Dear All,

Could you please tell me the Windows XP/2000 ACPI mode mapping?


I only knew:


S0: Full speed running
S3: Suspend to ram
S4: Suspend to disk
S5: Off

But how is S1, S2 stand for in Windwos XP/2000? screensaver?

Thank you very much for your help.

Best regards,

Boki.
 
Hi,

A definition of the various power states:

S0 - Up and running

S1 - Standby. Drives, display off. Power still on to cpu, fans, ram

S2 - Standby. Same as S1, but cpu is powered down

S3 - Standby. Power only to refresh ram

S4 - Hibernate. No power, contents of ram copied to hard drive before
powerdown (hiberfil.sys)

S5 - System off.

Not all states are supported on all systems, and this is a somewhat
simplified view. Some systems, hardware, or combinations thereof will not
support any of these states.
