●If you are charging a new battery, charge it fully before turning on the computer.
NOTE: If the computer is on while the battery is charging, the battery meter in the notification area may show 100 percent charge before the battery is fully charged.
●Allow the battery to discharge below 5 percent of a full charge through normal use before charging it.
●If the battery has been unused for one month or more, calibrate the battery instead of simply charging it.

Managing low battery levels
The information in this section describes the alerts and system responses set at the factory. Some
Identifying low battery levels
When a battery that is the sole power source for the computer reaches a low or critical battery level, the following behavior occurs:
●If Hibernation is enabled and the computer is on or in Suspend, the computer initiates Hibernation.
●If Hibernation is disabled and the computer is on or in Suspend, the computer remains briefly in Suspend, and then shuts down and loses any unsaved information.
