Replacing the Memory Module(s)

NOTE: To get maximum performance/dual-channel memory bandwidth capability, both memory module connectors must contain memory modules and the modules must be of the same size and configuration.

NOTE: If a memory module is not installed properly, the computer does not boot.

1.Ground yourself and install the new memory module:

a.Align the notch in the module edge connector with the tab in the connector slot.

b.Slide the module firmly into the slot 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.

2. Replace the memory module cover and tighten the captive screws.

NOTICE: If the memory module cover is difficult to close, remove the module and reinstall it. Forcing the cover to close may damage your computer.

3.Insert the battery into the battery bay, and connect the AC adapter to your computer and an electrical outlet.

4.Turn on the computer.

As the computer boots, it detects the additional memory and automatically updates the system configuration information.

NOTE: Since the computer operating system reserves some memory for system files and activities, the amount of available memory that is displayed will be less than the total memory installed. If you install two 2-GB memory modules for a total of 4 GB, the memory total is reported as being less than 4 GB in the system setup program and by the Microsoft® Windows® operating system.
