Replacing the Memory Module
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 cover and screws.

NOTICE: Ensure that memory modules are installed in both connectors and that they are of the same capacity. Install a memory module in the
connector labeled "DDR2 DIMM A" before you install a module in the connector labeled "DDR2 DIMM B." Insert memory modules at a 45-degree angle to
avoid damaging the connector.
NOTE: If the memory module is not installed properly, the computer will not boot.
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.
