CAUTION: Many repairs may only be done by a certified service technician. You should only perform
troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or
telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your
warranty. Read and follow the safety instructions that came with the product.
1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet and
peripherals.
2. Lay the system on its side, on a flat and stable surface.
3. Open the system.
4. Locate the memory-module socket(s).
5. Press the ejectors on the memory module socket down and out to allow the memory module to be inserted into the
socket.
CAUTION: Handle each memory module only by the card edges, making sure not to touch the middle of the
memory module or gold contacts.
6. Align the memory module's edge connector with the alignment key of the memory module socket, and insert the
memory module in the socket.
NOTE: The memory module socket has an alignment key that allows you to install the memory module in the
socket in only one way.
7. Press down on the memory module with your thumbs until the socket levers latch into a locked position.
When the memory module is properly seated in the socket, the levers on the memory module socket align with the
levers on the other sockets that have memory modules installed.
8. Repeat step 5 through step 7 of this procedure to install the remaining memory modules.
9. Close the system.
10. Place the system upright on a flat, stable surface.
11. Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.
12. Press <F2> to enter the System Setup, and check the memory settings.
The system should have already changed the value to reflect the newly installed memory.
13. If the value is incorrect, one or more of the memory modules may not be installed properly. Repeat step 5 through
step 7 of this procedure, checking to ensure that the memory modules are firmly seated in their sockets.
14. Run the appropriate diagnostic test.
