As new computer software is introduced and upgraded, faster and more powerful hardware will be required faster to operate it. Performance-enhancing devices, such as the hard drive, RAM and processor are among the most commonly replaced laptop hardware. But replacing your Sony laptop's hardware is no simple task. Removing any hardware device from a Sony PCG-Series laptop will require disassembly, which can be risky. If you dismantle the Sony laptop incorrectly, you can cause serious damage in the process.
Power down the laptop. Unplug the power cable from its socket. Pull the display panel closed, and place the laptop face down on a flat surface. Orient the computer with the front opening facing forward. Remove the battery pack from its compartment in the lower left corner of the laptop.
Remove the two hardware compartment covers from the centre of the laptop's bottom casing. Each cover is secured in place by a single Phillips-head screw. The compartment on the left is the hard drive compartment; the compartment on the right is for RAM.
Remove the Phillips-head screws that secure the hard drive to the compartment. Slide the hard drive downward until it disconnects from the compartment. Lift the hard drive out of the laptop.
Pull apart the retaining clips on each side of the RAM module with your fingertips. Tilt the RAM module upward, and remove it from its memory module. Repeat the process for all modules inside the memory compartment.
Remove the modem compartment cover situated at the top edge of the laptop's bottom casing above the hard drive compartment. Remove the modem's two retaining Phillips-head screws, and then lift it up out of the compartment slightly. Disconnect the modem's cable from the motherboard. Remove the modem from the laptop. Remove all unmarked screws from the laptop's bottom casing. Place the laptop vertically with the back edge facing upward. Remove the two Phillips-head screws.
Place the laptop face up, and pull open the display panel. Pry the keyboard strip from the laptop with a flathead screwdriver. The keyboard strip is a thin piece of plastic that spans the laptop's width above the keyboard. Place the keyboard strip face down on the laptop's surface. Disconnect any cables from the strip.
Remove the Phillips-head screws from behind the keyboard's top row of keys. Place the keyboard face down, and unplug the keyboard's motherboard cable. Remove the keyboard from the laptop. Remove all screws that secure the motherboard's metal cover, revealed by the keyboard assembly. Remove the metal cover from the laptop.
Unplug the LCD and Wi-Fi antenna cables extending from the left side of the display panel to the motherboard. Remove the Phillips-head screws from each display hinge. Remove the display assembly from the laptop's base. Remove the laptop's top cover to reveal the laptop's internal components.
Locate the CD/DVD drive on the right side of the motherboard. Grasp the back side of the drive, and push it out of its compartment.
Use an anti-static wrist strap or touch a grounded metal object to prevent static electricity damage to the computer or yourself.
