Dell Inspiron 6400, 9300 & 9400 Memory Installation Guide
Removing the Memory Module(s) CAUTION: Before you begin the following procedure, see the safety instructions in the Product Information Guide.
NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface.
NOTICE: To help prevent damage to the system board, remove the main battery (see Before Working Inside Your Computer) before working inside the computer.
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.
1. Follow the instructions in
General Safety Guidelines. 2. Turn the computer upside down, loosen the two captive screws on the memory module cover, and remove the cover.
NOTICE: To prevent damage to the memory module connector, do not use tools to spread the securing clips that secure the memory module.
NOTICE: Handle memory modules by their edges, and do not touch the components on a module.
3. Use your fingertips to carefully spread apart the securing clips on each end of the memory module connector until the module pops up.
4. Remove the module from the connector at a 45-degree angle.
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.
