Laptop will not sleep when lid closed

So I'll start off by admitting that I was an idiot. I removed my logic board to clean it and apply a better thermal paste to the processors, and in the process, I rushed through pulling the board out and broke the tiny little ribbon that connects to the battery status indicator. I put everything back together, and now the indicator will not work (not a big deal), but the more annoying problem is that when I shut the lid of the laptop, it does not recognize the closed lid, and thus will not sleep after shutting the lid. My question is, does anyone know if this ribbon that I broke also controls the magnets that know when I shut my lid, and if not, what should I do to restore this functionality?
