I dropped a rather large crumb of sugar inside my notebook via the hinge and I decided than rather let the crumb cook and cause damage, I though I'd go in and fish for it myself. I wound up breaking something, causing a bigger problem. The scary part is that I don't know what I broke. Right next to the HDD there is a large black plastic part that separates it from the Super Drive. It's got a wire under it that ripped off rather easily. What is it ?
