This is post is long overdue. No one is going to read this, so I’ll give you the short, short version.
I spilled coffee into my keyboard. The right half stopped functioning.
I read blog posts insisting that you can put a keyboard in the dishwasher.
The left side continued working correctly after the wash, to my amazement, but it did not fix the problem.
The dishwasher miraculously didn’t damage the keyboard, but it didn’t fix the coffee corrupted problem, as I read that it would.
I bought a new one.
