It happens, it's just an unavoidable part of the aging process for an LCD displaym and nearly any older laptop will have at least a couple dead pixels.

Most current LCD screens are based on active-matrix technology, which offers desirable qualities such as fast response time, good picture contrast, and a wide viewing angle. The active matrix display operates by having a thin-film transistor (TFT) embedded in every pixel -- each screen pixel is driven independently.

However, over time these transistors can wear out and die, leaving a pixel that is either blank or stuck on a particular color. There is no fix short of replacing the entire screen, a job which on many even slightly used units can meet or exceed the value of the entire laptop.

The best way to ensure that no pixels are sent to a premature grave is to follow "normal" laptop use-and-care precautions: Don't hit or tap the screen, don't allow the unit to be exposed to temperature extremes, and so forth.
