Small bright dots appear on your TFT display when you
turn on your computer.
Small bright dots may appear on your screen display when you turn
on your computer. Your display contains an extremely large number
of thin-film transistors (TFT) and is manufactured using high-
precision technology. Any small bright dots that may appear on
your display are an intrinsic characteristic of the TFT
manufacturing technology. Over a period of time, and depending on
the usage of the computer, the brightness of the screen will
deteriorate. This is also an intrinsic characteristic of the screen
technology. When the computer is operated on battery power, the
screen will dim and you may not be able to increase the brightness
of the screen while on battery power.
