HINT: This procedure
covers removing and
replacing the memory
module located under the
memory module/modem
cover on the bottom of the
computer. A second
memory module resides
on the upper surface of
the system board under
the EMI shield. To replace
the memory module under
the EMI shield, perform
the procedure for
removing the EMI shield.
Then replace the memory
module.
Turn the computer over, and remove the memory module/modem
cover:
Remove the M2.5 x 5-mm screw from the memory
module/modem cover.
Slide the cover out approximately 10 mm, and lift it away from the
computer.

NOTICE: To prevent damage to the memory module connector, do not use
tools to spread the inner metal tabs that secure the memory module.
If you are replacing a memory module, remove the existing module.
NOTICE: Handle memory modules by their edges, and do not touch the
components on a module.
Use your fingertips to carefully spread apart the securing clips on
each end of the memory module connector.
The module should pop up.

connector.
Slide the edge of the module firmly into the connector, and rotate
the module down until you hear a click. If you do not hear the
click, remove the module and reinstall it.
Replace the cover and screw:
Place the memory module/modem cover over the memory
module/modem compartment so that the end of the cover with
the screw hole is lined up with the lines and arrows on the bottom
of the computer.
Press down on the center of the memory module/modem cover,
and slide the cover until it is secured.
Replace and tighten the M2.5 x 5-mm screw.
NOTICE: If the memory module/modem cover is difficult to close, remove the
module and reinstall it. Forcing the cover to close may damage your computer.

Insert the battery into the battery bay, or connect the AC adapter to
your computer and an electrical outlet.
Turn on the computer.
As the computer boots, it detects the additional memory and automatically updates the system configuration information.
CAUTION: Before performing these procedures, turn off the computer, disconnect it from the electrical outlet, and disconnect the modem from the telephone wall jack.
NOTICE: Disconnect any attached devices from electrical outlets, and remove
any installed battery.
NOTICE: To avoid ESD, ground yourself by using a wrist grounding strap or
by touching an unpainted metal surface on the computer.
Turn the computer over, and remove the memory module/modem
cover:

Disconnect the flex cable from the ZIF connector:
Pull the securing tab away from the ZIF connector.
Gently pull the flex cable out of the ZIF connector.
HINT: If you do not
connect the flex cable to
the ZIF connector
properly, your floppy drive
will not function properly.
Reconnect the flex cable to the ZIF connector:
Pull and hold the securing tab away from the ZIF connector.
While holding the securing tab, insert the flex cable into the ZIF
connector.
Ensure that you insert the flex cable into the ZIF connector and not below the ZIF connector.
