Power States and Targeted System Power Global States G0 - working state G1 - sleeping state G1 - sleeping state G1 - sleeping state G2/S5 G3 - mechanical off AC power is disconnected from the computer. Sleeping States S0 - working S1 - Processor stopped S3 - Suspend to RAM. Context saved to RAM. S4 - Suspend to disk. Context saved to disk. S5 - Soft off. Context not saved. Cold boot is required. No power to the system. Processor States C0 - working C1 - stop grant No power No power No power Device States D0 - working state. D1, D2, D3 - device specification specific. D3 - no power except for wake-up logic. D3 - no power except for wake-up logic. D3 - no power except for wake-up logic. Targeted System Power (Note 1) Full power > 30 W 5 W < power < 52.5 W Power < 5 W (Note 2) Power < 5 W (Note 2) Power < 5 W (Note 2) No power D3 - no power for wake-up logic, except when provided by battery or external source. No power to the system. Service can be performed safely. Notes: 1. Total system power is dependent on the system configuration, including add-in boards and peripherals powered by the system chassis' power supply. 2. Dependent on the standby power consumption of wake-up devices used in the system. 1.13.1.2 Wake-up Devices and Events Table 13 lists the devices or specific events that can wake the computer from specific states. Table 13. Wake-up Devices and Events These devices/events can wake up the computer... LAN Modem (back panel Serial Port A) PME# signal Power switch PS/2 devices RTC alarm USB ...from this state S1, S3, S4, S5 (Note) S1, S3 S1, S3, S4, S5 (Note) S1, S3, S4, S5 S1, S3 S1, S3, S4, S5 S1, S3 Note: For LAN and PME# signal, S5 is disabled by default in the BIOS Setup program. Setting this option to Power On will enable a wake-up event from LAN in the S5 state. 34
