hi, Mr. Chris oh, i didn't guess that don't have PRAM BATT. My machine only have a capacitor on the logic board. i understood. thank you. i guess main BATT is down too, so doesn't work... Sir mayer, you say not Command+Option+P+R, but Command+Option+O+F. Ok, i will try. thank you so much, every one. shige, tokyo.
