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
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 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
