Maintenance
To clean the LCD panel
Use the Soft Cloth (included) with the computer. (For more information, refer to Reference Manual “Suggestions
About Cleaning the LCD Surface”.)
Cleaning the display while the power is on may cause the computer to malfunction. Also, dirt on the screen is easier to
see when the computer is powered off, and so is easier to clean.
To clean the touch pad
Wipe lightly with a gauze or other dry, soft cloth.
To clean areas other than the LCD panel and touch pad
Wet a soft cloth with water or a diluted kitchen cleanser (neutral), wring the cloth out thoroughly, and wipe the dirty
area gently. Using a detergent other than a neutral kitchen cleanser (e.g., a weak alkali cleanser) may adversely affect
painted surfaces.
CAUTION
Do not use benzene, thinner, or rubbing alcohol since it may adversely affect the surface causing discoloration, etc.
Do not use commercially-available household cleaners and cosmetics, as they may contain components harmful to
the surface.
Do not apply water or detergent directly to the computer, since liquid may enter inside of the computer and cause
malfunction or damage.
When Using the Computer with a Reduced Resolution
When setting the screen resolution to a resolution below the LCD’s resolution, the images appearing on the screen will
be stretched. As a result, the characters displayed may appear blurred. This is normal, and not indicative of a malfunc-
tion.
To display large characters with no blurring
Try the following steps while keeping the LCD in its resolution.
Click (Start) - [Control Panel] - [Appearance and Personalization] - [Display], select except for
[Smaller - 100%] and then click [Apply].
(This function will be enabled after logging off the computer.)
To display enlarged font sizes in applications such as Internet Explorer:
Use the display enlargement function provided by the specifi c software application.
To display enlarged desktop icons, title bar and cursor or magnify the specifi c part of the screen:
Use “Icon Enlarger” or “Loupe Utility”.
