    trước khi có run_on phải có slp_s3,S5 từ chip nam gởi về IO. Trước khi có SLP_s3,s5 phải có rsm_rst, pwrBTN từ IO sang Nam. mạch RTC

    Nếu tỏng trở run_on bình thường ( đo khi máy đã kích nguồn) thì nhấc chân ic , gác lệnh sus_on qua xem sao. Khả năng hở hoặc lỗi chíp nam cao , khò chíp nam xem sao .
