Power Manager helps you save energy by reducing the running cost of your ThinkPad. You can use power management to reduce the power consumption of a device and maintain and preserve the state of the file system in RAM in the Reset, On, Idle, and Suspend power states.

You can create and schedule sophisticated energy saving events that automate your ThinkPad, and reduce your running costs.

It also provides guidelines and information about managing device power, including device power self-management, adding power management to a device driver, class-qualified device names, and suspend and resume handling.
