1.5 Power Supply 1 Hardware Overview DC IN LED (one color: green) • Green = indicates AC adaptor is connected Battery LED (two colors: orange and green) • Green solid = The battery is fully charged. • Orange = The computer is quick-charging the battery / The battery is low. 6. Power ON/OFF sequence When power is turned on or off, the EC starts the power on or off sequence. • SQ0-4 = power ON sequence • SQ5-B = power OFF sequence 7. Battery charging control The EC controls the following. • The quick charging ON/OFF • The detection of full charge 8. Detection of the low battery The EC detects the low battery point by the gas gauge. • LB10M= The system will be driven by the battery for 12 more minutes. • LB0 = The battery won't be able to drive the system after 3 minutes. • LB1 = The battery can drive the system only during the suspend process. • LB2 = The battery cannot drive the system. 9. New battery installation When a new battery is installed, the EC communicates with the E2PROM in the battery to read information of the newly installed battery. 10. Battery capacity calculation The EC reads battery remaining and percentage capacity from the battery through SMBus. Satellite M30X Series Maintenance Manual 1-13

Hardware Overview
DC IN LED (one color: green)
Green = indicates AC adaptor is connected
Battery LED (two colors: orange and green)
Green solid = The battery is fully charged.
Orange = The computer is quick-charging the battery / The battery is low.
6.
Power ON/OFF sequence
When power is turned on or off, the EC starts the power on or off sequence.
SQ0-4 = power ON sequence
SQ5-B = power OFF sequence
7.
Battery charging control
The EC controls the following.
The quick charging ON/OFF
The detection of full charge
8.
Detection of the low battery
The EC detects the low battery point by the gas gauge.
LB10M = The system will be driven by the battery for 12 more minutes.
LB0
= The battery won't be able to drive the system after 3 minutes.
LB1
= The battery can drive the system only during the suspend process.
LB2
= The battery cannot drive the system.
9.
New battery installation
When a new battery is installed, the EC communicates with the E
2
PROM in the battery to
read information of the newly installed battery.
10.
Battery capacity calculation
The EC reads battery remaining and percentage capacity from the battery through SMBus.
