The computer has two memory sockets for 204 pin Small Outline Dual In-line Memory Modules (SO-DIMM) supporting
DDR3L up to 1600MHz. The total memory size is automatically detected by the POST routine once you turn on your
computer.
Memory Upgrade Process
1. Turn off the computer, remove the battery (page 2 - 5), and bottom case (page 2 - 6).
2. The RAM modules will be visible at point on the mainboard (Figure 5a).

5. Insert a new module holding it at about a 30° angle and fit the connectors firmly into the memory slot.
6. The module will only fit one way as defined by its pin alignment. Make sure the module is seated as far into the slot
as it will go. DO NOT FORCE IT; it should fit without much pressure.
7. Press the module in and down towards the mainboard until the slot levers click into place to secure the module.
8. Replace the bottom case and tighten the screws and cover (Figure 6d)
