Understanding power management
Power management is invoked when the computer recognizes that you have not using your
mouse or keyboard for a user-definable period. There are several states as described in the table
below.
For optimal performance, 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.

Caring for your monitor
Be sure to turn off the power before you perform any maintenance on the monitor.
Do not:
● Apply water or liquid directly to your monitor.
● 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.
● Use any cleaner which contains an anti-static solution or similar additives. This may harm the coating of the
screen area.
Do:
● Lightly dampen a soft cloth with water and use this to gently wipe the covers and the screen.
● Remove grease or finger marks with a damp cloth and a little mild detergent.
