gently. Do not over-tighten them.
Find the connector labelled PL12 on the left of the main computer circuit board.
Plug the wires coming from the fan onto this connector. They will only fit correctly
one way round.
Fitting the LED
The LED provided replaces the existing power LED on the front plastic fascia
assembly of the computer. You will probably need to remove this assembly to fit it.
To free the fascia assembly you must remove five screws. There are three
underneath the front of the computer and one on each side near the front. The last
t
wo are hidden when the top cover is in place. The screws underneath are best
removed by resting the computer on its side before the top cover is removed.
After removing the five screws, ease the fascia assembly forward. Do this very
gently because there are wires attached to it. Notice where these wires are
plugged onto the main circuit board just in case they come adrift.
The LED is attached to the fascia with a small amount of glue, but you should be
able to ease it out. Coil up the LED with its wire and tie it out of the way using one
of the cable ties provided.
Fit the new LED to the same slot in the fascia and use the small piece of tack
supplied to hold it in place. Route the cable through the front of the computer
alongside the power supply.
I
f you have difficulty replacing the LED the fascia can be further disassembled by
undoing the screws visible inside it.
Replacing the fascia assembly can be a little fiddly. Be patient and do not force it.
Put a spare floppy disc in the floppy drive without pushing it right in: this will help
to guide the fascia into position. The floppy drive eject button sometimes falls off
and you may wish to fix it on with a drop of superglue.
As you push the fascia home, check that you do not trap any wires. Have a look at
the front edge of the circuit board near the bottom of the computer: this should
engage in plastic slots in the fascia panel. When the fascia is in place check that
the floppy drive eject button works.
Replace the five fascia assembly screws.
(
After completing the installation you might very occasionally find that the floppy
drive does not work properly because the fascia assembly is not quite in the right
position, even though it may look correct. Remove the fascia and try again.)
