1.8.2 Battery Charging Control
Battery charging is controlled by a power supply microprocessor. The power supply
microprocessor controls power supply and detects a full charge when the AC adaptor and
battery are connected to the computer.
Battery Charge
When the AC adapter is connected, normal charging is used while the system is
turned on and quick charge is used while the system is turned off. Refer to the
following Table 1-11.
Table 1-81 Time required for charges of main battery
Condition Charging Time
Power On Charge About 6 hours
Power Off Charge About 3 hours
Charge is stopped in the following cases.
1. The main battery is fully charged
2. The main battery is removed
3. Main battery or AC adapter voltage is abnormal
4. Charging current is abnormal
Data preservation time
When turning off the power in being charged fully, the preservation time is as
following Table 1-12.
Standby About 3 days
Hibernation About 1 month
