Handling the Battery Packs

The battery packs furnished with the computer require reasonable care and handling to en-
sure efficient operation and maximum life. Periodically inspect the battery terminals and
the batteries for evidence of corrosion and oxide build-up.
To ensure that the battery packs endure for a normal life cycle, always observe the follow-
ing precautions when handling the battery packs:

Maintaining the LCD Quality

When it comes to screen problems, heat plays a big part. After a good working session, the
typical routine is to shut the machine and close the cover. The display surface (no matter
what type it is) radiates heat. When you close the cover, you trap the heat against the
screen. Make sure to leave the computer's cover open for about ten minutes while the heat
disperses, before closing the LCD.
T
Never turn the computer off when the hard disk is being accessed.
T
Never move or raise the computer while the hard disk is being accessed. Be
especially careful not to jar the hard disk during access; this can cause a hard disk
crash.
T
Acquire a hard disk maintenance program like DEFRAG under DOS, or Norton
Utilities SPEEDISK programs. These programs reorganize your hard disk by
eliminating fragmentation and improves the hard disk access time.

pounds, or extreme heat.
