Hi, I'm in serious problem with my macbook white 13.3 inch late 2008 running with mac osX 10.5.8. I was using my mac without any problem. Suddenly one day after resrarting, yhe built in keyboard & trackpad stopped working. I continued with external keyboard & mouse. after about 2 months, A message comes after login when the external keyboard or mouse was unplugged: There isn't a mouse/keyboard connected..... then it searches for bluetooth keyboard /mouse. Pls help me. I don't know what to do....
