Understanding Power Management; Power Management Modes - Lenovo ThinkVision X1 2nd Gen User Manual

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.
