I spilled water on my keyboard and it's acting weird. What should I do?

Mar 31, 2018
I have a Lenovo Ideapad and while using it, I accidentally spilled some water on the keyboard and the screen. I quickly cleaned it up, but then the keyboard became weird - for example, when I tried to write "a", it wrote adkdjj (or something like that) and the same thing happened with all the other buttons - it just writes a strange string of letters. I turned the computer off and now I can't use it, since there's a password and I can't type it normally.
If I wait long enough, will it work again? Or do I need to take it to a lab?
Thank you very much!
