For models supporting the Passphrase function, press F1 while HDP icon is appearing on the screen; then enter the master HDP. For the other models, enter the master HDP.

Note: To check whether the ThinkPad computer supports the Passphrase function, enter BIOS Setup Utility and go to Security --> Password. If Using Passphrase item is displayed in the menu, this function is available on the ThinkPad computer.

2.Click Access BIOS. The system Restart Required window is displayed.

3.Click Yes. The computer restarts, and the BIOS Setup Utility screen opens.
