• Make sure the socket and any extension cords you may use can support
the total current load of all the connected devices.
• Though your AC adapter is suitable for universal international voltage, it
still requires a stable and continual power supply. Make sure the voltage
of the power source when connect the notebook computer to the power
outlet. If your are unsure of your local power specifications, consult your
dealer or local power company.

• An approved power cord has to be used for the notebook computer’s
power supply. For a rated current up to 6A and an equipment weight
more than 3 kg, a power cord not lighter than H05VV-F, 2G, 0.75mm2,

8.2 Cleaning Your Computer
When it is necessary to clean the plastic case and keyboard, use a soft, lint-free
cloth, slightly dampened with a mild detergent solution or use the contents of
any commercially available computer cleaning kit.
Never use alcohol, petroleum-based solvents, or harsh detergents to clean the
notebook. Also never spray any liquids directly on the computer case,
keyboard, or screen. If the liquid-crystal display (LCD) screen has become
smeared or dusty, clean the screen by first applying a mild glass cleaner to a
soft, clean, lint-free cloth, and gently wipe the glass. Never apply liquids
directly on the screen surface. Moreover, do not use paper towels to clean the
display screen. Paper can scratch the display screen matte.

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 a 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 (FAT). 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.

• Use hard disk maintenance programs like DEFRAG or Norton Utilities
SPEEDISK. These reorganize your hard disk by eliminating
fragmentation and improving your hard disk access time.
• Install a system password in your computer so others won't be able to use
the hard disk.
