Replacing a SODIMM CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power to drain before removing or installing a memory module. Regardless of the power-on state, voltage is always supplied to the memory module as long as the computer is plugged into an active AC outlet. Removing or installing a memory module while voltage is present may cause irreparable damage to the memory module or system board. The memory module socket has gold-plated metal contacts. When upgrading the memory, it is important to use a memory module 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 15). 2. Remove the access panel (Access Panel on page 16). 3. To remove a SODIMM, press outward on the two latches on each side of the SODIMM (1) then pull the SODIMM out of the socket (2). The computer automatically recognizes the additional memory when you turn on the computer. NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket. Memory 21
