    ASUS K53SV not turning on

    Pardon, but how much voltage should I be getting on AC_BAT_SYS? Is it 5 volts or is it 19 volts? Either way, it's not coming there. lul

        Drain = 19.29 V
        Source = 18.80 V

        That thing next to it, what is it? Where is it located on schematics?
