Good day. I apologize in advance for Google translator, but still try to convey the essence of the issue.

There is a Predator PH517-51, windows 10 lives in it and at night the battery self-discharge is 3-5%. Hibernation, fast starts, sleep modes and so on - everything is disabled. If you pull the battery out of the laptop and put it separately - not a 1% self-discharge for a day is there, but if you turn off the laptop, then pull out the charge and leave it for the night - then when turned on there will be minus 3-5% of the charge.

Removed and reinstalled all the drivers for the battery, resetting its settings through the button on the bottom panel and so on - nothing helps.

    Generate a battery report and check you battery values just to make sure there is nothing wrong with your battery
    1. Hit Windows Button + X and select Command Prompt (Admin). This is the quickest way to open the Command Prompt as an administrator.
    2. Type in and enter: powercfg /batteryreport.
    3. Open the Battery report HTML file to view it.

  • Hi! This model lets you load some devices into usbs ports when the notebook is shutdown? If yes, try disabling the usb charger function in acer quick access!

    everything is turned off from usb - just pull out the power plug, turn off the laptop. In the morning you turn it on and you see minus 3-5% of the battery charge - and this doesn’t turn on the laptop from the battery, it spends power, and you even connect the laptop to the power supply and when you go into windows, you see that the battery is charging and its charge is 97-95 %

    I understood!! Even so, disable this function and take the test:

    Well, I turned off this function right now, here again I can throw off the report https://yadi.sk/d/4Z6VQ92Fdbz-EA

    And I also noticed such a moment - when the battery is charging, the charge is 30 000 mW, but as soon as the battery reaches 95%, the charge drops to 3 634 mW


  • Are there any other programs or games that require more computer performance and are running in the background? Did you try upgrading your notebook drivers with the free driverbooster version?

    nothing hangs in the tray and does not use power, and all drivers are updated via the driver booster - everything costs the last

    Thats because as soon as the battery reaches 95% , windows just trickle charges the battery to stop overcharging of battery and as a consequence prevents overheating of the battery.
    overheating of battery is not good and it significantly degrades the storing capacity of battery.

  • What colleague @Deejay_tech said is correct! Batteries are charged quickly up to 80%! From 80% to 100%, what is called slow loading occurs. That's why the last 20% take longer to load!
    However, after deactivating the usb charger and updating the drivers, is the battery still being discharged?

    make sure that the laptop is  completely shut down before closing the lid.
    during the shutdown process if you close the lid immediately after the display goes off then the laptop goes into sleep mode rather than shutting down.
    after the display goes off it takes some time  for the laptop to shut down.
    so one should close the lid only when the power light goes off.

    just seeking clarifications ....

    In general, with further search for the problem, I found the following: even if Acer Quick Access turns off the power to usb, then the power to the usb ports of type c (thunderbolt) even when the laptop is turned off, with the power supply turned off (only the battery remains), still goes 5 volts. Is it really my only problem?
  • Have you checked that your notebook is actually configured to shut down power options? What is the bios version of your notebook?

    BIOS version 1.16. I checked it both programmatically, through disconnection in the Acer Quick Access settings, and I measured it with a multimeter for power supply and with the laptop completely turned off - power is being supplied through the type c ports.
  • OK! Check the device manager if the USB ports are set to be turned off:

    Also try disabling fastboot on bios and fast start up on windows power options!

    yes it is disabled by default. I wrote in the first post that all quick starts, hibernations, sleep modes, etc. - are disabled.
  • Now try uninstalling the AC power adapter and battery drivers in the device manager:
