Explanation of hard disk capacity  
Dear user,  
While using your computer, you may find 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., 1G = 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 G, 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 G  
Download from Www.Somanuals.com. All Manuals Search And Download.  
In addition, 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 G.  
II. A portion of the hard disk space is used for specific purposes  
Lenovo computers may 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 apparent, 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 AC adapter and battery -----------------------------------------------  
Checking battery status  
You can determine the percentage of battery power remaining by using  
Windows Power Options.  
Note: 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 commence 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.  
Charging the battery  
When you find that the battery power is low, you need to charge the  
battery or replace it with a fully charged one.  
The battery is charged when the AC adapter is connected to the computer  
and the battery is installed.  
Charging time will depend on the usage environment.  
You need to charge the battery in any of the following situations:  
• When you purchase a new battery  
• If the battery status indicator starts blinking  
• If the battery has not been used for a long time

Chapter 4. OneKey Rescue System  
OneKey Rescue System -----------------------------------------------------------  
Introduction  
The Lenovo OneKey Rescue System is an easy-to-use application that can  
be used to back up the data on your system partition (C drive) for easy  
restore when required. You can run Lenovo OneKey Recovery under the  
Windows operating system, and the OneKey Rescue System without  
starting the Windows operating system.  
Attention:  
In order to utilize the features of the OneKey Rescue System, your hard  
disk already includes a hidden partition by default to store the system  
image file and OneKey Rescue System program files. This default partition  
is hidden for security reasons and is the reason the available disk space is  
less than it claims. The exact available hard disk space depends on the file  
size of the mirror image file (based on the size of operating system and  
pre-installed software).

Appendix B. Use, and care Information  
Caring for 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 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  
64  
Download from Www.Somanuals.com. All Manuals Search And Download.  
       
Appendix B. Use, and care Information  
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.  
- Wherever possible, ground your computer to facilitate safe  
electrostatic discharge.  
Notice of static-electricity  
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.  
65  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Appendix B. Use, and care Information  
- 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.  
- Whenever 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.  
Be gentle with your computer  
• Avoid placing any objects (including paper) between the display and the  
keyboard or under the keyboard.  
• Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy  
objects on your computer, display, or external devices.  
• Avoid turning the display beyond 180°.  
Carry your computer properly  
• Before moving your computer, be sure to remove any media, turn off  
attached devices, and disconnect cords and cables.  
• Be sure your computer is in standby or hibernation mode, or turned off,  
before moving it. This will prevent damage to the hard disk drive and  
data loss.  
66  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Appendix B. Use, and care Information  
• When picking up your open computer, hold it by the bottom. Do not  
pick up or hold your computer by the display.  
• Use a quality carrying case that provides adequate cushion and  
protection. Do not pack your computer in a tightly packed suitcase or  
bag.  
For outdoor use  
• Backup your critical data before you take your computer outdoors.  
• Ensure that the battery is full.  
• Be sure to turn off the power and close the LCD well.  
• 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.

Appendix B. Use, and care Information  
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  
keep this software up to date.  
Take care in setting passwords  
• Remember your passwords. If you forget a supervisor or hard disk  
password, Lenovo authorized service providers will not reset it, and you  
might have to replace your system board or hard disk drive.  
Other important tips  
• Do not put the battery pack in trash that is disposed of in landfills. When  
disposing of the battery, comply with local ordinances or regulations and  
your company’s safety standards.  
• Your computer might have both an Ethernet connector and a modem  
connector. If so, be sure to connect your communication cable to the  
correct one, so your connector is not damaged.

Appendix B. Use, and care Information  
• Register your Lenovo products with Lenovo (refer to the Web page:  
http://consumersupport.lenovo.com). This can help authorities return  
your computer to you if it is lost or stolen. Registering your computer  
also enables Lenovo to notify you about possible technical information  
and upgrades.  
• Only an authorized Lenovo repair technician should disassemble and  
repair your computer.  
• Do not modify or tape the latches to keep the display open or closed.  
Take care not to turn your computer over while the AC adapter is  
plugged in. This could break the adapter plug.  
Turn off your computer if you are replacing a device, or else verify that  
the device is warm- or hot-swappable.  
• Before you install any of the following devices, touch a metal table or a  
grounded metal object. This action reduces any static electricity from  
your body. The static electricity could damage the device.  
- ExpressCard  
- Memory Card, such as SD Card, Memory Stick, MultiMediaCard, and  
Memory Stick Pro card.  
- Memory module  
• When transferring data to or from a Flash Media Card, such as an SD  
card, do not put your computer in standby or hibernation mode before  
the data transfer is complete. To do so might cause damage to your data.

Questions about vision?  
Your computer’s visual display screen is designed to meet the highest  
standards and to provide you with clear, crisp images and large, bright  
displays that are easy to see, yet easy on the eyes. Of course, any  
concentrated and sustained visual activity can be tiring. If you have  
questions on eye fatigue or visual discomfort, consult a vision care  
specialist for advice.

1 Customer Replaceable Unit (“CRU”) Service  
Under CRU Service, your Service Provider will ship CRUs to you for  
installation by you. CRU information and replacement instructions are  
shipped with your product and are available from Lenovo at any time  
upon request. CRUs that are easily installed by you are called Self-service  
CRUs, while Optional-service CRUs may require some technical skill and  
tools. Installation of Self-service CRUs is your responsibility. You may  
request that a Service Provider install Optional-service CRUs under one of  
the other types of warranty service designated for your product. An  
optional service offering may be available for purchase from Lenovo to  
have Lenovo install Self-service CRUs for you. You may find a list of CRUs  
and their designation in the publication that ships with your product or at  
www.lenovo.com/CRUs. The requirement to return a defective CRU, if  
any, will be specified in the materials shipped with a replacement CRU.  
When return is required: 1) return instructions, a prepaid return shipping  
label, and a container will be included with the replacement CRU; and 2)  
you may be charged for the replacement CRU if your Service Provider does  
not receive the defective CRU within thirty (30) days of your receipt of the  
replacement.

Under On-Site Service, your Service Provider will either repair or exchange  
the product at your location. You must provide a suitable working area to  
allow disassembly and reassembly of the Lenovo product. For some  
products, certain repairs may require your Service Provider to send the  
product to a designated service center.  
3 Courier or Depot Service  
Under Courier or Depot Service, your product will be repaired or  
exchanged at a designated service center, with shipping arranged by your  
Service Provider. You are responsible for disconnecting the product. A  
shipping container will be provided to you for you to return your product  
to a designated service center. A courier will pick up your product and  
deliver it to the designated service center. Following its repair or exchange,  
the service center will arrange the return delivery of the product to you.

Under Customer Carry-In or Mail-In Service, your product will be repaired  
or exchanged at a designated service center, with delivery or shipping  
arranged by you. You are responsible to deliver or mail, as your Service  
Provider specifies, (prepaid by you unless specified otherwise) the product,  
suitably packaged to a designated location. After the product has been  
repaired or exchanged, it will be made available for your collection. Failure  
to collect the product may result in your Service Provider disposing of the  
product as it sees fit. For Mail-in Service, the product will be returned to  
you at Lenovo’s expense, unless your Service Provider specifies otherwise.

5 Product Exchange Service  
Under Product Exchange Service, Lenovo will ship a replacement product  
to your location. You are responsible for its installation and verification of  
its operation. The replacement product becomes your property in exchange  
for the failed product, which becomes the property of Lenovo. You must  
pack the failed product in the shipping carton used to ship the replacement  
product and return it to Lenovo. Transportation charges, both ways, are

Appendix D. Customer replaceable units (CRUs)  
Customer Replaceable Units (CRUs) are computer parts that can be  
upgraded or replaced by the customer. There are two types of CRUs:  
internal and external. External CRUs are easy to install, whereas internal  
CRUs require some technical skills and in some cases might require tools  
such as a screwdriver. However, both internal and external CRUs are safe  
for removal by the customer.  
Customers are responsible for replacing all external CRUs. Internal CRUs  
can be removed and installed by customers or by a Lenovo service  
technician during the warranty period.  
Your computer contains the following types of external CRUs:  
External CRUs (pluggable): These CRUs unplug from the computer.  
Examples of these types of CRUs include the AC adapter and power  
cord.  
External CRUs with latches: These CRUs include a latch to help you  
remove and replace the part. Examples of these types of CRUs include  
the notebook main battery, an optical drive, a hard-disk drive, and an  
extended battery.

Appendix D. Customer replaceable units (CRUs)  
Your computer contains the following types of internal CRUs:  
Internal CRUs (located behind an access panel): These CRUs are  
isolated parts within the computer that are concealed by an access panel  
that is typically secured by either one or two screws. Once the access  
panel is removed, only the specific CRU is visible. Examples of these  
types of CRUs include memory modules and hard disk drives.  
Internal CRUs (located within the product): These CRUs are accessible  
only by opening the computer’s outer case. Examples of these CRUs  
include PCI Express Mini Cards and the integrated keyboard.

Usage environment and your health  
Wireless LAN PCI Express Mini Card and Bluetooth Daughter Card emit  
radio frequency electromagnetic energy like other radio devices. However,  
the level of energy emitted is far much less than the electromagnetic  
energy emitted by wireless devices like for example mobile phones.  
Due to the fact that wireless LAN PCI Express Mini Card and Bluetooth  
Daughter Card operate within the guidelines found in radio frequency  
safety standards and recommendations, Lenovo believes the integrated  
wireless cards are safe for use by consumers. These standards and  
recommendations reflect the consensus of the scientific community and

continually review and interpret the extensive research literature.  
In some situation or environment, the use of wireless LAN PCI Express  
Mini Card or Bluetooth Daughter Card may be restricted by the proprietor  
of the building or responsible representatives of the organization. These  
situations may for example include:  
• Using the integrated wireless cards on board of airplanes, or in hospitals  
• In any other environment where the risk of interference to other devices  
or services is perceived or identified as harmful.  
If you are uncertain of the policy that applies on the use of wireless  
devices in a specific organization (e.g., airport or hospital), you are  
encouraged to ask for authorization to use wireless LAN PCI Express Mini  
Card or Bluetooth Daughter Card prior to turning on the computer.  
Safety information related to Mobile Broadband  
1
Do not use the Mobile Broadband feature on your computer in highly  
flammable areas (e.g. gas station) or near blasting. Though it is rare,  
the Mobile Broadband module, like other cellular network devices,  
could generate a spark.  
2
Avoid using Mobile Broadband feature outdoors during a  
thunderstorm.

Appendix E. Notices  
3
Use of mobile devices on board aircraft is explicitly prohibited by many  
airlines companies, especially during take-off and landing. The built-in  
Mobile Broadband module on your computer is a low-power radio  
transceiver. When it is turned on, it intermittently receives and transmits  
radio frequency (RF) energy which could cause interference with the  
operation of the airplane communication or navigation system. Refer to  
rules or regulations of your airline company for Mobile Broadband use.  
Never enable Mobile Broadband feature on your computer unless you are  
explicitly permitted to do so.  
4
5
Follow restrictions when using your computer in hospitals. Some  
equipments in hospitals are sophisticated and are susceptible to  
electromagnetic interference. Do not enable Mobile Broadband feature near  
medical equipment without requesting permission.  
The Mobile Broadband communication may affect the operation of  
implanted cardiac pacemakers and other medically implanted equipment.  
Patients with cardiac pacemakers should be well aware that use of Mobile  
Broadband feature on this computer may cause the implanted device to  
malfunction. If patients have any doubt that there is interference taking  
place, immediately disable the wireless radio on the computer and contact  
the doctor for more information.  
6
The Mobile Broadband module embedded in your computer does not  
support voice calls, hence their use for essential communications is not  
possible. Therefore you should never rely upon the device for essential  
communications.

EU WEEE statements -----------------------------------------------------------------  
The Waste Electrical and Electronic Equipment (WEEE) mark applies only  
to countries within the European Union (EU) and Norway. Appliances are  
labeled in accordance with European Directive 2002/96/EC concerning  
waste electrical and electronic equipment (WEEE). The Directive  
determines the framework for the return and recycling of used appliances  
as applicable throughout the European Union. This label is applied to  
various products to indicate that the product is not to be thrown away, but  
rather reclaimed upon end of life per this Directive.  
Users of electrical and electronic equipment (EEE) with the WEEE  
marking per Annex IV of the WEEE Directive must not dispose of end of  
life EEE as unsorted municipal waste, but use the collection framework  
available to them for the return, recycle, recovery of WEEE and minimize  
any potential effects of EEE on the environment and human health due to  
the presence of hazardous substances. For additional WEEE information

California Perchlorate Information:

Notice on deleting data from your hard disk----------------  
As computers spread into every corner of life, they process more and more  
information. The data on your computer, some of it sensitive, is stored on  
a storage device called the hard disk. Before you dispose of, sell, or hand  
over your computer, you need to delete that data.  
Handing your computer over to someone else without deleting the loaded  
software, such as operating systems and application software, may even  
violate License Agreements. You are advised to check the terms and  
conditions of those Agreements.  
Deleting the data from the hard disk is not easy.  
There are methods that seem to delete the data:  
• Move the data to the recycle bin, and then choose the Empty recycle bin  
command.  
• Use the Delete command.

Appendix E. Notices  
• Format your hard disk, using the software for initializing it.  
• Using the preinstalled recovery program, bring the hard disk back to  
factory-ship state.  
These operations, however, only change the file allocation of the data; they  
do not delete the data itself. In other words, the data retrieval processing is  
disabled under an operating system such as Windows. The data is still  
there, even though it seems to be lost. Thus, it is sometimes possible to  
read the data by use of special software for data recovery. There is a risk  
that people of bad faith may read and misuse the critical data on hard  
disks for unexpected purposes.  
To prevent the leakage of data, it becomes very important that you take  
responsibility for deleting all the data from the hard disk when you  
dispose of, sell, or hand over your computer. You can destroy the data  
physically by smashing the hard disk with a hammer, or magnetically by  
means of strong magnetic power, thus making the data unreadable. But  
we recommend that you make use of the software (payware) or service  
(pay service) specifically developed for the purpose.
