      @ Erika,
      I don’t have the motherboard removal guide for this laptop but it should’t be very difficult when you get to the step 18.
      Basically, you’ll have to disconnect all cables and remove screws securing the motherboard.

    I have a VPCSA2CFX. I disassembled it to clean the fan and mounted it again.

    Now there are some parts that don’t work:

    = keyboard leds (NUMLOCK, CAPSLOCK, SCROLL LOCK
    = power switch led

    I have probebly disconnected something between tehe keyboard assembly and the rest..

    Keyboard illumination is ok. TOuchpad working fine.

    Any ideas of what went wrong?? Thanks


    (during disassembly a small metal part fell off and we cant find where it belongs)

    • IML Tech

      @ Andrei,
      Check cables shown in the step 14. Make sure both cables are seated correctly.

  3. Andrei

    Hi, Thanks for the help!!! double checked these 2 cables. They
    look good to me. Any other suggestions?

    • IML Tech

      @ Andrei,
      Sorry, I cannot give any good advice without looking at the laptop. It feels like loose connection somewhere but I cannot tell where.

    Did you ever find a solution? I am having a similar problem with my vpcsc31fm/s. Acually I had the motherboard repaired by a shop and the system is working again, but no LED’s as you mention and my optical disc does not eject from the button either….but does from the windows eject menu. Would this be a connection missing from the motherboard? Based on what you’re saying, the cables from step 14 are probably connected properly, if not there would probably be a lot more problems.

    I did all the steps to clean the cooling fan. After put it all back together there are few keys (A,W,Q,Z,P,windows key ect) on the keyboard dont work. Can you show me how to fix it?

  6. Stefan

    hi, plz help
    I clean my fan then put back evrything together but now the laptop wont power up/turn on
    its not turning on anymore

  7. Mario

    I sent my laptop to a computer store to clean it up and after that it never sound again, even if a plug a headphone on the headphone socket any idea about what can I double check in order to fix it


  8. Alice

    Mine just suddenly shut down by itself while i was watching a movie. I tried to turn it back on but couldnt and nothing lights up. Then i charged it, but the little ‘charged light’ on the side of the laptop didnt show. Im guessing it was overheated. What should i do?

  9. Gabriel

    Hey, man thanks for the info. But when i assembled my laptop, it wouldn’t turn on/power up! now i have opened it up again and put all back together, but it still won’t turn on! can you help me out? thanks in advance!

  10. IML Tech

    @ Nuy Nguyen,

    After put it all back together there are few keys (A,W,Q,Z,P,windows key ect) on the keyboard dont work.

    Make sure the keyboard cable is plugged correctly. Maybe you accidentally pulled the cable from the connector during the disassembly process.
    It’s likely that reseating the cable will help to fix this problem.

  11. IML Tech

    @ Mario,

    after that it never sound again, even if a plug a headphone on the headphone socket

    Check cables shown in the step 12. It’s possible one of them is not plugged correctly. Try reseating both cables.

  12. IML Tech

    @ Alice,

    Then i charged it, but the little ‘charged light’ on the side of the laptop didnt show.

    It’s possible the laptop will not turn on because the AC adapter failed.
    I would test the adapter with a voltmeter to make sure it outputs correct voltage. If there is no voltage, replace the adapter.

  13. IML Tech

    @ Gabriel, Stephan,

    But when i assembled my laptop, it wouldn’t turn on/power up!

    Probably the laptop will not turn on because it’s not assembled correctly. Most likely it’s related to not properly inserted/connected cables.
    There is no way I can tell what exactly is causing this without looking at the laptop.
    When I have a problem like that, I take it apart again and check ALL cables to make sure they are seated correctly.

    Hey ! Hi ! Thanks a lot for the steps. Was very useful. I tried to dissemble and assemble all the parts back. The first time the power button worked but the keypad and sound system was not working. So I dissembled again to fix the loose connections. But the second time the power button is not working at all. Could you show a close up of only the power button functioning. I know its loose connection but I need to know how to exactly connect the power button alone. PLS HELP !

    Can you also show how to take out the touchpad for VPCSE or VPCSE15FG model ?
    I replaced the whole palm rest but facing little bit of difficulty in taking out the Touchpad..

    Thanks in advance..

    • IML Tech

      @ JD,

      I replaced the whole palm rest but facing little bit of difficulty in taking out the Touchpad.

      Is it glued to the palm rest with adhesive tape? You can try using a hair dryer to soften the adhesive tape. It will make it easier to separate the touchpad from the palm rest. I don’t have a guide for that, sorry.

    hi, I accidentally spilled coke in my bag and I think the liquid go to the front edge of my laptop inside the bag. Then my laptop won’t turned on. Then, I dried it without disassemble the laptop completely (just remove the battery cover and open small part of keyboard top cover). Afterwards, the laptop able to turn on, but now the microphone won’t work and the 2 lids at the front edge somehow won’t turn off (even when the laptop shutted down). Do you know which cable I should fix for it?

    Hi, a couple of days after a thunderstorm very close my vpcsa did not turn on and the batterylight at the front kept on flickering. after removal of the battery the laptop functioned normally.
    i ordered a new battery on the internet and after installing (battery charged 75%) the laptop functioned normally again. exept for the next day it wouldn’t turn on again an same light flinckering. Again I removed battery and laptop functioned normally. Can you give me an idea of what is wrong?

    When you opened this baby up, were you able to tell if the processor were removable? According to CPU boss, the 2450M processor belongs to socket G2 and is removable, but I am skeptical. I might consider upgrading it if it is. Also, my screen is flickering and sometimes going dark until I pivot the screen a bit. I’m guessing its an improperly seated cable, but I rechecked it and they seem OK. Anything else you are aware of that could be causing this issue?

    I have a sony vpcsa dead “no lights” – “battery led is off”
    The Charger has green light on.
    Laptop has only 2,5 years of life 🙁
    I had shut down the laptop because the battery was low.
    The day after I connected the charger but nothing works and battery led was off.
    I tried to do different test:
    Remove battery
    Hold button (start) down for 50 seconds

    do you have any idea to save this laptop?

    Best regards ercole.

    I’ve opened up the laptop to clean the fan a little bit and after I put it back together the power button and the keyboard did not work anymore. Most probbly because the cables are not seated correctly. The problem is that I do not know how to properly tape back the cables. I tried multiple times and once the power button worked and some of the buttons too but I still don’t know how to properly place the tape at the edge of the cables. Can you give me some pointers? Thanks

    my wife has spilled some white coffee over the side of vaio vpc-sa and now the keyboard is not functioning properly (every key pressed the computer goes to sleep; then every key pressed, computer wakes. Keys are working – for example in calculator or notepad it shows pressed sign but goes to sleep)
    Does anyone has any tip, how to remove keyboard from the palmrest (STEP 17)? Is it glued or it has some hidden pins or clips that it is holding it to the palmrest housing (plastic)? I have come this far, but afraid to break something while pulling out the keyboard. If cleaning under water won’t help I’ll buy new keyboard and replace it.
    Best regards, Robert, Slovenia

    Where can you find one of those standard hard drive caddies for this computer? Mine does not have that hard drive caddy and I’d love to find one. Is there a part number on it?

  25. Frankfurter

    Can somebody explain a little how to take down the bezel? It looks quite different from the normal notebook bezel. VPC SA and VPC SE use the similar bezel, I have googled everywhere, but nobody has show a picture or video how to open this Sony series. Thanks a lot for all suggestions.

  26. sash

    I was able to get a replacement keyboard from a used vaio, but i am not able to fix it fully. if anyone has any video please let me know.


  27. Pri

    Thanks a bunch for this! Incredibly helpful, and the trick is to have lots of space to work in and be organised! Was having trouble with the keyboard when I put it back together. Remember to lock the connectors!


  28. Carlos

    Hi All
    Whats the name of the cable on step 14? I might need to purchase it haha… (the white one).

  29. Andrea

    I have a sony vaio vpcsa 2c5e. Today it decided to not turn on. I can hear the hard disk running, but no led are turned on (start button, caps lock, keyboard, screen, etc.) only the light of battery charging is on when connect to ac cable.
    Anyone has idea of the problem?

  30. Tim

    I have a problem similar to andrea, no lights, except for the one for the battery at the front, left side, when ac adapter is plugged. Also, no sound from fan or so, only a slight short noise from the dvd drive, shortly after pressing the power button.
    I tried to remove battery and ac adapter and press the power button for a minute, but no success.. The laptop was playing a video and suddenly power went off. Then it tried to boot for 2 seconds and went dead again. Any ideas?

  31. Kostas

    Finaly, how can we put back the keyboard when unglued from the palmrest?

    Hey i know this is a old post do you have a guide to replace lcd cable ? Thanks

    • IML Tech

      No, I don’t have a dedicated guide explaining how to replace the LCD cable.
      In order to replace the cable you’ll have to:
      1. Remove the top case (shown in step 16).
      2. Separate the display panel from the laptop base (not shown).
      3. Disassemble the display panel (shown after step 19).
      4. Remove the LCD screen (not shown).
      5. Replace the LCD cable.

  34. Mara

    I have a SONY Vaio S VPCSC1AFM, the left mouse button no longer registers when I press it, damaged probably from either overuse or drops. Any idea how I can fix it or replace it?
    Or do I have to replace the entire top case?
