Windows Vista delivers some pretty snazzy new graphics, but all that "wow" can be a real drain.
With the new version of Windows, Microsoft has created an operating system that offers advances in many areas, but laptop battery life is not one of them. Going by internal tests at one hardware maker, which declined to be named, there is noticeably lower battery life when Vista runs in its "average power" mode.
Microsoft has said that the current versions of the update deliver less battery life than Windows XP, but the company has also said it hopes to close the gap in the coming months.
One of Vista's most visible changes is its Aero interface, which offers spiffier graphics when people navigate through the operating system. Its advanced Aero Glass effects include translucent windows and animated transitions, as well as the ability to move between windows and documents by selecting from miniature versions of those items.
