Prerequisites
CAUTION:
Many repairs may only be done by a certified service technician. You should only perform troubleshooting and

NOTE:
The memory modules are hot to touch for some time after the system has been powered down. Allow the
memory modules to cool before handling them. Handle the memory modules by the card edges and avoid touching the
components or metallic contacts on the memory module.
CAUTION:
To ensure proper system cooling, memory module blanks must be installed in any memory socket that is not
occupied. Remove memory module blanks only if you intend to install memory modules in those sockets.
Steps
1. Locate the appropriate memory module socket.
CAUTION:
Handle each memory module only by the card edges, ensuring not to touch the middle of the memory
module or metallic contacts.
