Contact Dell for Password release code

On contacting Dell Support you will be asked to confirm the below for security reasons:

Note: If your warranty has expired you may be charged for technical support assistance.

  • Ownership of the computer.
  • Whether you are authorized to clear the password on the system.
  • Contact Information.

Please have the full error message along with your system Service Tag information as this is required to create the release code.

Note: You may also be prompted to e-mail or fax the above information to the support team department along with company signature or equivalent proof of ownership.

Clearing Password

Once Dell Support has provided the master password, you will enter this at the prompt and then press Ctrl + Enter to complete the process. The master hard drive password will automatically clear the hard drive password.

Note: The master Password will be case sensitive so please check that Caps Lock is not enabled.

If the computer responds with the message Invalid Password, press the Enter key and continue to enter the same password three more times. After the fourth attempt the BIOS should accept the master password, clear the password, and allow access to the hard drive.

Note: If the password still does not work, check that Num Lock and Caps Lock are not engaged on the keyboard, and swap with a known-good keyboard, if available. If the known-good keyboard works, replace the Keyboard. If a known-good keyboard does not work, or is not available, replace the Hard Drive.

If you require further assistance, please contact Technical Support

Interesting fact
Registered nurses may specialize in helping patients with certain diseases, such as diabetes, or work in certain conditions (in the operating room, resuscitation or caring for the seriously ill), specialize in the care for certain patients (for example, in the neonatal ward or separation of elderly patients). All these specializations require relevant and up-to-date knowledge, so almost every state requires licensed nurses to pass special educational program - lpn continuing education courses.
