Updating EFI BIOS & EC

    Important notes!
    Please read the following instructions carefully. If you follow all steps exactly as described, an EC / BIOS update is fast, easy and safe. If you have any questions or if you still feel unsure, please contact us!

    1. We cannot accept any liability for a failed EC or BIOS update! If problems occur during or after the EC- or BIOS update, we cannot repair your device under warranty. Therefore, follow all steps and instructions exactly as described!

    2. Please make sure to use the correct BIOS-/EC-files for your notebook, otherwise you can damage your notebook irreparably.

    3. Please note: If the downloaded folder contains a README.txt and/or LIESMICH.txt, then the information written there must be noted! If the downloaded folder does not contain either of these files, then the steps shown in this guide apply.

    4. Make sure that your notebook is connected to the mains and that the battery is charged to at least 30%. Interrupting the power supply during the update process may cause irreparable damage to your device.

    5. Please reset your BIOS to default values in advance.


    Why an EC update?


    The embedded controller (EC for short) is a small hardware component, a so-called "microcontroller", which is installed in notebooks and performs various basic control tasks within the computer.

    These control tasks include receiving signals from the keyboard, charging the battery or controlling the fans.

    At TUXEDO we customize these control tasks in the EC so that your notebook can communicate in the best possible way with our drivers and the TUXEDO Control Center.

    Therefore, we recommend that you perform an EC update, when available. You can see if there is an update for your specific model in your user account under "Downloads for your TUXEDO". In our newsletter we also inform our customers regularly about available BIOS and EC updates.



    Why an BIOS update?


    The Basic Input/Output System (short: BIOS) or correctly expressed (U)EFI (Unified Extensible Firmware Interface) is the firmware of a notebook or PC, which is executed directly after switching on the computer and takes over the basic initialization of the hardware. For basic, hardware-related improvements or bug fixes, an update of this EFI / BIOS firmware is therefore necessary in some cases.



    How to execute an EC update / BIOS update


    Step 1: Create an EC / BIOS USB stick


    The process for updating the ECs and the BIOS are largely identical.


    Download in your user account under "Downloads for your TUXEDO" the correct EC package / BIOS package suitable for your device via the "Download" button and unpack the downloaded file to an empty USB stick with a FAT32 file system.

    If both an EC and BIOS update are available for your model, you can also download both updates and unzip them to your stick.

    Next, download the EFI Launcher package and extract its content to your USB stick.


    The following data should now be on your USB stick:

    • A folder named after your downloaded EC file or BIOS file, or two folders if you downloaded EC update and BIOS update.
      (Please note: You cannot update EC and BIOS in the same pass. Run the EC update first and then run the BIOS update again with this guide.)  
    • A directory named 'EFI'
    • The file 'Shellx64.efi'
    • The file 'startup.nsh'

    Please note! If you have a significant older  TUXEDO device, please check if there is at least one .nsh file in your downloaded EC- or BIOS update directory! If NOT, please follow these instructions.


    Step 2: Boot your TUXEDO from your USB stick


    Make sure again that your TUXEDO notebook is connected to the original power supply (no USB-C power supply) and battery and plug in the USB stick into a free USB port. Switch on your TUXEDO.

    Immediately after turning on the device, press the F7 key quickly and repeatedly until the boot menu appears. (Depending on your TUXEDO model, the boot menu may look different. You can see two examples below).

    If you missed the timing and your device boots into the operating system instead, just shut down your TUXEDO again. After a few seconds, turn your notebook back on and try again.

    If the boot menu appears on the screen, use the arrow keys to navigate to the entry of your USB stick (in our examples these are 'UEFI General UDisk 5.00' and 'EFI USB Device' respectively) and press the Enter key.


    Step 3: Execute the update via the EFI shell


    Now the so-called EFI shell is getting started. You now have to navigate to the EC or BIOS update file and execute it. All necessary information is described in the following picture.


    So type the command dir (for "directory") and press Enter. The content of your USB stick will now be listed.

    Now type cd (for "choose directory") followed by a blank space and the name of your EC or BIOS folder (so the command is: cd folder name).
    This will take you to the folder on your USB stick that contains the file to run the EC or BIOS update.


    Short intermediate step: Please check in advance if there is a file called "MeSet.efi" located in your BIOS update folder.
    If not, you can skip this intermediate step.
    If yes, please execute this file now by typing the file name (so in this case e.g. MeSet.efi) and confirm with Enter. This command enables the write permission for the BIOS (a kind of security measure from Intel), so that you can install the BIOS update afterwards. MeSet.efi will restart the notebook, so everything's okay.


    You are in your EC / BIOS update folder. Depending on your notebook model, there are different numbers of files in this folder. We are only interested in one specific .nsh file, which - depending on the notebook model - is called F.nsh, Flash.nsh, Flashme.nsh or ECFlash.nsh.

    Have you found a file with this name? Then type in this file name (in our example below it is the EcFlash.NSH (upper/lower case can be ignored)) and press the Enter key.


    Step 4: You did it!


    The update process will now start and automatically delete the old EC or BIOS files from your notebook and install the new version.

    Then restart your TUXEDO and the EC or BIOS update is done!


    (Step 5: Change BIOS boot priority)


    With some TUXEDO models it can happen that your USB stick is at the top of the boot order after a BIOS update. That means your TUXEDO may reboot after the update and then automatically boot from your USB stick and start the EFI shell again. If this happens, don't worry!

    As long as the EFI shell is just started, but the EC or BIOS update process, as described in step 3, has not yet been started manually by you, you can still safely turn off your device. Simply press the power button for a few seconds until the notebook turns off.

    Remove the USB stick from your TUXEDO and restart your device. Immediately and repeatedly press the key quickly to enter the BIOS (depending on the model this is F2 or ESC) and navigate to the "Boot" section in the BIOS. There you can change the boot order (Boot Option or Priority) to your internal system drive and exit the BIOS via the option "Save Changes and Reset" or similar.
