Microsoft Says No Problems With Windows 7 And Batteries

There's been a flurry of reports in the last week suggesting that Windows 7 is erroneously suggesting that batteries need replacing (and a smaller set of users claiming Windows 7 itself has ruined battery capacity). Microsoft's official stance on the issue? Every case it has investigated has been a result of a faulty battery, rather than faulty software.

The ability to interrogate a battery and report on its health is a new feature in Windows 7 (though whether it will work depends on the type of machine you have). It's not surprising that some people react poorly to being told their battery is problematic, especially on a relatively new machine, but Microsoft says on its Windows 7 blog that every case it has investigated has turned up hardware problems rather than a software issue:

Microsoft has received 12 customer service incidents in addition to pulling 8 additional incidents from various forums. To date (for a total of 20 incidents), none of these have shown anything other than degraded batteries.

Windows 7 Battery Notification Messages [Engineering Windows 7]


    I had this message a few weeks back on my EeePC 1000HD. It was reporting that my battery needed replacing, and I was only getting about an hour before I was down to 20% charge.

    One day I didn't have my charger on me and decided to keep working until the computer died. It stuck on 16% charge for about an hour, then after I charged it no more warning and I'm back to more than three hour life.

    I can't testify as to it being a software issue in Windows or the embedded micro-controller in the battery, but my gut feeling is the battery incorrectly reporting charge levels.

      I think it's a software issue in Windows as Ubuntu seems to read battery life (and expectancy) to a more accurate degree.
