| # Configuration for Laptop Mode Tools |
| # ----------------------------------- |
| # |
| # There is a "system" to the configuration setting names: |
| # CONTROL_something=0/1 Determines whether Laptop Mode Tools controls |
| # something |
| # LM_something=value Value of "something" when laptop mode is active |
| # NOLM_something=value Value of "something" when laptop mode is NOT |
| # active |
| # AC_something=value Value of "something" when the computer is running |
| # on AC power |
| # BATT_something=value Value of "something when the computer is running |
| # on battery power |
| # |
| # There can be combinations of LM_/NOLM_ and AC_/BATT_ prefixes, but the |
| # available prefixes are different for each setting. The available ones are |
| # documented in the manual page, laptop-mode.conf(8). If there is no LM_/ |
| # NOLM_ in a setting name, then the value is used independently of laptop |
| # mode state, and similarly, if there is no AC_/BATT_, then the value is used |
| # independently of power state. |
| # |
| # Some options only work on ACPI systems. They are marked ACPI-ONLY. |
| # |
| # Note that this configuration file is a fragment of shell script: you |
| # can use all the features of the shell scripting language to achieve your |
| # desired configuration. |
| # |
| # |
| # Modules |
| # ------- |
| # |
| # Laptop Mode Tools modules have separate configuration files, that can be |
| # found in /etc/laptop-mode/conf.d. Please look through these configuration |
| # files as well, there are many useful power saving tools in there! |

| ############################################################################### |
| # When to enable laptop mode |
| # -------------------------- |
| # |
| # "Laptop mode" is the mode in which laptop mode tools makes the computer |
| # consume less power. This includes the kernel "laptop_mode" feature, which |
| # allows your hard drives to spin down, as well as various other settings which |
| # can be tweaked by laptop mode tools. You can enable or disable all of these |
| # settings using the CONTROL_... options further down in this config file. |

| # Enable laptop mode when on battery power. |
| # |
| ENABLE_LAPTOP_MODE_ON_BATTERY=1 |

| # |
| ENABLE_LAPTOP_MODE_ON_AC=0 |

| ############################################################################### |
| # When to enable data loss sensitive features |
| # ------------------------------------------- |
| # |
| # When data loss sensitive features are disabled, laptop mode tools acts as if |
| # laptop mode were disabled, for those features only. |
| # |
| # Data loss sensitive features include: |
| # - laptop_mode (i.e., delayed writes) |
| # - hard drive write cache |
| # |
| # All of the options that follow can be set to 0 in order to prevent laptop |
| # mode tools from using them to stop data loss sensitive features. Use this |
| # when you have a battery that reports the wrong information, that confuses |
| # laptop mode tools. |
| # |
| # Disabling data loss sensitive features is ACPI-ONLY, and it only works if |
| # your battery gives off frequent ACPI events to indicate a change in battery |
| # level. |
| # |
| # NOTE: If your battery does NOT give off battery events often enough, you can |
| # enable the battery-level-polling module to make this work. Look at the |
| # file /etc/laptop-mode/conf.d/battery-level-polling.conf for more information. |

| # Controlled hard drives and partitions |
| # ------------------------------------- |
| # |
| # For spinning down your hard drives, laptop mode will remount file systems and |
| # adjust hard drive spindown timeouts. These parameters specify which |
| # devices and partitions are affected by laptop mode. |

| HD="/dev/[hs]d[abcdefgh]" |
| |
| |
| # |
| # The partitions (or mount points) that laptop mode controls. |
| # Separate the values by spaces. Use "auto" to indicate all partitions on drives |

| # also specify mount points, e.g. "/mnt/data". |
| # |
| PARTITIONS="auto /dev/mapper/*" |
| |
| |
| # |
| # If this is enabled, laptop mode tools will assume that SCSI drives are |
| # really SATA drives that only _look_ like SCSI drives, and will use hdparm |
| # to control them. Set this to 0 if you have /dev/sd devices and you want |
