    Hack/Bat/Crack to truly TURN OFF laptop??


    windows 10 seems to have exacerbated the tendency of last few years for hybrid systems to never Turn OFF completely... lots of threads, few remedies, and systems of various makes/architectures are afflicted. This condition renders many laptops/tablet/hybrids a liability for travelers and students. Put the fully-charged laptop in a briefcase, turned "off", and it will be dead/dying when you need it the most.

    Instead of the usual pointless round of thread pages with no solutions, let me ask this:
    Is there a way via script or hack or bat or ANYTHING that will OFF a system that has non-removable battery?

    think creatively guys!!
    thx

    Wait for it to shut down before closing the lid? Turn off Fast Boot/Fast Startup to prevent hybrid shutdown? Why the creative solution needed - for impatient people who can't plan their exit or be bothered to change settings?

    Windows 10 x86 14383 Insider Pro and Core 10240

    Control Panel\All Control Panel Items\Power Options\System Settings\ Power button and lid settings

    When I close the lid : ( on battery ) shut down

    If you want to just sleep the machine:

    When I press the power button: ( on battery ) sleep

    Wait until it sleeps before closing lid. (I'm guessing if sleeping, it will not send the shut down command.)

    Or enable hibernation, and just use that instead of sleep or shutdown. Hibernation uses the same amount of power* as shutdown, unlike sleep which will run down a battery in time. Hibernation is slower than sleep, but faster than full shut down.

    *Worn out batteries lose power, even if no energy is being drawn out of them during shut down.

    If your battery runs down while sleeping over periods less than a day, your battery probably needs replacing with a genuine new battery with more capacity. There are many inferior counterfeit batteries for sale out there - and some of them may explode, leak or become incendiary destroying your laptop in the process without warning.

    powercfg -h off from admin cmd prompt to disable hibernation, then shutdown.

    you're thinking that hibernation is invoking even when power-off [shutdown -s] is triggered?

    the powercfg -energy report has a number of issues identified, as is usually the case with many of the late model hybrids/notebooks. some will not resolve until Intel corrects some of its energy-management 'wares. What I am trying to do is force-shutdown every device in the system - nothing lives.

    one thing I tried that seemed to help a little, but very laborious, is to go to the troubleshoot menu and do selective startup, boot in safe mode, and power-off from there. though there is no precise way to measure the impact that I know of, observing batt drain compared to power-off from a normal account used in normal mode, it appeared to be way less drain. the caveat is that the batt was at about 5% when I tried that idea and the low charge state may have triggered measures not normally in play.
    There is a discussion on one of the dell support boards to the effect that the later revs [around time of win 10 release] of Intel DPTF are buggy, and Dell support recommended backrev to 9.xxx series. I don't see that idea yet on Lenovo forums but may give it a shot anyway.

    First of all, hybrid sleep does not use much power. I have left a laptop shutdown for more than 60 days and still had plenty of power left, so complaining that this "at risk" seems a bit of a stretch.

    Secondly, there are good instructions here:

    to those interested in hybrid sleep that may be of interest. it's not in question here.

    let me paste the original query of this thread: "Is there a way via script or hack or bat or ANYTHING that will OFF a system that has non-removable battery?"

    I'm thinking that the perhaps too-old Operating System [generic] understanding of system-level "shutdown" command is what should be effected, but in Windows 10 world maybe such is different.
    Windows 10 appears to have the same shutdown switches /options as 8.1.

    Windows 10, shutdown ? :

    What would be the crucial difference/distinction between the /s and /p switches? "Turn Off" sounds like a modified powerdown [intercepted by energy management utils?].
    If shutdown /s still means shutdown as it 'once was', does it make a diff whether it is run from an elevated command versus local? [admin account, non-Microsoft ID] ?
    so perhaps, as was the case in early Windows 8 world, one could write a bat file that would invoke cmd.exe, run shutdown -s -t 3 for instance. right?
