To charge a new battery:
●
Charge the battery while the computer is plugged into external power through the AC adapter.

faster while the computer is off. Charging may be delayed if a battery is new, has been unused for 2
weeks or more, or is much warmer or cooler than room temperature.

●
Blinking: The battery has reached a low-battery condition and is not charging.
●
Blinking rapidly: The battery has reached a critical low-battery condition and is not charging.
●
Off: The battery is fully charged or not installed.
