Replacing the Processor Chip

Follow these steps to replace the processor chip:
1. Use the illustration on page 4-5 to locate the microprocessor
on the system board. The microprocessor chip may be
inserted in a ZIF (Zero Insertion Force) socket.
caution
Make sure you ground yourself by touching the metal
surface on the inside of the computer's back panel before
you touch the processor chip. Then remain as stationary
as possible while you install it. Do not touch the pins on
the processor chip. Handle the microprocessor only by
the edges of its case.
2. Open the ZIF socket by lifting up the ZIF handle. The handle
rests under a plastic tab. Press the handle down and away
from the tab; then rotate the handle to the released position.
This releases the chip from the socket. The illustration on
the next page shows this handle in the released position.
If your microprocessor isn't inserted in the ZIF socket with a
handle, use a chip puller or a small, flat-head screwdriver
to remove the chip. Carefully wedge the tip of the
screwdriver between the processor chip and the socket.
Gently turn the screwdriver until the chip begins to
separate from the socket. Move the screwdriver to another
side of the processor chip and again turn it until the chip
separates from the socket. Keep doing this until you can lift
the processor chip straight up from the socket.
3. Gently pull the processor chip straight up and set it aside.
