  1. Battery charging light red


    The battery charging light on my windows 11 laptop is red when it used to be blue. My laptop is an Acer Nitro 5. The laptop still works and still charges but i am concerned if the red charging light means something is wrong. I tried running the battery health degradation test and it showed the design capacity of 58,751 mWh but a full charge capacity of 52,375 mWh. I am unsure of what the numbers mean and what I should do. Any help is greatly appreciated. My laptop is an Acer Nitro 5

    :)
