Real Time Clock (RTC) Battery

Main Battery

The main battery pack serves as the computer's main power source when the AC adapter is not
attached. The main battery maintains the state of the computer so that it can resume it.
1.5.2 Battery Charging Control
Battery charging is controlled by EC KB926. When the AC adapter and battery pack are attached
to the computer, the EC KB926 controls the charge on/off state and detects a full charge.
Battery Charge
When the AC adapter is attached, the battery is charged by off-state charge when the system
is powered off or by on-state charge when it is powered on.
Off-State Charge
On-State Charge
NOTE: The time required for normal charge depends on the power consumption by the
system. Using the fluorescent lamp and frequently accessing the disk consume much power
and lengthen the charge time.
