A green line suddenly appeared on my laptop. It runs straight down, and sometimes it goes away. I don't really know what to do. Bending/twisting the screen gets the line to go away, at times. I don't really think that's good for the screen, so I try not to do it. I haven't dropped the laptop at all and the screen appears to be fine, with no obvious cracks. Can someone help me?

monitor is probably going bad. Try hooking up a different monitor up to the computer, one that you know works properly. If the same problem exists then its the video card, if the problem goes away then its the original monitor that is bad.
Most of the time it is due to a hardware issue like a video card or the screen itself.
When does the line appear? A. Is it there even with the monitor or laptop turned off? B. Is it there during the OS logo / boot screen or does it appear after the OS loads? C. If it is a monitor, with your system turned off go into the menu of the monitor by using the buttons on the front. Is the line there?
What you can do to try and fix it is.
1. Make sure you have all the latest drivers for your video card. 2. Change the resolution of the screen. 3. Change the frequency of the monitor.
If these do not fix your issue you may want to look at getting or borrowing a video card and replacing it if this system is a desktop. If this system is a laptop and the above does not fix the issue your best bet would be to put up with it or buy a new laptop to be honest.
Try connecting an external monitor to the Dell Inspiron 9300 and see if the vertical line is also present on the monitor. If the monitor display is fine, then your laptop’s LCD display panel is defective. If the monitor also displays the vertical line, then your problem is with either the video card or motherboard located inside your laptop. Not sure if the Compaq Presario has an external monitor plug, but if it does the above procedure can be applied to that one as well.
