The computer takes the following actions for a critical battery level:
●If Hibernation is enabled and the computer is on or in Standby, the computer initiates Hibernation.
●If Hibernation is disabled and the computer is on or in Standby, the computer remains briefly in Standby, and then shuts down and loses any unsaved information.
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 to an approved AC adapter.
Resolving a low battery level when a charged battery is available
1.Turn off the computer or initiate Hibernation.
2.Remove the discharged battery, and then insert a charged battery.
3.Turn on the computer.
Resolving a low battery level when no power source is available
▲Initiate Hibernation.
– or –
Save your work and shut down the computer.
Resolving a low battery level when the computer cannot exit Hibernation
When the computer lacks sufficient power to exit Hibernation, follow these steps:
1.Insert a charged battery or plug the computer into external power.
2.Exit Hibernation by briefly sliding the power switch.
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.
