8.3  Maintaining the LCD Quality 

When it comes to screen problems, heat plays a big part. After a good working 
session, the typical routine is to shut the machine and close the cover. But the 
display surface - no matter what type it is - and the components inside the 
computer radiates heat; when you close the cover, you trap the heat against the 
screen. Leave the computer's cover open for about ten minutes while the heat 
disperses. Make this a habit. 

You should also enable the power management of your computer to turn off 
the LCD power and display when the system is in inactivity for some time. 
Adding screen savers is also acceptable. 

Follow the safety guidelines mentioned earlier and how to clean your 
computer. 

8.4  Maintaining Your Hard Disk 

Losing your data has the same consequences as a system break down. Users 
must make it a habit of doing hard disk maintenance every week or so. Here is 
some maintenance you could do: 

•  Always back up your data files from your hard disk. 

•  Install the virus detecting program to monitor virus that could tamper 

your files. 

•  Use SCANDISK once in a while to correct any errors found in the 

directory and File Allocation Table. This will also free up space from any 
unused sectors. 

•  Never move or raise the computer while the hard disk is being accessed, 

most especially don't jar the hard disk as this may cause a hard disk crash.
