I have Acer One Z1402 laptop. Its happened 2 days ago (the battery is normal before the date). It only can be turned on when plugged in. When I check the battery usage history/report using cmd, the battery full charge capacity before its happened is 22680 mWh. After its happens, the capacity is still same (22680 mWh). I checked it using Acer Care Center, it said the battery is OK. If the battery and charger is Ok, why it cannot charging.

    How old is the battery? As this laptop is 7 plus years old and if you haven't changed the battery then your battery needs replacing no matter what the battery report says. Otherwise, its the charging circuitry inside this laptop that is faulty which will need a technician to look at and fix.

    These are the oem Aspire One Z1402 batteries, The battery is a CELEXPERT-LiOn 3S1R -Acer part# is: KT.0030C.001-AS14A

    Its firstly happened on 2019 and I changed the battery, secondly on 2022 and changed the battery again and this is the third. But when on 2019/2022, the battery full charge capacity is not same as design capacity, but today (2023), the battery capacity is same as design capacity (the battery health said it is ok).

    Uninstall the 2 battery drivers with Device Manager:

    Reboot and let Windows reinstall the drivers. As your battery is almost new you have to do a complete charge cycle for Windows and BIOS to register the battery capacity, if you never did that all battery stats in Windows will be inaccurate: Drain the battery till the laptop turns off automatically (hibernates), plug-in the adapter and charge till the amber LED turns blue. Don't use the Acer Care Center options, especially the 80% battery charge limiter as that interferes with BIOS and Microsoft ACPI battery control protocol.
