Performing a Memory Upgrade
CAUTION: Before you perform this procedure, see "Safety
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information Guide.
1.Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2.Remove the cover (see "Removing the Cover" in "Troubleshooting Your System").
3.Lay the system on its right side.
4.Install or remove memory modules as necessary to reach the desired memory total (see "Installing Memory Modules" and "Removing Memory Modules").
See Figure
5.Stand the system upright.
6.Install the cover (see "Installing the Cover" in "Troubleshooting Your System").
7.Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.
After the system completes the POST routine, it runs a memory test.
