SERVICE PROCEDURES 77
Replacing parts on the motherboard
This section describes how to remove and replace the DIMMs, CPU, and battery on the
motherboard. Before you perform any of these procedures, shut down and open the E-41 (see
page 49).
DIMMs
The motherboard has four DIMM sockets. The E-41 standard memory configuration
populates two sockets, each containing a 1GB DIMM, for a total of 2GB of memory.
NOTE: When installing DIMMs, note the following:
• Different capacity DIMMs look alike. Make sure that you know the capacity of each
DIMM before you install it in a socket.
• Install only approved DIMMs available from your service representative.
• DIMMs must be installed in matched pairs. A matched pair is comprised of two alternate
sockets (see below). DIMMs within a pair must be identical (same capacity and same
number of chips on each side). For example, in a two-DIMM configuration, populate
DIMM 4 and DIMM 2 with DIMMs of identical capacity, with the same number of
chips on each side.
