It's is not difficult to changing a laptop processor once the laptop is disassembled. The most challenging thing about working on laptops is the small size of the components. It's also very easy to reassemble parts in the wrong order.

Most laptop manufacturers have detailed diagrams and manuals that explain how each component fits in the housing. The laptop owner's manual also has information about the kind of processor you need for your particular model.
1) Before start you need to refer your laptop owner's manual and assembly guide as you disassemble the laptop. Touch something metal periodically to remove static charge, and work on a large table with a bright light source.
2) Turn off the laptop and unplug it. Remove the main battery, CD/DVD drive and the hard drive. The hard drive is usually located in a slot on one side of the laptop. Remove the screw that holds the cover in place, and then pull the hard drive sled out.
3) Turn the laptop over and remove the screws on the bottom that hold the keyboard in place. Some of the screws may be covered with stickers or rubber plugs. Flip the laptop over, open it, and then lift the keyboard up and out. Unplug the flexible ribbon cable that connects the keyboard to the motherboard.
4) Unplug the heat sink fan. Remove the screws that hold the heat sink in place, and then remove it from the laptop. Release or unscrew the mechanism that holds the original processor in place, then remove it from the laptop.
To remove the CPU there will be a screw with a padlock symbol, or a bar that you pull up to unlock the CPU from the socket
5) Apply a thin layer of thermal compound on the processor. Make sure it is securely attached and properly aligned in the CPU housing.
Note: Be very careful with the pins, they can easily be bent, and match the pin set, there is a pattern and match this pattern to the socket. Also CPU should fall easily into the socket DO NOT force it.
Next lock that into place, and on top of the CPU put a small pea sized amount of thermal paste, Arctic silver is good.
6) Now replace the heat sink and fan. Replace the screws, then plug the CPU fan back in.
7) Connect the keyboard to the motherboard temporarily. Plug in the laptop, restart it, and then follow the instructions in your owner's manual to enter the system's BIOS. The new CPU should now be recognized by the BIOS. Turn off the laptop, unplug it, and then remove the keyboard. (BIOS will detect the new CPU, and windows will install the new drivers)
8) Do not strip or over-tighten the screws. Follow the guide carefully as you reassemble the laptop. Replace any round stickers or rubber plugs you removed to complete the upgrade.
