OWNERS HANDBOOK 5/11
9. Lift the processor (with fan-sink) clear of the system unit and
place it on an anti-static surface. Hold the processor by its
edges and avoid touching any of the metal pins.
10. Separate the fan-sink from the processor by twisting the fan-
sink from side to side to loosen the grip of the thermal
bonding compound, then slide the fan-sink off to one side of
the processor.
WARNING
When you remove the fan-sink there will be a residual deposit of
thermal bonding compound on the bottom of the fan-sink and the top of
the processor. This compound can cause skin irritation and stain
clothing. Avoid prolonged or repeated contact with skin. Wash your
hands thoroughly with soap and water after handling. Avoid contact
with eyes and inhalation of fumes. Do not ingest.
11. If you are replacing a Pentium processor with a
Pentium/MMX processor, you
must
remove the two jumpers
from jumper block
PL18
(next to the socket). Use the
illustration at the start of this chapter to locate this jumper
block.
12. Ensure that the securing lever on the ZIF socket is still in the
upright position.
13. Take the upgrade processor out of its anti-static packaging.
Hold the processor by its edges and avoid touching the metal
pins.
◊
The upgrade processor and the ZIF socket are keyed to
ensure that the processor is installed in the correct
orientation. (The pin pattern is totally different at one
corner.) It will only fit into the socket one way.
14. Place the processor in the socket, making sure that it is
correctly aligned and that you do not bend or otherwise
damage the pins.
◊
If the processor is not big enough to occupy the entire
socket it should be positioned centrally.
