Hello to everyone, I'm a new user. Today I have had an issue come up that needed urgent attention so I am posting this thread. Usually I find what I'm looking for by searching, but I couldn't find anything regarding the problem at hand which is why I'm posting. I have a Macbook Pro Late 2011. I bought the OWC data doubler bundle. It comes with a hard drive, caddy, and tools for the job. When trying to take the screws that held the bracket keeping the airport and blue tooth cables, I managed to strip then. After applying a lot of pressure, I was able to extract the screws. In the process, I unknowingly may have loosened a small part on the logic board. After installing the second hard drive and turning my mac on, I checked disk utility to format the disk. Everything seemed fine so I turned my Mac over to screw the backplate back up. When I turned it over, I heard a clink on the backplate and I thought it was a loose screw even though I made sure the screws were snug. So I took the backplate off and I see a small part of what I assumed to be a transistor, lying there. I say small part instead of transistor because I really don't know what it is. I'm attaching an image of what it looks like. In the image, there is some text saying Power-on Pads. The small part I'm talking about is in between the a and the d of the word "pads". It might be a little unclear, if so, I'll take a picture of the part and post it up. Here is the image: Only the top part had come off. I haven't turned on my mac since I saw that. I'm writing this on my tablet. If anyone knows what this piece is, can you please let me know. And also, would it be okay to solder it back on? What have I done to my machine now that it's off? What steps should I take to fix this? Thank you for reading.
