Top 3 Energy Saving Tips

Many organizations tend to underestimate the energy related expenses caused by their hardware, particularly when it comes to the thousands of office workplaces furnished with PCs. The less energy-efficient these devices are, the higher the costs. The ICT industry is working on technology that help companies to reduce their costs, and Fujitsu is playing a leading role. But saving energy is about much more than discussing costs. It is about helping to protect the environment. With little effort, everybody can contribute to the green attitude. Here are some ideas:

1. Switch off your PC and Monitor

At the end of the working day PCs and monitors should be switched off at the main switch or, where appropriate, at the power bar or plug connector. This prevents standby switches from needlessly consuming energy.

2. Adjust your power management settings

By adjusting power management settings in the operating system, you can adapt a computer’s power usage to suit your working rhythm. It is also very important that the monitor deactivates when not in use, particularly since people tend to switch off their computer in the evening, but not the display. The switched monitor outlet from Fujitsu prevents the display from idly guzzling power all night. Indeed, the greatest amount of energy can be conserved by avoiding unproductive operation. 

The power management values for any PC or notebook can also be set manually:

  • Press right mouse button on the screen
  • Select properties tab “screen saver” – chapter “monitor power”
  • Press “Power…”

Recommended settings for lowest energy consumption

Settings for net battery
Screen off 10 min 5 min
HD off 15 min 10 min
Standby 20 min 15 min
Hibernating 1 h 30 min

3. If you are buying a new PC - check the label

If you are going to buy a new PC think Green and check the Eco labeling. The European Commission offers detailed information about the ENERGY STAR® eco-label as well as the power consumption of office computers at The website features an energy calculator for PCs, monitors and imaging equipment at companies and public sector operations, as well as for consumers. It enables a detailed comparative calculation to be made of power consumption and overall costs by allowing for numerous factors. These include purchase price, depreciation periods, and everyday usage scenarios, including specifying power requirements and if an uninterruptible power supply is used. Even the air conditioning system’s effects on electricity requirements are taken into account.
