Sony VAIO VGN-S3HP ACPId power management script

Here’s a /etc/acpi/default.sh script for Gentoo (should work on other distros though) that handles some power management features of Sony VAIO VGN-series. It handles dimming the screen, switching cpufreq to powersave governor and turning on WiFi powersave on AC Adapter plug-out, and restoring previous settings on plug-in back. It also handles manual screen dimming (via Fn-F5 and Fn-F6) with XOSD feedback and hibernating via Fn-F12 key.

You need the following packages installed:

• sys-power/acpid
• sys-power/cpufrequtils
• media-video/nvclock
• x11-libs/xosd
• sys-power/hibernate-script
• net-wireless/wireless-tools

You may need to tweak the DISPLAY variable. The Power Button and Lid events are handled via GNOME Power Manager, thus handling via acpid is commented out.
