I talked to a coworker at the tech company I work at and he thought it might be the LCD inverter. If you apply some pressure to the screen frame, the display will return to normal and the small vertical line will go away. He says he is pretty sure it is magnetic damage to the LCD; the computer itself appears to be working fine. If you have two RAM modules installed remove them one by one and test the laptop with each one. I doubt that lines on the screen could be related to a failed hard drive. I have disassembled and cleaned the laptop internally, it works fine on an external display crt , when i took it apart there was reminents of soup on the lcd video cable. Can you see the BIOS screen at all?
