Usually is is said that if you are not having any problems do not update your bios. When I'm running windows everything is fine. But for Linux I think the DSDT is broken.
According to this this updating your bios should be preferred before messing with DSDT.
This is the link for a bios update for my laptop but details section says that it fixes some 'start-up' problem. So, should I use this update or not?
