Danny Hattersley and Craig Hobson returned to the starting line up for the visit of West Bromwich Albion, who featured a mix of reserve and 'development' players.
The baggies also feature new signing Yassine el Ghanassy, a Belgian international who has recently signed from Genk on a year's loan.
It was the left sided striker that had the first shot of the game in the opening minute and two minutes later saw his break into the box halted by Andy Halls.
The Hatters first effort came on six minutes from a Sean Newton free kick which saw Hattersley head over under pressure from Donovan Daniels.
Good work from Kemar Roofe and Saido Berahino on nine minutes gave el Ghanassy a chance to fire in a cross which Ormson dealt with at his near post.
The visitors were playing some crisp attacking football and George Thorne, who has played in the Premier League for Albion's first team, saw an effort shave the post from a neat pass by el Ghanassy on sixteen minutes.
A minute later and Ormson made the save of the half as he dived full length to keep out a shot from Berahino after a quick free kick by Sam Mantom.
Luke Daniels in the Albion goal was equally impressive on twenty two minutes as he made a full stretch save to tip Hobson's left foot drive over the bar, as County began to find a way into the game.
Three minutes later and the visitors broke the deadlock. Mantom pushing forward from the centre of the park found time to look up and find the corner of Ormson's goal from around 25 yards.
Hattersley then saw his diving header, from another Newton cross, deflected for a corner, before the baggies made it 0-2 just after the half hour mark.
Scott Allan drove down the left hand side and dispatched a superb cut back to Berahino who fired home from the edge of the six yard box to double the lead.
Both sides had further chances before the break, Sheridan firing wide for County on thirty five minutes and Ghanassy hitting the post with a 30 yard effort.

The Hatters opened the second half a good spell of pressure, keeping the ball well and looking comfortable going forward. Tom Collins and Hobson creating chances without troubling Luke Daniels.
Hattersley came close with a header at the far post after good work between Sam Sheridan and Newton had seen the full back put over a decent cross.
On 67 minutes the goal that the Hatters pressure deserved finally arrived and once again it was Danny O'Donnell that delivered.
A quick free kick from Newton, after Hobson had been pole axed by Donovan Daniels, found Alex Kenyon on the left. The midfielder took one touch and sent over a superb cross to the far post where O'Donnell fired home his second goal in as many games to make it 1-2.
Hobson sent a header just over the bar from a right wing cross by Halls as County looked for the leveller.
Unfortunately the visitors struck back against the run of play a Thorne picked up a loose ball in the middle of the park and strode forward before picking out Berahino with a slide rule pass. The striker finished well for his second of the night to make it 1-3.
Thorne then put the game beyond County with the goal of the night. Again picking up the ball in the middle of the park he danced around a couple of challenges before smashing home a shot from the edge of the box to complete the scoring.
