Many Microsoft Windows 7 users have started to notice a decline in their batteries longevity.  At first they were confused thinking it was the BIOS drivers that needed to be upgraded, but then began to notice that others who installed Microsoft Windows 7 had the same problem. 

The problem is not prone to desktops, but laptops and notebooks as well.  Even a brand new battery does not stand a chance with Windows 7 operating system.

There may be a class action suit taking place soon so be on the lookout if you have encountered this problem already.  Be sure to take necessary precautions, like making sure it is not your computer causing the problems.  Take your computer down to your local shop to get it inspected to see what the culprit is.  More than likely, it will be windows 7.
