Supervisor and Hard Disk Passwords: The supervisor password and the hard disk password (HDP) are security features that are used to protect the system and the hard disk data from unauthorized access. No overriding capability is provided. If only a hard disk password is set, obtaining permission from the password owner to unlock the password is a prerequisite for running diagnostic tests and performing service. If both supervisor password and hard disk password are set, you can enter Easy-Setup by pressing the Enter key or power-on password at the supervisor password prompt. In this case, the Password, Start up, and Initialize icons cannot be selected. See "Password Combinations (POP, HDP, PAP)" on page 451 for more information about passwords. Note: The supervisor password and hard disk password cannot be replaced If they are forgotten. If the customer forgets the supervisor password, the system board must be replaced. If the customer forgets the hard disk password, the hard disk drive must be replaced. Power Shutdown Switch: The power shutdown switch resets the system regardless of the microcode status and forces the power off. Use this push button to power-off when power is not completely off or the microcode is in a hung state. See "Rear View" on page 504 for the power shutdown switch. 414 IBM Mobile Systems HMM
