    Good day team. I have a Lenovo Thinkpad T450 Model.


    I just updated it from version 1903 to version 1909 yesterday. Before this update, it charges to 100% i.e both the internal battery and the external battery.


    After the update yesterday, it can no longer charge up to 100%.


    Please l need help.

    The system is windows 10 pro., 16GB of Ram, and

    256GB SSD

    Battery cannot charge more than 74%

    Acer battery won't charge

    What if the battery unremoveable? Should I disassemble and remove it? also there is a switch underneath the case and around the RAM slot that prevent the laptop to turn on when the case is open and without the charger. Is that the same as removing the battery? although when turned on with charger, the laptop still see the battery. Thanks

    - - - Updated - - -

    I took the report, the design capacity was 41.440 mWh but full charge capacity is now 25.752 mWh. Is it that bad? Before this happened I believe HWMonitor also show the same number with 38% Wear Level.
    Here's the report file
