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.

Penny F,
Technically, you are “not supposed” to replace the tip because it’s permanently attached to the power cord. But in real life, you just cut off the melted tip and solder a new tip if you can find one.
Check out here: http://www.computekinc.us/TheEndConnectors.htm
They have a few power tips available and one of them is for Sony laptops. Maybe it’s similar to yours.

I re-read this “I have ordered a new jack, due to the melt down, is it possible to replace the tip on the a/c adapter or should I replace it(THE WHOLE ADAPTER) due to the melt down??”
Is it possible the adapter caused the over heat?

So to help me clairify this in my little mind, the Sony A/C adapter (19.5) that came with the Vaio is the correct one. And this should charge a 14.5V battery in the computer without a problem…. I have ordered a new jack, due to the melt down, is it possible to replace the tip on the a/c adapter or should I replace it due to the melt down??
Sorry, I don’t mean to sound so dumb and needy , but I am new at all this A/C to D/C stuff, I have more experience with PC’s than Laptops.

PennyF,
Nope, you should find a 19.5V adapter.

Awesome!!! Just Awesome!! I bought my Vaio at a garage sale for $25 and having said this I have no room to fuss, BUT…. it has a replacement battery in it which it will run on for about 15 – 20 minutes, but the ac/charger is original and is for a 19.5 system. Now this gives me cause for concern, the charger plug has been jury-rigged and has a “replacement” tip on it, today my hubby was using it, and the jack pushed into the housing of the laptop. (hence my coming across your awesome pages) so I took it apart and found that the jack was easily put back into place, BUT….. it was also mis-shappen. upon inspection of the charge tip, I can see that it has melted the plastic around the tip and it is now larger than the hole in the jack (technicly a jill??) anyway this was the reason the jack had been pushed into the case of the laptop. NOW my question is should I replace the charger with a 14.5V, the battery, (can’t seem to locate a 19.5V sony offers places where a 14.5v is easily available) and should I also replace the Jack? Weehuu, that was a mouth full. Hope you don’t mind my asking, and Thanks a bunch in advance for your time!!!!

Thanks for the detailed directions for breakdown. I used it to replace the broken insulator (and wiring harness) on my Sony PCG-K45. I couldn’t have done it without your help, you are a lifesaver! No leftover parts except for a large “Elongated – C” shaped rigid metal wire which fell out of the keypad upon removal. it was the approximate shape and size of the “space bar” so I just tucked in up under there on re-assembly and away I went! Works fine though! Thanks again!

Deepak “I try to replace the LCD plastic case and front bezel using the guide above. Everything was done and also reassembled. I had removed the unit holding the wificable. But I am sure I recoonected it as it was before.
Now the laptop is not booting up. Can you suggest any help in getting this resolved.
Thanks for all your valuables suggestions in advance.”
when you press the power on button does the battery and power light blink? If so, or even if not its more than likely that you just didnt seat your cpu in tightly enough, try pressing down really hard on the cpu and starting the computer. If it starts let go of the cpu and take it all apart and try fitting it in tightly so it starts Up again.

Hi, great guide I used it to replace my dc power jack on my pcg-k33. Anyways I put it back together and it wouldnt start. All that needed to be done is the cpu and heatsink to be reseated but now my screen doesnt even turn on anymore. And since I have a password on my user account I dont even know if it really starts up or not. The fans turn on and the seat hink gets hot to the touch. I just really need help. I made sure the video cable is connected tightly, I took it apart at least 5 times to try and fix it now. I checked the little button the lid presses when closed to shut the screen off, its not that. I am just really in need of any help. Thanks.
