Note – System cooling might be affected by dust and contaminant build-up.
Therefore, you should open and check systems approximately every six months (or
more often in dirty operating environments). Check system heatsinks, fans, and air
openings. If necessary, clean systems by carefully brushing, blowing, or vacuuming
contaminants from the system.
10. Align the CPU to the socket.
a. Gently insert the CPU pins into the socket.
Caution – The pins on the CPU are very fragile. If the CPU is correctly aligned, it
will enter the CPU socket with little or no resistance. If you feel more than minimal
resistance, stop and recheck the alignment. Forcing a misaligned CPU into the CPU
socket could damage both devices.
Tip – Align the gold triangle on the CPU with the white triangle on the socket. Also
note the location of the keys (notches) on the CPU.
11. When the CPU is fully seated in the socket, pivot the release lever down until it
is locked into position, at the side of the socket.
Caution – The pins on the CPU are very fragile. If the CPU is correctly aligned, it
will enter the CPU socket with little or no resistance. If you feel more than minimal
