I have a Dell Inspiron laptop and I loaned it to my wife for a class in Visual Basic. Most of the time it works okay, but every once in a while the keyboard acts up and several of the keys don't work as they should such as the Backspace key or the Y key does not do anything when pressing those keys. So, I usually have to pull out a regular PS2 keyboard at that time and that keyboard works fine. I am suspecting that either one of the special key sequences was pressed by accident or the accessibility which I hate engaged itself somehow. Any ideas as to how to default it back to its original configuration?

Thanks,
