Remove the left computer cover.See “Removing the Computer Covers” in Chapter 7.2. Remove the support panel.Remove the two screws from the support panel (seeFigure 7-4) and pull the back edge tabs on the panelout of the slots in the chassis.3. Remove the memory module.Hold the module by the corners where the handlesare and carefully pull the module out until the edgeconnectors are free from the system board connector.NOTE: Be careful not to touch components or goldedge connectors on the module.4. Place the memory module component-side uponto an antistatic surface.5. Locate the SIMM sockets into which you willinstall or replace SIMMs.Figure 8-4 shows the location of the SIMM socketson the memory module.6. Install or replace the SIMMs as necessary toreach the desired memory total.Follow the instructions in “Installing SIMMs” or“Removing SIMMs” later in this section, asappropriate.7. Replace the memory module.Hold the module by the corners with the SIMMsockets facing down. Ease the module into the cor-rect slot guides until it is touching the system boardconnector.
