Passwords
As many as four passwords may be needed for any ThinkPad notebook computer: the power-on password,
the hard disk password, the supervisor password, and the system management password.
If any of these passwords has been set, a prompt for it will be displayed on the screen whenever the
computer is turned on. The computer does not start until the password is entered.
Note: If only a supervisor password is set, the password prompt will not be displayed when the operating
system is started.
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. For instructions on how to remove the
power-on password, see "How to remove the power-on password" on page 32.
Nvme password
There are two kinds of Nvme passwords:
• Single password - for the user
• Dual Password (User + Admin) - for the system administrator, who can use it to access any storage
drive in a system or any computer connected in the same network even if the user has changed the user
Nvme password
Note: The Dual Password (User + Admin) mode requires two Nvme passwords (user Nvme password +
admin Nvme password); the system administrator enters both in the same operation. The system
administrator then provides the user Nvme password to the system user.
