Check the DC-in MOSFETs (usually two N-channel transistors near the power jack). Measure if 19V passes through the second MOSFET to the current-sensing resistor. If the voltage drops to 0V after the first MOSFET, the Super I/O chip or charging IC is likely blocking gate deployment due to a detected short.
