    Vista draining laptop batteries, patience

    Microsoft's attempt to improve power management in Windows Vista hasn't made
    up for the pretty but power-hungry Aero interface, causing battery life to

    Some of Microsoft's most important customers aren't happy with the battery
    life offered by notebooks running Windows Vista.

    "It's a little scary," said John Wozniak, a distinguished technologist in
    Hewlett-Packard's notebook engineering department, referring to the work HP
    needed to do on making Windows Vista more suitable for notebooks.

    Vista, while touted as having improved power management capabilities that
    would make it easier for users to extend battery life, isn't to some living
    up to that promise. The main culprit appears to be the Aero Glass interface,
    a spiffy new user interface that makes Vista more pleasing to the eye with
    transparent windows and animated transitions when moving from one
    application to another.

    When Aero is turned off, battery life is equal to or better than Windows XP
    systems. But with it turned on, battery life suffers compared with Windows

    Microsoft made some important changes in Vista that do improve some aspects
    of battery life, such as smarter hibernation modes that override
    applications that want to keep running, and simpler options for choosing a
    power management setting. But laptop users who spent extra money on powerful
    laptops to handle the graphics requirements of Vista and the Aero interface
    are forced to run the aesthetic equivalent of Vista Basic, the low-cost
    version of Vista, if they care about battery life.

    HP decided it wasn't going to use the power management settings that shipped
    with Vista, Wozniak said. The company came up with its own set of power
    management settings for Vista laptops, allowing users to select different
    power settings, such as "power saver" or "high performance," that strike a
    balance between processing power and battery life. Lenovo is likewise using
    its own power management technologies honed over several years, said Howard
    Locker, director of new technology at Lenovo.

    "They've really made it complex from a power management standpoint," Wozniak
    said. "The potential is there to do some good things, the bad thing is that
    it comes with the canned settings...and we didn't like any of them."

    Reports that Vista was an energy hog started to surface during beta testing
    last year. At the time, Microsoft said many of the problems would be cleared
    up by the time the operating system launched. Of course, this isn't a new
    issue when it comes to operating system changeovers, said Richard Shim, an
    analyst with IDC. "When you look at a new operating system, battery life
    tends to be worse. When Windows XP came out, that was true, and when Windows
    98 came out, that was true."

    The difference this time around is that notebooks are "the growth engine for
    industry," Shim said. Notebook PCs now account for more than half of all
    retail PC sales and are projected to become the majority for the whole
    market by the end of the decade.

    But battery life problems continue to rankle notebook users. As blogger Rob
    Bushway of Tablet PC site put it, "when a consumer has to
    buy an extended battery to get what they use(d) to get out of a standard
    battery, something is really wrong."

    More than one company other than HP has acknowledged the demand that Vista
    and the Aero interface put on a notebook PC running off its battery.

    "Vista is consuming more power than Windows XP, but we have been very
    focused on introducing more power-efficient technologies," said Bahr Mahony,
    director of product marketing for Advanced Micro Devices' mobile product

    Most attribute that power use to Aero. "In (Aero) mode, you will drain the
    battery faster, but you get something in return because it's cool and nice
    looking," Lenovo's Locker said.

    The Aero interface is automatically disabled when users put their Vista
    notebooks into the "power-saving" profile, one of three new simplified
    power-management states. While that makes for an arguably duller experience,
    Microsoft said it commissioned a study (click here for PDF) that found no
    difference in "responsiveness," or application load time, between a notebook
    with Aero disabled versus one running the fancy graphics: implying that Aero
    doesn't put too much of a load on the system.

    But the notebook and Tablet PC used in Principled Technologies' test had the
    power management setting on "high-performance" when testing Aero's
    performance. At that setting, the notebook won't ever compromise performance
    to preserve battery life, so responsiveness isn't an issue.
    Microsoft isn't deterred by HP's decisions and other criticism. "We actively
    encourage (PC companies) to customize the default power profiles so that
    users get the most out of their hardware," Microsoft said in a statement.

    A more definitive statement on Windows Vista and battery life should surface
    soon, with Intel scheduled to release new chips for notebooks next week at
    the launch event for the next generation of its Centrino technology. Also,
    Bapco, an industry benchmarking organization, is expected to soon release
    the MobileMark 2007 benchmark.

    Microsoft, for its part, will likely have to improve Vista's battery life
    performance over time through the release of service packs and other tweaks,
    Shim said. "The (PC companies) are getting pressure from consumers--who are
    the notebook adopters--who are saying their number one priority on a
    notebook is battery life."

    I averaged around 4 hours under XP. Same machine with Vista lasts around,
    let me see, 4 hours or so.

    Forgot to add, always have the Aero running, even on batteries. No
    noticeable drop in running time.

    So all these people are fools? Or are you perhaps a delusional guy who calls
    himself "Lord"?

    WAIT.. before you start typing your hate-reply on vista, plug the laptop in
    the AC outlet.. We dont want the battery to die on you.. do we?

    Ok.. now tell you have a backpack with car batteries on your back and
    a solar panel cap on?

    You're very angry at software. I have a two-fold suggestion.

    1.) Don't use it.
    2.) Use something else.

    You are angry with people that post.

    1) Watch youtube videos instead of reading newsgroups
    2) Dont go online, grab a dusty book from your bookcase.

    I'll bet your didn't ever bother to really read the article did you (no
    Remember the part about what HP did (or didn't do).
    Remember the part about "high-performance' setting?
    I guess not. Otherwise you wouldn't have bothered to post such a
    mis-leading header.

    Ok.. now tell you have a backpack with car batteries on your back
    Ok .. tell me .. do you believe everything you'd like to believe ;)

    careful now ..

    careful now ..

    I create anything that is not already apparent in physical form and I want
    to see.

    And the first step is to believe anything you want to believe, even if
    everyone else thinks its not worthy, or do not understand, for it is the
    control of thought and belief combined with persistance that gives you
    ultimate power.

    You should study history.. there is only 1 kind of people that do both above
    sentences.. for it is the combination of these 2
    that create remarkable results.

    I am not a person to deceive. My purpose was to get people to read it. You
    did, didn't you?

    Now you have your own opinion about it, and you can disagree with the title
    that I put there solely for an effect.

    What you see as misleading subject line, actually lead you to more
    knowledge, therefore it is leading, not misleading :)

    Opinion...I don't have no stinking opinion about it...I actually have a
    3 yr old laptop running Vista.
    I don't need no stinking opinion!

    must be nice ...
    lets see, I'd call that dreaming

    heh ... a hippie
    remember the easiest person to fool in this world is yourself.

    Look at global warming for your current example of this.

    I do study history ... umm, what kind of people would that be?


    very revealing ;)
