    I don't believe you can. The installer does a version check to make sure the BIOS is correct for your motherboard and newer (or the same as) the currently installed version. I don't know of any way around that.

    Good afternoon miljkocv97 !

    Bios downgrade procedures are extremely risky and may render the equipment unusable and void the warranty on the device.

    I don't know how to go back to the previous version because when I bought it it was 2.13 and yesterday I upgraded to 2.17

    Regardless, do you know how to return to factory bios 2.13? Nice day

    Then what should i do?  I noticed with this new bios, fan cooling is often ignited and the temperature is higher.

    So far no such situation has been reported on other laptops with this version of Bios.
    In this case, you should contact Acer in your area directly.

    Can you send me contact from Acer directly ?
  • After uefi bios has been updated, it is recommended to press f9 to restore it and then f10 to save on exit. This may fix some bugs from the previous version.
