SYSTEMD-BATTERY-CHECK.SERVICE(8)			 systemd-battery-check

NAME
       systemd-battery-check.service, systemd-battery-check - Check battery
       level whether there's enough charge, and power off if not

SYNOPSIS
       systemd-battery-check.service

       /usr/lib/systemd/systemd-battery-check [OPTIONS...]

DESCRIPTION
       This service checks the presence of an external power supply and the
       battery level during the early boot stage to determine whether there is
       sufficient power to carry on with the booting process.

       systemd-battery-check returns success if the device is connected to an
       AC power source or if the battery charge is greater than 5%. It returns
       failure otherwise.

OPTIONS
       The following options are understood by systemd-battery-check:

       -h, --help
	   Print a short help text and exit.

       --version
	   Print a short version string and exit.

EXIT STATUS
       On success (running on AC power or battery capacity greater than 5%), 0
       is returned, a non-zero failure code otherwise.

KERNEL COMMAND LINE
       The following variables are understood:

       systemd.battery_check=BOOL
	   Takes a boolean. If specified with false, systemd-battery-check
	   command will return immediately with exit status 0 without checking
	   battery capacity and AC power existence, and the service
	   systemd-battery-check.service will succeed. This may be useful when
	   the command wrongly detects and reports battery capacity percentage
	   or AC power existence, or when you want to boot the system
	   forcibly.

	   Added in version 254.
