where is the insert botton ?
The keyboard of the X1 Carbon is non standard compliant. The person who took keyboard classes and efficient at typing becomes inhibited with these changes The End botton is close to the A key which is usually the spot for the Caps Lock
