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.

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.
