Question about Sony VAIO Notebook

1 Answer

The fan of my Sony Vaio VGN-CS36GJ laptop has been making a loud buzzing sound for the past 2 and a half months; it almost sounds like a truck. The sound is not constant, but intermittent - it comes up about every 5 seconds, regardless of what I am doing on the laptop. There is no overheating. Your help in how to resolve this is much appreciated.

You'd better open up the laptop and do a thorough cleanup, and do the cleanup each 3 months. While you're at it, get a lubricant for cleaning up and degreasing electronic contacts and spray a bit of it in the electric motor of the fan. These cans are cheap and you can probably find it in your local supermarket or electronic repair shop.
This buzzing noise may be caused by a dust clog, or a dried out spindle axis. The thorough cleanup and lubrication will help. I've done this countless times on many laptop models. The other option is buying a new fan, which can sometimes cost up to $50, so better do the cleanup. Its free :)

My laptop (sony vaio VGN-CS325J) fan makes a horrible noise


Hi kufreudokang,

The VGN-CS1xx, VGN-CS2xx, VGN-CS3xx computer models have a known issue that the cooling fan in the Computer may make continuous scraping, whirring, chriping and/or clicking noise while running. As a part of Sony's commitment to quality, Sony provides a free repair for an additional 36 months beyond the standard limited 12 month warranty (48 months total) for fan replacement.

As you're experiencing the issue, you can contact Sony Support at 1-888-476-6972 to set up a repair service at our Sony repair facility.
Hope this helps.

Please post back if you require further assistance.

Thanks for using FixYa.

Sony Vaio fan making noise


Hi:
Not sure of a user cause for the fan to run full speed, unless you are using the laptop in a high heat environment, or setting it on a bed or other area where it is not getting adequet cooling air. If it does it right away, when you turn it on , cold, then there might be a laptop hardware problem. If you leave your laptop on all the time, then you might be inducing the problem. I had a HP high performance laptop, that the fans would not turn on at all till it ran an hour or so, then they would stay on loud for 10 or 15 minutes, then shut off, then cycle.

Laptop Freezing Problem


To be honest this still sounds like a fan problem. The freeze will happen if the laptop overheats. Maybe you should have it repaired again by a different company.(ask for the fan to be replaced!)

Annoying noise from inside my Vaio


I had the same problem with my Vaio, and I called in Sony Support and they called in a technician who came to my house in 2 days! Apparantly Sony got a batch of defective fans and if you are still under warranty they will replace it for free. Good luck!
