Handling
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.
Do not drop or hit your computer against solid objects.
Do not carry your computer when it is on.
Remove all cables before transporting your computer.
We recommend preparing a fully charged battery (and optional charger, if possible).
When transporting spare batteries inside a package, briefcase, etc., it is recommended that
the batteries be stored in a plastic bag.
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.
Always carry your computer with you w'hen traveling. Never check it in with luggage. For
use of the computer inside an aircraft, we recommend asking the airlines regarding their
policy on this issue.
It is a good idea to make backup copies on disks and carry them with you.
Do not leave a disk in the drive while transporting your computer.

ful to the surface.
Do not directly add or spray water or detergent.
If liquid enters the inside of the computer, it may
cause it to work improperly or be damaged.
A Characteristic of Transflective Display (Only for models with 12.1 type LCD)
Immediately after the computer is turned off or enters the standby mode, you may notice a
black pattern appearing temporarily at the edges of the display. This is a characteristic of the
transflective display and is not a malfunction.
