So I went to the computer place there to pick it up. Jamie wasn’t in, and since he’d done the repair himself, no one could tell me what exactly was wrong with it in the first place.
I can’t really decipher the jargon on the repair sheet, but this “MB damage” concerns me. Presumably “MB” stands for “motherboard.”
Anyway, this is what Jamie did. It cost $100. (Click on the image to make it bigger and more readable.)
I should be able to update again anyhow.
