Power Supply The power supply unit provides many different voltages for the system board and performs the following functions: 1.  Power input monitor Checks whether the DC power supply (AC adapter) is connected to the computer. Checks whether the battery pack is connected to the computer. Monitors the DC power supply input voltage (AC Adapter output voltage). 2.  Power supply's internal control Turns on and off the battery pack charging power supply. Issues a charging current instruction to the PWM control IC of the battery pack charging power supply. Controls the supply of DC power supply input (AC Adapter output) to the power supply unit. Controls the supply of power to the system block (load/logic circuit side). Controls forced shutdown if the power supply malfunctions. 3.  Logic circuit control Instructs the gate array to enable/disable tuning the power on. Controls power-on/off operation. 4.  Status display Turns on the Power LED (in Green or AMBER). Battery indicator (in Green or AMBER or AMBER Flash). 5.  External interface Performs communication through the I2C bus (via the internal EC/KBC). Transfers the power supply operation mode. 6.  Output monitor Monitors the voltage output to the system block (load/logic circuit side). Monitors the voltage, over voltage, input/output current of the battery pack. Monitors the internal temperature of the battery pack. Monitors the supply voltage from the AC adapter. 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 Main Battery Pack 6 Cell  Lithium Ion  10.8 V  4000 mAh 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 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. 1.8.2  Battery Charging Control Battery charging is controlled by WINBOND 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. 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.
