A screwdriver is the only tool you’ll need to open the memory compartment on your Vaio.
Unlike many other laptop computers, there are two RAM (Random-Access Memory) slots in the memory compartment of your Sony Vaio laptop. There’s no need to let this extra module intimidate you, because if you need to install new memory you only need to remove and replace one of the modules. Even if you do decide to upgrade both modules, you’ll find that the process is the same for both. These modules are easily accessible from the bottom side of your computer.
1. Turn off your Sony Vaio and unplug the power cable. Turn the laptop upside down and slide the battery out of its compartment on the bottom of the computer.
2. Locate the rectangular memory compartment in the middle of the underside of the computer. It is secured with only a single screw.
3. Use your Phillips screwdriver to remove the single screw holding the compartment cover in place. Then lift up the compartment cover. Two rectangular memory modules will be exposed in the compartment.
4. Pull the tabs at either end of one memory module outward and the module will pop out of the compartment at a 45-degree angle. Slide it gently out of the compartment. Repeat the process with the other module if you intend on replacing both modules.
5. Fit the new module in the socket and gently press it down until the tabs lock in place. If you are only replacing one module, make sure the megabytes (MB) listed on the front of the module matches the megabytes listed on the other module. If you are replacing both modules, make sure they both have the same amount of megabytes.
6. Replace the memory compartment cover and screws.
