They are too cheap or poor to continue hosting old drivers and BIOS on their servers. Unlike virtually every other computer manufacturer. It appears Sony dumped every driver and BIOS from their servers for older computers recently. It's not a Windows problem, it can't be fixed from within the operating system. So I'd like to find out if this model ever received another BIOS update, as it's a decent enough machine, handles Windows 10 fine, but the battery life sucks, and it's refused to work with every replacement battery I've tried, aside from a used original official battery, which isn't much of an improvement on the the one that's in it.Īlternatively, if anyone knows of a way to patch or mod the BIOS to make it accept a third party battery, I'm willing to try that. They later released BIOS updates for some of them that removed this limitation, allowing third party batteries to be installed. The current BIOS is R1120Y4, and I'd like to know if another BIOS revision was ever released after this one.īasically, Sony released a bunch of laptops which would detect if you tried to replace the battery with a third party replacement. I'm fixing up an old Sony Vaio VGN-NW20EF/S. If the BIOS update process is interrupted, it could result in turning the laptop into a glorified paper weight.Edit: Wrong forum, sorry. Relying on battery power during a BIOS update could mean running out of juice mid-update. Even though the Vaio laptop is portable, make sure it is plugged in. The Sony statement also suggests “If you have any questions or need additional assistance with the firmware update installation, call Sony technical support at (866) 496-7669 for assistance.”Ī BIOS update is not a complex task per se, but it can be daunting for less technical users. Sony is directing users with affected Vaio laptops to apply the update to prevent overheating issues.
To resolve the problem, Sony has developed a firmware update for the BIOS. While there are no reports of fires or burns caused by the overheating issue, Sony warns that it is a possibility. Sony has received nearly 40 reported cases of Vaio laptops overheating to the point that the casing becomes deformed.
The BIOS for the Vaio laptops was developed by a third party, and customized for Sony by a separate third party, but Sony tested it on the Vaio platform prior to making it available. The heat management system in the BIOS of affected Vaio laptops is not functioning properly and can cause the system to run hot.
