The T400 2768 L 35 WWAN is ready?

Hi, I bought a T400 2768 L 35 (impossible to find this serial number in the standard list, but that's what it says on the bottom plate of my laptop) my university IT shop a couple of years. I have a 3G compatible SIM card and I would use it on my laptop to surf the net. I found SIM card but did not see any WWAN card in Device Manager. Is there a way I can go online via WWAN? Or am I doomed to rely on wifi

Welcome to the community.

as long as it has not changed, this is the hardware configuration for your machine:

ThinkPad T400 (2768-L35): T9600(2.8GHz), 4 GB of RAM, HD 500 GB at 5400 RPM, LCD 14.1 in 1280 x 800, 256 MB ATI Radeon HD3470, CD-RW/DVD-RW, Intel 802.11agn, option WWAN, Bluetooth, Modem, 1 Gb Ethernet, UltraNav, Secure Chip, reader of fingerprints, camera, 4 c Li-ion, Win7 Pro 32

the key word above is option. because you do not see a device WWAN in DM, you have probably no card installed. you mention you location SIM, then you probably also have the WWAN antenna, but for sure, you can check if you are comfortable pulling the palmrest and keyboard. Please see the hardware maintenance manual here:

http://download.Lenovo.com/pccbbs/mobiles_pdf/43y6629_04.PDF / pg100-101.

If you find the sons of antennas not connected, all you need is a proper map and drivers. the important thing to consider is that the card must be on the BIOS 'white list' trusted network devices. If you scroll down to pg150 of the HMM, you will see the map in the exploded views as ex. No. 25. scroll further down to pgs273-275 who see there are 3 cards listed with their #s FRU. While you are looking to buy, be sure to get a genuine FRU role, rather than a generic/universal model.

Finally, you can get the driver of the pilot matrix, here:

HTH a little.

    Method 1: Check that all connectors (power and IDE) should be firmly fixed. Disconnect and reconnect to check.

    Method 2: As short-term solution, try to shut down the system, turn the power off, turn on the power and restart. If the device still does not work then it is probably a problem of material, the device or card/main controller card (or possibly the cable connection) will need to be replaced. If the device seems to work then this indicates a problem of software or firmware. Do not forget that the problem can recur again unless the root causes addressed.

    Method 3: Update the latest version of the device driver (if there is one).
    Check on the Web site of the vendor for a newer driver and if it is available then load it.

  • Lead time for the T400 Vista SP2 x 64 and hangs on reboot

    Hello

    I searched the forums, but couldn't find the same problem. It looks more like a problem with the OS.

    The problem is with T400 (description of model in the background) running Vista Ultimate x 64 SP2. I get huge delay before booting from the HARD disk (3-10 minutes). This happens just after the post, when it comes to a black silicone screen with the flashing line in the upper left corner, before the loading Vista appears. HARD drive may be the only boot device in the boot order, it is not serious.

    Another problem that happens on every reboot. Windows stops, goes to black screen and hangs there. I can't POST in this case. I can only-hard restart, after that, I get same start-up time huge, before the options of windows to Safe Mode shows, etc. due to improper closing (or automatically the normal startup).

    I ran all the tests of PC Doctor, the material is ok. I have updated to the latest version of the BIOS, HARD drive and firmware ODD and all the new drivers. All the patches to vista on lenovo download page appear to be part of SP2 now, because all say, they cannot be applied to the system.

    I don't want to run XP or Vista x 86, since I hold the RAM to be used at full capacity.

    Any help would be much appreciated.

    I had the same problem mentioned in the other thread you posted. I had to send mine and get the motherboard replaced.

    1 remove the hard drive from the laptop

    2. start until this stops at a few guests

    3. press on Ctrl + Alt + Delete to restart the portable computer

    If it stalls / freezes on one screen empty and does not restart then it isn't a Windows Vista problem, because the hard drive is not there, but a hardware problem which you would have to return it and get fixed.

    If it restarts right away then try to format and reinstall Vista.

    You use the 3rd party modem.
    Have you checked the modem manufacturer page if such error is already known for guys?

    To be honest I have no idea what could cause this error, but it looks like that activation of the software has failed and you need to contact the manufacturer of the software for more details.

  • Portege R600: Insert the system diskette in the drive. Press any key when ready

    I just bought a new hard drive for my R600, but after placing it I get the error:
    * Insert system disk in drive. Press a key when ready.*
    When you try to boot from it.

    In the FAQ, I think this means that the HARD drive is broken or undetectable. * However, this is not the case *, it is fresh from the store and perfectly readable with a live CD. I tried to reinstall windows, and which went perfectly, its only when it's startup time this nasty error.

    What should I do? My new SSD is an OCZ Core V2.

    To install Windows, you need the SATA drivers.
    You can set the SATA to IDE mode as Akuma said but I find that it is not a good solution. In IDE mode, you will have lost a little performance and the AHCI is faster.

    If you need to download the SATA drivers. The driver, you can find on the Web from Toshiba called Storage Manager site.
    Download the drivers and press on after having started from the CD F6 to load. For that you need an external floppy drive and if you n t have one that you can build your own installation with nLite disc.

  • Unknow new device after the bios update and to install win 7 pro to the T400

    Hi all!

    My laptop: T400 2767-2JU. After the most recent update of the bios version (3.09) and own to install all the drivers in the Lenovo Site, I found an unknown device: Simple PCI communications controller. I don't think it's Thinkpad Modem, because, before updating the bios, the system does not have it.

    Please see my picture of capture: http://i92.photobucket.com/albums/l39/hoangnhat1613/T400-UnKnowDevice.jpg

    Someone help

    PS: Sorry for my English . Where to post the link to the image? All the drivers are installed

    I've seen it suggested that this (lists of mine such as serial Port PCI) device is Intel AMT / series on local network service.  Not useful for users and some utilities normally hides.

  • How to add the partition to the T400 (Vista 64-bit)?

    I just had my T400 yesterday uninstalled all nonsense, updated and installed all my applications.  the process took several hours.  Then, I used Acronis Disk Director 10 (boot cd) to divide the C: partition into two, so that I could move my documents on a separate partition.  The separation went well, but when I rebooted, something lenovo recovery and rescue came and supposedly repaired my partition table (haha).  Well, after that I was not able to connect to windows, even when I deleted the new partition, which I did.  I had to do a reinstall factory and I am now in the process of updating all new

    You shrink the 'C' drive, and then create a new partition.
