NSTALLING CENTRAL PROCESSING UNIT (CPU)
Step 1: Pull the lever toward direction A from the socket and then raise the
lever up to a 90-degree angle.
Step 2: Look for the white triangle on socket, and the gold triangle on
CPU should point towards this white triangle. The CPU will fit only
in the correct orientation.
