several thin vertical lines have appeared on my laptop screen any suggestions how to rectify this?

Answer 1

I have this on my laptop at work. If it's a Dell, then it's a known issue, as I just discovered. They'll replace the screen as long as it's still in warranty. They may even replace it if its out of warranty.

However, the other posters are correct when they say you can't do anything about it. However, if you want to get technical it's not dead pixels. This is being caused by something else in the screen that feeds that column of the image instruction on what each color pixel should be in order to create your image.

Answer 2

This could be the video card is malfuntioning. If it is built into the Mother Board, the whole mother board has to be replaced.

A more likely cause would be the connections to the screen are loose or defective.

Take your fore finger and thumb, gently pinch the frame on the left and right side of the screen.

If some of the lines dissappear or the screen goes blank, the connections are loose.

If some of the lines dissappear or the screen goes blank, the connections are defective.

If it is under warranty, call for service and say the screen goes blank white occassionally.

This way they will likely replace the screen.

If it is not under warranty, it is not worth replacing. The screen will cost as much or more as a new laptop.

Good Luck
