Items you will need
Antistatic wrist wrap
The central processing unit (CPU) is the device in your computer that operates and controls all software actions on your laptop. The speed and performance of your software is largely dependent upon the speed of your CPU. Upgrading your CPU requires the complete disassembly of your Sony Vaio laptop.
Turn off your laptop, disconnect the power cable and remove the battery pack and any cables or external devices.
Attach an antistatic wrist wrap to your wrist, and then attach the wire clip to the laptop casing or chassis.
Place the laptop face-down. Remove the two Phillips-head screws securing the RAM module cover in place. Remove the cover from the laptop casing and set it to the side.
Remove the remaining nine Phillips-head screws from the bottom casing.
Place the laptop face-up, and then open the liquid crystal display (LCD) display as far as it will go. Use a flat-head screwdriver to pry up the retaining tabs behind the F4 and F12 keys. This will detach the keyboard from the laptop base. Use the flat-head screwdriver to lift the keyboard out of the laptop base. Place the keyboard face-down over the palm rest, and then disconnect the keyboard's ribbon connector from the motherboard.
Remove the remaining Phillips-head screws securing the motherboard cover to the laptop base. Disconnect the two ribbon cables and the two wire latches from the Vaio's mother board. Use a flat-head screwdriver to remove the motherboard covering from the laptop base. Remove the cover and set it to the side. This will expose all of the interior components of your laptop.
Remove the three Phillips-head screws securing the heat sink to the laptop motherboard. Note that one of the screws is spring-loaded. The heat sink is a large metal piece with a long piece of copper extending out of it. Lift the heat sink out of the motherboard.
Use a flat-head screwdriver to turn the CPU's single flat-head locking screw. Lift the CPU out of the motherboard and set it to the side very carefully.
Install the new CPU by repeating the previous steps in reverse order.
Disassembling your Viao may void your warranty.
