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
U150 User Guide V1.0_en.book Page 3 Monday, July 13, 2009 10:36 AM
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 turns orange.
• 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 Rescue under a
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 a 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 preinstalled software).
• You can use the Restore to factory default feature to restore the system
partition (C drive) back to the factory default, i.e., the state your
computer was when you purchased it. Make sure you back up any
critical data stored on the system partition (C drive) to other media, such
as another disk partition, CD/DVD discs or removable storage devices.

it on your local hard disk. You can back up your data to a CD, DVD, or
other removable disk. In addition, you can also create Windows recovery
disc(s) to boot and recover your system.
Notes:
• The backup process and creating recovery disc 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.
• For computers without an optical drive, an external optical drive is needed to
back up or to create a recovery disc.

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
62
U150 User Guide V1.0_en.book Page 63 Monday, July 13, 2009 10:36 AM
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.
63
U150 User Guide V1.0_en.book Page 64 Monday, July 13, 2009 10:36 AM
Appendix B. Use and care information
- 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.
„
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.
64
U150 User Guide V1.0_en.book Page 65 Monday, July 13, 2009 10:36 AM
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.

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.
66
U150 User Guide V1.0_en.book Page 67 Monday, July 13, 2009 10:36 AM
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, MultiMedia 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.

care, you can avoid common problems. The following sections provide
information that can help you to keep your computer running smoothly.
„
General tips for maintenance
1 Check the capacity of your hard disk drive from time to time. If the
hard disk drive gets too full, Windows® will slow down and might
produce errors.
2 Empty your recycle bin on a regular basis.
3 Use the Microsoft Disk Defragmenter on your hard disk drive on a
regular basis to improve data seek and read time.
• To free up disk space, uninstall unused application programs.
• Clean out your Inbox, Sent, and Trash folders from your e-mail client
program.
• At least once a week, make a point to back up your data. If critical data is
present, it is a good idea to perform a daily backup. Lenovo has many
backup options available for your computer. CD-RW drives or
CD-RW/DVD drives are available for most computers.
• Use or schedule System Restore to take a system snapshot periodically.

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.

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 and a hard-disk drive.

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

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.

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.
98
U150 User Guide V1.0_en.book Page 99 Monday, July 13, 2009 10:36 AM
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 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.
5 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.

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.

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.
