Heat and product ventilation
Danger:
Computers, AC adapters, and many accessories can generate heat 
when turned on and when batteries are charging. Notebook computers 
can generate a significant amount of heat due to their compact size. 
Always follow these basic precautions:
When your computer is turned on or the battery is charging, the base, the 
palm rest, and some other parts may become hot. Avoid keeping your 
hands, your lap, or any other part of your body in contact with a hot 
section of the computer for any extended length of time. When you use 
the keyboard, avoid keeping your palms on the palm rest for a 
prolonged period of time. Your computer generates some heat during 
normal operation. The amount of heat depends on the amount of system 
activity and the battery charge level. Extended contact with your body, 
even through clothing, could cause discomfort or even a skin burn. 
Periodically take breaks from using the keyboard by lifting your hands 
from the palm rest; and be careful not to use the keyboard for any 
extended length of time.
Do not operate your computer or charge the battery near flammable 
materials or in explosive environments.

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.

Chapter 6. Safety, Use, and Care Information
73
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.

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 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.

Appendix A. Lenovo Limited Warranty
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.
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 for 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, 
Y550 UG V1.0_en.book  Page 88  Wednesday, December 10, 2008  4:51 PM

Appendix A. Lenovo Limited Warranty
89
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. remove all features, parts, options, alterations, and attachments not 
under warranty service;
2. ensure that the product or part is free of any legal obligations or 
restrictions that prevent its replacement; and
Y550 UG V1.0_en.book  Page 89  Wednesday, December 10, 2008  4:51 PM

90
Appendix A. Lenovo Limited Warranty
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. follow the service request procedures that your Service Provider 
specifies;
2. backup or secure all programs and data contained in the product;
3. 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. 
Use of personal information
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 A. Lenovo Limited Warranty
A warranty period of three (3) years on parts and one (1) year on labor 
means that Lenovo will provide warranty service without charge for:
a. parts and labor during the first year of the warranty period (or a longer 
period as required by law); and
b. parts only, on an exchange basis, in the second and third years of the 
warranty period. Your Service Provider will charge you for any labor 
provided in performance of the repair or replacement in the second and

Types of warranty service
1Customer 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

does not receive the defective CRU within thirty (30) days of your receipt of 
the replacement.
2On-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.
3Courier 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.
4Customer 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.
5Product Exchange Service

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 B. 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 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 
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:

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.
Y550 UG V1.0_en.book  Page 123  Wednesday, December 10, 2008  4:51 PM

124
Appendix D. Notices
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.
