I recently bought a PS2 and decided to try the magic key. I took apart my PS2 and got everything installed properly and ran into a problem. I bought the system 2nd hand and saw some debris that I blew out of the interior. While doing this I tilted the system. I had a small metal 6/8 by 5/8 of an inch fall out. There is a small hole in the center which one of the screws can fit thru. I believe it came out from under the fan. I was hoping someone had taken their slim PS2 entirely apart and could tell me what this piece is and how important it is. Thank you for any help.
