Memory Modules, Mini PCI Card, and Modem: Dell Latitude C540/C640 Service Manual

Replacing the Memory Modules

1. If you only have one memory module, install it in the connector labeled "JDIM1"

on the system board. Install a second memory module in the connector labeled

"JDIM2."

NOTE: Memory modules are keyed, or designed to fit into their sockets, in only

one direction.

NOTICE: The memory module must be inserted at a 45-degree angle to avoid

damaging the connector.

2. Align the notch in the memory-module edge connector with the tab in the

socket.

3. Slide the edge connector of the module firmly into the socket at a

45-degree angle, and rotate the module down until it clicks into place. If you do

not feel the click, remove the module and reinstall it.

4. Replace the memory module cover and tighten the two captive screws.

Mini PCI Card

You must remove the Mini PCI card before the system board can be removed.

Removing the Mini PCI Card

NOTICE: Disconnect the computer and any attached devices from electrical

outlets, and remove any installed batteries.

NOTICE: To avoid ESD, ground yourself by using a wrist grounding strap or by

touching an unpainted metal surface on the computer.
