Having a laptop screen turn white is one of the most
frustrating problems a user can experience since it prevents use of the laptop
to find a solution.
A white laptop screen indicates a serious problem with the
laptop's hardware, and no easy solution to this issue exists.
Just diagnosing this condition requires advanced computer
With this problem, the laptop itself will power on and
load the operating system as per usual, but the screen will become a complete,
