    Hi,

    I want to flash T480s BIOS for model 20L8. I want to delete supervisor password.
    Currently I have N22ET56W (1.33) and firmware 11.8.65.3590.
    Can you help me? Is it safe to flash and are all data (serial no, etc.) preserved?
    Also, after flash, can I safely update the BIOS?

    Thank you!

    You must also see your technique, I only provide a solution, can not check directly. We have tested many models

    So, what happened? Did you find the documentation?
