.
Lenovo encourages you to make efficient use of energy an integral part of
your day-to-day operations. To help in this endeavor, Lenovo has preset the
following power-management features to take effect when your computer
has been inactive for a specified duration:

Table 1. ENERGY STAR power-management features, by operating system

power button on your keyboard. For more information about these
settings, refer to your Windows Help and Support information system.

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

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 OneKeyTM 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.

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.

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.

property damage.

55

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 101. 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.

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

Caring Your Computer - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

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.

70

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.

71

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.

72

73

Chapter 6. Safety, Use, and Care Information

 When you leave the computer in your car, place it on the back seat to

avoid being insolated.

 Carry the AC adapter and power cord with the computer.

 Handle Storage Media and Drives Properly

 If your computer comes with an optical drive, do not touch the surface of

a disc or the lens on the tray.

 Wait until you hear the CD or DVD click into the center pivot of an

optical drive before closing the tray.

 When installing your hard disk, follow the instructions shipped with

your hardware, and apply pressure only where needed on the device.

 Data Safety

 Do not delete unknown files or change the name of files or directories

that were not created by you; otherwise, your computer software might
fail to work.

 Be aware that accessing network resources can leave your computer

vulnerable to computer viruses, hackers, spyware, and other malicious
activities that might damage your computer, software, or data.

 It is your responsibility to ensure that you have adequate protection in

the form of firewalls, antivirus software, and anti-spyware software and

Chapter 6. Safety, Use, and Care Information

Device drivers are programs that contain instructions for the operating
system about how to operate or “drive” a certain piece of hardware. Each
hardware component on your computer has its own specific driver. If you
add a new component, the operating system needs to be instructed on
how to operate that piece of hardware. After you install the driver, the
operating system can recognize the hardware component and understand
how to use it.

Note:



Due to the fact that drivers are programs, like any other file on your
computer, they are susceptible to corruption and might not perform
properly if corruption occurs.
