Removing Memory Modules
If you need to remove memory modules from your computer,
follow the steps below. Check the information on page 5-11 to
be sure you remove SIMMs from the correct sockets.
1. It is easiest to remove the SIMMs from the sockets closest to
the processor board first. Then work your way toward the
sockets farthest from them.
Use your fingers or two small screwdrivers to pull away the
metal tabs securing the SIMM at each end. Be careful not to
pull the tabs too far, or they may break.
As you pull away the tabs, the SIMM falls to the right at an
angle. Carefully remove the SIMM.
2. Repeat step 1 for each SIMM you need to remove.
