Memory Installation Procedures
To install DIMMs, first make sure the two handles of the DIMM socket are in the
"open" position, i.e., the handles lean outward. Slowly slide the DIMM module along
the plastic guides on both ends of the socket. Then firmly but gently (avoid pushing
down too hard) press the DIMM module well down into the socket, until you hear a
click when the two handles have automatically locked the memory module into the
correct position of the DIMM socket. To remove the memory module, just push both
handles outward, and the memory module will be ejected by the mechanism.
