King's Lynn maintained their 100 per cent home record by stretching their unbeaten run to seven matches with a 2-0 victory over Darlington.
Chris Henderson was on target with a brace at the Walks after stepping into the boots of injured striker Adam Marriott.
Ian Culverhouse's side created very little in the way of clear-cut opportunities in a scrappy first half display.
Darlington centre-backs Josh Heaton and Laing both came close to scoring with headers at first-half corners, while Will Hatfield saw a volley saved.
After the break it was a different story as the Linnets took full control of the game.
Henderson gave Lynn the lead after 51 minutes, making the most of hesitation in the visiting defence when latching on to a through-ball from Alfie Payne and executing a cool finish from inside the penalty area.
It was 2-0 just before the hour-mark and again it was Henderson who caught the Quakers flat-footed before dribbling away from the defence and passing the ball into the bottom corner after being played in by Michael Gash.
There was still time for Heaton to hit the Linnets' woodwork with an audacious 60-yard lob while Gash struck the base of the post at the other end.
