located under the keyboard. The expansion memory module compartment is located on the bottom of
the computer.
The memory capacity of the computer can be upgraded by adding a memory module to the vacant
expansion memory module slot or by upgrading the existing memory module in the primary memory
module slot.

power cord and remove all batteries before installing a memory module.
CAUTION Electrostatic discharge (ESD) can damage electronic components. Before
beginning any procedure, ensure that you are discharged of static electricity by touching a
grounded metal object.
CAUTION To prevent damage to a memory module, hold the memory module by the edges
only.
