Organisations that are actively employing PC power management functionality can expect to save $43,300 (£29,192) per year, compared with an unmanaged 2,500 PC organisation, says analyst firm Gartner.

In addition, says the analyst, turning off and unplugging machines saves a further $6,500, but this may affect employee productivity because updates will need to be carried out during working hours.
"Much attention on power consumption has focused on the datacentre, but PC power consumption in an organisation can also be significant, especially given steadily rising electricity prices," said Gartner analyst Federica Troni.
"IT organisations should recognise that the greatest savings come from employing power management features. They should investigate the power management capabilities of their PC lifecycle management tools, and PC power management point solutions to implement these policies and to better support management activities," she said.
