Trackpad not flush with the keyboard surface
The Trackpad of my MacBook 13" Late 2009 Model A1342 was slightly up in the left side, so I decided to open it to check what was happening inside, following the instructions in your site. When I took out the battery pack I figured out that it is seated over the battery body. Then I could do nothing, because when I replaced the battery the trackpad still remained slightly up. Is there a way to fix this? The only explanation for this is that the battery is slightly up, or, I don't know... it has grown slightly in volume?!?
Some idea how to fix it?
Another question is that, when I was doing this procedure I found two black Phillips screws loose inside the MacBook, and I cannot figure out from where they are, because it's the first time this MacBook is opened, and all the screws I took out in this procedure are back in their places, and those two loosened screws are about 9mm to 10mm high.
The screws are 9mm to 10mm high, and not 100mm.
