Problem Possible Cause Solution
HP Display LiteSaver doesn't turn off
the monitor screen.
The Activity Extension time
has not elapsed.
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.
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.
Confirm that the HP Display LiteSaver is compatible
with the system.
1. Right-click on the HP Display LiteSaver icon in
the 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.
The monitor is off but it did not seem to
enter into a low-power sleep mode.
The monitor's power saving
control is disabled.
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.
OSD Lockout is displayed. The monitor's OSD Lockout
function is enabled.
Press and hold the Menu button for 10 seconds to
disable the OSD Lockout function.
Power Button Lockout is displayed. The monitor's Power Button
Lockout function is enabled.
Press and hold the power button for 10 seconds to
unlock the power button function.
