I have strange event happening on a DELL Vostro laptop with WinXP. He uses a LCD external monitor with laptop. The problem is that all the keys on the left side of keyboard (which includes the CRT/LCD function) does not work. However on the right side of keyboard, those function keys do work. How is it possible half the FN keys work and the other half does not? I assume this is a hardware problem. I have tried the shift-scroll lock, etc combinations and nothing rectifies the issue. Right now he cannot use the external monitor - which does work on another PC.
