While Brian is correct (to the best of my knowledge), there may be other strong reasons to install firmware updates. For example, my Lenovo laptop has Intel Management Engine firmware installed. As I recall, there have been security issues with it in the past which could be remotely exploited.

I haven’t set up the Intel Management Engine, but it is interesting in that it allows someone to access the machine remotely even when there is no working operating system. It’s ideal for technical support, but also comes with potential security risks, as does similar firmware from other vendors.
