+1.2V_VDDQ ---[R1110]--- VREF_DDR (Pin 7 of U300) | GND The 1.2V main memory rail passes through a 0-ohm resistor (R1110) to create a reference voltage for the memory slot. If R1110 is missing or cracked, you get no memory voltage, leading to "No POST." This board, manufactured by Compal (the OEM behind
