Interesting stuff, I completely understand this.
But... I haven't been randomly going to user's PCs and checking their CPU speed due to boredom. Regularly,
our users are using heavy duty Excel files, Visual Studio 2010 or sophisticated calculation software, and their
Lenovo laptops are crawling, due to the CPU deciding to run at a slower speed, even when the Power Settings
are set to "Maximum Performance."
The software is crying out for more CPU speed, but the Lenovos are choosing
to run slower.This
is my problem.
It's nothing to do with the software "not being written to make the most out of dual/quad core CPUs",
as soon as you manually change the Power settings, the CPU is fully utilized and the problem goes away
(until the next time the Lenovo chooses to decrease the CPU speed).

This is what is not
happening on many of our Lenovo laptops.
I have MacBook Pro's, Samsung laptops, Dell laptops, Sony laptops, running Lion, Windows 7 and XP,
and none of them
ever have this problem.
This is a bug in the Lenovo hardware/software.

That's a naive response. If I buy a 2.4GHz dual-core laptop, and I'm running CPU-intensive software which
needs as much CPU as possible, the laptop must be able to run at (about) 2.4GHz when it needs to.
Otherwise, why bother buying a fast CPU in the first place ?
Again, I've never seen this issue on any other brands of laptops, apart from the Lenovo ones.
Please, I'm just looking for an answer to one simple question:What do I need to change
on these 2.4GHz Lenovo laptops to make sure that (at Maximum Performance
setting, and when it's plugged into the mains) the CPU will
run at the full speed, when the software
demands it ?
