the blower; reuse the
blower. Your

Removing the Microprocessor
NOTICE: Be careful not to bend any of the pins when you remove the
microprocessor from its socket. Bending the pins can permanently damage the
microprocessor.
Your microprocessor socket is a zero insertion force (ZIF) socket with a
lever-type handle that secures the microprocessor in, or releases it
from, the socket.
1 Pull the release lever straight up until the microprocessor is released,
and then remove the microprocessor from the socket.
2 Leave the release lever extended so that the socket is ready for the new
microprocessor.
