time has not elapsed. The default Activity
Extension value is set to 10

passed, before the monitor

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.
