There may be a problem with the power connector port (aka DC-In jack) in the laptop.
Sometimes the inner +ve conductor of the jack can fail intermittently causing no power to be received by the motherboard from the charger.

Follow the procedure and just disconnect the power port cable plug from the card and then connect the charger to the power port. Use a voltmeter to measure the voltage on the red and black wires of the plug. If there is 19.5V DC when measured at the port's cable plug, then ''gently'' move the charger's plug up and down and side to side (not in and out) inside the power port to see if the voltage remains constant or comes and goes.
If it comes and goes or if there's no voltage at all, the jack is faulty and will have to be replaced as it cannot be repaired.
