Ensuring Battery Gauge Accuracy
The built-in battery gauge, which displays the amount of charge
remaining, is precalibrated for accuracy. To ensure continued
battery gauge accuracy and to maximize battery operating time:
■
Fully charge the battery pack before the first time you use it.
■
Allow the battery pack to completely charge before removing
external power from the computer, convenience base, or
battery charger.
■
If the battery has been out of the computer for two weeks or
more, fully recharge the battery pack before using it.
■
Approximately every 60 days, allow the battery to completely
discharge to the low battery condition through normal use
before recharging it.
NOTE:
The various battery gauges available on your system should
be regarded as an approximate indication of remaining battery life.
Use the battery until the first warning is received, even if the
gauge indicates "no power."
Identifying a Low Battery Condition
When a low battery condition is reached, the computer beeps
twice approximately every five minutes, and the battery power
light blinks once per second. When a critical low battery
condition is reached, the computer beeps four times every five
seconds, and the battery light blinks twice per second.
CAUTION:
When you are alerted to a low battery condition, very
little battery charge remains. Take immediate action to resolve the
condition.
When a low battery condition is reached, save your files and
initiate Suspend. You have approximately 5 to 10 minutes to
resolve the low battery condition before the computer enters the
critical low battery condition.
When a critical low battery condition occurs and Hibernation is
enabled, the system initiates Hibernation.
CAUTION:
If Hibernation is disabled, the computer cannot initiate
Hibernation when a critical low battery condition is reached. If
Hibernation is disabled, the computer initiates Suspend until the
battery pack fully discharges. When this occurs, all unsaved
data is lost.
