Explanation of hard disk capacity
Dear user,
While using your computer, you may discover that the nominal hard
disk capacity indicated is somewhat different from the disk capacity
displayed by the operating system. For example, a nominal 40GB hard
disk will appear as less than 40GB in the operating system. This
discrepancy is not an error in hard disk installation nor any other
problem, but a normal phenomenon of computers. This phenomenon is
primarily due to the following reasons:
I. Different standards used by the manufacturer and operating
system when calculating hard disk capacity
Hard disk manufacturers use a radix of 1000, i.e. 1GB = 1,000MB,
1MB = 1,000KB, 1KB = 1,000 bytes. However, when identifying hard disk
capacity, operating systems use a radix of 1024, i.e. 1GB = 1,024MB,
1MB = 1,024KB, 1KB = 1,024 bytes. The standard adopted by your
computer is that of the hard disk manufacturers. Since the standards
adopted by the hard disk manufacturer and operating system are different,
the hard disk capacity displayed by the operating system will be different
from the nominal hard disk capacity.
For example, if the hard disk is nominally X GB, even when it is completely
empty, the capacity displayed by the operating system will be:
X × 1000 × 1000 × 1000/ (1024 × 1024 × 1024) ≈ X × 0.931
Page 6
If a portion of the hard disk space has been used for some specific purpose,
then the capacity indicated by the operating system will be even less than
X × 0.931 GB.
II. A portion of the hard disk space is used for specific purposes
Lenovo computers come with preinstalled OneKey™ Rescue System, so
the hard disk has a special portion partitioned before delivery, which is
used to store hard disk mirror and OneKey Rescue System program files.
The size of the reserved space for this partition varies according to the
model, operating system and software of the computer. For the sake of
safety, this partition is not evident, which is commonly referred to as a
“hidden partition”.
In addition, after the hard disk is partitioned or formatted, the system will
assign a certain amount of hard disk space for the system files.
For the above reasons, the available hard disk space indicated by the
operating system is always less than the computer’s nominal hard disk
capacity.

Using Mobile Broadband (specific models only)
Note:
Before using the Mobile Broadband, be sure to see “Safety information
related to Mobile Broadband” in Chapter 6 first.
What is Mobile Broadband
A Mobile Broadband network, also known as a Wireless Wide Area
Network (WWAN), provides Internet access to laptop computers, cell
phones and other devices over a large geographic area. Cellular networks
are used for data transmission, and access is usually provided by a mobile
network operator.
The biggest advantage of Mobile Broadband is that it is accessible from
anywhere you can get a signal from your carrier. Laptop computers with
Mobile Broadband access can stay online on the move, and will not be tied
down by a wired Internet connection.
Various standards are in use by mobile operators to provide Mobile
Broadband service. Depending on the model, your Mobile Broadband
module may support one or more of the following standards:
GSM (Global System for Mobile Communications)
TD-SCDMA (Time Division-Synchronous Code Division Multiple
Access)
SCDMA (Synchronous Code Division Multiple Access)
EV-DO (Evolution Data Optimized)
HSPA (High Speed Packet Access)

Chapter 2. Using your computer
Note:
A mobile network operator, also known as mobile carrier, is a telephony
company that provides mobile telecommunication service to its
subscribers.
Mobile Broadband is a subscription service. Refer to your local mobile
network operator for availability, cost and other information.
Getting started with Mobile Broadband
Before getting started with Mobile Broadband, you first need to choose a
mobile network operator and make sure you are in the coverage area of the
network. After that, you also need:
To activate Mobile Broadband service through your local mobile
network operator. You will get a Subscriber Identity Module (SIM) card
after activation. For instructions on inserting the SIM card, refer to the
“Inserting the SIM card” on page 27.

A compatible device driver is a requirement to ensure correct operation
and performance of each component in your computer. If your computer is
pre-installed with an operating system, Lenovo provides all drivers that
you need in your hard disk.
Using battery and AC adapter - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
When you cannot use the AC adapter to power your computer, you may
depend on battery power to keep your computer running.
Note:
The operating system may run slower when using the battery mode.
Checking battery status
You can determine the percentage of battery power remaining by using
Windows Power options.
As each computer user has different habits and needs, it is difficult to
predict how long a battery charge will last. There are two main factors:
The amount of energy stored in the battery when you begin to work.
The way you use your computer: for example, how often you access the
hard disk drive and how bright you make the computer display.

need to charge the battery or replace it with a charged battery.
If an AC outlet is convenient, first, connect the power cord to the
transformer pack; second, plug the power cord into an electrical outlet; and
then connect the AC adapter to the power jack of the computer.
The charging time is affected by the physical environment.
Note:
To increase the life of the battery, the computer does not start recharging
the battery immediately when it drops from fully-charged.

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 to notebook computers, 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

Chapter 6. Safety, use, and care information
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. Or you might hear sounds like
popping, cracking, or hissing. These conditions might merely mean that an
internal electronic component has failed in a safe and controlled manner.
Or, they might indicate a potential safety issue. However, 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 http://consumersupport.lenovo.com
Frequently inspect your computer and its components for damage or 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.
Power cords, plugs, power adapters, extension cords, surge protectors,
or power supplies that are cracked, broken, or damaged.
Signs of overheating, smoke, sparks, or fire.

Chapter 6. Safety, use, and care information
Service and upgrades
Attention:
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 an ac power cord, always make sure that the power is
turned off and that the product is unplugged from any power source. For
more information on CRUs, see “Appendix B. Customer Replaceable Units
(CRUs)” on page 113. 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.
Danger:
Hazardous moving parts. Keep fingers and other body parts away.
66
Page 76
Chapter 6. Safety, use, and care information
Attention:
Before replacing any CRUs, turn off the computer and wait three to five
minutes to let the computer cool before opening the cover.
Power cords and power adapters
Danger:
Use only the power cords and power adapters supplied by the product
manufacturer. The power cord and power adapter are intended for use
with this product only. They should never be used with any other product.
The power cords shall be safety approved. For Germany, it shall be
H03VV-F, 3G, 0.75 mm
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 or any other cables so that they will not be
walked on, tripped over, or pinched by objects.
Protect power cords 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
2
, or better. For other countries, the suitable types

terminals and/or the connector terminals on a power adapter, which can
eventually result in overheating.
Always connect power cords and signal cables in the correct order and
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.

Chapter 6. Safety, use, and care information
Extension cords and related devices
Danger:
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
Danger:
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 attached 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
69
Page 79
Chapter 6. Safety, use, and care information
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.

Though your computer is designed to function reliably in normal work
environments, you need to use common sense in handling it. By following
these important tips, you will get the most use and enjoyment out of your
computer.
Be careful about where and how you work
Do not leave the base of your computer, or any other part that becomes
hot during operation, in contact with your lap or any part of your body
for an extended period when the computer is functioning or when the
battery is charging. Your computer dissipates some heat during normal
operation. This heat is a function of the level of system activity and
battery charge level. Extended contact with your body, even through
clothing, could cause discomfort or, eventually, a skin burn.
When the AC adapter is connected to an electrical outlet and your
computer, it generates heat. Do not place the adapter in contact with any
part of your body while using it. Never use the AC adapter to warm
your body. Extended contact with your body, even through clothing,
may cause a skin burn.
Route the cables of an AC adapter, a mouse, a keyboard, a printer, or any
other electronic device, or communication lines, so that they cannot be
walked on, tripped over, pinched by your computer or other objects, or in
any way subjected to treatment that could disturb the operation of your
computer. Applying strong force to the cables may damage or break them.
82
Page 92
Chapter 6. Safety, use, and care information
Place liquids away from your computer to avoid spills, and keep your
computer away from water (to avoid the danger of electrical shock).
Do not eat or smoke over your keyboard. Particles that fall into your
keyboard can cause damage.
Store packing materials safely out of the reach of children to prevent the
risk of suffocation from plastic bags.
Keep your computer away from magnets, activated cellular phones,
electrical appliances, or speakers (within 13 cm or 5 in).
Avoid subjecting your computer to extreme temperatures (below 5°C/
41°F or above 35°C/95°F).
Some appliances, such as certain portable desktop fans or air purifiers,
can produce negative ions. If a computer is close to such an appliance,
and is exposed for an extended time to air containing negative ions, it
may become electrostatically charged. Such a charge may be discharged
through your hands when you touch the keyboard or other parts of the
computer, or through connectors on I/O devices connected to it. Even
though this kind of electrostatic discharge (ESD) is the opposite of a
discharge from your body or clothing to the computer, it poses the same
risk of a computer malfunction.
Your computer is designed and manufactured to minimize any effects of
electrostatic charge. An electrostatic charge above a certain limit,
however, can increase the risk of ESD. Therefore, when using the
computer close to an appliance that can produce negative ions, give
special attention to the following:
- Avoid directly exposing your computer to the air from an appliance
that can produce negative ions.
- Keep your computer and peripherals as far as possible from such an
appliance.
83
Page 93
Chapter 6. Safety, use, and care information
- Wherever possible, ground your computer to facilitate safe
electrostatic discharge.
Note:
Not all such appliances cause a significant electrostatic charge.
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 staticprotective 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.
- Whenever possible, remove the static-sensitive part from the staticprotective 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.
