Supervisor Password - ThinkPad S440 User Manual

Tips on using the hard disk passwords
• You can set the minimum length of a hard disk password through the Security menu.
• If you set a hard disk password of over seven characters, the hard disk drive can be used only with a
computer that can recognize a hard disk password of over seven characters. If you then install the
hard disk drive in a computer that cannot recognize a hard disk password that contains more than
seven characters, you cannot access the drive.
• Record your password and store it in a safe place. If you forget the user hard disk password, or both user
and master hard disk passwords, Lenovo cannot reset your passwords or recover data from the hard disk
drive. You must take your computer to a Lenovo reseller or a marketing representative to have the hard
disk drive replaced. Proof of purchase is required, and a fee will be charged for parts and service.

Supervisor password

The supervisor password protects the system information stored in the ThinkPad Setup program. If you have
set a supervisor password, no one can change the configuration of the computer without the password. It
provides the following security features:
• If only a supervisor password is set, a password prompt is displayed when you try to start the ThinkPad
Setup program. Unauthorized users cannot access the ThinkPad Setup program without the password.
• The system administrator can use the supervisor password to access a computer even if the user of that
computer has set a power-on password. The supervisor password overrides the power-on password.
• If both a supervisor password and a power-on password are set, you can do the following only if you
have the supervisor password:
– Changing or deleting the power-on password
– Changing or deleting the supervisor password
– Changing date and time
– Specifying the minimum length for power-on password and hard disk password
– Changing the setting for the security chip
– Erasing the fingerprint data
– Enabling or disabling the following features:
– Wake on LAN and Flash over LAN
– Lock UEFI BIOS Settings
– Password at unattended boot
– Boot Device List F12 Option
– Boot Order Lock
– Flash BIOS Updating by End-Users
– Internal network device
– Internal wireless device
– Internal Bluetooth device
– Internal Network Option ROM
Notes:
• The system administrator can set the same supervisor password on many ThinkPad notebook computers
to make administration easier.
• When Lock UEFI BIOS Settings option is enabled, all BIOS settings cannot be changed. To change
the settings, a supervisor password is required.
