Windows label

Your computer might have a Windows 10 Genuine Microsoft label affixed to its cover depending on the
following factors:

• Your geographic location

• Edition of Windows 10 that is preinstalled

Go to

https://www.microsoft.com/en-us/howtotell/Hardware.aspx for illustrations of the various types of

Genuine Microsoft labels.

• In the People’s Republic of China, the Genuine Microsoft label is required on all computer models
preinstalled with any version of Windows 10.

• In other countries and regions, the Genuine Microsoft label is required only on computer models licensed
for Windows 10 Pro.

The absence of a Genuine Microsoft label does not indicate that the preinstalled Windows version is not
genuine. For details on how to tell whether your preinstalled Windows product is genuine, refer to the
information provided by Microsoft at

https://www.microsoft.com/en-us/howtotell/default.aspx.

There are no external, visual indicators of the Product ID or Windows version for which the computer is
licensed. Instead, the Product ID is recorded in the computer firmware. Whenever a Windows 10 product is
installed, the installation program checks the computer firmware for a valid, matching Product ID to complete
the activation.

In some cases, an earlier Windows version might be preinstalled under the terms of the Windows 10 Pro
license downgrade rights.

Use passwords

This section introduces types of passwords in UEFI (Unified Extensible Firmware Interface) BIOS (Basic
Input/Output System) and how to set, change, and remove a password.

Password types

You can set a power-on password, supervisor password, system management password, or hard disk
password in UEFI BIOS to prevent unauthorized access to your computer. However, you are not prompted to
enter any UEFI BIOS password when your computer resumes from sleep mode.

Power-on password

If you set a power-on password, the icon
Enter the correct password to use the computer.

© Copyright Lenovo 2019 39

is displayed on the screen when you turn on the computer.

Supervisor password

The supervisor password protects the system information stored in UEFI BIOS. When entering the UEFI

BIOS menu, enter the correct supervisor password when you are prompted by the icon

. You also can
press Enter to skip the password prompt. However, you cannot change most of the system configuration
options in UEFI BIOS.

If you have set both the supervisor password and power-on password, you can use the supervisor password
to access your computer when you turn it on. The supervisor password overrides the power-on password.

System management password

The system management password can also protect the system information stored in UEFI BIOS like a
supervisor password, but it has lower authority by default. The system management password can be set
through the UEFI BIOS menu or through Windows Management Instrumentation (WMI) with the Lenovo
client-management interface.

You can enable the system management password to have the same authority as the supervisor password
to control security related features. To customize the authority of the system management password through
the UEFI BIOS menu:

1. Enter the UEFI BIOS menu. See “Enter the UEFI BIOS menu” on page 45.

Note: When you are prompted by the icon

, enter the correct supervisor password if a supervisor
password has been set, or enter the correct system management password if no supervisor password
has been set. Otherwise, you cannot change the configurations in the following steps.

2. Select Security ➙ Password ➙ System Management Password Access Control.

3. Follow the on-screen instructions.

If you have set both the supervisor password and the system management password, the supervisor
password overrides the system management password. If you have set both the system management
password and the power-on password, the system management password overrides the power-on
password.

Hard disk passwords

The hard disk password prevents unauthorized access to the data on the storage drive. When a hard disk
password is set, you are prompted to type a correct password each time you try to access the storage drive.

To set the hard disk password, select one of the following types:

• User hard disk password only
When a user hard disk password is set without a master hard disk password, the user must enter the user

hard disk password to access files and applications on the storage drive.

• Master hard disk password + User hard disk password
The master hard disk password is set and used by a system administrator. It enables the administrator to

access any storage drive in a system or any computer connected in the same network. The administrator
can also assign a user hard disk password for each computer in the network. The user of the computer
can change the user hard disk password as desired, but only the administrator can remove the user hard
disk password.

40

L490/L590 User Guide

When prompted to enter a hard disk password, press F1 to switch between the master hard disk password

and user hard disk password .

provider to have the storage drive replaced. A fee will be charged for parts and service. If the storage drive is

Note:

This error indicates that the operating system or programs cannot create, modify,
or delete data in the non-volatile system UEFI variable storage due to insufficient
storage space after POST.

The non-volatile system UEFI variable storage is used by the UEFI BIOS and by
the operating system or programs. This error occurs when the operating system
or programs store large amounts of data in the variable storage. All data needed
for POST, such as UEFI BIOS setup settings, chipset, or platform configuration
data, are stored in a separate UEFI variable storage.
Press F1 after the error message is displayed to enter the UEFI BIOS menu. A
dialog asks for confirmation to clean up the storage. If you select “Yes”, all data
that were created by the operating system or programs will be deleted except
global variables defined by the Unified Extensible Firmware Interface
Specification. If you select “No”, all data will be kept, but the operating system or
programs will not be able to create, modify, or delete data in the storage.
