the annoying thing is, just before 12 month warranty ended, in Dec 2023, i returned the Surface, complaining about poor battery performance. they either fixed it (or, most likely, gave me a replacement refurbished unit). i am 90% certain they returned my model to me. maybe i should cut my losses and quit. except I'm committed to a massive coastal erosion project on my land. so money is too tight to mention 🙂
