Windows Suspend will enter s1 or S3? RRS feed

  • Question

  • Hi,

    I have a question to windows behavior on ACPI power state.
    If the system BIOS provide both \_S1 and _S3 method in ACPI DSDT table. Which power state will Windows  enter when click on suspend?

    Looked at the windows API, there is an API named SetSuspendState(), which you can assign windows to "suspend"  and "hibernate". But I am not sure which "S1" or "S3" when we choose to "suspend" the system. Are there any way to know which power state which windows will enter?

    Thanks in advance.
