and set it on the bag or the antistatic mat, if you have one.

Install the processor. First, find pin 1 on the processor; it usually is denoted by a corner of the
chip that is marked by a dot or bevel. Next, remove the cover from the processor socket (if so
equipped—see
Figures 19.4
and
19.5
) and find the corresponding pin 1 (or land 1) of the socket
for the CPU on the motherboard (see
Figures 19.5
and
19.6
); it also is usually marked on the
board or with a bevel in one corner of the socket. Be sure the pins on the processor or socket
are straight and not bent; if they are bent, the chip won't insert properly into the socket. If
necessary, use small needle-nose pliers or a hemostat to carefully straighten any pins. Don't
bend them too much—they might break off, ruining the chip or the motherboard. Insert the CPU
into the socket by lifting the release lever until it is vertical. Then align the pins or lands on the
processor with the holes or pins in the socket and drop it down into place. If the processor does
not seem to want to drop in all the way, remove it to check for proper alignment and any bent
pins. When the processor is fully seated in the socket, push down the locking lever on the socket
until it latches to secure the processor (see
Figures 19.7
and
19.8
).
