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 80GB hard disk will appear as less than 80GB in the operating system. This  
discrepancy is not an error in hard disk installation nor any other problem, but a normal  
phenomenon for 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  
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 checking the battery icon in  
the notification area.  
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.  
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  
Notes:  
You are advised to insert the battery pack when using your computer to prevent small particles from  
entering the inside of your computer.  
To increase the life of the battery pack, the computer does not start recharging the battery immediately  
after it drops from fully charged.  
Charge the battery at a temperature between 50 °F and 80 °F (10 °C-30 °C).  
Full charge or discharge is not required.  
Removing the battery pack  
If you are not going to use the computer for an extended period of time, or if you need to send  
your computer to Lenovo for service, etc. remove the battery pack from the computer. Before  
removing the battery pack, make sure the computer has been shut down.

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).  
Using Lenovo OneKey Recovery (Within Windows operating system)  
In Windows operating system, double click the OneKey Recovery System Icon on the desktop to  
launch Lenovo OneKey Recovery.  
Within the program, you can back up the system partition on the hard disk drive, other storage  
devices, or by creating recovery discs.  
Notes:  
The backup process and creation of recovery discs may take some time, connect the AC adapter and  
battery pack to your computer.  
After the recovery discs are burned, please number them so that you can use them in the correct order.  
Computers without an integrated optical drive support the creation of recovery discs; however an  
appropriate external optical drive is needed to physically create the recovery discs.  
For more instructions, see the help file of Lenovo OneKey Recovery.  
Using Lenovo OneKey Rescue system (Without Windows operating system)  
In the event that the operating system cannot be loaded, follow the steps below to access  
OneKey Rescue system.  
Shut down your computer.  
Press the key to launch OneKey Rescue system.  
Within the program, you can choose to restore your system partition to the original factory  
status, or to a previously generated backup.  
Note: The recovery process is irreversible. Make sure to back up any critical data before using the recovery  
feature.

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 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.  
- 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.  
36  
Download from Www.Somanuals.com. All Manuals Search And Download.  
       
Appendix B. Use, and care information  
- 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 130°.  
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 sleep or hibernation mode, or turned off, before moving it. This  
will prevent damage to the hard disk drive and data loss.  
• 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.  
• 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, xD-Picture Card, 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 sleep or hibernation mode before the data transfer is complete. To do so might  
cause damage to your data.

Appendix C. Lenovo limited warranty  
This Lenovo Limited Warranty applies only to Lenovo branded hardware products you  
purchased for your own use and not for resale.  
This Lenovo Limited Warranty is available in other languages at www.lenovo.com/warranty.  
What this warranty covers  
Lenovo warrants that each hardware product that you purchase is free from defects in materials  
and workmanship under normal use during the warranty period. The warranty period for the  
product starts on the original date of purchase specified on your sales receipt or invoice unless  
Lenovo informs you otherwise in writing. The warranty period and type of warranty service that  
apply to your product are designated below under the section titled “Warranty information.”  
THIS WARRANTY IS YOUR EXCLUSIVE WARRANTY AND REPLACES ALL OTHER  
WARRANTIES OR CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT NOT  
LIMITED TO, THE IMPLIED WARRANTIES OR CONDITIONS OF MERCHANTABILITY  
AND FITNESS FOR A PARTICULAR PURPOSE. SOME STATES OR JURISDICTIONS DO  
NOT ALLOW THE EXCLUSION OF EXPRESS OR IMPLIED WARRANTIES, SO THE ABOVE  
EXCLUSION MAY NOT APPLY TO YOU. IN THAT EVENT, SUCH WARRANTIES APPLY  
ONLY TO THE EXTENT REQUIRED BY LAW AND ARE LIMITED IN DURATION TO THE  
WARRANTY PERIOD. NO WARRANTIES APPLY AFTER THAT PERIOD. SOME STATES OR  
JURISDICTIONS DO NOT ALLOW LIMITATIONS ON HOW LONG AN IMPLIED  
WARRANTY LASTS, SO THE ABOVE LIMITATION ON DURATION MAY NOT APPLY TO  
YOU.  
How to obtain warranty service  
If the product does not function as warranted during the warranty period, you may obtain  
warranty service by contacting Lenovo or an approved service provider. Each of them is referred to  
as a “Service Provider.” A list of Service Providers and their telephone numbers is available at  
www.lenovo.com/support/phone.  
Warranty service may not be available in all locations and may differ from location to location.  
Charges may apply outside a Service Provider’s normal service area. Contact a local Service  
Provider for location-specific information.  
What your service provider will do to correct problems  
When you contact a Service Provider, you must follow the problem determination and resolution  
procedures specified.  
Your Service Provider will attempt to diagnose and resolve your problem over the telephone,  
e-mail or through remote assistance. Your Service Provider may direct you to download and install  
designated software updates.

Appendix C. Lenovo limited warranty  
Some problems can be resolved with a replacement part that you can install yourself called a  
“Customer Replaceable Unit” or “CRU.” If so, your Service Provider will ship the CRU to you to  
install.  
If your problem cannot be resolved over the telephone or remotely, through your application of  
software updates or the installation of a CRU by you, your Service Provider will arrange for service  
under the type of warranty service designated for the product under the section titled “Warranty  
information.”  
If your Service Provider determines that it is unable to repair your product, your Service Provider  
will replace it with one that is at least functionally equivalent.  
If your Service Provider determines that it is unable to either repair or replace your product, your  
sole remedy is to return the product to your place of purchase or to Lenovo for a refund of your  
purchase price.  
Replacement of a product or part  
When the warranty service involves the replacement of a product or part, the replaced product or  
part becomes Lenovo’s property and the replacement product or part becomes your property. Only  
unaltered Lenovo products and parts are eligible for replacement. The replacement product or part  
provided by Lenovo may not be new, but it will be in good working order and at least functionally  
equivalent to the original product or part. The replacement product or part shall be warranted for  
the balance of the period remaining on the original product.  
Before your Service Provider replaces a product or part, you agree to:  
1
2
remove all features, parts, options, alterations, and attachments not under warranty service;  
ensure that the product or part is free of any legal obligations or restrictions that prevent its  
replacement; and  
3
obtain authorization from the owner to have your Service Provider service a product or part if  
you do not own it.  
Your additional responsibilities  
Where applicable, before service is provided, you agree to:  
1
2
3
follow the service request procedures that your Service Provider specifies;  
backup or secure all programs and data contained in the product;  
provide your Service Provider with all system keys or passwords and sufficient, free, and safe  
access to your facilities to perform service; and  
4
ensure that all information about identified or identifiable individuals (“Personal Data”) is  
deleted from the product or that, with respect to any Personal Data that you did not delete, you  
are in compliance with all applicable laws.

If you obtain service under this warranty, Lenovo will store, use and process information about  
your warranty service and your contact information, including name, phone numbers, address,  
and e-mail address. Lenovo will use this information to perform service under this warranty and to  
improve our business relationship with you. We may contact you to inquire about your satisfaction  
regarding our warranty service or to notify you about any product recalls or safety issues. In  
accomplishing these purposes, we may transfer your information to any country where we do  
business and may provide it to entities acting on our behalf. We may also disclose it where required  
by law.

Appendix C. Lenovo limited warranty  
If required, your Service Provider will provide repair or exchange service depending on the type of  
warranty service specified for your product and the available service. Scheduling of service will  
depend upon the time of your call, parts availability, and other factors.  
Types of warranty service  
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.  
2 On-site Service  
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.  
4 Customer Carry-In or Mail-In Service  
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.

Appendix C. Lenovo limited warranty  
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 paid by Lenovo. Failure  
to use the carton in which the replacement product was received may result in your  
responsibility for damage to the failed product during shipment. You may be charged for the  
replacement product if Lenovo does not receive the failed product within thirty (30) days of  
your receipt of the replacement product.

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.  
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 much  
less than the electromagnetic energy emitted by wireless devices such as 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 result from  
deliberations of panels and committees of scientists who 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.

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.

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.

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.

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.  
• 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.
