NAME

7       level whether there's enough charge, and power off if not.

SYNOPSIS

10       systemd-battery-check.service
11
12       /usr/lib/systemd/systemd-battery-check [OPTIONS...]
13

DESCRIPTION

15       systemd-battery-check.service is used to check the battery level during
16       the early boot stage to determine whether there's sufficient battery
17       power to carry on with the booting process.
18
19       systemd-battery-check returns success if the device is connected to an
20       AC power source or if the battery charge is greater than 5%. It returns
21       failure otherwise.
22

OPTIONS

24       The following options are understood by systemd-battery-check:
25
26       -h, --help
27           Print a short help text and exit.
28
29       --version
30           Print a short version string and exit.
31

EXIT STATUS

33       On success (running on AC power or battery capacity greater than 5%), 0
34       is returned, a non-zero failure code otherwise.
35

KERNEL COMMAND LINE

37       The following variables are understood:
38
39       systemd.battery-check=BOOL
40           Takes a boolean. If specified with false, systemd-battery-check
41           command will return immediately with exit status 0 without checking
42           battery capacity and AC power existence, and the service
43           systemd-battery-check.service will succeed. This may be useful when
44           the command wrongly detects and reports battery capacity percentage
45           or AC power existence, or when you want to boot the system
46           forcibly.
