Hi Guys,
I have an Acer Swift 3 (SF314-52). I noticed that I have a drain when the pc is off (no stand-by, disabled fast start, disable usb charge from Acer quick settings)
The drain is around 2% every 24h. For example last week I didn't use the pc for 6 days and the drain was about 10%.
Is it normal or is the battery damaged?
Thanks in advance

Bruno

    Hi,
    You could try a battery reset, switch off the laptop, disconnect AC adapter and follow the instructions in the video, leave the laptop to rest for 15-20 mins before starting again, in addition to that you could also install HWmonitor and watch the battery wear level.

    Yes, battery shouldn't drain like you have described in a new laptop but it's not a serious problem, it may be a minor glitch and battery reset as in my previous post or reinstalling Microsoft ACPI Compliant Control method battery driver in Device manager might resolve this problem.

    Do the battery reset and check whether it improves, if not, go to Device manager, expand Batteries, right click Microsoft ACPI-Compliant Control method battery, uninstall the driver in Driver tab, reboot the laptop.

    When I do the battery reset, before restarting, do I have to plug again the AC adapter or not? The written instructions say yes, but the video says no!
    thanks

    Yes, do not connect the AC adapter as the video says.

    Hi, sorry for the late reply.
    I have done the reset andIi partially solved. When is 100% charged it doesn't loose anything, but when it is partially discharged still continue loosing a little bit of battery %.
    I hope this is a calibration problem, I will update the post.
    Happy Easter!
    Cheers

    Hi,
    Yes, you could try manual calibration, please follow the instructions here:https://www.howtogeek.com/172271/how-to-calibrate-your-laptops-battery-for-accurate-battery-life-estimates/

    [Swift SF315-41]

     When i shutdown the laptop by “Shutdown windows” or de command: Shutdown /s. The power drain is about 10% over 14 hours.

    So after 2 days i have seen a drain of 25%.

     

    There is a little hole under the laptop that simulates the disconnection of the battery.

    So what i did. I shutdown windows through te shutdown at the taskbar en when the laptop seems te be turnt of (no more light er spinning fans or harddisk) i take a paperclib en pushed that button to simulate the battery diconnection.  Result after 24 hours the power drain was less then 1% (the 1% can will be the power that was needed to start windows.

     

     

    So there is something what is no complete going down or of….. but what? I don’t now yet.
