I decided to take the HD out of my Acer 5672 for one reason or another and discovered the hard way that it sits on a little foam pad which site on a flat cable which hooks the 2 side USB2 ports to the motherboard. Needless to say, lifting out the HD pulled the cable from the Motherboard.

Long story short, I've checked the Acer site for a manual for this laptop but I can't find one as they don't seem to have the model listed. Any idea where I might find one?

Phone or email Acer. Also look online for disassembly photos.

I'm guessing you pulled a ribbon cable out. Man, I hate those. Be gentile with that cable since there aren't standard replacements easily available.
