VAIO Power Management is a scheme of power management, which has been developed specially for portable VAIO computers, and allows maintaining maximum productivity and saving maximum of electric power. This utility adds the possibility to switch off some components for power saving. VAIO Power Management can switch off FireWire, USB, card drive, optical drive, Ethernet-controller and wireless adapters. Also it can regulate LCD brightness and speed of rotation of the cooler. This is an excellent feature that allows you to adjust the performance level, maintain low fan noise, and ensure the battery will operate longer by changing further settings such as LCD brightness or shutting off the optical drive. This utility works well and doesn’t get in the way. You can even tune the performance/battery settings to meet your needs if you need to. The CPU fan noise can be adjusted with a total of five settings, with Level 1 being absolutely quiet and Level 5 optimized for performance. At the lowest setting, the laptop does appear to run a bit more quiet than usual. Based on the tests with VAIO Power Management, it can be concluded that it’s necessary to use VAIO Power Management, as it can increase laptop battery’s life twice, in some cases.
