Why is my laptop isn't charging plus the system tray keep closing itse

Last week I spilled some water on the top of my laptop ( while it was folded). I don't think water went inside the laptop. But since that time the laptop start behaving wierd. First, I couldn't turn it on until the next morning, the charger indicator changed from orange to yellow. And it keeps switching OFF by it self.

And the system tray keep closing and I couldn't open any website or YouTube as it keep backward.

This all happened within just 24 hours of the water spillage accident
