I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I bought two brand new X270's WWAN upgradable and bought EM7455 cards separately. I installed the cards as directed. When I booted the laptop the first time after installation, a warning message saying something to the effect of "unknown network hardware EM7455." Windows didn't detect the newly installed card. So I did a CMOS reset (removed the extra battery, disabled the built-in battery on the BIOS and pressed the CMOS reset button to the left of the battery bay). After the CMOS reset, Windows recoginized a new hardware by the name of "Sierra Wireless EM7455 Qualcomm" but couldn't install the driver (see the attached screenshot). I did install Lenovo's EM7455 driver (total file size 191MB) and didn't work. I turned to Sierra and found a generic USB Build 4581 driver and it didn't work. When I restarted Windows, the newly found hardware was gone. I did a CMOS reset again and it came back up on the device manager list.  So I turned to Windows update. It found a driver update by the name of Sierra Incorporated - Ports dated 10/20/2016. It tried to install it but it failed. However, the device's name was changed to Qualcomm COM Port (3) and it was still not installed properly. I went to the device's properties and changed the port to 8. It recognized the full name of the card but GPRS connecitons on Windows didn't show up. I restarted Windows, and the device was gone again! I checked the BIOS permissions and I tried different scenarios (disabled WWAN, e... Read more

I have a Carbon X1 with a cellular card - it says:Manufacturer:       Sierra Wireless 
Model:                    Sierra Wireless EM7455 Qualcomm
Network Type:      GSM

I put in a Three (UK) prepaid data SIM, and.... nothing.
It asks for APN settings.  I've put in what the Three site suggests; nothing.  Network settings persists in telling me that Cellular is "switched off", without any obvious way to switch it on.

Hello, I just unboxed a 470p and created a reference image in SCCM/MDT using the SCCM package from the download page. Everything worked fine until the point when I tried to use the built-in WWAN device. It worked exactly once and I was able to dial in to the intertubez. Hanging up, recreating the reference image with a few changes and testing again never brought the device back to life. Over a timespan of a few hours it has gotten worse and worse and now it's not working anymore at all. It's not even visible in Windows' device manager anymore. (Hidden devices displayed). It's just gone. Running any linux and doing an "lspci" or "lsusb" doesn't show the device either. I'm under the impression that the card just died and that's it. Over the last few hours I was able to make the device visible again by just resetting the BIOS to its defaults and boot. So it was accepting a PIN again, but couldn't find a network nor was it accepting any APN configuration at all. Before we start speculating:After the first time the device worked it never worked again. This is what I did: - Flashed BIOS to latest version (1.14/1.02)- I tested multiple SIM cards from different german providers, none worked.- I removed the driver from the reference image that comes with the SCCM package and installed the driver manually- I tested multiple versions: R0GWS10W (latest available), NZ1WN03W and N1HWL05W.- I always reimaged with a clean image before testing a driver I also not...

The EM7455 on my P51 failed to work recenlty, it shows the carrier with a no signal icon and "no service" text, not sure if it's caused by a driver update or something else. I tried the driver from sierra or older version from lenovo, but none of them works.  On the setup popup, the progress bar stops at 37% and failed with error code 81. I tried run firmware update downloaded from sierra but it also throws a "fail to reset (error code 81)". I also tried the registry editor to disable firmware update, after that the setup popup won't show but it still has no service. Anyone knows the solution for this problem? Is my EM7455 broken?

I am installing an EM7455 WWAN card in my P70. The User Guide states that the SIM used by the system is a Micro-card. When I called Verizon Wireless to obtain a 4G-LTE card, they could not find the P70 in their database. However, they said they knew the size and shipped me a SIM card. Unfortunately, it was the incorrect SIM-card size (apparently there are multiple) so I have to obtain the correct card from a Verizon store when the WWAN arrives from China. The model number of the card needs to end in 3FF-A. It would have been really convenient if the Verizon SIM card was orderable on the Lenovo website at the same time as I ordered the EM7455 from the Accessories storefront.

Has anybody else seen this or can you recreate the problem? The Sierra Wireless EM7455 LTE card keeps crashing the PC.  But exactly as follows..... You are connected to the internet using the EM7455.  You sleep the PC while connected.  You wake the PC.  EM7455 cannot connect again.  EM7455 is also lost from Device Manager.  A scan for new hardware just hangs and freezes the Device Manager window.  The only option is to restart the PC.  BUT...if you sleep or hibernate at this point (instead of restart) the PC crashes with BSOD (ntoskrnl.exe error).  This happens every time, without exception.  All the drivers are the latest, currently 7.44.4709.0102.  Firmware is 2.24.03.  I tried to upgrade to 2.24.05 from Sierra Wireless but it keeps reverting to 2.24.03 (must be a Lenovo OEM things that prevents the update).  Any ideas?  (apart from disconnecting before sleep!) Thanks

Received new Lenovo T470 with Sierra Wireless EM7455 and booted it.  Default windows drivers for the WWAN, so I downloaded latest Sierra Wireless drivers from Lenovo's website (NZ3WN03W 17.11.0130.37).  Installation was going fine, but when the installer prompted "Configuring your mobile broadband device - 68% complete. Do not shutdown or restart Windows" the system BSOD'd and now I cannot get the drivers to install - swmbbser01.sys will not load and only windows drivers are used even after completely uninstalling the drivers and removing any devices or pnp driver store packages via devcon.  The laptop came with a restore point but it seems like it's corrupted and I can't revert to that state.  Does anyone know of a reliable way to get the drivers to install cleanly? I have tried power cycling the card by disabling internal battery in the BIOS

I have an X1 Yoga 20FQ with Windows 10 Enterprise 64-bit and a Sierra Wireless EM7455 WAN card that came with the unit from Lenovo and an AT&T micro SIM card (also in the unit when it came from Lenovo). I also have the latest Lenovo software for the Sierra Wireless card (v. 7.47.4743.0105) from the Lenovo web site. The WAN card will connect to HPSA on AT&T (using the "default APN" and "broadband" in the Win 10 settings) but it will not connect to AT&T LTE. The AT&T web site at https://www.att.com/esupport/article.html#!/wireless/KM1218316 says to use NXTGENPHONE as the APN, but when I input that as the APN the card does not see it at all. I know that NXTGENPHONE is the LTE APN because that is the APN that my cell phone uses for its LTE data connection. AT&T tech support told me I the Windows 10 and NXTGENPHONE APN settings are correct and the AT&T diagnostics show I an LTE connection is available to me.I realize that there can be sources for this problem (Win 10 or AT&T) but I thought I would ask here to see whether anyone has experienced the problem or has a solution.Thanks.

I recently installed an EM7455 LTE modem (FRU 00JT542) and antenna kit (FRU 01AW958) in my X1 Yoga running Windows 10 Pro.Drivers installed fine and I have nothing unidentified in Device Manager, and "Cellular" exists in the networking panel (when you click on the network icon in the taskbar).However, none of my SIM cards are being detected by the system. I've tried T-Mobile and Verizon SIM cards (both verified working in other devices) to no avail -- Windows keeps telling me to insert a SIM.I spent all afternoon on the phone with half a dozen Lenovo support reps (and have a ticket open with them) but we haven't made any headway yet. Here are some things we tried:Different Windows 10 installations (the original image on the supplied SSD vs. the one I created and have been using on my 950 Pro): no effectThe Windows 7 Mobile Broadband Activation tool: errorVarious Gobi 5000 Drivers: no effectUpdating UEFI: no effectWindows Troubleshooting: uselessI'm beginning to think it may be a hardware issue with the SIM slot but the reps haven't been willing to admit as much. In addition, I only have the depot warranty which I've heard atrocious things about, so I'd like to avoid that. I was also informed that they don't allow self-replacement of system boards so worst case I'll have to shell out for an onsite warranty.I'll take any suggestions -- even if they're shots in the dark!

The performance of the SierraWireless EM7455 WWAN LTE modem in my X1c Gen 5 leaves much to be desired.  Among its flaws: It takes about 10 seconds to wake up when I resume the laptop from sleepIts sensitivity is really, really, weak.  I know it's bad because I used to use my old X1c3 in the exact same spots and it used to work much better.  My 3-years old iPhone 6+ also has much better/stable data connectivity.Sub-par WWAN performance with SierraWireless products fitted by Lenovo is nothing new.  My old X1c3 came with an EM7345 WWAN modem, which suffered from well documented issues in its days. Thankfully Lenovo realized the performance wasn't adequate for the premium products it was sitting in and slowly but surely improved the performance (see previous link for history).  So in the last 6 months or so (out of 2+ years!) of using my X1c3 its performance was finally adequate.  Sadly "upgrading" to the EM7455 is a massive step back! Please post your experience with the EM7455.  Maybe I have a faulty unit?  If not and they're all as bas as mine, we need to make some noise so Lenovo picks up the issue.

I bought a new P71 portable workstation with this WWAN card already installed and I've got a SIM card from Bell Mobility in Canada. The card seems to be activated but there is a very limited traffic. I ran the diagnostic and it says that there is a second PIN that need to be provided. I followed the instruction from my provider to unlock the SIM card, but the diagnostic is the same. I donwloaded the suggested driver from the Lenovo support page but the installer indicate that there is nothing to update. I'm looking for a new direction to look for to solve ths problem. Thanks Dominic

[OS: Windows 10] Is there an application to use for sending/receiving SMS messages with the Sierra EM7455 Wireless WAN card? What I am looking for isn't one of those bulk sending applications that connects to some server ove Internet. What I want is to send and receive SMS messages just like the way I can do so on my phone. I am really hoping someone knows of such an app, because all googling efforts turned out to be useless.

Lenovo why you lock the com ports on the Sierra Wireless EM7455 ????? USB composition for the EM7455 is set to 9, which is MBIM only. I need to have MBIM and also COM ports for the AT commands and NMEA GPS data. So I need the USB composition 8My question how to enable the com ports again ???thank you in Advance...

A:Sierra Wireless EM7455 COM ports are Locked... Lenovo Why do you do something like that?

Hello and welcomeThat's not a Lenovo deal to lock the ports, more clearly, to choose appropriate default USB composition. MS and Sierra do that. To change default USB composition change Sierra wwan card drivers installation configuration and reinstall them. Edit the configuration.ini file within the drivers package:- [Default Values] section- USBCOMP=x parameter (choose 8 as you want).
