Disable peripherals & ports for better battery life?

Archived from groups: comp.sys.laptops (More info?)

When I got my IBM TP600E a few years back, somebody suggested that
disabling (in device manager or the IBM config utility) the ports &
peripherals I wasn't using would get me better battery life. Since it
didn't cost me anything, I've done that for as long as I've had it.

Was there any truth to that? Would I see any benefit from continuing
this practice with my new R51?

Does the spiffy power-management scheme in Intel's "Centrino" chipset
extend to the peripherals, or is it confined to the CPU?
