Screw Schematic / Physical part listing - acer aspire 515-51

Falwaeth

I bought an acer aspire 515-51 laptop four or five years ago from a wal-mart. I don't remember it coming with a manual, I think i had purchased the floor model. I took it apart a few months ago because certain keys stopped working, and I thought I could solve the problem. I thought incorrectly. I was in a bit of a hurry on the reassembly, and just snapped the back panel back on without putting any of the screws back in. Got a bluetooth keyboard to resolve that situation.

Today I put everything back together. The 15 back panel screws were installed, but i have two left over. Both have the same thread as the back panel screws. One is about twice the length of the back panel screw, with a blue dot on the threads.The other is half the length of a back panel screw, with a blue dot on the threads. They both have the same head as the back panel screws. Is there a screw schematic for this laptop that anyone could share with me? Or a physical part manual with detailed information?

With no way to edit this post, I want to make a few corrections. Only making the purchase two years ago (life took some pretty drastic turns, felt like a lot longer). The small screw looks similar to an m-2 in length.
