    Hello friends

    I really need the bios for my son's computer, I do not have money to buy a new one for him

    Computer Details:

    - Lenovo E15 GEN 4
    - Serial number: PF-3YWK8S
    - TYPE NUMBER: 21E6-005FSP

    My back up bios read from the chip is corrupted because I have 3 different files, I attach you.

    I really appreciate your effort and your time.

    Thanks in advance....
