Resume standby timestamp ?? RRS feed

  • Question

  •  

    Hi, all.......................I have a question about  resume from S3 or S4.

    We use pwrtest.exe and event viewer  to  measure resume standby time.

    And  we find resume standby time is too long, resume from S3 is about 2.5~3 sec; and S4 is about 2 secs.  

    S3: DriverInitDuration 1922 m sec + BiosInitDuration 540 msec

    S4: DriverInitDuration 2192 m sec + BiosInitDuration 0 msec     

    But Microsoft strongly recommands the S3 resume duration should be < 2 secs.

    Because we don't know which driver consume the longest time during resume duration.

    So is there any tool to measure resume duration for each driver (complete power IRP)?

    Thanks in advance

  • hi Mark,

    can you provide me some information on windows APIs which gives these time stamp information? which gives below times by calling the API?

    S3: DriverInitDuration 1922 m sec + BiosInitDuration 540 msec

    S4: DriverInitDuration 2192 m sec + BiosInitDuration 0 msec
