Opening and Examining the CPU Socket
First, raise the CPU socket lock lever on the mainboard, as shown in Figure 25, until the lever is fully opened. For the Athlon Socket A, this means lifting the lever so it points straight up into the air (Figure 26). A small notch locks the lever into place when its closed, so youll need to pull the lever very gently away from the socket to clear the closing notch when you first lift it.
Examine the pin holes of the socket (socket pins). Youll see that the pattern of the holes will only allow insertion of a CPU in one orientation.
For the Athlon, youll see that two of the corners have pin socket holes that end in a triangular formation, i.e., they dont use the pins at the very corners. Thus, if you have the orientation of the CPU incorrect, a corner pin of the CPU wont have a hole to go into, and the CPU wont seat into the socket. This is designed to prevent people from inserting the CPU incorrectly and damaging the CPU. Rest assured, its nearly impossible to insert a CPU incorrectly.
The Athlon also has a small triangle on the top of the chip to indicate its proper orientation.
