Understanding power management
Power management is invoked when the computer recognizes that you have not
used 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.
