For details on handling these devices, see "Handling electrostatic discharge-sensitive devices" on page 134. 1. Review the safety precautions listed in the "Safety information" on page 131. 2. Turn off the computer and all attached devices. Disconnect all external cables and power cords; then remove the cover. See "Removing the cover" on page 45 for details. 3. Lift the frame support bracket. See "Removing the frame support bracket" on page 46. 4. Touch the static-protective package containing the DIMM to any unpainted metal surface on the computer. Then remove the new DIMM from the package. 5. Gently open the retaining clip on each end of the DIMM slot. Turn the DIMM so that the pins align correctly with the connector. 6. Insert the DIMM into the connector. Firmly press the DIMM straight down into the connector by applying pressure on both ends of the DIMM simultaneously. The retaining clips snap into the locked position when the DIMM is firmly seated in the connector. DIMM connector 1 DIMM connector 2 7. If a gap exists between the DIMM and the retaining clips, the DIMM has not been correctly installed. Open the retaining clips, remove the DIMM, then reinsert it. 8.

package.
5.
Gently open the retaining clip on each end of the DIMM slot. Turn the DIMM
so that the pins align correctly with the connector.
6.
Insert the DIMM into the connector. Firmly press the DIMM straight down
into the connector by applying pressure on both ends of the DIMM
simultaneously. The retaining clips snap into the locked position when the
