HP Z400 Maintenance And Service Manual page 25

The Power Management feature enables the workstation to enter a low-power (or "sleep") mode after a
period of inactivity. When used with an external monitor that is ENERGY STAR qualified, this feature
also supports the similar power management features of the external monitor.
To take advantage of this energy savings:
The Power Management feature has been preset to suspend the workstation to a sleep state after
●
30 minutes of inactivity.
The Power Management feature has been preset to suspend the monitor to a sleep state after 15
●
minutes of inactivity.
Both the computer and monitor can be woken from sleep mode through user interaction with any of the
computer input devices (mouse, keyboard, and so on). when configured with Wake On LAN (WOL)
enabled, the workstation can also be woken by a network signal.

If it is necessary to restore the operating system, you must also reset the ENERGY STAR settings (if
applicable) after the restore.
To verify the factory default power settings for your workstation, select Start>Control Panel, and
then double-click Power Options.
NOTE: ENERGY STAR is not supported with the optional 600W power supply.
