Hardware controlled passwords
Use the Setup Utility program to set the hardware controlled passwords. For more
information about passwords, see “Using passwords” on page 49.
Operating system password
Note: This section applies only to computer models that have an operating system
preinstalled from Lenovo.
An operating system password is very similar to a power-on password and denies
access to the computer by an unauthorized user when the password is activated.
The computer is unusable until the correct password is entered and recognized by
the computer.
Vital Product Data
Each computer has a unique Vital Product Data (VPD) code stored in the
nonvolatile memory on the system board. After you replace the system board, the
VPD must be updated. To update the VPD, see “Updating (flashing) BIOS from a
disc” on page 746.
Secure Managed Client
The Secure Managed Client (SMC) is a storage-based, desktop computing solution
that helps businesses reduce IT costs and improve security by turning off hard disk
drives and storing all data in a non-server remote location while offering users the
flexibility and performance of a traditional desktop computer. For computer
models that do not have an internal hard disk drive and a preinstalled operating
system, but use a remote hard disk drive accessed through the SMC - Storage
Array, contact the network or storage administrator.
BIOS levels
An incorrect level of BIOS can cause false errors and unnecessary FRU
replacement. Use the following information to determine the current level of BIOS
installed in the computer, the latest BIOS available for the computer, and where to
obtain the latest level of BIOS.
v
To determine the current level of BIOS:
– Start the Setup Utility.
– See
BIOS Revision Level on the Main setup screen.
