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.

Problems with the storage drive or with external media usually 
show up as an inability to access the drive or as sector errors. 
Sometimes a drive problem may cause one or more files to appear 
to have garbage in them. Typical problems are:

Make sure you are identifying the drive by its correct name 
(A: or C:).

Run Error-checking, which analyzes the directories and files on the 
storage drive and repairs any damage it finds. 

To run Error-checking:

From the Start screen, type computer.
