If you have a Dell computer, either a laptop or a desktop, the password can be calculated but you need to find your service tag. This service tag is usually displayed on the screen of the locked out Dell computer.

Dell BIOS Service Tags

The BIOS service tags for Dell computers have the pattern of 7 characters with a 4-character suffix. Example of service tag for a Dell BIOS:

  • QZ6X56H-595B
  • 1234567-D35B
  • 2345678-A95B

Where can I locate such code? Simply enter a wrong password in the BIOS login prompt, make three (3) failed login attempts and you shall see the lock code and the service tag of your Dell computer.
