The keyboard issue was probably caused by the battery, which can be replaced, and the keyboard would have likely returned to normal after the battery replacement.
In fact, depending on the model, the battery replacement may well have also entailed replacing the whole top cover (including the keyboard).
come on now, let the poor girl have a new laptop to replace her (at least) 5 year old one. what are we doing here.
Interesting I will look at replacing the battery if that’s a possibility. Thanks!
