    Unhappy Return to sleep - Idle Timeout

    Dear Vista gurus,

    I'm suffering a very odd problem with waking up a PC from hibernation.

    I have an older PC that I've dropped in some drives to use as a backup server. It has Vista Ultimate 32 bit (OEM) installed.

    I want to wake up the PC at defined intervals so that back-up scripts can copy my changed files over the network for this back-up function.

    I've set up two scheduled tasks that run 3 times a day, (Morning, Afternoon, and late Evening). These two tasks switch on the PC, then shut it down at an arbitary point when I expect the backup to have completed.

    PC wakes up and nods off fine on the scheduled tasks, however when the PC wakes up it goes back to sleep within 2 minutes every time.

    The same happens if I wake the PC by a single touch of the mouse button or keyboard.

    If I power up the PC by hand, or touching the keyboard and then doing something, even just moving the mouse once I get to the log on screen the PC keeps running. Because of this, I've put all my attention into the "Return to sleep - Idle Timeout" values.

    I checked the registry as below:

    Balanced Power Scheme
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0\DefaultPowerSchemeValues\381b4222-f694-41f0-9685-ff5bb260df2e\

    High Performance Scheme
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0\DefaultPowerSchemeValues\8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c\

    Power Saver Scheme
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0\DefaultPowerSchemeValues\a1841308-3541-4fab-bc81-f71556f20b4a\

    Values Tried without effect:
    ACSettingIndex = 0 (Unlimited),21600 (six hours),86400 (Twenty Four Hours)
    DCSettingIndex = 0 (Unlimited),21600 (six hours),86400 (Twenty Four Hours)

    For each of these I have also tried restoring the power schemes to their default settings first before trying the new values, nothing appears to be working as expected, and the PC continues to return to hibernation after 2 minutes.

    I know that the ACSettingIndex and DCSettingIndex keys exist in many other devices, however withut understanding the effect, I'm loath to interfere with these other timeout values.

    Can anybody shed light on what is happening and how to get the PC to remain awake once I ask it to wake up.

    Many thanks for any advice or ideas as to where I might look next.

    Please no scrap Vista and get a real OS suggestions, I've already thought of that one

    Hi Bubtub,

    Many thanks for the screenshots, but I'm long past the standard settings screens. My version of Vista is simply not following the setting, either defaults, or through manipulation of the registry.

    Thanks for taking the time, but I've bounced it up to microsoft's Technet to see if they know what to do next.

    Best wishes,
    D.
