Hey, I have an HP ProBook 445 G1 running Windows 7 Ultimate. Recently, I have noticed that a white vertical line has developed on my screen approx. 2 inches on the left side of the screen. I reckon that it is a hardware screen problem because sometime there are 2/3 small lines and when I gently touch the screen, it become thick or thin. How do I check this? Any help will be appreciated.
