Removing and installing memory modules
Make sure you read Precautions and procedures before you remove or install a memory module. When installing a memory

Electrostatic discharge (ESD).

The interior of the computer becomes extremely hot during operation. Wait at least one hour for the computer to
cool down before you remove the screws.
