10 Maintenance

Adding or replacing memory modules

The computer has one memory module compartment. The 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.

NOTE: Before adding or replacing a memory module, make sure the computer has the most recent

BIOS version, and update the BIOS if needed. See

Updating the BIOS on page 76.

CAUTION: Failure to update the computer to the latest BIOS prior to installing or replacing a

memory module may result in various system problems.

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 information loss or an unresponsive system:

Shut down the computer before adding or replacing memory modules. Do not remove a memory

module while the computer is on, in the Sleep state, or in Hibernation.

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.

NOTE: To use a dual-channel configuration when adding a second memory module, be sure that

both memory modules are identical.

NOTE: The primary memory is located in the bottom memory slot and the expansion memory is

located in the top memory slot.

To add or replace a memory module:

1. Save your work and shut down the computer.

2. Disconnect AC power and external devices connected to the computer.

3. Remove the battery (see

Removing a battery on page 41).

4. Remove the hard drive cover (see

Removing the hard drive cover on page 51).

5. To remove the memory module compartment door:

a. Turn the computer upside down on a flat surface, with the memory module compartment

door toward you.

b. Loosen the 5 screws (1).
