Managing Battery Power
Charging time
Charging the battery takes about 2 hours to fully charge.
Battery life
With a full charge, battery life in Suspend mode is about 48 hours. If the computer is
in use, typical battery life can last up to 3 to 3.5 hours, depending on your level of
use and your power management settings (see page 1-14).
Optimum Charging
To get the longest battery operating time, continue charging until the OmniBook
battery is fully charged, indicated by the following:
Charging light on the front of the computer stops blinking.
Status panel battery indicator (up or down triangle) stops blinking.
Because of rounding, a battery indicator can show a full battery before it's fully
charged. The indicators stop blinking only when the battery is actually full.
You can continue working while the battery is charging.
