Edit: Wrong forum, sorry. Please move to laptop technical support
I'm fixing up an old Sony Vaio VGN-NW20EF/S. The current BIOS is R1120Y4, and I'd like to know if another BIOS revision was ever released after this one.
Basically, Sony released a bunch of laptops which would detect if you tried to replace the battery with a third party replacement. They later released BIOS updates for some of them that removed this limitation, allowing third party batteries to be installed. 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.
Alternatively, 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. It's not a Windows problem, it can't be fixed from within the operating system.
Thanks!
