I am a total noob with basic computer skills gathered over 40 years (Starting with a Commadore PET at School).

I am looking to reset the admin password on a Dell Latitude 5500

I have tried the website to bio-pw entering the service tag ... but it does not work .. just comes up with the "DELL HDD Serial Number" code

Does anyone have a solution that does not require reading the BIOS EEPROM chip and flashing it ?...
