Charge the battery
When the battery power is low, charge your battery by connecting your computer to ac power.
The battery is fully charged in about four to eight hours. The actual charging time depends on the battery
size, the physical environment, and whether you are using the computer. If the power adapter shipped with
your computer supports the rapid charge function, the battery is 100% charged in about 2 hours when the
computer is turned off.
Battery charging is also affected by its temperature. The recommended battery temperature range for
charging the battery is between 10°C (50°F) and 35°C (95°F).
Note: To maximize the life of the battery, the computer does not start recharging the battery if the remaining
power is greater than 95%.
Maximize the battery life
• Lower the brightness of the computer display.
• Turn off the wireless features when not in use.
• Use the battery until the charge is depleted.
• Recharge the battery completely before using it.
