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.

STEP 1
Carefully remove the keyboard bezel using a small flathead screwdriver. Remove it slowly, there is a flat ribbon cable connecting the power button board with the motherboard.

STEP 2
Trun the keyboard bezel upside down. The red arrow pointing to the connecto on the motherboard.

STEP 3
Unlock the connector by lifting up the top side of the connector 1-2 millimeters. Be very very careful. If you break any connector on the motherboard you are screwed big time. After the connector is unlocked, you can pull the cable and remove the keyboard bezel.

STEP 4
Remove three screws from the keyboard.

STEP 5
Lift up the keyboard and place it upside down on the palm rest. Unlock the keyboard cable connector on the motherboard. Disconnect the keyboard cable and remove the keyboard.

STEP 6
Remove all screws securing the metal cover.

STEP 7
Remove the cover.

STEP 8
After the cover has been removed, you can access and clean both cooling fans. You can clean fans with compressed air.

STEP 9
Remove two screws securing display hinges to the back side of the base.

STEP 10
Remove four screws securing display hinges. Unplug the video cable from the motherboard. Unplug both wireless card antenna cables from the wireless card.

STEP 11
Lift up and remove notebook display panel.

STEP 12
Remove hard drive cover, memory cover and modem cover from the bottom of the notebook. Each cover is secured by one screw.

STEP 13
Here’s how you can remove the hard drive. Remove four screws securing the hard drive caddy to the base assembly. Slide the hard drive down to disconnect it from the motherboard. Lift up and remove the hard drive.

STEP 14
Removing memory modules (if needed). Carefully spread latches on both sides of the memory slot. The memory module will pop up at 30 degree angle. Pull the memory module from the slot by the edges.
Removing modem card (if needed). Remove two screws securing the modem card. Lift up the modem card to disconnect it from the motherboard and unplug cable from the side.
Remove all screws from the bottom of the notebook

STEP 15
Remove two screws securing the top cover assembly. Disconnect the touch pad cable connector on the motherboard and unplug the cable.

STEP 16
Lift up and remove the top cover assembly.

STEP 17
Push the CD/DVD drive to the right side with your thumb. Remove the CD/DVD drive.

STEP 18
Remove three screws securing the plastic cover.

STEP 19
Remove the cover.

STEP 20
The power jack is hidden under the metal bracket. Remove one screw securing the bracket.

STEP 21
Lift up the bracket. Now you can access the power jack.

Release the power jack. Now you can remove the old power jack (unsolder from the harness) and replace it with a new power jack.

I may be misunderstanding something, but on my laptop, the cpu socket is attached to the motherboard. The cpu is soldered onto the underside of the cooling fan. I can see how to unlock the socket, but not how to reseat the cpu (as it is attached to the fan which completely covers the cpu socket) and then lock it again. Yet it must have been done properly when the computer was built. Is it possible to reseat the cpu while it is attached to the fan and the socket is locked–I can see no other way to do it unless I am missing something obvious. Is it possible to remove the cpu from the heatsink on the fan–it looks like it is soldered. It feels pretty solidly attached. Thanks so much for your help so far.
p.s. I just tried unlocking socket, reseating cpu/heatsink/fan structure without locking it, because I couldn’t reach it. It seemed to make a solid connection, but after reassembling, I’m back to the original problem. Again the lights blink once when the power button is pressed, then nothing.

Ash,
Did you separate the heat sink from the CPU during the laptop disassembly? If you did, it’s possible that you accidentally pulled the CPU from the socket. Remove the heat sink again, unlock the CPU socket, reseat the CPU and lock the socket. It’s possible that your CPU is not making good contact with the socket.
Check if the memory module is seated correctly. Reseat the memory module.

I used this great guide for the purpose of cleaning out the cooling fans (I cleaned out an astoninshing amount of dust and fur). My computer worked fine before I did this, but when I put it back together, I had the same problem as described above where when the power button is pushed, the power light blinks for one sec and then nothing. I followed the reccomendation for solving this problem and reseated all the connections. I found that the only one that was not properly seated was the memory stick cable. I also refit the fan (is the cpu on the underside of the fan?–mine is a pcg frv27). I did not apply new thermal grease. Now my computer will begin to start up, but only the power light stays on. It sounds like the hard drive is engaged just for a second and then stops–the computer remains on, but does not boot. I am almost there! Help!

When i take apart the laptop, the power button cable was unattached to the connector with force by accident. So then i plug the cable back again and it only lights up once and then it will not allow me to press the power button to turn on the computer. So, did i screw up the connector? If i did, but I don’t see the connector has any damage, i mean the connector still stay on the motherboard and is fine. So, that’s why i was talking about could it be possible that some part of the cable was damaged because of the unattached the cable with force.

Ken,
I’m not sure how you can break a flat cable. You can break a connector but not the cable. Maybe I’m missing something?
You see what I see. I cannot tell if that’s the cable you are looking for. You’ll have to contact the seller for more info.

Jorge,
It’s a special compound witch should be applied on the top of the CPU before you install the heatsink.
You can buy it in Radio Shack. Search for Arctic Silver® Silver 5 Thermal Compound. This compound suppose to be a good one.

What is this thermal grease, where could I get it. Radio Shack?
Thank you.

I found the cable on this website which seem to be exactly the same one, but i’m not sure if is the same. So, my question is, is this cable the right one for the power button cable? Please reply as soon as possible.

For this one, what happen if I accidentally force the cable to be disconnect it and break the cable, would i be able to replace the cable and fix it?

Jorge,
Yes, you can. Both cooling fans are attached to the heatsink, so you’ll have to replace the whole heatsink assembly.
1. Unplug both fan cables from the motherboard.
2. Loosen three screws on the heatsink. They are marked 1, 2 and 3.
3. Carefully lift up and remove the heatsink assembly.
4. Clean old thermal grease from the CPU and apply new grease.
5. Install new heatsink assembly.
