cpu_slowdown=1

disk_dwell_time=20

disk_spindown=1

graphics_powerdown=1

graphics_standby_dwell=5

graphics_suspend_dwell=10

graphics_off_dwell=15

For the disk_dwell_time, graphics_standby_dwell,

graphics_suspend_dwell, and graphics_off_dwell attributes, the

speciﬁed values indicate the number of minutes to wait before powering

down the idle hardware. In this case, the power management subsystem

waits 20 minutes before disk spindown, and 5, 10, and 15 minutes before

DPMS standby, suspend, and off modes, respectively. The remaining

attributes, have a value of 1, which indicates that the function is enabled.

After you create and save the stanza ﬁle, enter the following command to

update the /etc/sysconfigtab database:

# sysconfigdb -a -f power_mgr.stanza pwrmgr

See the sysconfigdb(8) reference page for more information.

4.8.3.2 Changing a Running Kernel or X Server

To change the values of attributes in the running kernel, use the

sysconfig −r command. For example:

# sysconfig -r pwrmgr cpu_slowdown=0

You can change more than one attribute at a time, as shown in the

following example:

# sysconfig -r pwrmgr graphics_powerdown=1 graphics_standby_dwell=10

See the sysconfig(8) reference page for more information.

See the dpms switches in the Xdec

(1X) and xset(1X) reference pages for

information about changing Display power management Signalling modes

and values in the X Server.
