Removing the Primary System Memory (RAM)
The computer has four memory sockets for 260 pin Small Outline Dual In-line (SO-DIMM) DDR 4 type memory modules.
The total memory size is automatically detected by the POST routine once you turn on your computer.
Note that four SO-DIMMs are only supported by Quad-Core CPUs; Dual-Core CPUs support two SO-DIMMs maxi-
mum.
Two primary memory sockets are located under component bay cover (the bottom case cover), and two secondary
memory sockets are located under the keyboard (not user upgradable). If you are installing only two RAM modules
then they should be installed in the primary memory sockets under the component bay cover.
Note that the RAM located under the keyboard is not user upgradable.
Memory Upgrade Process
1. Turn off the computer, and turn it over, remove the battery (page 2 - 5).
2. The modules will be visible at point (Figure 6a
).
3. Gently pull the two release latches (
& ) on the sides of the memory socket(s) in the direction indicated below
(Figure 6b
).
4. The RAM module will pop-up, and you can remove it (Figure 6c
).
