Answer to: Vertical line on screen (possibly stuck pixels?): likely causes?Use a pixeometer to determine the pixel line number on the screen. If you are using a 100-110VAC switch over to a input of 220-240V AC but keep the output voltage from the adaptor to the laptop the same. Try again and after 3 to 4 hours , the line may disappear. If not you may have to change the LCD. Best of luck..
