I am unfamiliar with that particular computer, but this may explain why some switchmode power supplies with universal AC-input voltage {~90-264V, DC~400Hz} have higher inrush with higher line voltage. The supply’s ‘front end’ is a bridge rectifier connected to a DC electrolytic capacitor on one side, and the AC line to the other.
In series with the rectifier’s AC side are low-range inductor(s) to shield it from a small degree of garbage on the AC line—like transient components much faster than 50-60Hz. Another series-connected device that is intended to limit inrush is a thermistor or positive-temperature-coefficient resistor. A marginal-value PTC may be just “on the edge,” and could have originally tested good (not trip) before it left the factory, but the end user’s application slightly different; id est, 115V in factory test is now 230V in the field.
All else being the same, higher AC voltage may lead to higher momentary current. A device like a Fluke 87 with a 1ms peak-reading mode could probably show the inrush-current spike.
