PCL5100 USER GUIDE
The ZIF socket is designed to accept Pentium® processors (see the
table earlier in this chapter). You may wish to upgrade your
processor by replacing it with one of higher performance.
Read the following instructions carefully before starting work.
1.
Turn off the computer and unplug all power cords.
2.
Take suitable anti-static precautions and remove the system
covers. Take suitable antistatic precautions at all times while
the motherboard is exposed.
3.
Remove any expansion cards that impede access to the
processor.
4.
If the system was in use immediately before starting this
procedure, the processor will be hot; wait at least 15 minutes
for it to cool down.
WARNING
The processor, its fan-sink, if one is fitted, (combined fan and heat
sink), and some of its neighbouring components can get very hot. You
may burn your fingers if you attempt to remove the processor before it
has cooled down.
6.
Unplug the power cable of the processor's fan-sink from the
motherboard. Note where the cable plugs in because you may
need to re-attach it later.
7.
Unclip the fan-sink's retention clip from the ZIF socket at the
front and the back.
8.
Release the lever from the side of the ZIF socket and raise it to
the upright position (at right-angles to the motherboard).
There may be a little stiffness at the beginning and end of the
lever's movement; be careful not to use excessive force.
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.
