If you want to increase your computer’s speed or improve performance when running programs simultaneously, increase the amount of memory by installing optional memory modules.
Before you upgrade your computer’s memory, see Notes on Adding and Removing Memory Modules.
If you install memory modules into two or more slots, the dual-channel mode is enabled to help improve performance.
The type of module and the amount of memory installed on your computer may differ depending on the model.
See Removing the Battery Pack for information on how to remove the battery pack.
The inner parts of your VAIO computer may be hot just after turning off. Be careful to avoid burns while handling your VAIO computer in this state.
The screw locations are indicated by the arrows in the illustration below.
On some models, captive screws are used on the memory module compartment cover and cannot be detached from the cover.
A protective sheet covers the memory module under the cover. Lift the sheet when installing/removing the memory module.
Be careful not to lift the sheet so much that it is detached or folded back.
Do not touch any metal parts inside your VAIO computer.
The latches on both sides of the slot snap into place to secure the module. Do not touch any ICs (black components) on the memory module.
If the amount of indicated system memory is correct, memory module installation was successful.
To check the system information, see Viewing the System Information.
