Donegal's four point lead at half time was decisive in Portlaoise yesterday.
Laois suffered a disappointing start to their Ladies National Football League campaign after a home defeat at the hands of Donegal.
Last year's Division Two finalists could only muster 3 points over 60 minutes in challenging conditions.
Donegal, who were 0-7 to 0-3 winners at the final whistle, make their first league game since suffering relegation, a winning one.
Joint manager with the O'Moore County, Tommy Deveraux says he had hoped his players could utilise the wind in the second half better:
Elsewhere in Division Two Westmeath were beaten 2-7 to 1-9 by Tyrone, while Offaly were held to a 1-8 all draw against Sligo in Division Three.
