Handling the Battery Pack
The battery pack furnished with the computer requires reasonable care and handling to ensure
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 pack endures for a normal life cycle, always observe the following
precautions when handling the battery pack:
! Do not drop the battery pack or subject it to excessive shock and vibration.
!
Do not expose the battery pack to direct sunlight, moisture, chemical compounds, or
extreme heat.
! Do not disassemble the battery pack.
!
Do not use the battery pack to power other devices.
!
Do not short the battery leads or connect the battery with reversed polarity.
!
Never attempt to charge the battery pack in any way other than as described in this manual
and the user’s guide.
!
Always charge the battery pack 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.
