I am using Windows XP on a Lenovo 3000 c100. I get a funny beeping noise that accompanies continuous backslahes in typing areas. (\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\). This will continue until I hit any key on the keyboard, but will resume when opening any window or typing area. I have removed and reseated the backslash button but that did not work. Anyway, I know that is not the problem. I have applied a registry fix that appears to work fine, but after each restart or boot the problem reoccurs. This has me ruling out hardware problems, but I have also heard that it could be the keyboard controller on the motherboard, so now I am seeking some direction. I would like to end this permanently. Has anyone here experienced this problem? If so, and you have found a solution, would you pass along the information. Much appreciated and Thanx in advance for your kind consideration.
