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?

My VAIO TR1 has a Power sheme Program that turns off the optical drive
and the Memory stick functionality in addition to the Prozessor,
screen and Harddisk saving modes.
Maybe your Prozessor has less work to do if you turn your Ports off.
