I consider it possible. More likely, though, the fault is on the
mainboard with the voltage regulator / battery charger circuitry,
In which case you're probably out of luck.

No, I wasn't sure if it was 19 or 20V. In practice it will probably
work with either, and the idle voltage of the power supply is more
likely closer to 20V, even if it's nominally 19V.
