Lenovo X Series ThinkPad :: X1 Carbon - Fails WWAN Connection Yet SMS Working
Apr 8, 2014
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 X1 Carbon with Sierra EM7345 WWAN modem. It is all installed perfectly - drivers etc. But id does not recognize the SIM card. I have googled a bit and I can say that:
1) I have the drivers OK, I have the WWAN network adapter etc. 2) I have inserted the SIM card correctly
The SIM card works perferctly if I use the USB 3G stick instead. So the problem is not in the SIM card. I think there is some configuraiton of the Sierra modem which should be done - to switch to 3G/2G or something.
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?
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.
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 (126.96.36.199 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 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.
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 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.
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.
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
I recently purchased a Lenovo X1 carbon, the weird thing is that the computer functions correctly when the power cord is plugged but when the power cord is unplugged the computer DOES NOT turn off no matter what you do. It restarts all the time. If you plug the power cord you can turn off your computer, but when you unplug it it starts working immediately?
In any case pushed the reset button on the back of the laptop but it didn't worked.
