Passwords

As many as three passwords might be needed for any ThinkPad notebook computer: the power-on password, the hard-disk password, and the supervisor 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.

Note: If only the supervisor password is set, the password prompt does not appear when the operating system is booted.

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 booted. For how to remove the power-on password, see “How to remove the power-on password” on page 34.

Hard-disk password

There are two 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 a master hard-disk password has been set, it can be used to access the hard disk drive. If no master hard-disk password is available, neither Lenovo nor Lenovo authorized service technicians
