T480 hibernation breaks WWAN L850-GL

Q: T480 hibernation breaks WWAN L850-GL

Hi! I have a new T480 with the factory installed WWAN option. It works on a fresh startup, but when the laptop goes into hibernate mode (not sleep) and then I wake it up, the WWAN stops workding. Windows Device Manager shows it as "Windows has stopped this device because it has reported problems. (Code 43)" Why does this factory installed option not work correctly in normal use? I would prefer not to have to disable hibernate or have to restart the laptop every time I want to have working WWAN. Thanks for any advice!

Preferred Solution: T480 hibernation breaks WWAN L850-GL

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.)


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.

Until yesterday, the Fibocom L850-GL worked perfectly in my T480. After a restart, the device was gone and instead the error message "Detected unrecognized USB driver" appears permanently three times in the system log. The device manager recognizes a USB-Com device instead of the Fibocom. Detected unrecognized USB driver (\Driver\pci).Detected unrecognized USB driver (\Driver\ACPI).Detected unrecognized USB driver (\Driver\UDE). Even after a clean Windows 10 Pro (1803) installation, the error is repeated.The original installation of Windows 10 Pro (1803) immediately detected and installed the Fibocom.BIOS is up to date. For now I deactivated the device. Any hint?

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.

 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. 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 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?

Hello, I own a 7th Gen Thinkpad X1 Carbon.  Everything was great until yesterday, when my Fibocom L850-GL WWAN / LTE began to repeatedly disconnect and reconnect (causing the Windows 10 noises for connecting and disconnecting hardware to occur nonstop).  I have a US T-Mobile SIM card in the SIM tray. When you look on device manager, the Fibocom L850-GL will literally continually disappear and reappear, strangely with settings intact.  During the times it is connected I switched "Selective Suspend" to "disabled" and unchecked "Allow the computer to turn this device off to save power" in "Power Management."  These setting evidently remain intact when I check them.  Drivers are the latest offered by Lenovo.  I've disabled, uninstalled, reinstalled, applied latest drivers, and still have the same issues.  Can anyone advise? Thanks   Log Name:      Microsoft-Windows-Kernel-PnP/ConfigurationSource:        Microsoft-Windows-Kernel-PnPDate:          12/10/2019 12:25:47 AMEvent ID:      411Task Category: NoneLevel:         ErrorKeywords:      User:          SYSTEMComputer:      ThinkpadDescription:Device USB\VID_8087&PID_0AC9&MI_00\7&4fa60...

I have a T480 with a Fibocom L850-GL WAN card. Frequently, but all the time, when waking up from sleep, it fails to appear in my Wireless options, and when I look at it in the device manager, under Device status Windows gives the message "Windows has stopped this device because it has reported problems. (Code 43)" I see others have had some problems with this card, but I haven't found this specific issue. I've installed the latest drivers as of today (2018-07-28) but I'm still having this problem. If I manually disable and re-enable the device it always comes back, but it's pretty annoying to have to do that.  Before I contact Lenovo for repair (the laptop is only a couple of weeks old) I wanted to check the forum for any ideas. Thanks!

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, I've owned a T480 for a while now, and would like to add a WWAN card to it. I've considered USB modules but can't find any that will accomodate my providor so I am investigating the possibility of adding an internal one. I see that the T480 has the slot for one inside, and a place for the sim card behind the battery, but I don't see any antenna wires, and so I'm wondering if this is actually possible and if anyone knows how to do it, or has done it. There seems to be very little information online about adding mobile broadband cards in general. I had quite a time tracking down the Sierra Wireless AirPrime module that is supposed to fit my thinkpad module. Any information on the subject would be greatly appreciated. Thank you.

Hello and welcome,
That's not something I've done (or care to do if the antennas aren't in place) but these links may get you started.  Looks like the antennas are part of a WLAN WWAN combo.

Hi guys,

I'm new here, and I have a problem that I have searched very extensively for. I have a Toshiba Tecra A4-S211 laptop, running Windows XP Pro SP2, and with an Intel ProSet 2200BG internal wireless card installed.

My problem is that when I'm connected to a wireless network (my Belkin wireless router), all works just fine until I hibernate or go into standby. When I resume Windows and everything loads up again, the connection appears to be working fine -- that is, it will say "Status: Connected" in the tray, and the signal strength seems fine. However, when I try to get online, nothing works. What's much more confusing is I can no longer ping the router or any other computers on my network. I can ping my IP assigned via DHCP, but I can no longer get online or even ping the router itself, even though it shows an excellent connection.

I've tried a number of different things in attempting to fix the problem. Rebooting always fixes it, but so far I can't find anything, short of restarting, that will.

I repaired the connection, which seems to go through all of the steps successfully, including renewing the IP address.

I tried

ipconfig /flushdns
ipconfig /release *
ipconfig /renew *
All of these complete successfully, yet I still can't communicate with the router or beyond.

I tried disabling/enabling the wireless connection, I disabled the adapter in Device Manager, and I also physically turned... Read more

Hi everyone, I'm a student and planning to buy the Campus version of the Thinkpad T480s with the Nvidia chip. It doesn't come with a WWAN module, but I'd like to add one. Information on that topic seems sparse and I tried to look for M.2 slot WWAN modules at different online stores. I found a few ones, namely- Huawei ME906S, listed to be compatible with 2016 Thinkpads- Sierra EM7455, listed to be compatible with the *70 series Thinkpads- Fibocom L831-EA (Intel XMM 7160), listed to be compatible with *70 series Thinkpads According to this reddit, at least the Huawei and Sierra ones are incompatible unauthorized for a T480s which, if true, is simply inconvenient, annoying and disappointing. As I mentioned above, buying a Thinkpad with a pre-installed LTE module is not an option because I'd like to have the Nvidia chip and am buying a Lenovo Campus Thinkpad which comes at a reduced price (and in Germany, it's the only way to get one with an Nvidia chip). As the Lenovo configurator and the T480s platform specifications indicate, the Fibocom L830-EB (Intel XMM 7262) and Fibocom L850-GL (Intel XMM 7360) are officially used and should definitely be compatible. However, I can't find them anywhere except pre-configured with a Thinkpad, which is not an option for me. Can anyone please help me with either of the following:- Is the Fibocom L831-EA (Intel XMM 7160) authorized for and compatible with the T480s?- Is there any place where I can get a Fibocom L83...

I've had this problem for a long time. When I put my computer in hibernation, sometimes when I wake it, it hangs at the user select screen, or it just shows a black screen. Sometimes I can reset the computer after it has hanged, and try again resuming from hibernation, and many times it will work after a couple of tries. Other times after resetting I won't get the prompt to try again with resuming (the other option is to delete hibernation data and reboot the system) but I will get the usual screen that says that Windows was not shut down correctly (with all the options for safe mode, etc). If I cannot resume and I get the screen with safe mode and all the other crap, I finally log in I get a notice that there was a critical error, in the details I see BlueScreen and other data, but I actually never get a blue screen. In the dump folder, there are no dmp files related to the hibernation hanging.

Anyway, when it happens, I see several Event 18 WHEA-Logger in the event viewer, about 6 of them every time.

What's weird though, is that I literally have NO problems with this computer other than this. The only times it hangs is when I resume it from hibernation. I can play games or run stress tests with or without overclock and the system is 100% stable. But there is some problem that prevents it from resuming from hibernation correctly, so every time I use it is basically a gamble because it has like 50% chance of working.

I have encountered this a few times and I thought of collating past experiences of other users on their successful attempt to restore the eco friendly hibernation feature. I personally favour hibernate than sleep as sleep slowly bleeds your battery away.

I just installed a 512GB M4 Crucial SSD into my laptop.

For my case, it happens when I tried to resize the C: partition to a smaller size using a third party software called minitool partition wizard. Windows native disk management somehow restricts the minimum size for C even though I have like 80GBs of free space. After successfully resizing it using partition wizard, i lost hibernation feature.

After searching the internet for solutions, many suggested powercfg cmd but this didnt work for me. I have also tried other recommendations and those didnt work too.

Since hibernation needs to store the OS states and apps into a file before shutting down, I suspected the pagefile.sys got corrupted due to the resizing and did a chkdsk with fix. It found some errors and fixed it. After a successful chkdsk fix, I got back hibernation feature! I also recommend to leave the vritual memory to system managed as I read from other posts that hibernate needs about 4GB of pagefile to hibernate.

Hope this helps others who have similar problems. On the hand if you have successfully restore your hibernation feature, please post your experience here. Thanks!

Hi Geminy,
let's make sure that you:

1) replaced the broken hard drive for a new one that is working fine

2) tried to install Ubuntu linux using your DVD optical drive, and installation were successful (or you just tried to start system from live-dvd and not finished installation to HDD)?

3) put the Windows installation media in your DVD-drive and – what happens? It will not boot from the DVD-disk, it will not start installing windows, it does not see the HDD drive and says there is no place for install… Does the windows installer raport any problems? Do you see any messages? Does it restart by itself?
Which version of windows you try to install? Is it the same version you had on your laptop before the HDD crashed?

Is the new hard disk mechanical hard-drive or electronic SSD type?

Possible problems are with: the BIOS settings (UEFI / CSM mode, secure boot option and so on), with HDD/SATA drivers (AHCI / compatibility…) or maybe simply you have installed Ubuntu on hard drive and now windows has no space to fit there, nor it sees any space as it is XFS/EXT4 formatted by linux. There are also many other possibilities, so please give as many information as you can.

A:BSOD on Satellite L850


All drivers for your notebook model you can find on http://www.toshibamea.com/en/Download-Files

Your PSKG8V model is listed there. Maybe it sound stupid now but I don't know what the ?power driver? is. If your notebook was delivered with original preinstalled OS I recommend you to set BIOS to default settings and install original recovery image.
After doing this you can test functionality with ?factory settings?.

Post some feedback please.

Model Satellite L850-Y3110(PSKFWG-00F00C)
my laptop specs are i73630QM with 8gb DDR3 Ramand Raedon HD7670M 2Gb graphics in 64 bit Windows 10 pro.When i purchased it was installed with Win8.1 afterwards i manuallyt upgraded it to Win10.Everything was fine graphics is also ok.

From toshiba's website i found that my laptop is not up-gradable to Windows10. Anyway i have upgraded and there is no going back.
So my drivers are now auto updated with windows.

But to find drivers from my OEM's website i checked all toshiba's websites.But most of them does not recognize my model except this website.
In this site also i am not getting any drivers of Windows8.1.Only drivers of Windows 7 is available.

1)I would like to know where i can get these drivers.(Win 8.1)?

Please check with my model number before replying because i have spent many days for this.Again toshiba-india website provides only bios update drivers for my version.
2)So i would like to know whether other L850 model's drivers are compatible with my lap?

Now i will come to actual problem.
From intel's website i am aware that my laptop is having inbuilt graphics intel HD4000.
3)So where is it?
But nowhere in my laptop i can see this display adaptor.I looked into bios also to see whether it is disabled in bios.
And i found that there is no tab in bios regarding display/graphics.

I tried all latest drivers from intel for HD4000 and drivers from AMD for Redon7670M.
Everytime intel's setup driver installation fails.Add de... Read more

Please help if you can.

A:Satellite Pro L850-1EF does not power up

First of all a good news: your personal files on the HDD like pictures, photos should not be affected.

You could get access to the files removing the HDD from the notebook (details here: http://aps2.toshiba-tro.de/kb0/CRU2603C20000R01.htm) and connecting this HDD to another computer using an USB-SATA 2.5” enclosure.

Now bad news: from my point of few your notebook developed an serious hardware malfunction; maybe its just an RAM module problem… in such case you would need to replace only the RAM modules but in worst case the motherboard could be faulty and such fix could be very expensive procedure.
