Bios Mods -The Best BIOS Update and Modification Source

I ask for your help to change the bios of a laptop brand sony vgn-cr360f model, also known as PCG-5K1P. Specifically I want to ask us if they can modify it so that the shutdown temperature from 45 degrees to 95 degrees or more, as currently suddenly off at forty-five. Bios file is in: R2101Q0

Thanks in advance...
