I have two NEC 440Ts. They are great workhorses. However, as you have
noticed, the memory does need to be upgraded, 96MB ain't much these
days.

Memory in an NEC 440T laptop is located under the keyboard.

To access the memory, you must "pop" up the LED & power
switch panel. This is done by bending the display back parallel with
the unit. The panel may be popped up by popping up the two hinge
covers on the back of the panel. Please be very, very careful. It is
very easy to damage the connecting circuitry. Damaging the circuitry
is a common problem, and parts for an NEC 440T are not easy to find.

I may be easier to bend the display back only about 10 degrees less
than parallel. Then, when the panel is loose, the display may be
moved completely parallel. Using this method may be less risk for
damage, since the display will only allow the panel to be popped up
so far.

Do NOT remove the panel completely. Only loosen it to the point that
it is detached. This is required to remove the keyboard. Then, the
keyboard can be laid back to give access to the memory compartment.
The keyboard is attached on the slide pad side of the keyboard (the
side closest to the operator).

There is also a piece of sheet metal that covers the memory
compartment, but is under the keyboard. The sheet metal also needs to
be removed to gain access to the memory.

Once all the above is loosened or removed, the memory may be seen
and/or removed, replaced or upgraded.

It is also wise to replace the memory sticks with the exact type.

It is also a good idea to replace the module closest to the battery,
first.

To the best of my memory, the NEC Ready 440T uses: 144 Pin PC66 CL3
SDRAM SODIMM sticks.

I hope this helps.

Just a note: Many parts are inter-changable with a Micron Trek2.
However, I understand that the memory is not exactly the same.
