1 Adding or replacing memory modules
The computer has one memory module compartment, which is located on the bottom of the computer.
The memory capacity of the computer can be upgraded by replacing one of the memory modules 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, touch a grounded metal object to be sure that you are discharged of static electricity.
To add or 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.

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 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, and do not bend 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.

2 Increasing hard drive space for the
Hibernation file
When Hibernation is initiated, the operating system stores 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 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 primary hard drive:
1. Select Start >My Computer.
2. Right-click the primary hard drive listing, and then click Properties.
▲To display the amount of hard drive 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:
▲Select Start >Help and Support >Performance and Maintenance >Freeing up disk
space and follow the on-screen instructions.
