Lenovo X Series ThinkPad :: X1 Carbon Touch 3444CUU - WiFi Adapter Just Randomly Stop Working
Jan 19, 2013
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 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.
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?
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 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.
On my new X1 Carbon, with a new Netgear R8000 router, The X1 will not hold a wifi connection, even 3 feet from the router. There is plenty of signal strength on all 3 channels. It connects for a while, but then the icon turns to "limited", and I have no internet connection. It works with my older Netgear WNDR 4500. Xirrus Wi-Fi Inspector sees the three channels with plenty of signal, but will not plot them. I even tried reducing the maximum rate to 289 Mbps, and it still will not maintain a 5 GHz connection.
(There is another thread on this, but it relates to Windows 8. I am running Win 7 Pro 64 bit.)
I have a Thinkpad X1 Carbon type 3443-CTO. The Wi-Fi adapter -- never the stablest thing on earth -- is getting flakier and flakier. I am constantly having to reset or disable/re-enable it. The "connect automatically" settings for some of my existing Wi-Fi routers do not appear, so that I have to connect manually every time.
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!
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 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 (188.8.131.52 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've updated my Intel Wireless LAN Driver to 184.108.40.206 and since then every time I close the lid (I'm connected through a OneLink docking station) the wifi stop functioning normal (connects to network but shows "Limited" and practically not functioning). If I open back the lid everything goes back to normal, either directly on the laptop or while still working through the docking station.
The issue was in regards to WiFi not working properly on my Lenovo ThinkPad Yoga S1. After a restart my computer's internet (with WiFi on) would work for a few minutes then it would stop. Long story short, I tried various things, and even uninstalled Norton and other software which I thought may have been a culprit but still the same issue. I also used a USB to Ethernet port (since there is no built in Ethernet port in the ThinkPad Yoga) and connected my computer with a cable and disabled the WiFi to see if it was the wireless hardware not working. Unfortunately still the same issue.
Finally I noticed in the Windows Task Manager a process called "Discover.exe". It turned out this was using some noticeable amount of CPU and wondered what this was doing as I hadn't seen that before. I found out that this was a piece of software bundled in with my computer called Lenovo EMC Storage Connector. I'm not sure why it was running but I ended this process.
Suddenly my internet was working again! This time no problems. I uninstalled this software utility to make sure this doesn't cause this issue again.
I have a problem with my L530 and the WiFi Connection. When I start the computer and see the Login-Screen of Windows 8.1 the networkicon left to the betteryicon have a red cross. After I log into Windows 8.1, I have no wireless connection availible. In the devicemanager is no wirelesscard listet, also there are no other problems with other devices.
After restarting, power off/on, removing the battery and so on about 1.000.000 times the wireless card is pretty working to the next shut down. So my workaround was to use the standby mode instead shut down after I've finished working.
UNTIL yesterday! Now I can't enable the wireless card... This card is installled: ThinkPad Wireless LAN (11bgn, bg)
I've tried the following things: - UEFI is on version 2.56 - loading UEFI defaults, save and reboot - remove the battery and power plug -> push the power button for 10 sec - disable hybrid shut down in windows - booting with ubuntu 13.04 -> no wireless hardware available... Nothings works...
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.
Since updating to ThinkPad Bluetooth software 220.127.116.1100 on July 28, 2012, my ThinkPad Bluetooth mouse will stop working after using it for several hours. Disabling power management in Bluetooth does not seem to solve the problem. Please provide a download link to the prior version of ThinkPad Bluetooth software until this issue is resolved.
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.
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.
- 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.
