Removing a Memory Module
Your system supports the following memory configurations:
Your computer has two user-accessible SODIMM sockets, referred to as DIMM A and DIMM B. The socket closest to the system board, DIMM A, always contains
a memory module. The DIMM B socket may contain an additional module for improved system memory performance. If the module in the DIMM A socket must
be replaced and DIMM B is installed, DIMM B must be removed first.
1.
Follow the procedures in
Before Working on Your Computer
.
2.
Lay the computer upside down onto a clean, flat surface.
3.
Remove the bottom of the base assembly (see
Removing the Bottom of the Base Assembly
).
DIMM B
The DIMM B socket may or may not be populated with a memory module, depending on the configuration of your system. When viewing the memory
compartment from the underside of the computer, the DIMM B socket is uppermost and DIMM A is closest to the system board.
Removing the DIMM B Module
1.
To remove the DIMM B module, spread away the retaining clips from the side edges of the memory module and lift the free edge of the module so that it
sits at about a 30-degree angle to the system board.
CAUTION:
Before you begin any of the procedures in this section, follow the safety instructions in the
Dell™
Product Information Guide
.
CAUTION:
To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal
surface, such as a connector on the back of the computer.
NOTICE:
If your computer has only one memory module, install the memory module in the socket labeled "DIMM A".
NOTICE:
If you remove your original memory modules from the computer during a memory upgrade, keep them separate from any new modules that
you may have, even if you purchased the new modules from Dell. If possible,
do not
pair an original memory module with a new memory module.
Otherwise, your computer may not function at optimal performance.
NOTE:
Memory modules purchased from Dell are covered under your computer warranty.
