00h - S0/G0 “Working” 01h - S1 “Sleeping, system h/w and processor context maintained” 02h - S2 “Sleeping, processor context lost” 03h - S3 “Sleeping, system h/w and processor context lost, memory
maintained” 04h - S4 “non-volatile sleep or suspend to disk” 05h - S5/G2 “soft off” 06h - S4/S5 soft-off, particular S4/S5 state cannot be determined. 07h - G3 “Mechanical off” 08h - Sleeping in an S1, S2, or S3 state, particular state cannot be
determined. 09h - G1 sleeping, S1-S4 state cannot be determined 0Ah - S5 state entered by override 0Bh - Legacy on state 0Ch - Legacy off state 0Eh - Unknown
