B. Follow the steps below to correctly install the CPU into the motherboard CPU socket.
Before installing the CPU, make sure to turn off the computer and unplug the power cord from
the power outlet to prevent damage to the CPU.
Step 1:
Gently press the CPU socket lever handle down
completely lift the CPU socket lever and the metal
load plate will be lifted as well.
Step 3:
Align the CPU pin one marking (triangle) with the
pin one corner of the CPU socket (or you may align
the CPU notches with the socket alignment keys)
and gently insert the CPU into position.
Step 5:
Push the CPU socket lever back into its locked
position.
Step 2:
Remove the CPU socket cover as shown. Hold
socket cover and use your thumb to lift up the
front edge (next to the "REMOVE" mark) and
then remove the cover. (DO NOT touch socket
contacts. To protect the CPU socket, always
replace the protective socket cover when the CPU
is not installed.)
Step 4:
Once the CPU is properly inserted, use one hand
to hold the socket lever and use the other to lightly
replace the load plate. When replacing the load
plate, make sure the front end of the load plate is
under the shoulder screw.
NOTE:
Hold the CPU socket lever by the handle, not the
lever base portion.
