Optimizing Energy Efficiency in End-User Devices

As a high-tech organization, there are many reasons to address power efficiency in your computing hardware, including:

Environmental efficiency initiatives often encompass multiple facets of a business, including how employees commute and alternative power sources. But the hardware your users depend on to do their jobs every day can also play a part.

8 Tips to Reduce Your Computing Hardware Energy Footprint

  1. Consider deploying laptops instead of desktops where possible. Desktops are larger, have more components and require at least one monitor, all of which equates to costing about 3X more to run than laptops.
  2. Replace any CRT or LCD monitors with LED monitors. LEDs consume less power. Older LCDs use cold cathode fluorescent (CCFL) backlighting which can be up to 30% less power efficient than LED.
  3. Prioritize high-efficiency power supply units (PSUs) in desktops or workstations. 80 PLUS-certified PSUs waste 20% or less electric energy as heat.
  4. Utilize Windows 10 Pro energy management. By default, Windows 10 Pro PCs should be sending PCs to sleep after a set amount of time. Do not use screensavers as they keep monitors active and consuming power.
  5. Buy monitors or AIOs that are ENERGY STAR-certified. This certification designates monitors such as ThinkVision and ThinkCentre AIO to be on average, 25% more energy efficient than those without certification
  6. Consider solid-state drives for storage on laptops or desktops. Because SSDs don’t have to spin up a hard disk from standstill they don’t waste energy as friction or noise. This equates to energy cost savings on desktops and longer battery life on laptops.
  7. Regularly scan PCs for malware, junkware and bloatware. These unnecessary apps may be running in the background, consuming energy and disabling sleep mode.
  8. Finally, is it more efficient to turn off a PC vs putting it into sleep mode? Any devices manufactured in the last 6-8 years will draw minimal power in sleep mode, so it makes little difference whether you completely power down or not. The key is to ensure devices enter sleep mode when not being used, and are not woken inadvertently by software running in the background when left unattended.
Optimizing Energy Efficiency in End-User Devices

Of all the energy-consuming devices in the workplace, computers are often guilty of using the most electricity... By switching to sleep mode wherever possible, you’ll limit the amount of power the computer requires.


  • We have a range of workstations with 80 PLUS Gold and Platinum power supply ratings, ensuring advanced users like designers, engineers and programmers have the performance they need, while improving power efficiency.
  • ENERGY STAR® certified ThinkVision monitors and ThinkCentre AIO models are, on average, 25% more energy efficient than those without the certification.
  • Consider Lenovo devices that use solid-state drives (SSDs) for storage. SSDs help cut energy costs on desktops and provide longer battery life on laptops.
