Over the last few weeks, Microsoft has been researching reports that state that Windows 7 has been ruining batteries. Well, two days ago, they came out with an update stating that Windows 7 is not ruining the batteries, this is all part of the plan.
If you want a heafty read, look over this long post by Microsoft on their blog. It basically states that Windows 7 uses internal reporting in the batteries to determine when your battery has started going downhill. They set this alert up when 60% of the battery has effectively failed. This means that when you charge your battery, you only get 40% of the original charge, even though the battery says it’s 100% charged. This situation ends up with a 100% charged battery lasting only 45 minutes when it use to last almost 3 hours when it was new.
So, it’s not Windows, but your battery that you need to consider replacing. Most batteries retail for approximately $99. This is one reason I buy an extra battery every time I purchase a new laptop.
