Resolving a low battery level
CAUTION: To reduce the risk of losing information when the computer reaches a critical battery level and has initiated Hibernation, do not restore power until the power light turns off.
Resolving a low battery level when external power is available
▲Connect one of the following devices:
●AC adapter
●Optional expansion product or docking device

Calibrating a battery
Calibrate a battery under the following conditions:
●When battery charge displays seem inaccurate
●When you observe a significant change in battery run time
Even if a battery is heavily used, it should not need to be calibrated more than once a month. It is also not necessary to calibrate a new battery.
Step 1: Fully charge the battery
WARNING! Do not charge the computer battery while you are onboard aircraft.
NOTE: The battery charges whether the computer is off or in use, but it charges faster when the computer is off.
