1.7 Power Supply 1 Hardware Overview 
Satellite L300/L305/Satellite Pro L300/EQUIUM L300/SATEGO L300     Maintenance Manual  19 
1.7 Power Supply 
The power supply unit provides many different voltages for the system board and performs the 
following functions: 
1. Power input monitor 
y  Checks whether the DC power supply (AC adapter) is connected to the co\
mputer. 
y  Checks whether the battery pack is connected to the computer. 
y  Monitors the DC power supply input voltage (AC Adapter output voltage)\
. 
2.  Power supplys internal control 
y  Turns on and off the battery pack charging power supply. 
y  Issues a charging current instruction to the PWM control IC of the battery pack charging 
power supply. 
y   Controls the supply of DC power supply input (AC Adapter output) to the power supply 
unit. 
y   Controls the supply of power to the system block (load/logic circuit side). 
y  Controls forced shutdown if the power supply malfunctions. 
3.  Logic circuit control 
y  Instructs the gate array to enable/disable tuning the power on. 
y  Controls power-on/off operation. 
4.  Status display 
y  Turns on the Power LED (in Green or AMBER). 
y  Battery indicator (in Green or AMBER or AMBER Flash). 
5.  External interface 
y  Performs communication through the I2C bus (via the internal EC/KBC). 
y  Transfers the power supply operation mode. 
6.  Output monitor 
y  Monitors the voltage output to the system block (load/logic circuit side). 
y  Monitors the voltage, over voltage, input/output current of the battery \
pack. 
y  Monitors the internal temperature of the battery pack. 
y  Monitors the supply voltage from the AC adapter.  
						

							
1 Hardware Overview 1.8 Batteries 
20 Satellite L300/L305/Satellite Pro L300/EQUIUM  L300/SATEGO L300     Maintenance Manual 
1.8 Batteries 
The computer has the following four types of batteries: 
‰ Main Battery Pack 
‰  Real Time Clock (RTC) Battery 
Table 1-5 lists the specifications of these batteries. 
Table 1-5 Battery Specifications 
Battery Type Material Output voltage Capacity 
3 Cell Lithium Ion 10.8 V 2000 mAh 
6 Cell Lithium Ion 10.8 V 4000 mAh Main Battery Pack 
9 Cell Lithium Ion 10.8 V 6000 mAh 
RTC Battery Lithium Ion 3.0 V 14 mAh 
 
1.8.1 Main Battery 
The main battery pack serves as the computers main power source when the AC adapter 
is not attached.  The main battery maintain s the state of the computer so that it can 
resume it. 
 
1.8.2  Battery Charging Control 
Battery charging is controlled by WINB OND WPCE775L.  When AC adapter and 
battery pack are attached to the computer , the WPCE775L 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.

 Table 1-6 Quick/Normal Charging Time 
State Charge Time 
Off-State Charge 3/6/9 Cell About 4 hours max 
On-State Charge 3/6/9 Cell About  4~10 hours max 
 
NOTE: The time required for normal charge depends on the power consumption by\
 the 
system.  Using the fluorescent lamp and frequently accessing the disk co\
nsume much 
power and lengthen the charge time. 
Any of the following cases stops battery charge: 
1.  The battery becomes fully charged. 
2.  The AC adapter or battery pack is removed. 
3.  The battery or AC adapter voltage is abnormal. 
 
‰ Detection of full charge 
A full charge is detected only when the battery is being charged by quick or normal 
charge.  A full charge is detected when either of the following conditio\
ns is met: 
1.  The current in the battery charging circuit drops below the predetermined 
value. 
2.  The charging time exceeds the fixed limit. 
 
1.8.3 RTC Battery 
The RTC battery provides power to keep  the current date, time and other system 
information in memory while the computer is turned off.
