User Guide

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.

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).

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.
