VAIO® Notebook User Guide
Using the computer in low temperature conditions may produce a
residual image on the screen. This is not a malfunction. When the
computer returns to normal temperature, the screen returns to
normal.
The screen becomes warm during operation. This is normal and does
not indicate a malfunction.
The LCD is manufactured using high-precision technology. You may,
however, see tiny black points and/or bright points (red, blue, or
green) that continuously appear on the LCD. This is a normal result
of the manufacturing process and does not indicate a malfunction.
