Removing the Memory Modules
1. Remove the memory module cover .
2. To release a memory module from its connector, spread apart the inner tabs of the memory module connector just far enough for the memory module
to disengage from the connector. The module should pop up slightly.
3. Lift the memory module out of its connector.
Replacing the Memory Modules
1. If you only have one memory module, install it in the connector labeled "JDIM1." If you have two memory modules, install the second module in the
connector labeled "JDIM2."
2. Align the memory module's edge connector with the slot in the center of the memory module connector. With the module at a 45-degree angle, press
the memory module's edge connector firmly into the memory module connector.
3. Pivot the memory module down until it clicks into place. If you do not hear a click, remove the memory module and reinstall it.
4. Insert the tabs on the memory module cover into the bottom case assembly. Rotate the memory module cover down and tighten the two captive
screws.
Mini PCI Card Assembly
The optional Mini PCI card assembly may contain either a modem, network adapter, or combination of both. You must remove the Mini PCI card subassembly
before the system board assembly can be removed. The Mini PCI card subassembly must be connected to the internal antenna for proper operation.
