Problem: The capacity of the hard disk, as indicated by the system, is less than
the nominal capacity.
Troubleshooting and problem resolution: For computers equipped with the
OneKey Recovery feature, the system recovery feature needs to occupy some
hard disk space. This may account for the apparent hard disk capacity deficit.
Further Technical Explanation: The nominal capacity of the hard disk is
expressed in the decimal system as 1000 bytes. But the actual hard disk capacity
is expressed in the binary system as 1024 bytes (For example, the nominal
capacity 1G is 1000M, while the actual capacity 1G is 1024M).
The capacity of the hard disk shown in Windows can be calculated according to
the calculations in the following example:
The nominal capacity of the hard disk is 40G, while its actual capacity
should be: 40 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 37G.
If the Service partition of 3G - 3 x 1000 x 1000 x 1000/(1024 x 1024 x
1024) = 2.79G is subtracted, the capacity of the hard disk shown in the
system can be obtained.
The capacity of the hard disk as calculated using this method may be slightly
different from the actual capacity due to the rounding of totals.

BIOS setup utility
What is the BIOS setup utility?
The BIOS setup utility is ROM-based software. It communicates basic computer
information and provides options for setting boot devices, security, hardware
mode, and other preferences.
How can I start the BIOS setup utility?
To start the BIOS setup utility:
1. Shut down the computer.
2. Repeatedly press and release the F1 key once turning on the computer to start
the Setup Utility program.
How can I change the boot mode?
There are two boot modes: UEFI and Legacy. To change the boot mode, start the
BIOS setup utility and select Startup → Boot Priority, then set boot mode to UEFI
or Legacy support on the boot menu.
When do I need to change the boot mode?
The default boot mode for your computer is the UEFI mode. If you need to install
a legacy Windows operating system (any operating system before Windows 8) on
your computer, you must change the boot mode to Legacy support. The legacy
Windows operating system cannot be installed if you don’t change the boot mode.

Performing Daily Maintenance Tasks
Cleaning the computer components
Because many of the computer components consist of sophisticated integrated
circuit boards, it is very important to periodically clean the computer to prevent
dust buildup. The cleaning supplies you need to clean the components include:
a vacuum cleaner, a soft cotton cloth, pure water (preferably purified or distilled
water) and cotton swabs.
Attention: Before you clean your computer, disconnect the computer
from the electrical outlet. Clean your computer with a soft cloth
dampened with water. Do not use liquid or aerosol cleaners, which may
contain flammable substances.
Note: To avoid damaging the computer or display, do not spray cleaning
solution directly onto the display. Only use products specifically designed
for cleaning displays, and follow the instructions included with the product.
The following are general methods for cleaning the components:
•
You can use a soft cloth to remove dust on the surface of the computer, the
monitor, the printer, the speakers and the mouse.
•
•
You can use a vacuum cleaner to clean in otherwise inaccessible corners.
To clean the keyboard thoroughly, shut down the computer and scrub it gently
with a wet cloth. Do not use the keyboard until it is dry.
Do not do any of the following:
•
•
•
Allow water to enter the computer.
Use a heavily dampened cloth.
Spray water directly onto the surface of the monitor or inside the computer.
LCD monitor should be cleaned daily. Use a dry cloth to brush dust from the
monitor and keyboard every day. Keep all surfaces clean and free of grease stains.

Overview
This guide is intended to be used by customers who are replacing Customer
Replaceable Units (CRUs) as well as trained service personnel who are replacing
Field Replaceable Units (FRUs). In this guide, CRUs and FRUs will often be referred
to as parts.
Note: Trained service personnel should refer to the Hardware Maintenance
Manual (HMM) for parts ordering information.
This guide does not include procedures for the replacement of all parts. It is
expected that trained service personnel are already able to replace cables, switches,
and certain mechanical parts without the need for step-by-step procedures.
Note: Use only parts provided by Lenovo®.
The description of the TV-Tuner card in this manual applies only to computer
models with a TV-Tuner card, and therefore does not apply to models without a
TV-Tuner card.
This guide contains instructions for replacing the following parts:
•
•

•
Memory modules
Hard disk drive
Optical disk drive
Graphics card
TV-Tuner card
Safety information for replacing CRUs

Handling static-sensitive devices
Static electricity, although harmless to you, can seriously damage computer
components.
When replacing a part, do not open the anti-static packaging containing the new
part until the defective part has been removed from the computer and you are
ready to install the new part.
When handling parts and other computer components, the following precautions
should be taken in order to avoid static electricity damage:
•
•
Limit your movements, as movement can cause the build-up of static electricity.
Always handle parts and other computer components with care, and handle
adapters, memory modules, system boards, and microprocessors by their
edges. Never touch any exposed circuitry.
•
•
Prevent others from touching parts and other computer components.
Before replacing a new part, first place the anti-static packaging containing the
part against a metal expansion slot cover or other unpainted metal surface on
the computer for at least two seconds. This will reduce static electricity in the
package and your body.
•
•
When possible, remove the new part from its anti-static packaging and install it
directly into the computer without setting the part down. If this is not possible,
place the part on top of its anti-static packaging on a smooth, flat surface
before installing it.
Do not place parts on the computer cover or other metal surface.

Identifying parts on the system board
The system board (also known as the “mainboard” or “motherboard”) is the main
circuit board in your computer. It provides basic computer functions and supports
a variety of devices that are factory-installed or that you can install later.
The following illustrations show the locations of the different parts on the system
board.
