WARNING: Never open the cover while the power cord
is attached. You might damage your computer or be

Memory compatibility
The computer uses SODIMMs (small outline dual in-line
memory modules) that must meet the following
requirements:
● 204-pin
● DDR4-2133
● Unbuffered, non-ECC (64-bit)
● 1.2 V
● 16 GB maximum installable memory
Because the memory uses dual channels, you must use the
same memory module type for both sockets.
Tools needed
Phillips #2 screwdriver
Hex tool
Small screws are easily lost. Remove screws over a surface
that enables you to retrieve them if they fall.
Troubleshooting
If the computer displays a memory error after you have
turned it back on, turn the computer off and unplug the
power cord. Open up the memory compartment and make
sure the memory module is inserted all the way into the slot,
and then press down on it to be sure it is firmly seated.
NOTE: The actual memory transfer speed might vary,
based on the processor used in your computer.
NOTE: Memory performance might vary due to different
system configurations.
Removing the memory module

2. Using caution, lay the computer down on a flat surface
covered with a soft cloth.
4. To remove the rear cover, remove the two screw covers
(1) and two Phillips screws (2) located in the bottom of
the cover. Lift off the cover, and then place it upside
down next to the computer (3). The optical drive is
mounted on the inside of the rear cover, and a cable
connects it to the system board.
3. To remove the stand, rotate it upward (1), remove the
four hex screws (2), and then lift the stand up and off
the computer (3).
5. Locate the memory modules:
1. Hard drive
2. Memory modules
6. Remove the five Phillips screws that secure the system
board cover (1), and then lift the cover off the
computer (2).
7. Spread the two retention clips outward (1) until the
memory module tilts up at a 45-degree angle. Remove
the module (2). Use the same procedure to remove
both memory modules.
