BATTMOND(1) General Commands Manual BATTMOND(1) NAME battmond -- monitor battery level on ACPI-enabled (laptop) computers SYNOPSIS battmond [-d device] [-i interval] [-W warning] [-H halt] [-z] [-h] DESCRIPTION battmond monitors the battery level on your ACPI-enabled (laptop) com- puter. Battmond probes your battery level in predefined intervals. When the battery level is running low it writes a warning message to the syslog. On critical level, it powers the computer down. Both lev- els and the probe interval can be configured on the command line. battmond probes the battery level through the ACPIIO_BATT_GET_BATTINFO ioctl(2) on /dev/acpi. -d option allows for defining a different de- vice, although you shouldn't (probably) need it. Probes are performed in regular intervals of 10 seconds. This value can be tweaked through the -i option. When the computer is on battery (i.e. there is a battery present and no power cord is connected), battmond checks the battery level against two values: the warning and the halt threshold. If the battery level goes below the former, a warning is sent to the syslog with a priority of LOG_ALERT. If it goes below the latter, battmond initiates a system shutdown, through a call to /sbin/halt. The warning and halt thresholds can be tuned using the -W and -H options respec- tively. Values are expressed in percentage of maximum charge, with de- fault values being 10 (%) for the warning message and 5 (%) for the system halt. Using the -z option will switch the behaviour of the pro- gram to suspend the computer instead of shutting it down. Finally, -h prints a brief help message to the stderr and terminates the program.
