Removing the System Memory (RAM)
The computer has one memory socket for 204 pin Small Outline Dual In-line Memory Modules (SO-DIMM) supporting
DDR3 1333/ 1066MHz. The main memory can be expanded up to 4GB. The SO-DIMM modules supported are 1GB,
2GB and 4GB and DDRIII Modules. 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 the component bay cover ( page 2 - 8 ).
2. The RAM modules will be visible at point on the main board
.
3. Gently pull the two release latches ( & ) on the sides of the memory socket.
4. The RAM module will pop-up, and you can then remove it.
5. Insert a new module holding it at about a 30° angle and fit the connectors firmly into the memory slot.
6. The module’s pin alignment will allow it to only fit one way. Make sure the module is seated as far into the slot as it
will go. DO NOT FORCE the module; 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 bay cover by inserting it at an angle and aligning the cover pins.
9. Replace the screws ( make sure you reconnect the fan cable before replacing all the screws and screwing
down the bay cover ).
10. Restart the computer to allow the BIOS to register the new memory configuration as it starts up.
