Service and upgrades
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: Some computer parts can be upgraded or replaced by the customer. Upgrades typically are referred
to as options. 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 install options or replace CRUs. You must closely follow all instructions when installing or
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. For more information
about CRUs, refer to Chapter 7 “Hardware removal and installation” on page 59. 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.
CAUTION:
Keep fingers and other parts of your body away from hazardous, moving parts. If you suffer an injury,
seek medical care immediately.
CAUTION:
Avoid contact with 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.
CAUTION:
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.
CAUTION:
© Copyright Lenovo 2022 iii
When replacing CRUs, be cautious of sharp edges or corners that might cause injury. If you suffer an
injury, seek medical care immediately.
Static electricity prevention
Static electricity, although harmless to you, can seriously damage computer components and options.
Improper handling of static-sensitive parts can damage the part. When you unpack an option or CRU, do not
open the static-protective package containing the part until the instructions direct you to install it.
When you handle options or CRUs, or perform any work inside the computer, take the following precautions
to avoid static-electricity damage:
• Limit your movement. Movement can cause static electricity to build up around you.
• Always handle components carefully. Handle adapters, memory modules, and other circuit boards by the
edges. Never touch exposed circuitry.
• Prevent others from touching components.
• When you install a static-sensitive option or CRU, touch the static-protective package containing the part
to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two
seconds. This reduces static electricity in the package and your body.
• When possible, remove the static-sensitive part from the static-protective packaging and install the part
without setting it down. When this is not possible, place the static-protective packaging on a smooth, level
surface and place the part on it.
• Do not place the part on the computer cover or other metal surface.
Power cords and power adapters
Use only the power cords and power adapters supplied by the product manufacturer. Do not use the ac
power cord for other devices.
The power cords shall be safety approved. For Germany, it shall be H05VV-F, 3G, 0.75 mm
2
, or better. For
other countries, the suitable types shall be used accordingly.
Never wrap a power cord around a power adapter or other object. Doing so can stress the cord in ways that
can cause the cord to fray, crack, or crimp. This can present a safety hazard.
Always route power cords so that they will not be walked on, tripped over, or pinched by objects.
Protect power cord and power adapters from liquids. For instance, do not leave your power cord or power
adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers. Liquids can cause a short
circuit, particularly if the power cord or power adapter has been stressed by misuse. Liquids also can cause
gradual corrosion of power cord terminals and/or the connector terminals on a power adapter, which can
eventually result in overheating.
Ensure that all power cord connectors are securely and completely plugged into receptacles.
Do not use any power adapter that shows corrosion at the ac input pins or shows signs of overheating (such
as deformed plastic) at the ac input or anywhere on the power adapter.
Do not use any power cords where the electrical contacts on either end show signs of corrosion or
overheating or where the power cord appears to have been damaged in any way.
iv
P920 User Guide
Extension cords and related devices
Ensure that extension cords, surge protectors, uninterruptible power supplies, and power strips that you use
are rated to handle the electrical requirements of the product. Never overload these devices. If power strips
are used, the load should not exceed the power strip input rating. Consult an electrician for more information
if you have questions about power loads, power requirements, and input ratings.
Plugs and outlets
If a receptacle (power outlet) that you intend to use with your computer equipment appears to be damaged
or corroded, do not use the outlet until it is replaced by a qualified electrician.
Do not bend or modify the plug. If the plug is damaged, contact the manufacturer to obtain a replacement.
Do not share an electrical outlet with other home or commercial appliances that draw large amounts of
electricity. Otherwise, unstable voltage might damage your computer, data, or connected devices.
Some products are equipped with a three-pronged plug. This plug fits only into a grounded electrical outlet.
This is a safety feature. Do not defeat this safety feature by trying to insert it into a non-grounded outlet. If
you cannot insert the plug into the outlet, contact an electrician for an approved outlet adapter or to replace
the outlet with one that enables this safety feature. Never overload an electrical outlet. The overall system
load should not exceed 80 percent of the branch circuit rating. Consult an electrician for more information if
you have questions about power loads and branch circuit ratings.
Be sure that the power outlet you are using is properly wired, easily accessible, and located close to the
equipment. Do not fully extend power cords in a way that will stress the cords.
Be sure that the power outlet provides the correct voltage and current for the product you are installing.
Carefully connect and disconnect the equipment from the electrical outlet.
External devices
Do not connect or disconnect any external device cables other than Universal Serial Bus (USB) cables while
the computer power is on; otherwise, you might damage your computer. To avoid possible damage to
connected devices, wait at least five seconds after the computer is shut down to disconnect external
devices.
Heat and product ventilation
Computers, power adapters, and many accessories can generate heat when turned on and when batteries
are charging. Always follow these basic precautions:
• Do not leave your computer, power adapter, or accessories in contact with your lap or any part of your
body for an extended period when the products are functioning or when the battery is charging. Your
computer, power adapter, and many accessories produce some heat during normal operation. Extended
contact with the body could cause discomfort or, potentially, a skin burn.
© Copyright Lenovo 2022 v
• Do not charge the battery or operate your computer, power adapter, or accessories near flammable
materials or in explosive environments.
• Ventilation slots, fans, and heat sinks are provided with the product for safety, comfort, and reliable
operation. These features might inadvertently become blocked by placing the product on a bed, sofa,
carpet, or other flexible surface. Never block, cover, or disable these features.
Inspect your desktop computer for dust accumulation at least once every three months. Before inspecting
your computer, turn off the power and unplug the computer's power cord from the electrical outlet; then
remove any dust from vents and perforations in the bezel. If you notice external dust accumulation, then
examine and remove dust from the inside of the computer including heat sink inlet fins, power supply vents,
and fans. Always turn off and unplug the computer before opening the cover. If possible, avoid operating
your computer within two feet of high-traffic areas. If you must operate your computer in or near a high-traffic
area, inspect and, if necessary, clean your computer more frequently.
For your safety and to maintain optimum computer performance, always follow these basic precautions with
your desktop computer:
• Keep the cover closed whenever the computer is plugged in.
• Regularly inspect the outside of the computer for dust accumulation.
• Remove dust from vents and any perforations in the bezel. More frequent cleanings might be required for
computers in dusty or high-traffic areas.
• Do not restrict or block any ventilation openings.
• Do not store or operate your computer inside furniture, as this might increase the risk of overheating.
• Airflow temperatures into the computer should not exceed 35°C (95°F).
• Do not install air filtration devices. They may interfere with proper cooling.

Chapter 3. You and your computer
This chapter provides information about accessibility, ergonomic, and cleaning and maintenance.
Arranging your workspace
Arrange your workspace to suit your needs and the kind of work you do. This section provides information
about the factors that affect the way you arrange your workspace.
Glare and lighting
Position the monitor to minimize glare and reflections from overhead lights, windows, and other light
sources. Reflected light from shiny surfaces can cause annoying reflections on your screen. When possible,
place the monitor at right angles to windows and other light sources. If necessary, reduce overhead lighting
by turning off lights or using lower wattage bulbs. If you install the monitor near a window, use curtains or
blinds to block the sunlight. You can adjust the brightness and contrast controls on the monitor as the room
lighting changes throughout the day.
Where it is impossible to avoid reflections or to adjust the lighting, an antiglare filter placed over the screen
might be helpful. However, these filters might affect the clarity of the image on the screen; try them only after
you have exhausted other methods of reducing glare.
Air circulation
Your computer produces heat. The computer has a fan that pulls in fresh air and forces out hot air through
the air vents. Blocking the air vents can cause overheating, which might result in a malfunction or damage.
Position the computer so that nothing blocks the air vents; usually, 51 mm (2 inches) of air space is sufficient.
Ensure that the vented air is not blowing on people.
Electrical outlet locations and cable lengths
The following factors might determine the final placement of your computer:
• Locations of electrical outlets
• Length of power cords or power adapters
• Length of the cables that are connected to other devices
For more information about power cords or power adapters, see “Power cords and power adapters” on page
iv.
Comfort
Although no single working position is ideal for everyone, here are a few guidelines to help you find a position
that suits you best. The following figure sets an example for your reference.
© Copyright Lenovo 2022 23
• Screen position: Keep the screen at a comfortable viewing distance, usually 51–61 cm (20–24 inches).
Then, adjust the screen so that the top of the screen is at or slightly below eye level and you can view it
without twisting your body.
• Chair position: Use a chair that gives you good back support and seat height adjustment. Use chair
adjustments to best suit your desired posture.
• Head position: Keep your head and neck in a comfortable and neutral (vertical or upright) position.
• Arm and hand positions: 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.
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 from your work also help to prevent minor discomfort
associated with your working posture.

Using BIOS passwords
By using the Setup Utility program, you can set passwords to prevent unauthorized access to your computer
and data.
You do not have to set any passwords to use your computer. However, using passwords improves computer
security. If you decide to set any passwords, read the following topics.
Password types
The following types of passwords are available in the Setup Utility program:
• Power-on password
When a power-on password is set, you are prompted to enter a valid password each time the computer is
turned on. The computer cannot be used until the valid password is entered.
• Administrator password
Setting an administrator password deters unauthorized users from changing configuration settings. If you
are responsible for maintaining the configuration settings of several computers, you might want to set an
administrator password.
When an administrator password is set, you are prompted to enter a valid password each time you try to
access the Setup Utility program. The Setup Utility program cannot be accessed until a valid password is
entered.
If both the power-on password and administrator password are set, you can enter either password.
However, you must use your administrator password to change any configuration settings.
• Hard disk password
Setting a hard disk password prevents unauthorized access to the data on the internal storage drive (such
as a hard disk drive). When a hard disk password is set, you are prompted to enter a valid password each
time you try to access the storage drive.
Notes:
– Even if the storage drive is removed from one computer and installed in another, the hard-disk
password is still valid.
– If the hard disk password is forgotten, there is no way to reset the password or recover data from the
storage drive.
Password considerations
A password can be any combination of up to 64 alphabetic and numeric characters. For security reasons, it
is recommended to use a strong password that cannot be easily compromised.
Note: The Setup Utility program passwords are case-sensitive.
To set a strong password, consider the following guidelines:
• Have at least eight characters in length
• Contain at least one alphabetic character and one numeric character
• Not be your name or your user name
• Not be a common word or a common name
• Be significantly different from your previous passwords

When a group of independent physical storage drives is set up to use RAID technology, they are in a RAID
array. This array distributes data across multiple storage drives, but the array appears to the host computer
as one single storage unit. Creating and using RAID arrays provides high performance, such as the expedited
I/O performance, because several drives can be accessed simultaneously.
RAID drive groups configured according to certain RAID levels also improve data storage reliability and fault
tolerance compared with single-drive storage systems. Data loss resulting from a drive failure can be
prevented by reconstructing missing data from the remaining drives.
Note: For RAID 0, the missing data resulting from a drive failure cannot be reconstructed.

Chapter 7. Hardware removal and installation
This chapter provides instructions on how to remove and install hardware for your computer.
Handling static-sensitive devices
Do not open the static-protective package containing the new part until the defective part has been removed
and you are ready to install the new part. Static electricity, although harmless to you, can seriously damage
computer components and options.
When you handle options and other computer components, take these precautions to avoid static-electricity
damage:
• Limit your movement. Movement can cause static electricity to build up around you.
• Always handle options and other computer components carefully. Handle PCI/PCIe cards, memory
modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.
• Prevent others from touching the options and other computer components.
• Touch the static-protective package containing the part to a metal expansion-slot cover or other
unpainted metal surface on the computer for at least two seconds. This reduces static electricity from the
package and your body before you install or replace a new part.
• When possible, remove the new part from the static-protective package, and install it directly in the
computer without setting the part down. When this is not possible, place the static-protective package on
a smooth, level surface and place the part on the package.
• Do not place the part on the computer cover or other metal surface.

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.
