the Pentium II machines are upgradeable to 288MB maximum.
Caution:
Electro Static Discharge (ESD) can damage electronic components. Before
touching the memory module, ensure that you are discharged of static elec-
tricity by touching a grounded metal object.
INSTALLATION INSTRUCTIONS:
1. Turn the computer off and disconnect the AC power supply and any
other cables from the unit.
Note: If the unit appears to be powered down, ensure that it is not in
Suspend mode.
2. Turn the computer upside-down and rotate it so that you are facing the
front of the system. Remove the battery from the system. If you are not
familiar with this procedure, please refer to your computer’s “Owner’s
Manual.”
3. Locate the memory expan-
sion cover on the right side of
the bottom panel. Also locate
its single holding screw. Use a
small Phillips screwdriver to
remove the holding screw.
Then remove the cover by lift-
ing it to the right.
4. Locate the two memory expansion
slots in the open compartment. Also
notice the location of the off-center
key on each of the expansion slots.
Depending on the model of your
computer, there may be a standard
memory module occupying one of
the slots. If your system has a mod-
ule occupying one of the slots and
you wish to expand your system to
its maximum amount of memory, the
standard memory module will need
to be removed and then replaced
with a higher capacity module. If
you do not need to remove a memo-
ry module at this time, please pro-
ceed to step 6.
5. To remove a memory mod-
ule, locate the retaining clips on
both sides of the memory mod-
ule. Gently pull both clips away
from the module, then lift the
module out of its expansion
slot.
6. To install a memory module,
insert the module into the expan-
sion slot at an angle and then push
it down until it clicks into place.
To be certain that the module is
installed correctly, ensure that the
off-center notch on the module is
aligned with the off-center key of
the expansion slot. The module
can only be installed one way due
to the position of the notch.
Note: For optimum performance, install the largest capacity memo-
ry module into the top expansion slot.
7. Replace the memory expansion cover and be sure to secure its holding
screw.
8. Insert the battery back into its compartment and turn the system right-
side up.
9. Replace the AC power supply and any other cables you may have dis-
connected.
10. Open the display screen and turn the system on. The computer will
automatically reconfigure itself to recognize the additional memory. The
new memory can be verified during the POST routine at start-up and at
the SETUP utility.
The installation is now complete.
