RE: Latitude 7480 Administrator BIOS password reset
Thank you for your message.
If the set password hasn't worked, we will need to use the master password.
Please click on my Dell username & send a private message with the service tag, registered name & email address.
Once we confirm the ownership details, we will be able to request for the master password.
