So I recently ran a battery diagnostic and I noticed that my designed battery capacity was 53,939 mWh and but its full charge capacity is at 17,129 mWh, which is about 32% of it. I am really worried about what's gonna happen to my laptop, as I did the mistake of having it always plugged in due to it not notifying me whenever it’s low bat and it turning it off so suddenly. My laptop is an acer aspire s 13 4gb ram intel i5 gen 7 core. Please give me any advice on what I can do with my laptop, (preferably having to take it to the computer shop the last option, since my parents might freak out if they found out)
