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.
Are you looking for spare parts for your Sony Vaio PCG-K series notebook? Search here.
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 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.
Static electricity can kill your laptop. I recommend wearing an anti-static wrist strap while working with internal parts of your laptop.

Thank you so much! It is IDE. I know what I’ll be doing this weekend!

erin,
Do you know if your laptop has IDE or SATA hard drive installed? Most likely it’s an IDE hard drive but I’m not sure 100%.
If it’s an IDE hard drive, I think you can safely install a 160GB drive. I don’t know if the BIOS in your laptop can support larger drives.

wow! I’m so glad I found this page, this has been a huge help. I have a PCG-K15 and I’m looking to replace the harddrive as the one I have now is the 60GB stock one and it fails a lot. Does anybody have a suggestion for what would be compatible with this computer? I want to go as big as possible without changing anything else.
thank you!

Geoff,
1. Try cleaning the recovery disc.
2. Run diagnostic test on the hard drive. Maybe the hard drive is going bad.
You can use Hitachi’s DFT test. Download an ISO image, burn it on a CD, boot the laptop from the CD. Test the hard drive.

Can you tell me where I can get a motherboard for the PCG-K45 model of the Sony Vaio. The one I have here is dead. I need to get a new system board for this dead.

I have replaced the dc jack with a replacement and followed the instructions above to disassemble the laptop. When I did and put the laptop back together there is no video. I have retraced my steps twice over but still do not know what is wrong. Thanks for any help.

I have had a quick look at the intructions/photos and they look really useful and helpful.
However, I have a sony PCG-GRT995MP – do you know are your instructions for replacing the broken power jack for the PCG-K the same/similar for my machine ?
Would really appreciate some guidance before I attempt to dissemble my laptop to repair the power jack.
Many thanks, Derek

Hi
Got a weird problem with a PCG-K33. It will charge the battery up and the laptop will work for about 20 to 25 minutes roughly on battery and will not shut off. However when i try to run on AC, The laptop will turn on and run but will randomly shut off. I noticed however either running on Battery or AC the screen will sometimes “wobble” and that it will slightly get darker for a second or too. All the drivers seemed to load up fine. Any thoughts would be sincerly appreciated. Also this sight is PHENOMENAL!!

Instead of unsoldering the wire to the jack…I just ripped it out of the old jack. I guess I can still unsolder the guts of the old power jack and then solder the wire back on to the new one? If I can’t unsolder the gust of the old jack can I just cut them off. What does the wire look like unconnected to the power jack?
Thanks for the great directions…it’s a shame we all got stuck with a laptop which overheats and destroys it’s own parts. Already replaced the harddrive.

Hello
Thanks for this great guide. I have a question: Did you try to change cpu with another more powerful but of the same specification? I have a pcg-k115b and I have already done the easy job: New hdd and more ram. I want now to change the celeron 2.8 cpu 533 478 with another mobile cpu 3.06 GHz 512/533 478pins. What do you think? Will be accepted from the mobo this changement?
Thanks a lot for your answer
July 6th, 2009 at 10:38 pm
Tee,
I remember reading about the solution for that but cannot find where. I believe you’ll have to short a couple of pins on the wireless card but I could be wrong. Try searching this direction.

Hi
My PCG-K315S came without a wireless card, so i decided to install one. Stripped it and found the slot, installed the card and antenna. Now windows tells me that the hardware switch is in the off position. I cant for the life of me find???
Can someone tell me where this is? Could it be the jumpers next to the slot?
Please help!
Thx

I’m having the same issue as Lexi. My laptop won’t turn on anymore. It does the brief noise for a second, but then doesn’t turn on. I replaced the fan using the instructions on this page.
Please help.
Thanks,

I have a Sony Vaio PCG-K27 and I have taken my computer apart and put it back together several times without any problems. I found this website after frantically trying to figure out what I did wrong this time because my computer doesn’t turn on anymore. I had to get a new cpu, because somehow, I accidentally broke off one of the pins on my cpu when I got distracted. My minor question is: Does that mean that I need to put that grease on it? There is still a bit of it attached to the fan.
My major question is: How do I turn my computer on again? I reseated the new CPU several times. Everytime I try to turn my computer on again, it makes a very nasty sound near the dvd-rom and hard drive. I know that my hard drive is about to fail, however, it turns on in my mom’s computer (She has the same computer as me.). So that cannot be why it doesn’t turn on. I tried to turn my computer on with the memory and hard drive from my mom’s and the computer doesn’t turn on. I’m trying to figure out if I may have knocked the IDE connector out somehow, because that is the only possible cause that I can come up with to explain why the computer makes that nasty noise when trying to turn on.
This noise lasts for about 1-2 seconds. The fans turn on perfectly for that time and then slowly turn off. The power light turns on and then turns off in that time.
I will greatly appreciate any and all help. Thank you!

Thanks Laptop Tech for your answer
No I didn’t remove the memory modules.
I asked a computer Tech today and he told me it might be the power ribbon (flat cable between the power button and mainboard ) which could be broken.
I’m looking for a PCG-K415s power ribbon now … If someone has any adress to get it.
Thanks

Bounch,
Did you remove the memory modules while cleaning the laptop? Make memory modules are installed correctly.
