    Change in Sleep Behaviour after re-install of Windows


    Further to my previous thread about problems getting PC out of sleep I have noticed a change in how the PC behaves when in sleep mode.
    Before the re-install I am sure the PC became totally dormant, but now the system fans continue running (haven't checked CPU fan) and the power LED keeps flashing.
    Or am I delusional?

    It sounds like your sleep state is now S1, and previously it was S3.
    Check your BIOS settings.

    I use S3, and don't like S1 for the reasons you see...fans run, light blinking...
    Here is a link about sleep states.

    Thanks David. :)
    During all my fiddling over the previous problem I must have inadvertently switched ACPI suspend from STR to POS.
    Everything back to normal now.

    If it's not Windows it has to be fingers.
