1 Replacing the memory module
The computer has one memory module compartment, which is located on the bottom of the computer.
The memory capacity of the computer can be enhanced by upgrading the existing memory module in
the 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.
To replace a memory module:
1. Save your work.
2. Shut down the computer and close the display.
If you are not sure whether the computer is off or in hibernation, turn the computer on by pressing
the power button. Then shut down the computer through the operating system.
3. Disconnect all external devices connected to the computer.
4. Unplug the power cord from the AC outlet.
5. Turn the computer upside down on a flat surface.
6. Remove the battery from the computer.
7. Loosen the memory module compartment cover screws (1).

8. Lift the memory module compartment cover (2) away from the computer.
9. Remove the memory module:
a. Pull away the retention clips (1) on each side of the memory module.
The memory module tilts up.
CAUTION To prevent damage to the memory module, hold the memory module by
the edges only. Do not touch the components on the memory module.
b. Grasp the edge of the memory module (2), and gently pull the module out of the memory
module slot.
To protect a memory module after removal, place it in an electrostatic-safe container.

10. Insert a new memory module:
a. Align the notched edge (1) of the memory module with the tab in the memory module slot.
CAUTION To prevent damage to the memory module, hold the memory module by
the edges only. Do not touch the components on the memory module.
b. With the memory module at a 45-degree angle from the surface of the memory module
compartment, press the module (2) into the memory module slot until it is seated.
c. Gently press the memory module (3) down, applying pressure to both the left and right edges
of the memory module, until the retention clips snap into place.
CAUTION To prevent damage to the memory module, do not bend the memory
module.
11. Align the tabs (1) on the memory module compartment cover with the notches on the computer.

2 Effect of increasing memory on the
hibernation file
When hibernation is initiated, the operating system saves your information to a hibernation file on the
hard drive and then turns off the computer. The operating system reserves space on the hard drive to
store the hibernation file based on the amount of system memory. When you increase the system
memory, the operating system increases the hard drive space reserved for the hibernation file.
If you experience problems with hibernation after increasing memory, be sure that the amount of free
space on the hard drive is larger than the space required by the hibernation file.
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.
To display the amount of space required by the hibernation file:
▲Select Start > Control Panel > Performance and Maintenance > Power Options > Hibernate
tab.
If the free space on the hard drive is less than the space required by the hibernation file, increase the
amount of free space on the hard drive. For assistance, select Start > Help and Support >
Performance and Maintenance > Freeing up hard drive space.
