Touch Pad
page 19
Do not use benzene, thinner, or rubbing alcohol. Doing so may adversely affect the sur-
face, e.g., discoloration. In addition, do not use commercially-available household clean-
ers and cosmetics, as they may contain components harmful to the surface.
Do not directly add or spray water or detergent. If liquid enters the inside of the com-
puter, it may cause it to work improperly or be damaged.
Display
<Models with touchscreen>
Use the Soft Cloth included with the computer. (For more information, refer to “Suggestions
About Cleaning the LCD Surface” that come with the Soft Cloth.)
If the Protective Film becomes dirty or damaged, it may be time to replace your Protective
Film. The Protective Film is a disposable item. To find out the model number of your Protec-
tive Film, contact Panasonic Technical Support. (For more information, refer to the “Operating
Instructions” that come with the Protective Film.)
<Models without touchscreen>
Avoid using water when cleaning the panel. Ingredients included in water may leave residue
and reduce readability of the screen.
<When cleaning dust/dirt>
Avoid rubbing off dust/dirt with cloth since it may leave scratch on the screen.
Sweep dust/dirt with fine brush, then wipe it with “dry” soft cloth used for cleaning glasses.
<When cleaning oily surface>
Apply camera lens cleaner on a soft gauze and clean it with gentle force. Then, wipe with dry
soft cloth used for cleaning glasses.
CAUTION
Areas excluding the display
Wipe these areas with a soft cloth, after applying water or detergent diluted with water to the
soft cloth and firmly wringing out excess water.
Do not touch or use a touchscreen before you re-attach a Protective Film, as you may
leave a mark or a scratch on the touchscreen.
CAUTION
Saving Data on the Hard Disk
Do not expose your computer to shock.
Use care when handling your computer, shock may damage your hard disk or make your
software applications and data unusable.
Do not power off your computer while software applications are running or hard disk drive indica-
tor ( ) is on.
Properly shut Windows down to avoid problems.
Save all valuable data to floppy disks, etc.
Backing up data to floppy disks, etc. will limit damage should trouble occur to your com-
puter or should you inadvertently change or erase data.
Use the security function for all important data.

Hard Disk Lock
When the Hard Disk Lock is set to [Enable], it is impossible to read/write data from/to the
hard disk when the hard disk is installed in a different computer, since a password is also set
for the hard disk. When the hard disk is returned to the original computer, you can read and
write data as before. In this case, however, make the settings in the Setup Utility exactly the
same as they were before the hard disk was removed. (Note that this Hard Disk Lock does
not guarantee complete protection of data.) (
