Installing SODIMMs, CAUTION, WARNING,

Page 53 highlights

Installing SODIMMs CAUTION: You must disconnect the power cord before adding or removing memory modules. Regardless of the power-on state, voltage is always supplied to the memory modules as long as the computer is plugged into an active AC outlet. Adding or removing memory modules while voltage is present may cause irreparable damage to the memory modules or system board. The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is important to use memory modules with gold-plated metal contacts to prevent corrosion and/or oxidation resulting from having incompatible metals in contact with each other. Static electricity can damage the electronic components of the computer or optional cards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module. 1. Prepare the computer for disassembly (Preparation for Disassembly on page 30). 2. Remove the access panel (Computer Access Panel on page 38). 3. Locate the memory module sockets on the system board. WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system components to cool before touching. 4. If you are adding a second SODIMM, remove the SODIMM from the top XMM1 socket to access the bottom XMM3 socket. Press outward on the two latches on each side of the SODIMM (1) then pull the SODIMM out of the socket (2). Figure 6-15 Removing a SODIMM Installing Additional Memory 43

the bottom XMM3 socket. Press outward on the two latches on each side of the SODIMM
(1)
then pull the SODIMM out of the socket
