I decided to replace the thermal compound on my macbook since the warranty has ended recently. When I went to go take the ram out the first stick came out fine, the second one did not. I met the same resistance on the leaver as the first one but it suddenly gave and went all the way back without the stick being pushed out. After I opened it and managed to get the ram out I noticed that the part of the logic board that the leaver pushes against was damaged and a transistor? was broken clear off. So I replaced the thermal compound and put it back together anyways, and well It seems to be working fine. But I was just wondering if anyone knows what I broke off was for and If I might have problems in the future because of it. It's just above the red arrow.
