So, I just bought a new 15" MBA for my wife, using her current 13" 2021 MBA as a trade-in. Well, this morning when I went to charge up the old MBA so that we could migrate to the new MBA I discovered that neither of the USB-B ports is connection to charge. I've tried multiple cables and power adapters. Is there something else I can check for or try? If we can't get the old MBA to charge I guess we're screwed for migrating her data and using it for a trade-in. Any help is greatly appreciated.
