Try with another, known good charger. Also check +5V_ALWP , and +3.3V_ALWP -

Re: Why laptop vs voltage is missing and solution please
Check voltage on pin4(gate) of fets connected on vs lines. If gates are not opening you wont have vs voltage on the other side of mosfets. You need to check IC's connected with vs side of mosfet(mostly 3pin or 6 pin ic's). You can try by removing the mosfet and check gate voltage of fets. Sometimes the fet itself is defective though it will show normal rating while measured in diode mode.Comment
