Troubleshooting Software Problems
Problem: You are unable to exit a running program normally.
Troubleshooting and problem resolution:
1. Press the Ctrl, Alt and Delete keys at the same time, then select the Task
Manager option from the pop-up dialog box.
2. Select the problem program, then click the End Task button.
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 problems or even
failure during system initialization.
During the uninstall process, never directly delete the files or folders. This is
harmful to the operating 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 Apps → Control
Panel from the Search charm.
4. From the Control Panel, choose Programs → Programs and Features.
5. Find the applicable program from the Programs and Features dialog box and
then select Uninstall/Change.
6. Perform the instructions displayed to uninstall the software.
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.
27
User Guide
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.
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 as 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.

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, pure 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

Handling static-sensitive devices
Static electricity is harmless to you, but it can seriously damage computer
components.
When you are replacing a part, do not open the antistatic package containing the
new part until the defective part has been removed from the computer and you are
ready to install the new part.
Take these precautions to avoid static electricity damage when handling parts and
other computer components:
• Limityourmovement.Movementcancausestaticelectricitytobuilduparound
you.
• Alwayshandlepartsandothercomputercomponentscarefully.Handle
adapters, memory modules, system boards, and microprocessors by the
edges. Never touch any exposed circuitry.
• Preventothersfromtouchingthepartsandothercomputercomponents.
• Beforeyoureplaceanewpart,touchtheantistaticpackagecontainingthe
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.
• Whenpossible,removethenewpartfromitsantistaticpackagingandinstall
it directly into the computer without setting the part down. When this is not
possible, place the antistatic package that the part came in on a smooth, level
surface and place the part on it.
