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 PC. Your display contains an extremely
large number of thin-film transistors (TFT) and is
manufactured using high-precision technology. Any small

and you may not be able to increase the brightness of the
screen while on battery power.
