HP/Compaq :: Dv4000 Optical Drive

I have a dv4000. It's a bit dated at 3.5 years I've had it, but a pretty solid and reliable notebook. Never any big problems other than a small crack from handling it wrong. But I recently have had an optical drive problem the past couple of months. It doesn't usually bother me too much until I try to use it with a disc. I bought a Macbook and plan on selling this notebook soon, and want to see if I can fix the problem before I sell it, or at least come to the root.

I can hit it around the optical drive area and sometimes the drive will randomly come open. I didn't accidentally hit the button or anything. That or the light on it will start blinking for a bit. When I hit the button for it to open it takes like 10 tries or so of repeatedly hitting it before it will decide to open. When I get a disc in it sometimes it will blink for a bit and act as if there's no disc. I can open and close it again and it will sometimes recognize a disc and play it, but if I hit the area by the drive too hard it will quit running. I have tried reseating the drive. It seemed to work at first, but then it started up with the same problems. My best guess is that it coming disconnected with the data connectors or something and causing it to act up, but I wouldn't know how to keep it any more connected with only 1 screw holding it in...
