When you are not using the serial, parallel, or VGA ports,
keep the port cover closed to prevent damage to the pins.
Occasionally clean the computer’s exterior with a soft,
damp cloth.
Occasionally clean the LCD screen using glass cleaner on a
soft cloth;
do not spray the cleaner directly onto the screen.
If your trackball is not working correctly, you may need to
clean it. Follow the instructions on page 2-8.
Protecting the Hard Disk
Observe these precautions to protect your hard disk and data:
❑

❑
Never turn off or reset the computer when the Hard Disk
Activity icon appears in the System Window. This icon
indicates that the computer is copying data to or from the
hard disk.
Never remove the hard disk drive when the computer is
on.
After turning the power off, wait 20 seconds before moving
the computer. This allows the disks in the drive to stop
spinning and the hard disk read/ write heads to lock in
place so you do not damage the drive.
Although the hard disk is very reliable, be sure to backup
your files regularly. Make copies of all your system and
program diskettes before copying them to the hard disk.
Caution
When traveling by airplane, be sure to take your computer
into the passenger compartment as carry-on luggage so it is
not stored in an unpressurized storage area.
