The CPU is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computer's functions. The processor is essentially the brain of the VGN-FZ18 battery laptop , with faster processors leading to faster computing time. So if our laptop CPU failed, our laptop can not start and work. We must remove the CPU and replace a new one. Sometimes the old version CPU can not afford our working and playing work, the laptop become very slowt then we should replace them.

Follow these instructions before beginning.

• Remove the CPU thermal cooling system
• NOTE: To prevent damage to the VGN-FZ140N battery CPU, hold the screwdriver so that is perpendicular to the lever of the CPU when turn the screw off.
• To loosen the ZIF socket, use a small screwdriver and rotate the ZIF socket cam screw counterclockwise until it comes to CAM-Stop.

• NOTE: To play the maximum cooling of the CPU , do not touch the heat transfer areas of VGN-FZ150E battery CPU thermal cooling assembly. The oils of your skin, can reduce the ability of transfer heat from a heating pad.

  NOTE: When removing the CPU, pull the module up. Be careful not to bend the pins of the CPU.

• Lift the CPU ZIF socket.

Replacing the CPU

NOTE: Do not touch the CPU die. Press and hold down the CPU on the substrate mounted by the dice, while the screw to prevent intermittent contact between the screw and the CPU.

NOTE: Make sure the cam lock in the fully open position before inserting the VGN-FZ160E battery CPU. Be the CPU correctly in the ZIF socket does not require force. A CPU is not positioned correctly can result in a dropped connection or permanent damage to the microCPU and ZIF socket.

NOTE: If a new CPU is installed, you will receive a new thermal cooling assembly, installation of a heating pad or you will become a new heating pad with a sheet containing an appropriate facility to illustrate.

• Align the pin 1 corner of the CPU with pin-1 corner of the ZIF socket, then insert the VGN-FZ180U battery CPU.Note: The pin-1 corner of the CPU is a triangle, which coincides with the triangle in a corner pin ZIF socket

  If the CPU is in place, the four corners are aligned at the same height. If one or more corners of the module higher than the other does not, the module is correctly aligned.

  NOTE: To prevent damage to the CPU, hold the screwdriver so that is perpendicular to the lever of the VGN-FZ220U battery CPU to turn the screw.

• Pull the ZIF socket by turning the screw clockwise to the CPU, to ensure secure CPU to the motherboard.
• Replace the VGN-FZ260E battery CPU cooling thermal assembly (see Replacing the Cooling Assembly CPU heat).
