Power Consumption With Hybrid Shutdown?

    OK, Here is my little experiment:

    With my LP plugged in and Fast Start-up/Hybrid Shutdown enabled I shut it down (Hybrid Shutdown). I disconnected the power/charger cable then pulled the battery for a while, reinstalled battery, reconnected power/charger cable and hit the power button. Laptop went to fast start-up without any prompts just like it does if it was never disconnected from a power source. This would tell me that the hybrid shutdown results in no power consumption. Even though my laptop was void of any power source it restarted immediately just as it does when left on a power source. I may have answered my initial question but I don't have any technical data to document it.

    I dumped hybrid power down some time back. For me it was causing too many crashes/bluescreens after reboot and sometimes corruption. Since I have relied on fastboot only, no more such problems. Seems to boot just as quickly. My experience, yours may differ.

    There's an easy way to prove you wrong: put your computer (note that I say computer, not a laptop) to sleep or Hybrid Shutdown. When it appears to be off, remove your power cabble to simulate power loss for a few seconds then put it back and press the power button to attempt to wake it up/turn it on. First, you'll see your HDD led is on and not twinkling. You'll only get black screen with nothing on it. Then press the reset button and you'll get a pre-OS screen asking you to delete saved data from the disk. When you press Enter you'll get a normal startup.
    You can believe what you want but I stand by what I have said and I know what I am talking about thank you.

    Fast Start (Fast Boot) shuts down the computer in a hybrid fashion, that's why it starts faster than from a full shutdown. It's not hibernate and it's not sleep but a little bit of both. With Fast Start enabled you get the hybrid (variant) shutdown whether you want it or not.

    From Microsoft: https://msdn.microsoft.com/en-us/lib...(v=vs.85).aspx

    "To prepare for a fast startup, Windows performs a hybrid shutdown sequence that combines elements of a full shutdown sequence and a prepare-for-hibernation sequence."

    From all that I have read as well as my little experiment I think there is more reason than not to believe that with Fast Start enabled there is zero power consumption of a laptop on battery after shutdown. But sleep is a totally different matter.

    I am marking this thread as solved but additional comments are welcome.

    I really meant "hibernate" where I said "hybrid" but it all is a bit of smoke and mirrors IMO. If the OS is optimized for a fast start up I'm not sure any of these settings are that much better than a cold start.

    This tutorial contains a good explanation of Fast Startup.

    I tend to agree with you there. On my PC's, especially my desktop there is not a whole lot of difference between the Fast Start and Cold Start. I have never timed it but it just doesn't seem that much different, possibly a matter of seconds. Big Deal
