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. If you have any
questions or concerns, contact the Customer Support Center.
Although there are no moving parts in the computer after the power cord has been disconnected, the
following warnings are required for your safety.
Moving Parts
Keep fingers and other parts of your body away from hazardous, moving parts. If you suffer an injury, seek
medical care immediately.
Hot Surface
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.

• 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.

Cleaning and maintenance
With appropriate care and maintenance, your computer will serve you reliably. The following topics offer
information to help you keep your computer working with best performance.
Basic maintenance tips
Here are some basic points about keeping your computer functioning properly
• Keep the computer in a clean, dry environment. Ensure that the computer rests on a flat, steady surface.
• Do not cover any of air vents. These air vents provide airflow to keep the computer from overheating.
• Keep electrical appliances such as an electric fan, radio, high-powered speakers, air conditioner, and
microwave oven away from your computer because the strong magnetic fields generated by these
appliances can damage the monitor and data on the storage drive.
• Keep food and drinks away from all parts of the computer. Food particles and spills might make the
keyboard and mouse stick and unusable.
• Do not get the power switches or other controls wet. Moisture can damage these parts and cause an
electrical hazard.
• Always disconnect a power cord by grasping the plug instead of the cord.
• Keep the computer software, device drivers, and operating system up-to-date.
• Empty your recycle bin on a regular basis.
• Clean out your Inbox, Sent Items, and Deleted Items folders in your e-mail application on a regular basis.
• Clean up files and free up storage drive space and memory space occasionally to prevent performance
problems.
• Keep a log book. Entries might include major software or hardware changes, device-driver updates,
intermittent problems and what you did to resolve them, and other issues you might have experienced.
The cause of a problem might be change in hardware, change in software, or any other actions that might
have taken place. A log book can help you or a Lenovo technician determine the cause of a problem.
• Back up your data on the storage drive regularly. You can restore the storage drive from a backup.
• Create a recovery medium as early as possible. You can use the recovery medium to recover your
operating system even if Windows fails to start up.
• Get the most up-to-date operating system update patches, software programs, and device drivers.
Maintenance tips about moving the computer
Before moving the computer, take the following precautions
1. Back up your data on the storage drive.
2. Remove any media from the drives and turn off all connected devices and the computer. Then,
disconnect all power cords from electrical outlets and disconnect all cables that are connected to the
computer.
3. If you saved the original shipping cartons and packing materials, use them to pack the units. If you are
using different cartons, cushion the units to avoid damage.
When you move the computer to another country or region, you must take local electrical standards into
consideration. If the local electrical outlet style is different from the type you are currently using, contact the
Lenovo Customer Support Center to purchase either an electrical plug adapter or a new power cord.

computer
It is a good practice to clean your computer periodically to protect the surfaces and ensure trouble-free
operation.
Clean the computer surface Wipe it with a lint-free cloth dampened in mild soap and water. Avoid applying
liquids directly to the surface.
Clean the keyboard Wipe the keys one by one with a lint-free cloth dampened in mild soap and water. If
you wipe several keys at a time, the cloth might hook onto an adjacent key and possibly damage it. Avoid
spraying cleaner directly onto the keyboard. To remove any crumbs or dust from beneath the keys, you can
use a camera blower with a brush or use cool air from a hair dryer.
Clean the computer screen Scratches, oil, dust, chemicals, and ultraviolet light can affect the performance
of your computer screen. Use a dry, soft lint-free cloth to wipe the screen gently. If you see a scratchlike
mark on your screen, it might be a stain. Wipe or dust the stain gently with a soft, dry cloth. If the stain
remains, moisten a soft, lint-free cloth with water or eyeglass cleaner, but do not apply liquids directly to your
computer screen. Ensure that the computer screen is dry before closing it.
