34 Appendix A Troubleshooting
Possible Cause
The Activity Extension time has
not elapsed.
The HP Display LiteSaver may not
be compatible with the computer
system. Some notebook
computers are not compatible and
the monitor power can not be
controlled.
The monitor's power saving
control is disabled.
Solution
The default Activity Extension value is set to 10 minutes.
The HP Display LiteSaver will wait to detect no input or
movement from the keyboard or mouse for 10
consecutive minutes after the Display Off time has
passed, before the monitor enters into low-power mode.
For example, if the Display Off time is set to 5 minutes
from the current time and the Activity Extension is set to
10 minutes, the HP Display LiteSaver will not actually
turn off the display until 10 minutes of inactivity has
elapsed, even though the Display Off time is 5 minutes
from now.
Confirm that the HP Display LiteSaver is compatible with
the system.
1. Right-click on the HP Display LiteSaver
system tray.
2. Select Power Off Display from the menu.
The monitor screen should turn off if the system is
compatible. To turn the monitor back on, wait 5 seconds
and move the mouse.
NOTE If the monitor did not turn off, then the
computer graphics driver is not compatible with
the HP Display LiteSaver software.
Check the monitor's OSD menu setting for power saving
enable/disable controls. The control should be set to
enable to allow the monitor to enter into low-power
modes.
