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, 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.
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.
When prompted to enter a hard disk password, press F1 to switch between the master hard disk password
and user hard disk password.
Note: The hard disk password is not available in the following situations:
* A Trusted Computing Group (TCG) Opal-compliant storage drive and a TCG Opal management software
program are installed in the computer, and the TCG Opal management software program is activated.
* An eDrive storage drive is installed in the computer preinstalled with the Windows 10 operating system.

Set, change, and remove a password
Before you start, print these instructions.
1. Restart the computer. When the logo screen is displayed, press F1 to enter the UEFI BIOS menu.
2. Select Security  Password by using the arrow keys.
3. Select the password type. Then, follow the on-screen instructions to set, change, or remove a
password.
You should record all your passwords and store them in a safe place. If you forget any of your passwords,
any potential repair actions required are not covered under warranty.
What to do if you forget your power-on password
If you forget your power-on password, do the following to remove the power-on password:
* If you have set a supervisor password and remember it:
1. Restart the computer. When the logo screen is displayed, immediately press F1.
2. Type the supervisor password to enter the UEFI BIOS menu.

reset your passwords or recover data from the storage drive. You can contact a Lenovo authorized service
provider to have the storage drive replaced. A fee will be charged for parts and service. If the storage drive is
a CRU (Customer Replaceable Unit), you can also contact Lenovo to purchase a new storage drive to
replace the old one by yourself. To check whether the storage drive is a CRU and the relevant replacement
procedure, see Chapter 7 "CRU replacement" on page 49.
What to do if you forget your supervisor password
If you forget your supervisor password, there is no service procedure to remove the password. You have to
contact a Lenovo authorized service provider to have the system board replaced. A fee will be charged for
parts and service.

Use Power Loss Protection function (for selected models)
For models shipped with an NVMe (Non-Volatile Memory express) M.2 solid-state drive, the M.2 solid-state

you can tap your finger on the fingerprint reader to log in to Windows.
Enroll your fingerprints
Open the Start menu and then click Settings  Accounts  Sign-in options. Then, follow the on-screen
instructions to finish the enrollment.
During the enrollment, the fingerprints are associated with the Windows password automatically. It is
recommended that you put your finger at the middle of the fingerprint reader during enrollment and enroll
more than one fingerprint in case of any injuries to your fingers.

Chapter 5. Secure your computer and information

Associate your fingerprints with your power-on password and hard disk password
1. Turn off and then turn on the computer.
2. When prompted, scan your finger on the fingerprint reader.
3. Enter your power-on password, hard disk password, or both as required. The connection is created.
When you start the computer again, you can use your fingerprints to log in to the computer without entering
your Windows password, power-on password, or hard disk password. To change the settings, go to the
UEFI BIOS menu.
Attention: If you always use your fingerprint to log in to the computer, you might forget your passwords.
Write down your passwords, and keep them in a safe place.
Maintain the fingerprint reader
To ensure that the fingerprint reader works correctly, do not:
* Scratch the surface of the reader with anything hard.
* Use or touch the reader with a wet, dirty, wrinkled, or injured finger.

Use face authentication (for selected models)
If your computer comes with a Windows Hello-compatible infrared camera, you can unlock your computer by
scanning your face instead of using a password.
Note: If your computer is equipped with a ThinkShutter, slide the ThinkShutter to uncover the camera lens
before using the Windows Hello face recognition.
Create face ID

Appendix A. Important safety information
Safety notices
This information can help you safely use your computer. Follow and retain all information included with your
computer. The information in this document does not alter the terms of your purchase agreement or the
Limited Warranty. For more information, see Safety and Warranty Guide that comes with your computer.
Customer safety is important. Our products are developed to be safe and effective. However, personal
computers are electronic devices. Power cords, power adapters, and other features can create potential
safety risks that can result in physical injury or property damage, especially if misused. To reduce these risks,
follow the instructions included with your product, observe all warnings on the product and in the operating
instructions, and review the information included in this document carefully. By carefully following the
information contained in this document and provided with your product, you can help protect yourself from
hazards and create a safer computer work environment.
Note: This information includes references to power adapters and batteries. In addition, some products
(such as speakers and monitors) ship with external power adapters. If you have such a product, this
information applies to your product. In addition, computer products contain a coin-sized internal battery that
provides power to the system clock even when the computer is unplugged, so the battery safety information
applies to all computer products.

Important information about using your computer
Ensure that you follow the important tips given here to get the most use and enjoyment out of your computer.
Failure to do so might lead to discomfort or injury, or cause the computer to fail.
Protect yourself from the heat that your computer generates.
When your computer is turned on or the battery is charging, the base,
the palm rest, and some other parts may become hot. The
temperature they reach depends on the amount of system activity and
the level of charge in the battery.
Extended contact with your body, even through clothing, could cause
discomfort or even a skin burn.
* Avoid keeping your hands, your lap, or any other part of your body
in contact with a hot section of the computer for any extended
time.
* Periodically take your hands away from the keyboard by lifting your
hands from the palm rest.

Protect yourself from the heat generated by the ac power adapter.
When the ac power adapter is connected to an electrical outlet and
your computer, it generates heat.
Extended contact with your body, even through clothing, may cause a
skin burn.
* Do not place the ac power adapter in contact with any part of your
body while it is in use.
* Never use it to warm your body.
* Do not wrap the cords around the ac power adapter while in use.

Prevent your computer from getting wet.

To avoid spills and the danger of electrical shock, keep liquids away
from your computer.

Protect the cables from being damaged.

Applying strong force to cables may damage or break them.
Route communication lines, or the cables of an ac power adapter, a
mouse, a keyboard, a printer, or any other electronic device, so that
they cannot be walked on, tripped over, pinched by your computer or
other objects, or in any way subject to treatment that could interfere
with the operation of your computer.

Protect your computer and data when moving it.
Before moving a computer equipped with a storage drive, do one of
the following:
* Turn it off.
* Put it in sleep mode.
* Put it in hibernation mode.
This helps to prevent damage to the computer, and possible loss of
data.

T495s and X395 User Guide

Handle your computer gently.

Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy
objects on your computer, display, or external devices.

Carry your computer carefully.

* Use a quality carrying case that provides adequate cushioning and
protection.
* Do not pack your computer in a tightly packed suitcase or bag.
* Before putting your computer in a carrying case, make sure that it
is off, in sleep mode, or in hibernation mode. Do not put a
computer in a carrying case while it is turned on.

Conditions that require immediate action
Products can become damaged due to misuse or neglect. Some product damage is serious enough
that the product should not be used again until it has been inspected and, if necessary, repaired by an
authorized servicer.
As with any electronic device, pay close attention to the product when it is turned on.
On very rare occasions, you might notice an odor or see a puff of smoke or sparks vent from your
product. You might also hear sounds like popping, cracking, or hissing. These might merely mean that
an internal electronic component has failed in a safe and controlled manner. Or, they might indicate a
potential safety issue. Do not take risks or attempt to diagnose the situation yourself. Contact the
Customer Support Center for further guidance. For a list of Service and Support phone numbers, see
the following Web site:
https://support.lenovo.com/supportphonelist

Frequently inspect your computer and its components for damage, wear, or signs of danger. If you
have any question about the condition of a component, do not use the product. Contact the Customer
Support Center or the product manufacturer for instructions on how to inspect the product and have it
repaired, if necessary.
In the unlikely event that you notice any of the following conditions, or if you have any safety concerns
with your product, stop using the product and unplug it from the power source and
telecommunication lines until you can speak to the Customer Support Center for further guidance.

Service
Do not attempt to service a product yourself unless instructed to do so by the Customer Support Center or
your documentation. Only use a Service Provider who is approved to repair your particular product.
Note: Replacement parts approved for customer installation are referred to as Customer Replaceable Units,
or CRUs. Lenovo provides documentation with instructions when it is appropriate for customers to replace
CRUs. You must closely follow all instructions when replacing parts. The Off state of a power indicator does
not necessarily mean that voltage levels inside a product are zero. Before you remove the covers from a
product equipped with a power cord, always ensure that the power is turned off and that the product is
unplugged from any power source. If you have any questions or concerns, contact the Customer Support
Center.
Although there are no moving parts in your computer after the power cord has been disconnected, the
following warnings are required for your safety.

Keep fingers and other parts of your body away from hazardous, moving parts. If you suffer an injury, seek
medical care immediately.

Do not touch hot surface of hot components inside the computer. During operation, some components
become hot enough to burn the skin. Before you open the computer cover, turn off the computer, disconnect
power, and wait approximately 10 minutes for the components to cool.

After replacing a CRU, reinstall all protective covers, including the computer cover, before connecting power
and operating the computer. This action is important to help prevent unexpected electrical shock and help
ensure the containment of an unexpected fire that could happen under extremely rare conditions.

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.
Night light (Software solution)
Blue light is the high-energy visible light in the light spectrum. Excessive exposure to blue light might damage
your vision. Night light is a feature that reduces the blue light emitted by computer displays. When the night
light is on, your computer display shows warmer colors that help you reduce eye strain.
To turn on or turn off the night light, type Night light in the Windows search box and then press Enter. Then,
follow the on-screen instructions.
Note: Selected Lenovo computers are low blue-light certified. These computers are tested with night light
turned on and color temperature set to the default value of 48 or greater.

Important battery recycling and WEEE information
Take back and recycling information for WEEE and batteries/accumulators in the European Union and the
United Kingdom

The crossed-out wheeled bin marking applies only to countries with WEEE and batteries waste regulations
including the European Union (EU), and United Kingdom (UK).
Appliances and batteries/accumulators are labeled in accordance with local regulations concerning waste
electrical and electronic equipment (WEEE) and waste batteries and waste accumulators. These regulations
determine the framework for the return and recycling of used appliances and used batteries/accumulators as
applicable within each geography. This label is applied to various products to indicate that the product is not
to be thrown away, but rather put in the established collection systems for reclaiming these end of life
products.
The label on the battery may also include a chemical symbol for the metal concerned in the battery (Pb for
lead, Hg for mercury, and Cd for cadmium).
Users of electrical and electronic equipment (EEE) and users of batteries/accumulators with the crossed-out
wheeled bin marking must not dispose of end of life products as unsorted municipal waste, but use the
collection framework available to them for the return, recycle, and recovery of WEEE and waste batteries/
accumulators and to minimize any potential effects of EEE and batteries on the environment and human
health due to the presence of hazardous substances.
Lenovo electrical and electronic equipment (EEE) may contain parts and components, which at end-of-life
might qualify as hazardous waste.
EEE and waste electrical and electronic equipment (WEEE) can be delivered free of charge to the place of
sale or any distributor that sells electrical and electronic equipment of the same nature and function as the
used EEE or WEEE.
Before placing electrical and electronic equipment (EEE) in the waste collection stream or in waste collection
facilities, the end user of equipment containing batteries and/or accumulators must remove those batteries
and accumulators for separate collection.
