Vista Appetite Suppressor owners may have noticed that one thing the new operating system doesn’t do is improve efficiency, in fact if anything it uses more power then due to all of the fancy graphics. Well, let me introduce you to a freeware program, called Vista Battery Saver that claims to reduce power consumption by up to 70 percent. It does this by disabling various power-hungry features, like the Aeroglass graphics and it switches back to normal as soon as you return to external power. Such large savings are a bit optimistic but if you’re running low on juice, with no prospect of a top-up charge anytime soon, then every little helps.
