"Removing the cover and bezel" on page 12). Determine the socket where the
microprocessor is to be installed.
Attention:
v Avoid touching the components and gold-edge connectors on the
microprocessor. Ensure that the microprocessor is completely and correctly
seated in the socket. Incomplete insertion might cause damage to the system
board or to the microprocessor.
v When you handle static-sensitive devices, take precautions to avoid damage
from static electricity. For information about handling these devices, see
"Handling static-sensitive devices" on page 11.
