Sometimes updating does help, but I would recommend against it unless you have an actual reason, such as random reboots, or update on ram or CPUs supported, etc.
Make sure that you don't update it in middle of weather events too. If it powers down in middle of update, you will have to either send for replacement or order bios chips.
My friend once used wrong model bios and updated his motherboard. He had to wait 3 weeks for new bios chips in order to make his computer work.
In short, Be seriously careful!!
