Hello, I recently used your guide to take out and replace the hard drive of my laptop. When re-assembling it, I came back to step 29 and got all of the screws back in, except for the lowest of the three all the way to the right, looking down. They are the 2mm phillips screws, circled in red on that step. I unscrewed the others and popped off the plate to find a small rectangular magnet with one side having a sticky residue on it causing the block, having been wedged between the metal inner plate and the base. Now that I removed it, the screw should take, but before I screw it in, I want to know where this piece goes in the machine, as I imagine it was a part of it, and not something that randomly fell into it, as I was working. Thank you, in advance, for your help. -Zach Woliner
I believe the magnet you are referring to is the sleep magnet. If you remove the upper case and are looking at the underside of it, it is adhered in a little niche on the left side of the case, below the keyboard hole.
