NAME
acpibat —
ACPI control method battery
SYNOPSIS
acpibat* at acpi?
DESCRIPTION
The acpibat driver supports the ACPI
Control Method Battery interface between the battery and the host.
Information about the battery, such as capacity, recharge rate, voltage, and
serial number, is available through this driver. Battery status is updated
through an event triggered when a battery changes state (such as starting to
charge) and, as a failsafe if the system does not support passing such
events, every 10 seconds. Battery status can be monitored using
sysctl(8) or
sensorsd(8).
