While the Cummins Onan 5500 watt generator technically produces a sine wave, the waveform can be very "dirty", depending on load. Some power supplies have a problem with this, although I've rarely seen a situation where the laptop ran, but didn't charge. In any case, either adding a small pure sine wave inverter, or purchasing a 12V supply for the laptop would likely solve your problem.
