UEFI BIOS passwords

You can set passwords in UEFI (Unified Extensible Firmware Interface) BIOS (Basic Input/Output System) to

strengthen the security of your computer.

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, a window is displayed on the screen when you turn on the computer. Enter

the correct password to use 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 in the window prompted. 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.

32 L14 Gen 2 and L15 Gen 2 User Guide

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:

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.

• 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.

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

and user hard disk password.

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.

If this error happens at a service center, Lenovo authorized service personnel will

clean up the non-volatile system UEFI variable storage using the preceding

solution.

Fan error. Press ESC to startup

with limited performance.

The thermal fan might not work correctly. After the error message is displayed,

press ESC within five seconds to start up the computer with limited performance.

Otherwise, the computer will shut down immediately. If the problem still exists

when you starts up next time, have your computer serviced.

Ergonomic information

Good ergonomic practice is important to get the most from your personal computer and to avoid discomfort.

Arrange your workplace and the equipment you use to suit your individual needs and the kind of work that

you perform. In addition, use healthy work habits to maximize your performance and comfort when using

your computer.

Working in the virtual office might mean adapting to frequent changes in your environment. Adapting to the

surrounding light sources, active seating, and the placement of your computer hardware, can help you

improve your performance and achieve greater comfort.

This example shows someone in a conventional setting. Even when not in such a setting, you can follow

many of these tips. Develop good habits, and they will serve you well.

General posture: Make minor modifications in your working posture to deter the onset of discomfort caused

by long periods of working in the same position. Frequent short breaks (at least one 10-minute break every

hour) from your work also help to prevent minor discomfort associated with your working posture. During

these breaks, stand up, move about and stretch your arms, legs, back, neck and shoulders, do eye exercises

to reduce muscle and eye fatigue.

Display: Position the display to maintain a comfortable viewing distance of 510 mm to 760 mm (20 inches to

30 inches). Avoid glare or reflections on the display from overhead lighting or outside sources of light. Keep

the display screen clean and set the brightness to levels that enable you to see the screen clearly. Press the

brightness control keys to adjust display brightness.

Head position: Keep your head and neck in a comfortable and neutral (vertical, or upright) position. To

reduce your risk of tiring your eyes by constantly focusing on your screen, look away from your computer at

least every 20 minutes and gaze at a distant object (at least 20 feet away) for at least 20 seconds.

Chair: Use a chair that gives you good back support and seat height adjustment. Use chair adjustments to

best suit your comfort posture.

Arm and hand position: If available, use chair arm rests or an area on your working surface to provide

weight support for your arms. Keep your forearms, wrists, and hands in a relaxed and neutral (horizontal)

position. Type with a soft touch without pounding the keys.

Leg position: Keep your thighs parallel to the floor and your feet flat on the floor or on a footrest.

What if you are traveling?

It might not be possible to observe the best ergonomic practices when you are using your computer while on

the move or in a casual setting. Regardless of the setting, try to observe as many of the tips as possible.

Sitting properly and using adequate lighting, for example, helps you maintain desirable levels of comfort and

performance. If your work area is not in an office setting, ensure to take special note of employing active

sitting and taking work breaks. Many product solutions are available to help you modify and expand your

computer to best suit your needs. You can find some of these options at https://www.lenovo.com/accessories.

Explore your options for docking solutions and external products that provide the adjustability and features

that you want.

Questions about vision?

The visual display screens of notebook computers are designed to meet the highest standards. These visual

display screens provide you with clear, crisp images and large, bright displays that are easy to see, yet easy

on the eyes. Any concentrated and sustained visual activity can be tiring. If you have questions on eye

fatigue or visual discomfort, consult a vision-care specialist for advice.

Low Blue Light (for selected models)

Computer display emits blue light. Blue light, also known as high-energy visible (HEV) light, has the shortest

wavelength of visible light (380nm to 500nm), and therefore produces the highest amount of energy.

Prolonged exposure to a blue light may cause temporary visual fatigue. This computer is shipped from the

factory in low blue light mode, this can help to improve visual fatigue.
