My laptop is maybe 2 years old, its a Presario C300 widescreen. A dark spot appeared on the bottom right of the screen about the cursor wide. Its not a dead pixel and I don't think its burn in. It is way to dark. Pixels can be seen though it, but its under the surface. I am at a loss as to what to even call it to start to find a solution. It almost looks to me as if there was dirt under the screen.
