Viewing the amount of memory
1 Restart the notebook.
2 Click Start on the Windows® taskbar, select VAIO, and then click “Sony
Notebook Setup.” The Sony Notebook Setup screen appears.
3 Click the “About This Computer” tab to view the amount of system memory.

“Installing a Memory Module” section.
✍
The amount of memory displayed in the Sony Notebook Setup screen is not always
correct. The video adapter uses some system memory, and that amount of memory
does not appear as part of the total memory shown in the Sony Notebook Setup
screen.
