    Sony Vaio Laptop / Notebook shutting down suddenly – Fan not working


    Few days back, my Sony Vaio Laptop suddenly started shutting down without any error or warning. It didn’t look like it was a Windows Operating System error. If it had been a Windows error, definitely i would have seen BSOD screen. I was suspecting that it was due to hardware error.

    I tried powering the Laptop and again tried booting it. It ran for few minutes and again it shutdown abruptly without any warning.

    Laptop / Notebook shutdown if the temperature is above certain level.

    I noticed one thing, my Sony Vaio Laptop was heating up and it was hot near the touch pad area. I started suspecting that this is due to the Cooling Fan Problem. I then turned the laptop and checked whether fan is working or not.

    1. I had a similar situation happen to me but it was on my desktop, all of the sudden it kept shutting off during random times. Turns out that the CPU fan had been operating at a slow rate, going on and off and was dying, as a result the computer was overheating. Luckily for me I had a spare CPU fan laying around and replaced it! 😀 It’s a good thing the computers of today auto-shutdown when it senses a heating issue, otherwise we’d have fried computers 😉

      nice share mate
      really helpful to me 🙂 🙂

    3. My trusty old hp is elevated off the desk so it can breathe, and that has helped sort out my shut off issues a lot. You also get thingies you can buy from the computer shoppie that both raises the laptop at a nice angle to work on whilst running a built in fan via USB. This is especially handy for older laptops where the fans are cranky or not working.

      It’s a Sony Vaio, and I’ve had it for about 4 years now. It usually works fine, but recently it’s started shutting down automatically. I’ve tried to make up for it overheating, so I’m not sure if that’s the reason and it’s in the charger so I don’t know if it’s the battery.

      I am facing the exact problem with my Sony Vaio CS110 laptop. Fan needs replacement but Sony CSR is transfering me between the departments. Can you let me know the number to call.

      Its only 16 months old.

      Thanks Nihar. I was able to get hold of sony representative @ 239-245-6499. Technician came to my house and replaced the fan within 2 business days.

    7. I like the pink Vaio. I think selling a pink Vaio is the best thing that Sony has ever made since it started making walkmans. Pink is a color universal to all women, transcending culture, race and religion. No wonder it’s such a best seller among women. – Tanya Bayo
