Chapter 5. Passwords As many as three passwords may be needed for any Lenovo computer: the power-on password (POP), the hard disk password (HDP), and the administrator password. If any of these passwords has been set, a prompt for it appears on the screen whenever the computer is turned on. The computer does not start until the password is entered. Power-on password A power-on password protects the system from being powered on by an unauthorized person. The password must be entered before an operating system can be started. Hard disk password There are two kinds of hard disk passwords: • User hard disk password - for the user • Master hard disk password - for the system administrator, who can use it to get access to the hard disk even if the user has changed the user hard disk password Note: There are two modes for the hard disk password: User only and Master + User. The Master + User mode requires two hard disk passwords; the system administrator enters both in the same operation. The system administrator then provides the user hard disk password to the system user. Attention: If the user hard disk password has been forgotten, check whether a master hard disk password has been set. If it has, it can be used for access to the hard disk drive. If no master hard disk password is available, neither Lenovo nor Lenovo authorized service technicians provide any services to reset either the user or the master hard disk password, or to recover data from the hard disk drive. The hard disk drive can be replaced for a scheduled fee. Administrator password Administrator password controls the access of the whole setup utility. Only Administrator password was set then User password can be set. If Administrator password was cleared, the User password was cleared too. Attention: If the administrator password has been forgotten and cannot be made available to the service technician, there is no service procedure to reset the password. The system board must be replaced for a scheduled fee. © Copyright Lenovo 2014 27
