Installing a memory module
To install a memory module, do the following:
1. Turn off the computer.
2. Disconnect all cables, power cords, and external options from your computer. See “Rear connectors”
on page 65.
3. Place a soft, clean towel or cloth on the desk or surface. Hold the sides of your computer and gently lay
it down so that the screen is against the surface and the cover is facing up.
4. Remove the computer cover. See “Removing the computer cover” on page 70.
5. Replace the memory module by aligning the notch on the memory module with the key in the slot.
6. Firmly press the memory module 1 straight down into the slot by applying pressure on both ends of
the memory module simultaneously. The retaining clips 2 snap into the locked position when the
memory module is firmly seated in the slot.
Note: If there is a gap between the memory module and the retaining clips, the memory module has not
been correctly inserted. Open the retaining clips, remove the memory module, and then reinsert it.
