Attaching the AC Adapter
Your computer runs on power from the battery in the computer or from an electrical outlet. The first time that you use your computer, fully charge the battery by attaching the power cord to the computer and to an electrical outlet.
All batteries lose their charge if they sit unused for an extended time period. When not used, battery can discharge fully in 2 to 3 months. The battery may have discharged in the time it took for the computer to go from the factory to you.
To attach the power cord:
1.Plug the AC adapter into the power connector on the back side of the computer.
2.Connect the power cord to the AC adapter and then to an electrical outlet.
AC Adapter
The battery starts charging as soon as you plug the power cord into an electrical outlet. The battery charges faster if the computer is turned off during charging.
If the battery is fully depleted and the computer is turned off, the battery charges in about 3 hours. If the computer is turned on, the battery charges in about 6 hours. When the battery is charging, the battery charge light is red. When the battery is fully charged, the light turns green.
See ”Using Power Management Options” on page 57 for more information on using your computer’s battery.
