Upgrading your VAIO computer
Adding / replacing a memory module
If you are not familiar with upgrading memory on a computer, we highly recommend that you contact your
dealer.
To add or change a memory module, proceed as follows:
1 Shut down the computer, unplug it, remove any peripheral devices and wait for the computer to cool
down.
The inside of the main unit becomes very hot during operation.
2 Locate and press the release button on the side of the system unit cover, behind the display.
