I spilled water to my laptop. Dried it for a whole 24 hours, upside down, well, my laptop is back to work with no problems, except with a mark appearing on my lcd screen. This mark is most noticeable on white display, and when you tilt away from the viewing angle, the more you tilt the more visible it gets. I don't understand. No scratch noticed, no physical damage. What the !&&* is this, and how do you make it go away? Need help..
