That pretty well sums it up> I know the basics of cracking the case, but I
don't know where the chip is located exactly. Any advice/instruction is
appreciated.
Thanks,

March

I assume that you mean you want to remove a memory expansion card. (Now
THAT is an oddity -- someone who needs LESS memory in their machine!)

The following procedure was arrived at empirically when I installed
a memory expansion card in my 520c. I presume it'll work for removal
as well :-).

1. Remove the two screws on either side of the serial number plate
under the back cover.

2. Remove the two screws beneath the keyboard. The keyboard will pop up
and you can remove it by pulling toward the front of the machine. It
has a reasonably long cable, but don't pull too hard on it.

3. Remove the plastic shield covering the very back of the computer. This
is immediately below the display, extending between the hinges. It
will snap out more or less reluctantly.

4. Remove the two screws on top of the card cage and the one at the back.
You can now remove the card cage cover.

5. Remove the plastic hold-down strip by flexing it slightly. The
card being held down is the memory card.

6. Remove the memory card by pulling straight up. Verify that you
haven't bent any pins on the connector after the card is removed.

7. Replace the plastic hold-down strip.

8. Replace the card cage cover and its three screws.

9. Replace the plastic shield at the back of the machine. This will take
some careful maneuvering.

10. Replace the screws in the back of the computer on either side of
the serial number plate. These secure the plastic shield.

11. Replace the keyboard and secure with the two screws at the bottom
of the machine.

You'll need one tool, a Torx-8 screwdriver. You must have a screwdriver,
not a bit and handle, because there is inadequate clearance in the recessed
screw holes at the bottom of the computer to pass the shaft of the
interchangeable-bit driver.

Again, this procedure was derived empirically; it's NOT from any
official publication.

Good luck!

Remove the two screws from the back. Two in the middle from under it.
remove keyboard (it is now unscrewed). Remove the thin strip of plastic
right under the screen hinge swivel thingy. There are three screws you
need to take out from a metal cover over the RAM/Motherboard.
Unfortunately I think there are four screws there. Remove the two on
either side of the metal cover about midway front to back. lso remove the
one about three quarters to the right and deepest down under the screen.
(Thus the need to have removed the plastic thing back there)

Now, you should be looking at the big 68LC040 on the screen side, and the
RAM card on the side closer to you. Remove the grey plastic strip from
over the RAM card. (This can be tricky, slide it out toward the screen)

Now, you are ready to remove the RAM card. I did this once. It scared the
daylights out of me. It can be really tight. Just pull up evenly and
firmly, and hope it doesn't go flying across the room when it finally
comes out.

When you put new RAM in, be sure to fit it into the two slots toward the
trackpad before pressing it down into the slot.

Good Luck,
Jeffrey
