Maintaining the LCD Quality

Heat is the most common problem associated with the screen. After a lengthy work session,
the typical routine is to shut down the machine and close the cover, but the display surface
(no matter what type it is) and the components inside the computer radiate heat. So, when
you close the cover, you will then trap this heat up against the screen. Leaving the computer
cover open for about ten minutes while the heat disperses eliminates this potentially damag-
ing situation.
