CHAPTER 4 SERVICE PROCEDURE
3.2 TO CHECK MOTHERBOARD DIMM CONNECTIONS
1. Check that all DIMMs are locked. If any DIMMs have come loose, release and reseat
them.
The DIMMs (dual in-line memory modules) on the motherboard are held in place by
levers at each end. Sockets 1-4 on the motherboard hold the DIMMs.
2. To release a DIMM, push outward on the levers on each side of the DIMM.
3. Slide the DIMM straight out of the socket.
4. To replace a DIMM, gently slide the DIMM straight into the socket and close the levers
at each side to lock it into place.
Make sure that the levers close securely around the ends of the DIMM and that each
DIMM is fully seated in its socket.
If you removed the DIMMs completely, note that DIMMs fit the socket only one way.
The notches on the bottom of the DIMM should line up with the notches in the socket.
