User Guide 25
Problem: You need to install or uninstall a program.
Problem resolution:
During installation never abort the install process by powering the system off or
through other drastic means. This can cause system program disorder or even
failure during system initialization.
During the uninstall process, never directly delete the files or folders. This is
harmful to the system, and might cause a system-wide malfunction.
Use the following procedure to properly uninstall programs:
1. Back up all documents and system settings related to the program before
removing it.
2. If the program has its own uninstaller, run it directly to uninstall the program.
3. If the program does not have its own uninstaller, then select Control Panel from
the Start menu.
4. From the Control Panel, choose Programs and Functions.
5. Find the applicable program from the Programs and Functions dialog box and
then select Uninstall/Modify.
6. Perform the instructions displayed to uninstall the software.
3.4 Troubleshooting Problems with Optical Drives and
Hard Disks
Problem: The Optical drive is unable to read a CD/DVD.
Troubleshooting and problem resolution:
1. Check to determine if there is an optical drive icon in the resource manager
of the operating system. If not, restart your computer. If there is still no icon,
contact Lenovo Service. Otherwise, continue with the next step of this
procedure.
2. Confirm that the CD/DVD has been properly placed in the drive. If not, reload
the CD or DVD. Otherwise, continue with the next step of this procedure.
3. Check the specifications that came with your computer to confirm that this
optical drive is capable of reading this type of CD or DVD.
4. If the CD/DVD cannot be read, replace it with a known good CD/DVD such as
one that was shipped with the computer.
5. If the known good CD cannot be read, visually check the operating side of the
CD/DVD for defects.
26 User Guide
Problem: The capacity of the hard disk, as indicated by the system, is less than
the nominal capacity.
Troubleshooting and problem resolution: For computers equipped with the
OneKey Recovery feature, the system recovery feature needs to occupy some
hard disk space. This may account for the apparent hard disk capacity deficit.
Further Technical Explanation: The nominal capacity of the hard disk is
expressed in the decimal system, 1000 bytes. But the actual hard disk capacity is
expressed in the binary system as 1024 bytes (For example, the nominal capacity
1G is 1000M, while the actual capacity 1G is 1024M).
The capacity of the hard disk shown in Windows can be calculated according to
the calculations in the following example:
The nominal capacity of the hard disk is 40G, while its actual capacity
should be: 40 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 37G.
If the Service partition of 3G - 3 x 1000 x 1000 x 1000/(1024 x 1024 x 1024)
= 2.79G is subtracted, the capacity of the hard disk shown in the system
can be obtained.
The capacity of the hard disk as calculated using this method may be slightly
different from the actual capacity due to the rounding of totals.
3.5 Special considerations for troubleshooting
Windows
Record the following information as it may be useful later when troubleshooting
system problems:
1. The serial number of the software. The serial number was shipped with the
computer and provided separately by the manufacturer. The Help Center is
unable to retrieve this number.
2. The drivers for this computer model only support the Windows 7 system.
3. When you use the Windows Media Center to watch TV, be particularly attentive
to the following:
•
In the following two situations, you must re-save a channel list:
a. When you change your TV signal from digital to analog, your saved
channel list for digital TV is deleted. When you want to watch digital TV
again, you must create and save a new channel list.
b. When you change your TV signal from analog to digital, your saved
channel list for analog TV is deleted. When you want to watch analog
User Guide 27
TV again, you must create and save a new channel list.
•
You must set the TV tuner input signal to analog before you can watch
Teletext programming.
3.6 Performing Daily Maintenance Tasks
Cleaning the computer components
Because many of the computer components consist of sophisticated integrated
circuit boards, it is very important to periodically clean the computer to prevent
dust buildup. The cleaning supplies you need to clean the components include:
a vacuum cleaner, a soft cotton cloth, clear water (preferably purified or distilled
water) and cotton swabs.
Attention: Before you clean your computer, disconnect the computer
from the electrical outlet. Clean your computer with a soft cloth
dampened with water. Do not use liquid or aerosol cleaners, which may
contain flammable substances.
Note: To avoid damaging the computer or display, do not spray cleaning
solution directly onto the display. Only use products specifically designed
for cleaning displays, and follow the instructions included with the product.
The following are general methods for cleaning the components:
•
You can use a soft cloth to remove dust on the surface of the computer, the
monitor, the printer, the speakers and the mouse.
•
•
You can use a vacuum cleaner to clean in otherwise inaccessible corners.
To clean the keyboard thoroughly, shut down the computer and scrub it gently
with a wet cloth. Do not use the keyboard until it is dry.
Do not do any of the following:
•
•
•
Allow water to enter the computer.
Use a heavily dampened cloth.
Spray water directly onto the surface of the monitor or inside the computer.
LCD monitors should be cleaned daily. Use a dry cloth to brush dust from the
monitor and keyboard every day. Keep all surfaces clean and free of grease stains.

This guide does not include procedures for the replacement of all parts. It is
expected that trained service personnel are already able to replace cables,
switches, and certain mechanical parts without the need for step-by-step
procedures.
Note: Use only parts provided by Lenovo®.
The description of the TV-Tuner card in this manual applies only to computer
models with a TV-Tuner card, and therefore does not apply to models without a

User Guide 31
Handling static-sensitive devices
Static electricity, although harmless to you, can seriously damage computer
components.
When replacing a part, do not open the anti-static packaging containing the new
part until the defective part has been removed from the computer and you are
ready to install the new part.
When handling parts and other computer components, the following precautions
should be taken in order to avoid static electricity damage:
•
•
Limit your movements, as movement can cause the build-up of static electricity.
Always handle parts and other computer components with care, and handle
adapters, memory modules, system boards, and microprocessors by their
edges. Never touch any exposed circuitry.
•
•
Prevent others from touching parts and other computer components.
Before replacing a new part, first place the anti-static packaging containing the
part against a metal expansion slot cover or other unpainted metal surface on
the computer for at least two seconds. This will reduce static electricity in the
package and your body.
•
•
When possible, remove the new part from its anti-static packaging and install it
directly into the computer without setting the part down. If this is not possible,
place the part on top of its anti-static packaging on a smooth, flat surface
before installing it.
Do not place parts on the computer cover or other metal surface.
