CHICAGO -- Blackhawks coach Denis Savard just wants his team to continue playing the way it's been playing.
Chicago, with 60 points, is six points behind eighth-place Vancouver -- and the final playoff spot -- in the Western Conference.
"Hopefully we'll continue to play that way all down the stretch," Savard said. "We're jelling. Whether we get in (the playoffs) or not, we're going to pay the price every night."
Several injured Chicago players, including rookie forward Jonathan Toews, have come back to help spark the Blackhawks, who have missed the playoffs in eight of the past nine seasons.
"It's our hard work and dedication," Lalime said. "We're battling right now. A lot of it is buying into the system; finally we're playing as a team."
Jose Theodore made 25 saves for Colorado, which lost its third straight and failed to convert any of its six power plays.
The Avalanche have 65 points and are in ninth place in the conference.
"Today was not good," Colorado coach Joel Quenneville said. "I didn't like how we played. We were on the receiving end all night.
"We were in our end a lot. We didn't handle the puck a lot. We made some direct passes from our stick to their stick. We haven't had many games like this."
Byfuglien put Chicago in front during a power play at 4:48 of the first period.
Following a video review, he was credited with deflecting in Wisniewski's shot from the blue line. Originally, the goal had been awarded to Wisniewski.
"We've moved the puck on the power play, but hadn't gotten any goals," Wisniewski said. "It was nice on the first power play to get a 1-0 lead."
Havlat made it 2-0 at 2:53 of the second, shortly after the Blackhawks had killed off a 5-on-3 Colorado power play.
Havlat beat Theodore high on the stick side from the right circle with a rebound of Wisniewski's shot from the point.
Hlinka scored from just outside the crease in the third period. He converted a centering pass from Cody McLeod.
