Overheating and fan issues for Sony vaio laptop

Overheating and fan issues for Sony vaio laptop

You don't indicate what model you have but in April of 2010 Sony issued a warning about loud and continuous noise from the cooling fans in models VGN-CS1xx, VGN-CS2xx, BGN-CS3xx and VGN-BZ5xx. The noise was described as a continuous scraping, whirring, chirping and/or clicking noise while running. This notice recommended that customers have their computers fixed as soon as possible with Sony offering this repair free of charge. It is unlikely that this repair would still be valid for a product that is now 5 years old but it would be worth looking into this.

The problem of overheating could be from a buildup of dust, hair and other material preventing the fan from adequately cooling the internal temperature of the laptop. A fix that you may perform yourself is to download a BIOS firmware update from the Sony website. It is not recommended that you try cleaning the computer yourself but, instead, take it to trusted computer business. Cleaning is usually not too costly.

Sony has had a history of issues surrounding overheating. In 2010, Sony recalled over 500,000 laptops for overheating to the extent of possible burn injuries to users. Another instance of recall was for a faulty battery pack that led to overheating.
