Confirming added memory capacity
After you’ve installed a new memory module, make sure the operating system’s
memory corresponds with the memory upgrade.
To check your system’s memory
1 Turn on the computer.
2 Click Start on the Windows® taskbar, point to All Programs, and then
point to Sony Notebook Setup.
3 Select Sony Notebook Setup from the submenu. The Sony Notebook Setup
dialog box appears.
4 On the About This Computer tab, make sure the System Memory
displayed in the System Information box matches the amount of memory
installed.
The displayed memory may be less than the installed memory due to the
amount used by the display adapter.
