    T480s (type 20L7, 20L8) BIOS (ThinkPad) ET481 NM-B471 Rev 1.0 Schematics and BIOS

    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!
