Working on a customers pc keyboard backlight issues. The backlight isn't working, and the sony control center doesn't have the option to enable the feature. He claims it worked in the past. I tried the download for the new control center, still no luck. Tried installing the sony shared library, it says it cant install on this os, and yes I made sure it was the right os. I reinsearted the cables to the mobo but nothing. any idea guys??????
