I have needed a BIOS update for my laptop due to an incorrectly
implemented ACPI preventing me from accessing the thinkpad HDAPS. Also,
a BIOS update can be needed to support new CPUs, or to fix a bug in CPU
detection. Finally, I've had to update the BIOS on my desktop to fix a
thermal detection glitch with the hardware monitoring.

Generally, if you're not having problems, the reccomendation is not to
update the bios.
