This, "BIOS fails due to password", is under investigation. Installing a PC BIOS update from a USB thumb drive is the safest process. How to flash the BIOS on a Dell Desktop or Notebook with a USB thumb drive I do not install a PC BIOS update "through" any software (Dell Update Application, SupportAssist, Windows Updates, etc.). IF I install a BIOS update, it is via the above F12--> OTHER OPTIONS --> BIOS Flash Update.
I was trying to update the BIOS through Dell Update on my Dell G3 3579 laptop and got the same exact error. It's my personal computer and I'm the only one with access to it. I'm not sure what password does the error refers to, but there must be a mistake because I haven't modified any of the BIOS settings manually. My device runs Windows 10 22H2 update, and the current BIOS version is 1.22.0 (AUG 2022).I was trying to get the latest version 1.23.0
