Supervisor Password; How To Remove The Power-On Password - Lenovo ThinkPad Edge E545 Maintenance Manual

• 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 provide
any services to reset either the user hard disk password 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.
For instructions on how to remove the hard disk password, see "How to remove the hard disk password"
on page 38.

Supervisor password

A supervisor password protects the system information stored in the ThinkPad Setup program. The user
must enter the supervisor password in order to get access to the ThinkPad Setup program and change the
system configuration.
Attention: If the supervisor 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.
