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.
