HP Looks To Improve Power Management Coordination 63
tringtring writes "Computer World reports on an HP Labs researcher who foretells a future in which power management features will be built into the processor, memory, server, software and cooling systems. Coordination will be paramount. 'What happens if you turn all these elements on at the same time?' the principal research scientist at HP Labs asks. 'How do I make sure that the system doesn't explode?' This future is the vision of Parthasarathy Ranganathan, the man behind the "No Power Struggles" project at Hewlett-Packard. Power management systems will have to operate holistically, without one component conflicting with another, Ranganathan says. Ranganathan is just one of many researchers at the tech industry's biggest labs researching on how future data centers will handle increasing demands for processing capability and energy efficiency while simplifying IT."

You made the assumption that I had a 4750Mhz CPU, the same peripherals, the same size battery with the same battery chemistry and that similar peripherals use the same amount of power. You also failed to account for power management systems that are present in current laptops, which did not exist 10 years ago. Yet another thing you failed to account for is the supposed increase in efficiency (and decrease in overall power consumption) claimed by PC manufacturers, especially with regard to laptops. You even forgot to account for the age of the battery; 10 years vs. a week-old warranty replacement of a less-than-nine-month-old battery.
I have a battery with 8x the capacity in a system with less hardware and a supposedly more efficient CPU which is only about 3x faster, components which claim lower power consumption and over all better power management than my 10 year old laptop from the same manufacturer. Why am I seeing 1/3 the battery life of the old system rather than the 3x increase logic and mathematics tell me I should be seeing?
Someone, somewhere, is lying and it's not me.
Oh, and... first post!

I mean a Commodore 64 running GEOS can move a mouse pointer, show icons and have graphical text editing, all on a 1 MHz 64K 8 bit machine. Extrapolating linearly, which I think I am allowed to do, a 33MHz version of a C64 should be easily able to handle higher resolutions, more colors, etc. much much more efficiently and still be competitive as far as basic tasks go. You don't need a dual core 64 bit 2GHz processor to display text or images... yet modern computers still take perceptible time to display a new window, etc... What is the CPU doing? What kind of demented software is this?
