Vaiopower is a tool for power management of Sony Vaio laptop devices, and it is intended for all the users who strive to extend their battery life as much as possible. Vaiopower provides a higher level interface to the power management options offered by the sony-laptop kernel module. Additionally, prior to powering a device down, vaiopower makes sure that the device has been deregistered from the system correctly, it unloads all corresponding kernel modules and stops relevant system services. After powering a device back up, vaiopower restores its previous state. Vaiopower can be invoked manually, and it is also run automatically during boot when it disables all devices set by user in /etc/vaiopower.conf.
