1.6  Batteries 

The time required for normal charge is affected by the amount of power the system 
is consuming. Use of the fluorescent lamp and frequent disk access diverts power 
and lengthens the charge time. 

Using quick charge, the power supply microprocessor automatically stops the 
charge after eight hours regardless of the condition of the battery.  Overcharging 
could cause the battery to explode. 

If any of the following occurs, the battery quick charge process stops.  

 

1.  The battery becomes fully charged.  

2.  The AC adaptor or battery is removed.  

3.  The battery or output voltage is abnormal.  

4.  The battery temperature is abnormal. 

5.  The battery SMBus communication fails. 

6.  The battery cell is bad. 

?  Detection of full charge 

A full charge is detected from the battery pack through SMBus when the battery is 
charging. 

 

The RTC battery provides power to keep the current date, time and other setup information in 
memory while the computer is turned off. The table below lists the charging time and data 
preservation period of the RTC battery. The RTC battery is charged by the adaptor or main 
battery, while the computer is powered on. 

Charging Time (power on) 

About 24 hours 

Data preservation period (full charge) 

1 month
