Software utility extends battery life of Windows 7 systems

TuneUp Utilities 2012 conserves battery life by shutting off hardware components and applications that aren't active.

Software developer TuneUp has updated its suite of optimization utilities for 2012. Among two of the notable changes are features intended to extend the battery life of notebook, netbook and tablet computers by shutting off processes that aren't required or in use.

TuneUp Economy Mode and TuneUp Program Deactivator are designed to boost the energy efficiency of Windows 7 systems by up to 30 percent, compared with the built-in energy savings mode in the operating system. The modes allow users to specify the hardware components, applications and devices that should be shut off or switched into hibernation mode in order to save power. The so-called Turbo Mode allows for 70 "performance-sapping tasks" to be disabled simultaneously.

The software is priced at $49.95, if it is downloaded from the company's web site. (It is $39.95 if you actually buy it at retail.) The upgrade version is $29.95.
