I bought a new Macbook air in 2019 but I didn’t open it until September of 2020. While activating and upgrade the operating system. My laptop shows a dying battery. Eventually, it is not powering up or startup at all. I want to pay it off before I use it and I am not aware of the warranty beginning on the same day I placed the order with BestBuy. I replaced the battery from eBay and didn’t work. Now I am stuck with a brick that I don’t know what to do with it. Replacing the USB c port resolves the problem of no power at all?
