Charging the Battery
Each time you connect the computer to AC power or install a battery in a computer that is connected to AC power, the computer checks the
battery's charge and temperature. The AC adapter charges the battery (if necessary) and maintains the battery's charge.
The AC adapter needs from 2 to 3.5 hours (depending on whether the system is on or off) to fully charge a battery that has been completely
discharged. If two batteries are installed in the computer, the AC adapter charges the main battery first, then the second battery. (The second
battery is discharged first.)
For maximum battery performance, charge the battery only at normal room temperature. To charge the battery, perform the following steps:
1 Latch lock (unlocked position)
2 Battery
3 Latch release
NOTE: You can leave the battery in the computer as long as you like. The battery's built-in circuitry prevents the battery from
overcharging.
