1.	Solve : blue lines on screen?
Answer» Dell E1405 INSPIRON. When i was typing on laptop the screen became unstable&ID touch it and it would come back. Decided to restart. Came on with blue lines vertical with a black area on right side about an inch wide. What can I do? Tx in advance! To eliminate some possibilities or produce some. Using the external ports of the laptop connect an external monitor (or equipped TV) can be via VGA or HDMI connection cable and observe and report what the screen of the connected device displays. This will help to know whether the issue is video card based within the computer or is the laptop screen.truenorthSince touching the screen can toggle from a good image to bad, it SOUNDS to me LIKE a loose wire or a bad screen
