Gateway laptop speakers aren't working

[gcounts]

I own a Gateway MX6440 laptop that was dropped and broke the LCD. I replaced it and it's working great except that the internal speakers aren't working. I know the audio driver is working fine because I can use USB external speakers or headphones and the sound is great. Does anyone know where the speaker connector is on these? I find it hard to believe the MB is damaged because everything else is working great! Is there a connector that could have become unplugged with the drop? Thanks.

Also, is there a place that has a diagram showing how to remove the laptop case to get to the MB?

most laptops you have to remove the keyboard to get to the mb and the audio jack is the one that has a little picture of headpones.
