The following guide will explain how to disassemble a Sony Vaio PCG-K series laptop.
I created this guide while taking apart a Sony Vaio PCG-K25 model but I think you can use the following disassembly steps for all models in the PCG-K line.
The main reason for me to take it apart was replacing the broken power jack. Proceed disassembly on your own risk.
Before you start the disassembly process 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 bezel upside down. The red arrow pointing to the connector on the motherboard.

STEP 3
Unlock the connector by lifting up the cable retainer about 1-2 millimeters. Be very careful.
After the connector is unlocked, you can pull the cable and remove the bezel.

STEP 4
Remove three screws from the keyboard.

STEP 5
Lift up the keyboard and place it upside down on the palm rest so you an access the cable underneath.
Unlock the cable connector. Disconnect the 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 the 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.
In one of the next guides I explains how to replace LCD screen with inverter.

STEP 11
Lift up and remove the display panel.

STEP 12
Remove the hard drive cover, memory cover and modem cover from the bottom.
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 slot. The memory module will pop up at 30 degree angle. Pull the 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.

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 broken power jack (unsolder from the harness) and replace it with a new one.

246 Frustrated.
Had a similar problem – not my laptop. Maybe I got lucky but I found that inserting the appropriate memory card permitted the thing to boot (would not boot without the card). Once in windows I disabled the slot in device manager and it seemed to work OK – obviously the slot does not work. I have not tried it (not my machine) but I have seen reference to the fact that sometimes you can leave the card in whilst booting and then once you are booted you can use it as normal (remove/replace the cards as you need them) but you must have a card in when you boot it. I have also seen that, in the most severe cases, you have to leave the card in AND disable it in Device Manager (obviously the card slot then cannot be used). If you are game for it I have also known people simply diassemble the machine (as above) and simply remove the thing! I am no expert but it seems to be an issue with the “card inserted or not” detection when booting. Hope it helps!

Hello IML Tech,
I have sony vaio pcg-k23, the problem I’m having is that, cannot see my HDD. Went to bios to check the Primary IDE= None. So I bought a new HDD to make sure its not the HDD but unfortunately it’s the same result. Tried to open the laptop based on your pix and by the way its awesome- to reset my bios by pulling out the cmos battery for 15 min then put it back but still the same result. Do you have any idea how to resolve this?
Thanks

ekau spephen uganda,
What kind of lines? Vertical, horizontal? Are they flickering? Can you make them go away by moving the display?
Also, did you check your laptop with an external monitor? Do you see same lines on the external image?

Hello,
I have a PCG-K25 that has just started acting up. Laptop boots up, gets to Windows logo and just freezes (the little scrolling bar underneath the logo moves about 3 times). When it freezes, I noticed that the LED for the memory slot is illuminated (just to the left of the wireless switch). Laptop is completely un-responsive until I hold down the power button to shut it off. I can get to the BIOS just fine. Starting in safe mode also seems to work fine (or used to).
Thinking it was a virus or something, I used the recovery disks I had made years ago. Problem now is that the OS is not completely installed, as when it re-starts to finish the OS installation it just freezes at the windows logo again. Safe mode no longer works, as now getting error message of “the system has not been installed” or something like that.
I am thinking it is an issue with the pro media memory slot itself (hardware). Since I can’t get into device manager via safe mode to disable it, is there a way to physically disable it so I can try again. Thanks in advance!

Enzo,
This sounds like keyboard related problem. You’ll have to use the keyboard as is or replace it with a new one.
Yes, if you have Wi-Fi antenna cables installed. The wireless card slot located under the keyboard. You can see it in the step 9, on the left side from the cooling fan. You can remove the keyboard and take a look at the slot. Do you have Wi-Fi antenna cables in there? If yes, you can install internal Wi-Fi card.
Keyboards are not serviceable. If your keyboard goes bad, you replace it with a new one.
That’s right. 64MB used by the video card.
Yes, it should work with 1GB RAM (two 512MB sticks).
