extremely strong shock after falling, the hard disk or floppy disk drive, etc., may become
inoperable.
Do not carry the computer while the display is open, or carry it by gripping the display.
Do not put anything (e.g., a piece of paper) between the display and keyboard.
When taking an airplane, always carry your computer with you. Never check it in with
luggage. Before using the computer inside an airplane, we recommend asking the airlines
regarding their policy on this issue.
Do not leave a disk in the drive while transporting your computer.
When transporting spare batteries inside a package, briefcase, etc., it is recommended that
the batteries be stored in a plastic bag.
We recommend the following:
Preparing a fully charged battery pack (and optional charger, if possible).
Making backup copies on discs and carrying them with you.

Useful Information
Maintenance
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

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 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 Protective Film,
contact Panasonic Technical Support. (For more information, refer to the “Operating Instruc-
tions” that come with the Protective Film.)

Avoid using water when cleaning the panel.  Ingredients included in water may leave residue
and reduce readability of the screen.

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.

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
Security Center/Antivirus Protection
Use the Windows Security Center function to protect Windows from damage by computer
viruses, etc.
Windows Security Center
What is Windows Security Center?
The Windows Security Center allows centralized management of Windows security infor-
mation, and monitors antivirus measures and other Windows security settings to ensure
optimum safety.
Use the Windows Security Center function to protect your computer from damage by vi-
ruses, etc.
Select [start] - [Control Panel] - [Security Center] to display the current settings for the
following security functions.
• Windows Firewall
A security system for protecting the computer from unauthorized access via the Internet
or other external networks.

work, so that only approved data can pass through.
At the time of purchase, the Windows Firewall is set to be enabled. 
						

							23
Operation
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 indicator (
) 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.  (  “Security Measures”)
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.) (
  “Security Measures”)
Users are advised to purchase the latest versions of virus protection software and use
them regularly.
We recommend you run the software:
• When booting your computer.
• After receiving data.
We recommend that you check data received on disks or from external sources, such as data
downloaded from the Internet, e-mail, etc.  (For compressed files, uncompress them before
running a check).
Computer Viruses
Windows Update
You can use the latest patches and service packs for Windows with the following menus.
Do not apply “Driver Updates” even if a message to update a driver appears. If a driver
update is required, contact to Panasonic Technical Support. (
 page 44)
[start] - [All programs] - [Windows Update]• Automatic Updates
If your computer is connected to the Internet, this function regularly checks whether secu-
rity updates and other important updates have been made available, and automatically
installs these updates in their latest conditions.
• Virus Protection
This function regularly checks whether antivirus software has been installed in the com-
puter, and whether the version of that software is the latest version available.
Read the message, select 
 (red icon) on the taskbar, and make the appropriate settings.
This message, which the Windows Security Center (
 page 22) displays to confirm the security-
related settings regularly, will be displayed until the settings are made more properly.
If the message “Your computer might be at risk” is displayed
NOTE
This message does not indicate an error. You can use the computer while the message is
displayed. However, in order to operate the computer more safely, we recommend mak-
ing the appropriate measures to reduce damage from virus and other attacks, thus avoid-
ing the appearance of this message.

Operation
When Disposing of or Transferring Ownership of This Device
When disposing of or transferring ownership of this device, erase all data on the hard disk in order
to prevent the theft of hard disk data. Even if you delete data or initialize the hard disk through
normal Windows commands, data can still be read using special software. In order to erase all
data, either have the data erased by a specialist (at a charge) or use the hard disk data erase utility
(included) (
 page 41).  (Note that this hard disk data erase utility does not guarantee that data
will be completely erased.)
Also, note that if you transfer ownership of this device without deleting commercial soft-
ware that you have installed to the hard disk, you may be in violation of the licensing
agreement for that software.
When Changing Hard Disk Partitions
When using the hard disk backup function, divide the hard disk into partitions when a backup
area is created.(
 page 37)  If you divide the hard disk into partitions before creating the
backup area, the backup area cannot be created.
Useful Information
When Using Peripheral Devices
Pay strict attention to the following points to avoid damage to the computer, peripheral devices,
cables, etc.  Also, in addition to following this manual and the Reference Manual, carefully read
the instruction manuals for the peripheral devices being used.
Use only peripheral devices that conform to the computer’s specifications.
Connect the devices properly, paying close attention to the condition and position of the
connectors.
If a connection cannot be made easily, do not apply undue force; check once more to confirm
the condition and position of the connector (alignment of pins, etc.) .
If the connector has holding screws, fasten the screws firmly.
Do not carry the computer with cables attached, and do not pull on the cables forcefully.
To prevent theft of data or unauthorized access to the hard disk
via a wireless LAN.
If you plan to use wireless LAN functions, we recommend that you do so only after making
the appropriate security settings, such as for data encryption.
Wireless LAN (only for models with wireless LAN)
Do not power down your computer or press the disk eject button while the Multimedia
pocket device indicator (
) is on.
Doing so may damage the data on the floppy disk and render the floppy disk useless.
Use care when handling floppy disks.
To protect the data on your floppy disks or to prevent a floppy disk from becoming stuck in
your computer, avoid the following:
• Sliding the shutter on the floppy disk manually.
• Exposing the floppy disk to a magnetic field.
• Storing the floppy disk in locations prone to high temperatures, low pitched noise, damp-
ness, or dust.
• Applying more than one label on the floppy disk.
Confirm the contents of a floppy disk before formatting it.
Confirm that no important data is on the floppy disk, because all data on the floppy disk will
be erased.
Use the write-protect tab.
This is
 a must for preserving important data.  This prevents your data from being erased or overwrit-
ten.
