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 
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.
