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 normal life cycle, always observe the following pre-
cautions when handling the battery packs:
T
Do not drop the battery packs or subject them to excessive shock and vibration.
T
Do not expose the battery packs to direct sunlight, moisture, or chemical com-
pounds, or extreme heat.
T
Do not disassemble the battery packs.
T
Do not use the battery packs to power other devices.
T
Do not short the battery leads or connect the battery with reversed polarity.
T
Never attempt to charge the battery packs in any way other than as described in
this manual and the User's Guide.
T
Always charge the battery packs as soon as possible after a low battery indication.

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.
