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.

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.
