Understanding power management
Power management is invoked when the computer recognizes that you do not
use your mouse or keyboard for a user-definable period. There are several states
as described in the table below.
For optimal performance, unplug the USB cable to switch off your monitor at the end
of each working day, or whenever you expect to leave it unused for long periods during
the day.

●
Use solvents or abrasives.
●
Use flammable cleaning materials to clean your monitor or any other electrical
●
equipment.
Touch the screen area of your monitor with sharp or abrasive items. This type of
●
contact may cause permanent damage to your screen.

may harm the coating of the screen area.
