4.0 Power Management

This chapter provides information on the following power management topics:

• Advanced Configuration and Power Interface (ACPI) States

• Processor Core

• Integrated Memory Controller (IMC)

• Processor Graphics Controller

Figure 8. Processor Power States

G0 – Working

S0 – Processor powered on (full on mode / connected standby mode)

C0 – Active mode

C1 – Auto halt

C1E – Auto halt, low freq, low voltage

C3 – L1/L2 caches flush, clocks off

C6 – save core states before shutdown and PLL off

C7 – C6 + L3 cache flush

G1 – Sleeping

S3 cold – Sleep – Suspend To Ram (STR)

S4 – Hibernate – Suspend To Disk (STD), Wakeup on PCH

S5 – Soft Off – no power,Wakeup on PCH

G3 – Mechanical Off

* Note: Power states availability may vary between the different SKUs

C8 – C7 internal voltage removal from all power domains

C9 – C8+VCC input to 0V

C10 – C9+VR12.6 shut off or PS4

G2 – Soft Off
