NOTICE: If you need to install memory modules in two connectors, install a memory module in
the connector labeled "DIMMA" before you install a module in the connector labeled "DIMMB."
Insert memory modules at a 45-degree angle to avoid damaging the connector.
NOTE: If the memory module is not installed properly, the computer may not boot properly. No
error message indicates this failure.
4. 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.
5. Replace the memory module cover and tighten the screw.
NOTICE: If the cover is difficult to close, remove the module and reinstall it. Forcing the cover to
close may damage your computer.
6. Insert the battery into the battery bay, or connect the AC adapter to your computer and an
electrical outlet.
7. Turn on the computer.
As the computer boots, it detects the additional memory and automatically updates the system
configuration information.
To confirm the amount of memory installed in the computer, click the Start button, click Help and
