Removing the System Memory (RAM)
The computer has two memory sockets for 260 pin Small Outline Dual In-line Memory Modules (SO-DIMM) supporting
DDR4 2400 MHz. The main memory can be expanded up to 16GB. 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, turn it over, remove the battery (
page 2 - 5
).
2.
The RAM-2 modules will be visible at point
on the mainboard (
Figure 5a
)
.
3.
Gently pull the two release latches (
&
) on the sides of the memory socket in the direction indicated by the
arrows (
Figure 5b
).
The RAM module
will pop-up
(
Figure 5c
)
, and you can then remove it
.
4.
Pull the latches to release the second module if necessary.
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 cover and the screws
(see
page 2 - 7
)
.
9.
Restart the computer to allow the BIOS to register the new memory configuration as it starts up.
