    Clevo W2xxHNx/W2xxHPx series Modded & Stock BIOS

    Notice: Make sure you have downloaded the correct Mod for your specific model and that the laptop's or a UPS battery backup is present during the update process.

    Disclaimer: I do not hold any responsibility for any problems that may occur by using the mods in a wrong way. Remember that you flash these at your own risk. I have personally tested the W25xHNx mod. Since the laptops mentioned here are of the same series and thus almost identical, you shouldn't face any problems with the rest of them. The same changes were made to all models after ensuring that their stock counterparts are identical to the tested W25xHNx laptop.

    Note: All mods contain both the Modded and Stock BIOS image files so that you can go back in case you want to. Use Mod.bat or Stock.bat at a DOS environment respectively. Check the Flashing Guide below for detailed instructions.
