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 want to know if a Lenovo P52 WWAN card will permit me to use that laptop as an additional device in our Google Fi account, which we use for our Android phones.  The card Fibocom L850-GL 4G LTE-A cat 9 is listed as available for P52 workstations.  A Fi chat said that I should use a "data only SIM card", but that does not help me unless I know how to use that in the P52.   I understatnd that the Fibocom card is supposed to work with Verizon, but I want to know if it will also work with Google Fi.

I bought X1 Carbon 6th and X280, both with Fibocom L850-GL. WWAN with Linux do not work. I searched and found the reason. The PCI-E must be disabled, so that the card can run with USB. It seems that Lenovo did not offered a solution since July 2017.  I searched but do not find any direct contact to Lenovo to ask the question.  The WWAN is important for me and Windows is no option anymore. Anybody know if there is an other WWAN card wich works with Linux  and X1 Carbon 6th / X280 ?Anybody know if there is a chance that Lenovo solve the problem with a bios update? Many new Lenovo Thinkpads have this Fibocom L850-GL inside and many business user use Linux...

Over the last few weeks, I've had at least a half dozen T480s that have severe spikes in latentcy and packet loss when using the Fibocom L850-GL, making them pretty much useless for our users who need them for remote desktop.The usual "working" baseline for these machines on our network is around 40-70ms pings. Show below are the occasional spikes past 3 seconds and timeouts along with the current firmware.    The work around I was using to fix this problem was uninstalling the drivers/firmware from Device Manager, and letting Windows reinstall them, but that doesn't seem to be working anymore.  Any help would be appreciated.

 Hello All, New T480 with the Fibocom L850-GL wwan card. Clean install of Windows 10 Pro x64, Redstone 4 (v. 1803). All Windows Updates applied. All Lenovo updates applied through the Vantage app via the Microsoft Store, and manually checked from the support page of the website (BIOS, WWAN, etc. updates). Following the manual, I pulled the external battery, disabled the internal battery, then inserted my T-Mobile USA sim card, then reassembled everything, then rebooted. Manually installed the latest L580-GL drivers from Lenovo. First off, the L850-GL is being shown as a USB device, as opposed to PCIE, with a hardware device instance path of USB\VID_8087&PID_0AC9&MI_00\7&4FA6012&0&0000, and a hardware location of 0000.0000.0000.003.000.000.000.000.000 in the properties dialogue screen in Device Manager. The Driver tab shows the provider is Microsoft with a date of 4/10/2018 and a version of 10.0.17134.1.... I suspect much of that to be a sign that something isn't right from the get-go... Second, every time I close the lid of the machine or leave it running long enough to enduce the proper level of sleep/hibernation, the card simply stops (with a hardware error 43 warning in Device Manager). At that point, my "T-Mobile LTE" network option no longer appears in the Windows 10 notification/network connections sidebar. My only recourse thus far has been to uninstall the L850 in device manager, "Sca...

I currently have T580 with pre-installed WWAN module (Fibocom L850-GL) and trying to get to work it on Linux. It works perfectly fine on Windows. So far I discovered that Windows driver uses PCIe protocol to communicate with WWAN module, but Linux is supported apparently only through USB protocol, and if PCIe is enabled, the module ignores all USB commands according to its hardware specs document (page 26) - https://www.mev-elektronik.com/files/MEV%20Elektronik%20Service/produkt-downloads/rf-microwave-wirel... Fibocom recommendation is to disable PCIe in BIOS, that is not supported by stock ThinkPad. Thus in Linux the device is only displayed as "Wireless controller: [0d40]: Intel Corporation Device 7360 (rev 01)" through lspci , and nothing on lsusb . Any suggestions how to make it work on Linux? As an alternative I'm considering getting another WWAN module, but it's quite likely it will not work due to whitelists. The only other module that is whitelisted for sure is L830-EB, that does not have global coverage and thus doesn't work in the US or China, even so it was reported that it's Linux-compatible (USB-mode only). Maybe there is a patched BIOS that has whitelists removed? Wondering if there are Linux enthusiasts who are also looking for a way of using WWAN.

I have a X1 Yoga 3rd Gen equipped with the Fibocom L850-GL LTE modem, using a Verizon LTE sim. I ran into this issue whenever I'm using the LTE connection at high speed, Windows 10 has a high chance of crashing (BSOD). This can be easily reproduced by running a speed test on speedtest.net. I'm in an area with good LTE signal, and my speed on the Verizon sim can reach around 200 mbps. When running the speed test, whenever it goes past around 130mbps, it has a pretty high chance of crashing. It's almost as if the module cannot handle that speed (maybe heat/power related). I'm on a clean installation of Windows 10 1809 with the latest Lenovo drivers (including the Fibocom modem) installed. Anyone else is having this issue?

Hi all, I just began ordering T480s devices as the old T470's are gone, and running into an issue on one where every time the computer goes to sleep it simply states "No Connection" in the cellular section.  Prior to going to sleep it works fine, but after waking this happens every time.  A reboot resolves the issue, but this is incredibly aggrvating. I downloaded the drivers that were released for this WWAN from July 23rd and installed them, but even after doing so Windows is showing the installed driver as a generic device and NOT the drivers I installed(In device manager under wireless it does show as the Fibocom L850 though).  I've tried adjusting power settings, removing the card and putting it back in, uninstalling and trying a fresh install of the drivers: nothing seems to work. Has anyone encountered this or know of a potential solution?  Just about at my wits end here.

First, the 2nd SSD goes in the WWAN slot - presuming you don't have WWAN or WiGig already.  The WWAN slot doesn't support NVMe, and isn't that physical size.

mutually exclusive with WWAN and WiGig"
 
Looking at the HMM, the SSD tha would fit is 2242 SATA.
