Battery Power
TIPS

Partial discharge/charge cycles are preferred compared to drain-
ing the battery completely and recharging.

Connect AC Charger, Vehicle Dock, or Vehicle Power Adapter when-
ever possible and at the end of each work day.
When to Replace the Battery
Over time the battery’s capacity gradually decreases. Replace
your battery if it no longer provides 80% of its original rated
capacity.
WARNING There is danger of explosion if the battery is
incorrectly replaced. Replace only with the same or equivalent
type recommended by the manufacturer. Dispose of used bat-
teries according to the manufacturer’s instructions.
Heat Considerations
The computer’s processor is designed to consume as little
power as possible. However, working in a hot environment or
working for long periods may raise the temperature. Your com-
puter takes the following steps to lower temperature:
1. The cooling fan turns on. You may hear the fan and feel air
coming from a vent on the left side of the computer.
2. If the temperature continues to rise, processor activity is re-
duced. You may notice a slight loss of performance.
3. To prevent damage, if the computer gets too hot, the processor
stops and the computer shuts down.
