State Transition
The sleeping states supported by G510 are only S1 and S5.
Table below shows the wake up events in each state.
The way to transfer system to S5 from S0 in ACPI OS. Use OS build-in function:
ACPI OS provide the interface to allow user directly execute this function.
The ways to wake up system from S5.
G3 ( Power Failure) & Auto Power Recovery
Power failure means the AC power is lost. In this state, only battery power exists. G510 uses
“Auto Power Recovery” to manage the AC power recovers in G3 state. It means that when AC power is
back in G3 state, the system will back to S5 state first and determine it should stay in this state or assert
the ONCTRL# to power on system. In our design, the system will remember the state that it loses
the AC power. Then it will back to the “remembered state” when AC is back.
Wake up Events States Can Wake From
RTC S5
Power Button S5
RI# S5
PME# S5

S0 to S5 ( G2 )
Item Description
Set Timer ACPI OS provide the interface to allow user directly execute this function.
Power Button When power button is pressed, PC87414 will issue an SCI ( via
SIO_WAKEUP).
Sleep Button When sleep button is pressed, CSB5 will issue an SCI( Not Implement).
S5 to S0
Item Description
Power Button When power button is pressed in S5, the ONCTRL# will be asserted
and system will power on.
PME# Whenever PME# is asserted by one of the PCI devices in S5, the
ONCTRL# will be asserted and system will power on.
RI Whenever RI is asserted from COM1 in S5, the ONCTRL# will be
asserted and system will power on.
RTC Alarm When an alarm condition is detected, the ONCRTL# will be asserted
and system will power on.
