MC7750 Lenovo Gobi 4000

I bought a Lenovo Gobi 4000 MC7750 (Lenovo P/N 0B 42409 FRU PN 04W3791)

The device is labeled "Sierra Wireless | Process ".
She throws 4 devices in Device Manager.
Are hardware ID: Vid_114f & Pid_68a2 & MI_00/02/03/08
I tried to install the driver, it seems no matter what I do
Since it is a Lenovo brand card and there will seem to have a knack for doing things to work when they are not supposed to I thought I could post it here and see if you have any suggestions.

Thank you

1. even once, mc7750 does not work in Etisalat LTE network. Even if the drivers will install correctly with the Etisalat sim card you won't see and do nothing.
2. what elements related to the mc7750 do you see not in Device Manager? Who is the exclamation point?
3. what operating system is installed on your laptop? that you install the drivers?
4. is the large map mobile broadband enabled in the window of control Fn + F5? Lenovo access connections is installed?

  • Compatibility of Gobi 4000 for W520 CTO

    Hi all

    I wish you all Merry Christmas!

    My question is quite simple.

    Is the desert of Gobi 4000 W520-compatible or not? If this is not the case, why is this? I know that the desert of Gobi 3000 is for the W520 Lenovo, but it seems that it does not support 4G LTE via the mobile network of the carrier, and that's why I want to buy the desert of Gobi 4000.

    Hi again, fasdf78

    The driver that you found supports the two Gobi 3000 and 4000, but your machine itself does not support the desert of Gobi 4000 because of your BIOS whitelist. I can certainly understand your confusion, especially since this driver works for several cards. It is a driver of Lenovo activation that activates the capabilites broadband mobile system, so it supports multiple cards and machines, even if machines and cards are not compatible between them, as in your case. To summarize: the desert of Gobi 4000 is unfortunately not compatible with this unit.

    It will be useful,

  • Gobi 4000 in W530 - 1802 error

    Hello!

    I just got my W530 by UPS yesterday, he opened and put in my Gobi 4000 Verizon card I also got Lenovo as advised by the rep that helped me to order.

    When I turned on the laptop, I got an error that says "1802 - unauthorized network is connected."

    Google has turned up that these mistakes happened when you use non-Lenovo/IBM cards, but my card is purchased directly from Lenovo on the same order as my laptop.

    I also got an extended warranty on this computer, so I don't want to cancel that.

    What should I do?

    Thanks in advance.

    To clarify, I got the W530 broadband "extensible" (because the desert of Gobi 4000 wasn't available preinstalled) and bought the desert of Gobi here: http://shop.lenovo.com/us/itemdetails/0A36318/460/5166FF91DAB5442C846A84A5FA006F9D

    USB3.0 appears but does not seem to settle (it appears in the paper thininstaller candidate list).

    then I read that on the RapidBoot shield, update notes that usb 3.0 needs rapidboot v1.23 pilots (who does not appear on the new driver releases page):

    Sorry for these questions, updates team still working on getting all the updates that are released for new systems like X 230...

    Bluetooth must be here today.

    I do not recommend installation RapidBoot shield unless you have personally tested and determined that it makes your boot faster image and does not cause side effects.

    Intel USB 3.0 has addictive bad RapidBoot shield, the team working on the removal of the dependence.  If you use ThinInstaller, you can find a way to remove the dependency from the XML yourself.

  • x 120 mobile broadband e

    Hello

    I recently bought a laptop X120e. I see that it has a slot for SIM card to the breast. Also some drivers were planned on the site of support Lenovo Gobi 2000/3000 / Ericsson/Huwawei 3 G modules.

    This laptop comes pre-assembled with one of these data cards? Or does have to buy one separately?

    Kind regards

    is not higher unless you specifically bought a laptop that comes with the pre-installed WWAN card.

  • B550 and 3G modem

    I've got B550A without 3 G modem. I called technical support according to this feature. They said that Lenovo provides a cellphone with 3G modem (except netbook) in Russia. I can buy the modem 3G Lenovo GOBI 2000 but technical support could not answer all work OK.

    Everyone settles this modem in laptop? Correct laptop she leans on this modem? What kind of trouble were with her?

    Thank you in advance.

    F3507g is compatible with lenovo thinkpad series but not sure with lenovo ideapad series.

    I suggest to consult your manual for more information or call support line.

    but I suggest you use 3 g usb due cards wwan modems may have some problems with the bios.

    Therefore, to better communicate with your mobile operator.

    Please, after return of your decision.

    If you continue to insist to use wwan, I'll try to find an answer for you to choose what wwan, you can use.

  • E120 Lenovo Edge - cannot detect the WAN of GOBI 2000 map

    Hi, I hope someone could help.  I bought an E120 that my country does not see the X120e

    I bought a card WWAN of GOBI 2000 dealer of Lenovo.  The card passes through the white list very well although it is not mentioned as one of the taken WWAN devices supported.

    I tried to install the 7xwc48ww.exe (drivers X120e and Edge 11 WAN) to see if it would work.  The GOBI loader installs, but the driver does not load, sense - in device - PORTS - Gobi charger Manager

    -In device - network adapters - No. Gobi WAN Card Manager

    I also tried the solution-http://curiouslynerdy.com/2009/05/qualcomm-gobi-wwan-card-on-windows-7/ , but still no joy.

    According to me, the X 120 and E120 are very similar, so I guess the Gobi WAN should be able to work.

    Can anyone suggest an alternative?

    Thank you very much!

    The E120 Edge is like the X121e GOBI 3000 or F5521gw will work. I tried a GOBI 2000 in my E120 with the same result as you.

    Nice day.

    Looking at the specs in the PSREF: http://www.lenovo.com/psref/pdf/lttcwbook.pdf

    Intel HD Graphics 4000 in processor,
    supports an external digital monitor via HDMI Mini and Mini DisplayPort;
    supports two independent screens;
    Maximum external resolution: 2560 x 1600 (Mini DisplayPort) @60 Hz;
    1920 x 1200 (Mini HDMI) @60 Hz

    seems the best you can get with the graphics card integrated is WQXGA through CDM.

    Hope this helps to clarify.

    Kind regards.

    Hello world! I just bought a new laptop of Lenovo Y580 leave the Lenovo Web site. It was delivered to my house and there is no problem. I opened it to the top, and everything was great!

  • Other drivers for 2014 X 1 carbon GOBI 5000?

    I noticed a few other discussions about the card WWAN 5000 GOBI on 2014 X 1 carbon machines, so I know that I'm not the only one with questions... I have two new X1s (two 20A 7), one with a GOBI Verizon 5000 and another with a GOBI AT & T 5000. The Verizon card installs very well and is working, no problem there. AT & T has in turn map: not presented all the Device Manager, presented as an 'unknown' object and now after uninstalling the driver, in removing the card, restart, re-install the card, etc., the driver package installs successfully, but the map appears under ports such as COM4. The description is correct - system sees it as a «Sierra Wireless EM7355...» ». Of course, Mobile Broadband Activation does not see the card and therefore will not work.

    In another thread, someone suggested they could get their hands on an older driver package that has been installed successfully. hope to get a link? Or, better yet, a update driver current?

    welch_pm,

    follow the page below:
    http://support.Lenovo.com/en_US/detail.page?docid=HT081505

    This is the activation of Gobi 5000 at Verizon Wireless, but there is a chance the reason for your problem is the same - it is necessary to change some parameters of internal modem. Make sure that the values of DAFAULTIMAGE is 2, USBCOMP is 14

  • Lenovo y480 d3d9/d3d errors

    Hello. I posted this question in several other forums on the internet, but nobody seems to have an answer for me, so I thought I'd try here. My Lenovo y480 was having serious problems playing some of my steam games recently, such as Storm Rising, chivalry: Medieval Warfare, rusty, Sins of a Solar Empire and others. My laptop has the 650 gt, which comes with an Intel HD 4000 in a framework of Optimus, and whenever I try to play one of these games I have one of several possible errors. Either the game will run in windowed mode of low resolution, which crash and will give an error message on a d3d9 or d3d error, sometimes accompanied by a black or white screen flashing, if I put it at the highest resolution (1366 x 768) or if I put it in mode full screen. This happens with rust and chivalry. With storm rising, the game immediately crashes and gives an error d3d (impossible to create the d3d device) on a white screen. I tried to change the resolution by default in the configuration files of games to my standard resolution, so to update my drivers and directx. However, nothing has been able to solve these problems. Can anyone possibly tell me what is the cause and how to fix it? Any help is appreciated, thanks.

    Thanks for the help! I followed your advice and looked for older drivers, and in the process, I noticed that there are several newer drivers me had not prepared my GeForce experience. I downloaded the latest drivers and a newer version of GeForce experience, and it fixed all the questions I had. I certainly would have thought to update manually the drivers beforehand. Thank you!
