If Something Goes Wrong
Disk or storage drive problems
Small bright dots appear on your TFT displays when you
turn on your computer.
Small bright dots may appear on your screen displays when you
turn on your computer. Your displays contain an extremely large
number of thin-film transistors (TFT) and are manufactured using
high-precision technology. Any small bright dots that may appear
on your displays 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 screens will
deteriorate. This is also an intrinsic characteristic of the screen
technology. When the computer is operated on battery power, the
screens will dim and you may not be able to increase the brightness
of the screens while on battery power.
Disk or storage drive problems
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:
You are having trouble accessing a drive, or one or more files
appear to be missing.
Make sure you are identifying the drive by its correct name
(A: or C:).
