Windows Vista, the latest and currently the greatest OS by Microsoft, comes with numerous improvements, which includes better Power Management.
Power Management is claimed to be better with the introduction of the Sleep mode, and ther tweaks which includes timing to turn off the hard disk, show the screensaver etc. But what does HP says about it?
“It’s a little scary,” said John Wozniak, a distinguished technologist in HP’s notebook engineering department, referring to the work HP needed to do on making Windows Vista more suitable for notebooks.
It is all caused by the introduction of Aero glass, which takes more GPU thus more electricity to run it. Due to the high power that Vista needs, HP and other OEMs have started to modify and optimize the power management that comes with Vista to provide users with a longer lasting battery time for laptop users.
However according to Microsoft’s own whitepaper on the study of power consumption of Vista Vs XP,
“Aero graphics have a negligible impact on overall power consumption.
Vista also addresses many of the arguments that have blocked companies from adopting a powermanagement strategy. The Sleep state is now much more reliable, and the user experience is not harmed – the fact computers resume from Sleep in under two seconds is almost the same amount of time that a screen takes to reactivate from Idle mode in Windows XP. Vista also has built-in management tools via Group Policy.”
What? Aero graphics have a negligible impact on overall power consumption? I do agree that the fact that Vista is more superior than XP in Power Management, but due to other reasons like the introduction of Aero, laptop battery life is actually much shorter!
What do you all think? Is your battery life shorter in Vista? If yes, how much shorter compared to XP?
