acpibat — ACPI
control method battery
acpibat* at acpi?
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).
The acpibat driver first appeared in
OpenBSD 3.8.
The acpibat driver was written by
Marco Peereboom
<marco@openbsd.org>.
Some systems do not propagate battery insertion up to the driver.
