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

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.

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: 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.  
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.
