Re: What happened to Intel Speed Step?

We've got a bunch of Lats D800, 810, 820, 620, 630 and 420.

Recently a guy asked me how he could conserve battery on a plane and
reviewing the Windows XP power and Quickset controls it seems I can
control when the machine shuts down the video and hard drive but beyond
that it's only the screen brightness. Then I remembered the old Intel
SpeedStep, for controlling the CPU, but I could find nothing on the Dell
support download site.

So the question is, whatever happened to Intel Speedstep, and do we no
longer have a method for throttling back the CPU and other features to
save battery?

Ah, I also just remembered the newer machines also shut down the Ethernet
port on battery - annoying but if it works, great!





My short answer would be that the newer CPUs/systems are designed to consume
substantially less power and produce much less heat which should (in theory,
anyway) reduce if not eliminate the need for SpeedStep in earlier and more
battery-thirsty systems.

*This is a very generalized statement but is particularly true in the case
of P4 desktop chips in mobile systems with larger (15") LCD displays.

There have also probably been at least slight improvements in battery
technologies also in the last 2-3 years.

That's all I got.
