Power Manager is a utility for automatic shutdown of the computer by timer. The program is able to automatically shut down, reboot the computer, put it to sleep, and display certain messages by timer. It is enough to specify the required time to the program - and as soon as the time comes, it will switch off the computer by itself.
The main benefit of using Power Manager is that it provides automatic, timed control over your computer's power state, saving energy and prolonging device lifespan.
