These were forgotten during the initial conversion, probably because most of them consisted only of a single entry. Fix that.

|
|
|
|
<para>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.</para>
|
|
|
|
<para><command>systemd-battery-check</command> 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.</para>

code otherwise.

<para>Takes a boolean. If specified with false, <command>systemd-battery-check</command> command

will return immediately with exit status 0 without checking battery capacity and AC power

existence, and the service <filename>systemd-battery-check.service</filename> 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.</para>
