Guardate un po' che ben di dio di novità ci sono nel risparmio energetico di Vista... Un'altra arma in più da sferrare contro gli utenti che si ostinano a rimanere con XP :D :

Windows Vista includes the following changes and enhancements in Processor Power Management (PPM):


Native operating system support for PPM on multiprocessor systems, including systems using processors with multiple logical threads, multiple cores, or multiple physical sockets.
Support for all ACPI 2.0 and 3.0 processor objects.
Operating system coordination of performance state transitions between dependent processors.
Elimination of the processor dynamic throttling policies used in Windows XP and Windows Server 2003.
More flexible use of the available range of processor performance states through system power policy.
The static use of any linear throttle state on systems that are not capable of processor performance states.
Exposure of multiple power policy parameters that original equipment manufacturers (OEMs) may tune to optimize Windows Vista use of PPM features.
In-box drivers for processors from all leading processor manufacturers.
A generic processor driver that allows the use of processor-specific controls for performance state transitions.
An improved C3 entry algorithm, where a failed C3 entry does not cause demotion to C2.
Removal of support for legacy processor performance state interfaces.
Removal of support for legacy mobile processor drivers.

A tal proposito riporto un post del thread su Win7:

Forse non tutti sanno che con windows 7 si può avere un power management Report piuttosto dettagliato.
Ecco come fare:
Andate in *\Windows\System32 e cliccate col tasto destro su cmd.exe e selezionate Run as administrator,
navigate sino alla root utilizzando il comando cd..
scrivete powercfg -energy
Da quel momento e per circa 60 secondi windows verrà analizzato.
Il report verrà poi salvato nel file energy-report.html direttamente nella partizione dove è installato windows
E' pensato per utenti esperti in quanto racchiude diverse indicazioni in tre categorie:
Errors
Warnings
Informations

Un esempio del log in html:
