It is back! My laptop has returned from the dead! It took a week of drying, being screwed-open and some baterry-removing, but it’s back now. So far the only itchy point is that my spacebar is somewhat sticky. It feels heavier, somehow, than the other keys. But that’s all on me, I’d say.
I’m just glad it works again. I hadn’t really noticed how much I actually do on my laptop until it didn’t function anymore.
