4.1 Restoring the System

The system can develop problems due to erroneous operation or the installation of
additional software. If software problems develop in the originally installed software,
you can restore the system by using system backup and restoration features.

Note: The existing system settings will change after restoration. Check the

settings of the restored system to ensure they match settings that may be
critical to your needs.

Use the following procedure to restore the software to a known functional level:

1. Click

Start → All Programs → Accessories → System Tools → System

Restore.

2. Choose either the recommended restore point, or select a different recovery
time from the pop-up box. Choose the latest date when the system was running
properly.

Click

Next to continue.

3. The system will start restoration. When all processes run to completion, the
system displays a message informing you that the restore operation has
completed successfully.

4.2 Backup and Restore

For security purposes, you can back up the system status before you install
additional software, or otherwise modify system settings. To back up the system
status, do the following:

1. Click

Start → All Programs → Maintenance → Backup and Restore.

2. Select the location for your backup. Click

Next and follow the instructions to

continue.

4.3 Cleaning Up the Disk

Do the following periodically to clean up the disks and possibly enhance your
computer’s performance:

1. Click

Start → All Programs → Accessories → System Tools → Disk

Cleanup.

4.4 Checking For, and Correcting Disk Errors

To properly maintain your system, you should periodically check for and fix hard
disk errors by doing the following:

1. Right-click the icon for the hard disk drive (HDD) that you want to reorganize,
then select Properties from the pop-up menu.

2. Select the

Tools tab, and then click Check Now.

3. Check your inspection items for the disk and click

Start.

Note: You cannot start error checking until the computer is restarted and

initialized.

4.5 Defragmenting the Disk(s)

Disk fragments are tiny unused storage areas scattered on the disk. The system
cannot directly reutilize these “blank” spaces and system performance can
decrease as system operations usually cause the number of unused storage gaps
to increase. To defragment your disk storage, do the following:

1. Right-click the icon for the hard disk drive (HDD) that you want to reorganize,
then select Properties from the pop-up menu.

2. Go to the Tools tab from disk Properties and select

Defragment Now.

3. Select the time and scheme to be used by the defragging program, then start
the defragmenting program. Depending on the amount of defragmentation on
the hard disk drive, this procedure can take a long time (sometimes more than
one hour).

4.6 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 around the computer
to prevent dust buildup. The cleaning supplies you need in order to clean the
components include: a vacuum cleaner, a soft cotton cloth, clear water (pure water
preferred) 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.

User Guide

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 that are 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 of computer.

Daily attention should be given to LCD monitors. Use a dry cloth daily to brush
dust from the monitor and keyboard. Keep all surfaces clean and free of grease
stains.

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
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.

5.4 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 supposed to be able to read 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, 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 x1000/ (1024 x 1024 x 1024) = 37G.

If the Service partition of 3G - 3 x 1000 x 1000 x 1000/ (1024 x 1024
x1024) = 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.

5.5 Special considerations for troubleshooting Windows

Record the following information that may later be useful in troubleshooting system
problems:

1. The serial number of the software. The serial number was shipped with the
computer and was 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 TV
again, you must create and save a new channel list.
