the reason behind it is that the Level of the ACPI hierarchy increases eventually depending upon the period of windows updates done, All windows updates are not responsible for ACPI. But there are even certain starnge scnerios where a user is confused that the system running absolutely fine for a few months and all of a sudden the same settings which were there before and were successfully able to share power settings from BIOS, just stops sharing it.

wharever speed step u are, first of all i gotta tell u that Schaibeez is facing issue with a system rubnning windows 7 and not windows XP, and the ACPI technology which is being reffered here and not DELL specific technology, well let me brush up your rotten mind, ACPI technology was launched in year 1996, where it means Advance Controller power interface, where System BIOS has the ability to share power settings withe the installed OS, but there are scnerios where if the BIOS is not of the same level top share the ACPI settings to the Operating system, may be just because if teh power settings which the Operating system demands are of the higher hierarchy, then a user will face this issue.
