Your computer has two slots for installing or replacing DDR3 SODIMMs (small
outline dual inline memory modules). When installing or replacing a memory

a maximum of 4 GB of system memory.

1. Remove all media from the drives and turn off all attached devices and the
computer. Then, disconnect all power cords from electrical outlets and
disconnect all cables that are connected to the computer.
2. 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.
3. Remove the computer cover. See “Removing the computer cover” on page 16.
4. Locate the memory slots. See “Component locations” on page 12.
