Installing the microprocessor and heat sink
To install the microprocessor and heat sink, complete the following steps:
1. Make sure that the microprocessor socket lever and cover are in the fully open
position.
Attention: Use the vacuum tool provided with the replacement part to install
the microprocessor. Dropping the microprocessor during installation can damage
the contacts. Also, contaminants on the microprocessor contacts, such as oil
from your skin, can cause connection failures between the contacts and the
socket.
2. Install the microprocessor using the vacuum tool and the following procedure
(see Figure 48).
a. Squeeze and hold the bladder of the tool; then, place the suction cup on the
microprocessor and release the bladder.
b. Using the tool, carefully place the microprocessor into the socket.
c. Squeeze the bladder of the tool to release the microprocessor from the
suction cup.
Note: To maintain proper orientation between the microprocessor and the
microprocessor socket during installation, observe the following information (see
Figure 49 on page 116):
v
The microprocessor has two notches that are keyed to two tabs on the sides
of the socket.
v A triangle-shaped indicator on one corner of the microprocessor points to a
45-degree angle on one corner of the socket.
