How do I update my notebooks BIOS?
Posted by MySN UK on 12 July 2012 11:19 PM
Please read through these instructions fully before you start the update process. Understanding each step before you start will help you understand the procedure and to avoid potential issues.

Current BIOS versions can be found in our download area. Please note there is both an
EC and BIOS, there is a significant difference between the two. For models from 2012 onwards the BIOS now also features UEFI functionality, but is traditionally still further referred to as "BIOS". Any EC must be updated before the BIOS.

Between the EC and BIOS is the Intel Management Engine (ME). This is actually part of the BIOS. If a BIOS update also includes an ME update, a special "MESET.EXE" must be performed to prepare the ME for the update before the BIOS update.

Your current installed BIOS and EC version can be found in the BIOS setup on the main page (press F2 on laptop startup, then Main Page) .

BIOS updates to our laptops are only possible by using a bootable USB flash drive or a CD- ROM with MS-DOS. BIOS updates from within Windows are not supported, it is not possible to update the EC or BIOS through the Windows DOS Prompt.

To ensure the safety of BIOS updates, the following requirements should be met:

    Ensure that you have downloaded the correct
BIOS update for your model laptop
    Do not mix model names
(eg . XMG A504 vs . XMG P504 )
The notebook has a secure supply of power : the battery is charged , the AC adapter is connected.

Note : BIOS updates are performed at your own risk. Damage caused by failed updates are not covered by our warranty.


Download the zip files of the EC and BIOS updates for your laptop.
Create a bootable USB stick with MS-DOS. (We highly recommend using Rufus which will format your USB stick for you: - please use MBR partition scheme for BIOS or UEFI computers, all other settings as defaut)
Unzip the contents of the downloaded ZIP files each in a sub-folder on the USB stick (eg . "EC" and " BIOS") .

Implementation of EC- Update:

Restart the laptop and enter the BIOS by continuously pressing F2 immediately after the laptop restarts. If you have an SSD/PCI-e/NVMe boot drive the laptop will start loading Windows very quickly, so you need to start pressing F2 straight after the laptop restarts
Using the cursor keys in the BIOS navigate right to the "BOOT" tab and disable UEFI
    Go to the last tab on the right and select "Save Changes and EXIT"
Following the reboot, continously press F7 after the reboot - in the same way that you pressed F2 above
    In the blue boot menu, select your USB stick and then press Enter
In DOS you can type "cd" to get to the root directly, or "dir" which will list the folders onthe USB stick
    To enter the EC folder, type "cd EC"
    Run the update file by typing "ECFlash.bat" - please see above advice to read the "readme_EC" file, this will specify the command you need to type in for the flash and may differ depending on the laptop model you have
The laptop may reboot automatically, or may shut down. Again see the readme_EC.txt file for any additional instructions

Performing a BIOS update (and possible ME update):

Perform a restart and boot from your USB flash drive again, using the same method as above
This time enter the BIOS folder
optional: run MESET.EXE - the laptop will turn off automatically. Then start the laptop and boot from the USB flash drive and enter the BIOS folder again
Run the appropriate batch file from the BIOS update (e.g. flashme.bat ) and wait until the update has been successfully carried out
If the ME has also been updated , the laptop performs two automatic restarts and turns off
Remove the AC adapter and battery pack to power cycle
Restart the laptop and go back into BIOS setup
Perform a BIOS reset by loading the "Setup Defaults"
If you use Windows 8, 8.1 or 10, re-enable " UEFI " and " Secure Boot " in the " Boot" tab
Save the settings and exit the BIOS Setup

What sounds like a lot of rather complicated instructions is actually quite a short and simple process, once you understand the prodecure!

This does not mean that you need to perform BIOS updates regularly. In most cases, this is only needed to support new components (a new CPU for example) or new operating systems. If you have upgraded to Windows 10 and are experiencing problems then please check with us first as you may need to update your EC and/or BIOS.
