2.3 Installing Internal Notebook Options

If you have no internal options to install at this time, skip to Paragraph 2.4. Otherwise,
continue with Paragraph 2.3.1.

2.3.1 Installing Main Memory Expansion (Optional)

Main memory on the 900 Series Notebooks can be expanded using an EDO Small
Outline Dual Inline Memory Module (EDO soDIMM). These modules are available in
8 MB, 16 MB, 32 MB, and 64 MB sizes and install in the expansion memory slot on
the System Board accessed through the Memory Expansion Door on the bottom of the
notebook. The installation process consists of the following steps:
Caution: The EDO soDIMM module option contains components that are
sensitive to static electricity. When handling the module and the internal
parts of the computer, protect against static electricity by using wrist or
ankle grounding straps and grounded working mats. When moving or
storing items, use the anti-static bags supplied with the items.
1. Ensure that the notebook is powered off and the AC adapter disconnected
from the AC outlet. Also, ensure that all batteries are out of the unit.
2. Disconnect any peripheral device interface cables from the external interface
connectors and remove any installed PCMCIA options.
3. Turn the notebook over and locate the Expansion Memory Access Cover on
the bottom of the notebook.
4. Remove the screw holding the Expansion Memory Access Cover and remove
the cover.
5. Remove the EDO soDIMM module from its shipping container.
6.
Refer to Figure 2-1. To install an soDIMM module, first align the connector
edge of the memory module with the key in the connector. Insert the edge of
the memory module board into the connector using a rocking motion to fully
insert the module. Push downward on each side of the memory module until
it snaps in place.
7. Reinstall the Expansion Memory Access Cover using the screw removed in
Step 4.
8. Replace the batteries and AC adapter.
9.
Power up the notebook. If all of the installed memory is not recognized, try
reseating the soDIMM module and rebooting.
