Specs: Windows XP Prof serv pk 3
I have a Dell Insiron 6400 laptop. It has verticle lines that appear to red,green and white at the far left side on monitor. Then it has a white verticle line with a red line in the middle of it about one and a half inch from the far left side. They run from top to bottom. The pointer for the mouse appears to go under the line closer to the middle. What can I do to clear these lines. All help is greatly appreciated. Thank you in advance.

If the lines appear while booting BEFORE the operating system loads, at any time, that cannot be caused by any software on the hard drive.
Even if they only appear AFTER the operating system loads, you probably have a hardware problem.

Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

See response 1:

DO NOT plug in or unplug a monitor's video cable into / from a video port while the computer is running. Doing so can damage the monitor's circuits and/or the video adapter's circuits.

Some laptops will display on an external monitor without you having to do anything.

If you get no video on an external monitor, some laptops have a key combo that you must press to toggle the display to external video only / built in display video only / sometimes both - see the Owner's or User's manual for the model.
