dry soft cloth used for cleaning glasses.
Maintenance
This computer has been designed so as to minimize shock to the LCD and hard disk drive, the
leakage of liquid (e.g., water) on to the keyboard, etc., but no warranty is provided against such
trouble. Therefore, as a precision instrument, be extremely careful in the handling.
When carrying the computer, be sure to keep to the following:
Turn off the computer.
Remove all external devices, cables, PC Cards protruding from the computer (see figure on
the left), SD memory cards, and MultiMedia Cards before transporting the computer.
Do not drop or hit your computer against solid objects.
Do not carry your computer when it is on.
Do not place the computer upright or allow it to tip over. When the computer receives 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.
Do not leave a disk in the drive while transporting your computer.
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.
When transporting a spare battery pack inside a package, briefcase, etc., it is recommended
that it be placed in a plastic bag in order to protect its contacts.
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.
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.
