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.

Chris,
I don’t have this laptop in front of me and cannot take a closer look, but isn’t it in the hole for the display hook under the right touch pad button? I’m just trying to guess.
Nope, it’s not built into the hinges.

Hi,
I have a PCG-K33 and I’m having the same problem as Gachet with the lid always thinking it’s closed. He said that he cleaned up the lid contactor? I don’t see a lid contactor anywhere on this laptop. I’m guessing that the lid open/closed sensor is probably built into the hinges. If that’s the case, did he just dip them in alcohol to clean the contacts?

Mike,
Did you check if there is BIOS update for your laptop? Maybe it’s a known issue and the latest BIOS release fixes this problem.

Hi,
In reference to #39 and #41. I have a PCG-K25 doing exactly the same thing when I tried to upgrade the memory. I’ve tried different modules and I tried switching from one socket to the other. Each socket reads the same as the other so it is not a socket issue. Any ideas? Thank you.

Thanks a lot, I used it to change the dc connector of my pcg-k35, I noticed the metal cover in step 7 has the holes for the fans, mine doesn’t have them, I have been having overheating problems, could that be the reason?
Thanks again
Santi

The external monitor works fine. I was in doubt about the card so your comment is right. I will go after a replacement LCD in my country.
Thanks a lot and Greetings from Brazil!

Gilberto,
It’s hard to tell. You’ll have to test the laptop with an external monitor. If external video works fine, apparently there is a problem with the LCD screen or video cable.
If both internal and external video fail, there could be a problem with the system board or video card.

Hi
Great guide here. Lots of usefull info.
I received as a gift a Sony PCG-k35, but the LCD probably has gone.
The screen keeps all bright (full white to gray) flashing. Sometimes the image comes ok, but appears this component is gone. I tried to reinsert the main flat cable in the LCD back area, and I noticed another small flat cable in the LCD circuit, but too thin and I really became afraid of trying to move it as appears to be hard fixed in place.
There’s a chance to be the LCD in fault of may the video card also cause this kind of problem?
Thanks in advance!

Taras,
It’s possible that one of the memory slots is bad and “cannot see” the memory module installed in it.
Test your laptop with different memory modules installed into different slots. If the laptop works fine with both memory modules in the slot A but not in the slot B, the slot B is defective. If that’s the case, you’ll have to replace the motherboard or use the laptop as is with only one working slot.

Hi,
As I guest in my last message it was a pb with lid contactor.
I disassemble my computer and “clean up” the lid contactor. Now it’s working well (with ACPI support).
Many thanks for your help.
