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).

SEE ALSO
     acpi(4), intro(4), sensorsd(8), sysctl(8)

HISTORY
     The acpibat driver first appeared in OpenBSD 3.8.

AUTHORS
     The acpibat driver was written by Marco Peereboom <marco@openbsd.org>.

BUGS
     Some systems do not propagate battery insertion up to the driver.

     Smart Battery Specification-based batteries are not supported.
