Since the introduction of the world’s first green PC in 1993, Fujitsu Siemens Computers has been recognised as a leader in environmentally sound professional products such as FUTRO thin clients and ESPRIMO professional PCs. The company has, over the years, introduced power savings features such as switched monitor outlets, which can save up to 50 percent in display power consumption; low power soft off, which yields a 30 percent savings in power consumption in stand-by mode; the eco button, which extends battery life by powering down energy consumption of components and the brightness of the display; and Power Management technology which can reduce energy consumption by 15 percent. Overall, the company is striving to dramatically reduce energy consumption when products are in On, Sleep, Stand-by, and Off power modes.
Great lengths are also taken to source energy efficient components from suppliers, as mandated in Guideline FSC03230. The use of high performance processors such as Intel®Core™2Duo and AMD Athlon X2 together with Fujitsu Siemens Computers technology has enabled the company to cut the energy consumption of its professional PCs and notebooks in half in the past year.
Presently, 52 percent of all of Fujitsu Siemens Computers’ PC products are green. Fujitsu Siemens Computers’ focuses on the energy saving features and technologies of the ESPRIMO range introduced in 2005. The ESPRIMO P5615 and E5615, for example, require 23 percent less power than comparably configured computers. In tests to assess the energy consumption of the ESPRIMO, it was calculated that 1,000 devices would save €9,792 worth of energy – which over three years would amount to savings of €30,000. Additional savings can be made through the use of Fujitsu Siemens Computers’ switched monitor outlet. By using this accessory, 1.000 PC can save an additional € 7000 per year. This means that choosing an ESPRIMO E series with a switched monitor outlet could save an organisation with 1,000 PCs €65,000 over three years*.
Research has shown that 50 percent of the world’s PC users never adjust the power management settings of their PCs for fear that it will impede performance. Unfortunately for them, studies conducted by Fujitsu Siemens Computers have revealed that by simply optimising the power management settings one can reduce power consumption by 15 percent on a PC with no loss of performance or comfort. Not only do Fujitsu Siemens Computers’ PCs incorporate adjustable settings which regulate the use of energy, but the company also provides technology such as the now2-Client software which manages energy settings across an entire network and reactivates the settings as users log on. Other software solutions such as DeskView provide administrators with the capability to easily and centrally control power management settings.

Top five tips for energy savings (professional desktop) |
- Turn off your PC and your PC monitor at the end of the day
- Adjust your PC’s power management settings to save energy. This is easy to do:
- Right click on your mouse
- Select ‘Properties’ then ‘Screen saver’. Select ‘Monitor power’ and then ’Power’
- Alter your settings. The recommended settings for lowest energy consumption are:
|
| 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 |
- Before buying a PC, think about how much graphic, memory and expandability you realistically need. Sometimes it is this unnecessary performance which uses the most energy
- Seek advice from the experts. The European Commission offers detailed information about the ENERGY STAR eco-label as well as the power consumption of current office computers at www.eu-energystar.org
- Don’t be afraid to ask your retailer about which PCs are the most energy efficient. They will be able to recommend a variety of models for you to consider.

Our professional Notebook range is equally well equipped to save energy. The extension of battery run time has been a focus for years and has led automatically to lower energy consumption. All LIFEBOOK professional notebooks carry an EcoButton which automatically extends battery life by powering down energy consumption of key components and the brightness of the display. The LIFEBOOK C1410 and LIFEBOOK S7110 are the first and only notebooks to have been awarded the Nordic Swan certificate through their low energy consumption. Furthermore, the LIFEBOOK P7230 and LIFEBOOK Q series will carry the Energy Star 4.0 certification. All professional mobiles in standby mode consume less than 1 Watt of energy per day.
Displays are also a consumer of energy and should be considered as part of any energy-saving initiatives. CRT monitors were phased out by Fujitsu Siemens Computers in 2006; the latest TFT displays consume only a fraction of the energy needed by these older models - on standby typically less than 1 Watt per day and in operating mode no more than 32 Watts per day. This could save a user up to €4.44 per year per monitor – which might not sound like much but just how many monitors does your organization have running today? All displays qualify for the Energy Star 4.0 Tier 2 certification (with the exception of the 24” model) and our LCD displays are TCO’03 certified. Our Premium and Business LCD monitors also comply with the standards set by the Blue Angel certification.
