acpibtn — ACPI
button
acpibtn* at acpi?
The acpibtn driver is used to handle the
event triggered when the user presses an ACPI button. Currently, the only
event handled is the press of a power button which causes the system to
perform a regular system shutdown and power off the machine if the
hw.allowpowerdown
sysctl(8) is set to 1.
The acpibtn driver first appeared in
OpenBSD 3.9.
The acpibtn driver was written by
