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 53. If you have any questions or
concerns, contact the Customer Support Center.
https://support.lenovo.com. The Lenovo Support
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 2020 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
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.

P520 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 2020 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

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
