The following disassembly guide will explain how to take apart a Sony Vaio PCG-K series notebooks. I created this guide while taking apart a Sony Vaio PCG-K25 notebook but I think you can use the same disassembly steps for all notebooks in PCG-K line.
The main reason to open up the laptop was replacing broken power jack. Proceed disassembly on your own risk.
Update: I just created a new guide for Sony Vaio PCG-K series laptops. It explains how to remove and replace LCD screen with inverter board.
Before you start laptop disassembly, unplug the AC adapter and remove the battery.

Hello i received one of these machines on trade and when I plug in the AC adapter I get flashing yellow LED on the battery indicator. Also it will run well on battery until it dies but if I plug the AC adapter in while it is running it will inexplicably shut down as though it lost all battery power. I replaced the battery charging board, reseated the CPU, and applied new thermal grease to the heatsink. I have 2 different adapters and 2 seperate batteries all with the same problem. What would you reccomend be my next course of action?

Thanks for the information and pictures re: removing the keyboard from my PCGK35. All went well. Why did I need to detach the ribbon (keyboard bezel) in order to remove the keyboard? It seemed as if I could have avoided this step.
In order to make sure it was a faulty keyboard, I removed the keyboard and used air to clean the board. Key number 7 did not function. When I reattached the keyboard, the same problem continued and I ordered a new keyboard. When the new keyboard arrives, I would like to avoid detaching the keyboard bezel if possible. I would appreciate your advice. Again thanks for your help and pictures.

I have a K15, replaced my old motherboard due it won’t turn on at all, checked everything and all’s fine but somehow still won’t work and now replaced a refurbished K13,fortunately it works but there’s a problem. The Wi-Fi doesn’t work. It won’t receive or transmit. The switch at the front when you slide it to the right, the green light turn on but it won’t pickup any signal at all. How can i solve this?

Phyre763,
1. Clean old thermal grease from the CPU and heat sink with paper towel and 99% alcohol.
2. Make sure the CPU is seated correctly. It’s possible you pulled it from the socket while removing the heat sink. Reseat the CPU and make sure the socket is LOCKED.
3. Apply a drop of fresh thermal grease on the top of the CPU.
4. Install and secure the heat sink.

I have a K35. I am having the same over heating problem as many others. I took my laptop to step 8 but I started reading ahead and did not see a step that involved the heat sink. I think the thermal paste has dired up an I need to replace it. How do I do this?

@ Ron Pistell:
what a rude and ungrateful comment, was this post aimed specifically at you?
The info provided was extremely helpful, I also didn’t need the whole thing but who cares?! The article wasn’t written for my or your benefit alone!

The information you provided was far more than I needed and consequently it took some time to pinpoint what I was looking for. However better too much than too little – but I would have preferred a specific answer.
