    windows 10 pro (1607)

    laptop will not wake for task from shutdown


    new windows 10 pro system, all updates installed
    lenovo p51s
    i7 7600


    checked BIOS for any related s3/s5 settings but did not see anything

    nothing in power settings about fast startup (to disable)

    turned hibernate off with powergfg.exe

    the laptop will wake from sleep to run the task, but will not wake from shutdown

    this is not our first windows 10 machine, so we feel we really went thru all the 'normal' things to check. but we'd appreciate any help.

    btw, it worked perfectly on the previous windows 7 and windows 10 machines. could it be this version of windows which came as a system image from lenovo? the previous win 10 machine had a retail license.

    Hi hicksville. Welcome to the TenForums @hicksville

    A machine will wake from Sleep or hibernation but no machine will wake from a Power Off state.

    If device is power off, shutdown, Windows is not running and therefore cannot track time.

    One exception. In BIOS, most machines, it can be set to power on at a preset time. But that's not a Windows function.

    Hicksville,

    You will probably also find that the Wake the computer to run this task setting in Task scheduler is not all it seems -

    #1 Wake from hibernation only works if AC power is connected despite any settings you have made in Task scheduler.
    #2 Wake from sleep obeys the Conditions you have set in Task scheduler regarding any need for AC power to be connected.

    I have never seen it documented anywhere but the #1 limitation has applied to every laptop I have owned. I assume there are other computers that do not have the limitation.

    Thanks you,
    I'm pretty sure we were shutting down the previous computer and waking it. But maybe not if you're absolutely sure windows won't wake from shut down.

    It's in a docking station with continuous AC power.

    I guess we'll have to live with letting it sleep all the time instead of using shut down at night

    Thanks!

    Hicksville,

    Since you have continuous AC, you can Hibernate it instead if you prefer.

    Thanks everyone,
    We set it to hibernate. I guess shut down is a relic from the past that don't need to do nightly anymore.
