## Hardware

### Microphone

To activate the microphone with `alsamixer`, open `alsamixer` and press `Tab`. Now activate Capture by pressing `Space`. If it does not work, play around with the other settings.

## Power Management

I suggest you read Gentoo Power Management Guide for great information.

### Suspend and Resume

Suspend and resume works 100% with the default kernel.

Hibernation doesn't work, all it does is shut down the computer.

### CPU Frequency Scaling

See the main CPU frequency scaling article.

### ACPI

To turnoff the computer when you press the power button, put the following in /etc/acpi/handler.sh

    button/power)
           case "$2" in
               PBTN)
                       logger "PowerButton pressed: $2"
                       halt
               ;;
               *)    logger "ACPI action undefined: $2" ;;
           esac

Replace the "halt" line with the shutdown command of your choice.

To turn off the backlight of an ATI Radeon Mobility card, put the following in /etc/acpi/handler.sh

    button/lid)
           case "$2" in
               LID)
                   logger "ACPI button/lid action"
                   STATE=`radeontool light`
                   case "$STATE" in
                       "The radeon backlight looks on") radeontool light off ;;
                       "The radeon backlight looks off") radeontool light on ;;
                   esac
                   ;;
           esac
           ;;

This requires that you have the radeontool package installed (it is in AUR). You also need to add "acpid" to the DAEMONS array in /etc/rc.conf.
