Figure 11. Processor Power States

G0 - Working

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

C0 – Active modeP0

Pn

C1 – Auto Halt

C1E – Auto Halt, Low freq, low voltage

C3 – L1/L2 caches flush, clocks offC6 – Save core states before shutdown

C7 – Similar to C6, L3 flush

G1 – Sleeping

S3 Cold – Sleep – Suspend to Ram (STR) S4 – Hibernate – Suspend to Disk (STD), Wakeup on PCHS5 – Soft Off – no power, Wakeup on PCH

G3 – Mechanical OFF

Note: Power states availability may vary between the different SKUs
