ADVERTISEMENTS

Sonar Power Manager is a power saving application for your laptop computer that uses a new user presence detection technique to shut off the computer display when you are not present. Sonar Power Manager is intelligent enough to determine whether there is a user sitting in front of the computer, and it will shut off the computer display when you are not present.

Sonar Power Manger uses ultrasonics (sound above 20kHz in frequency and which humans cannot hear) on your computer’s regular sound system. It works with many laptops, but not all. Some users will find that their speakers produce annoying lower-frequency harmonics or noise while the sonar is operating.

Sonar Power Manager works on Windows 2000, Windows XP, Windows Vista, Windows 7 and also on Linux. However, to use it on Linux you must compile from source. Hardware requirements include speakers and a microphone these are built into most modern laptop computers.

It is a very intelligent presence detection system to replace the typical timeout-based display power management on laptop computers. You can download the latest version of Sonar Power Manager from here.
