1 Adding or replacing memory modules
The computer has two memory module compartments. The primary memory module compartment is
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.
WARNING! To reduce the risk of electric shock and damage to the equipment, unplug the
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.

2 Effects of increasing memory
When random access memory (RAM) increases, the operating system increases the hard drive space
reserved for the hibernation file.
If you experience problems with hibernation after increasing memory, verify that the hard drive has
enough free space to accommodate a larger hibernation file.
To display the amount of space required by the hibernation file:
▲Select Start > Control Panel > Performance and Maintenance > Power Options > Hibernate
tab.
To display the amount of memory in the system:
●Select Start > Control Panel > Performance and Maintenance > System > General tab.
–or–
●Press fn + esc.
To display the amount of free space on the hard drive:
1. Select Start > My Computer.
2. Right-click the primary hard drive listing, and then click Properties.
