Home » Blog » IT Guide » Optimal use of IT devices: practical tips for efficient handling
IT devices such as switches, servers and laptops consume a lot of energy, which can be significantly reduced through efficient use and settings. In a globally networked world, an efficient IT infrastructure is essential to optimally manage resources and save energy. Find out how you can expand your infrastructure even further in our blog post “Build an IT infrastructure and benefit from improved processes”.
Choosing the right IT devices
The selection of a suitable IT device begins with a precise analysis of individual requirements. Future-oriented planning is crucial: devices with expandable memory and a long service life offer flexibility for future requirements. Technical specifications such as CPU, RAM and the choice between HDD and SSD are crucial.
IT equipment with lower energy consumption
Modern technologies, such as processors, power supplies, storage solutions and displays, which may offer reduced energy consumption depending on the model
Functions such as screen savers, standby modes and automatic shutdowns
Thin clients with central server resources
Depending on the hardware, usage scenario and server infrastructure, thin clients can consume less electricity at the workstation than traditional desktop PCs
For certain product groups, recognised eco-labels such as the Blue Angel can provide additional guidance. The relevant award criteria vary depending on the product group and may include, amongst other things, requirements relating to energy consumption, reparability or the use of materials.
Hardware andsoftware upgrades can improve the performance of existing systems and extend their service life. It is very important to check compatibility.
Hardware upgrades
More RAM for more efficient multitasking and faster file processing
SSD offers speed benefits and reliability
Powerful GPU for improved graphics performance (gaming, image processing)
Optimization of heat dissipation through stronger power supplies and improved cooling systems
Software upgrades
New operating system versions with security updates and new functions
Regular application software updates for improved functions and security
Importance of driver and firmware updates for optimal hardware performance
Care and maintenance
Regular training increases awareness of the optimal use of devices.
Regular cleaning with microfiber cloths for screens, keyboards and mice as well as dust removal with compressed air for the interior of desktops and laptops. Read more about IT cleaning in our blog post “IT cleaning - its time requirements and aspects to consider”.
Software maintenance with regular updates for operating systems and application software as well as secure data backups in the cloud or on external hard drives.
Security measures such as antivirus software, firewall activation and system maintenance tools to optimize system performance.
Activation of energy-saving settings on devices and consistent switching off of devices outside working hours.
Optimization of servers and UPS:
Determine the size and performance of servers or UPS for your business before purchase
Use power management functions to reduce the energy consumption of unneeded applications and web servers
Reduce maintenance costs by using large servers for the entire company
Blade servers to minimize power consumption and improve energy efficiency
Standby vs. idle mode: In standby mode, the device remains operational but continues to consume energy. In sleep mode, the device's energy consumption is greatly reduced by writing all running programs to the hard disk.
Energy consumption, longer appliance life and recycling
Important measures are:
Efficient energy use: energy consumption and energy costs can be reduced by optimizing device use (energy-efficient settings and switching off unused devices).
Extending the service life: Regular maintenance and appropriate hardware and software upgrades can extend the service life of existing equipment, thereby avoiding the need for premature replacement.
Extended use and reuse: Through repairs, refurbishment and the reuse of second-hand equipment, existing IT hardware can continue to be used. Suitable equipment can therefore remain in service for longer before being replaced or sent for recycling or disposal as intended.
Disposal and recycling: Equipment that is no longer usable should be disposed of properly and sent for appropriate take-back or recycling processes, so that recoverable materials can be reclaimed and hazardous substances can be treated appropriately.
Reduction of greenhouse gas emissions: Lower power consumption reduces energy use whilst the device is in use. In addition, extending the device’s lifespan and ensuring it is recycled properly can help to avoid the need for new purchases and the premature disposal of fully functional hardware.
By selecting equipment to suit their needs, utilising energy-saving features, carrying out regular maintenance and maximising the lifespan of their IT equipment, businesses can reduce their energy consumption and operating costs, and continue to use their existing hardware for longer. Conscious employee behavior and the choice of energy-efficient devices can significantly reduce energy consumption and optimize operating costs in the long term. At the same time, a longer service life can help to avoid the need for unnecessary early replacements.
The efficient use of IT equipment means systematically optimising the entire life cycle of IT hardware in terms of procurement, use, maintenance and disposal. This not only maximises productivity, but also reduces costs by avoiding unnecessary new purchases.
Structured planning begins at the procurement stage, when care should be taken to select equipment with a power consumption appropriate to the intended use. It is also advantageous to record the entire inventory transparently in a central register. This provides an overview of available resources.
Regular maintenance, software updates and data backups ensure security and longevity. Continuous monitoring of device performance also helps to identify problems early on and avoid failures. Conscious behaviour on the part of employees and the choice of energy-efficient devices can significantly reduce energy consumption and optimise operating costs in the long term. IT remarketing makes it possible to professionally refurbish suitable second-hand devices and return them to the cycle of use.
The service life of IT devices can be significantly extended by taking various measures:
Perform hardware upgrades, e.g. expand RAM, use SSD instead of HDD or optimise cooling
Replace individual components instead of buying new ones
Regular software updates and memory cleaning for security and performance
Introduce security measures such as antivirus software, firewall activation and system maintenance tools
Free up storage space by deleting temporary files, downloads and unnecessary programmes
Regularly restart and close background apps for improved performance
Regularly clean devices to protect them from dust and overheating
Conserve battery life, e.g. by keeping the charge level between 20 and 80 per cent
Switch devices off completely instead of leaving them on standby
Use surge protection or UPS to protect against power damage
Dispose of and recycle IT devices properly
IT equipment should be maintained and updated at regular intervals to ensure security, performance and a long service life. Operating system updates such as those for Windows, macOS or server systems should be installed monthly. If critical security updates are available, install them immediately.
Programmes and applications should generally be updated every 1 to 3 months. In addition, a daily or weekly antivirus scan is beneficial. Regular backups are also very important to prevent data loss.
Physical maintenance should not be neglected either. A thorough technical inspection of IT equipment should be carried out at least once a year. Cleaning should take place quarterly to protect against dust and overheating. If the device becomes noticeably slower or applications crash regularly, it is worth checking whether a hardware upgrade or replacement is advisable.
When purchasing new IT equipment, you should first conduct a thorough analysis of the requirements for the new device. Aspects such as expandable memory and a long service life are crucial. The new devices should be as scalable and powerful as possible, while also being energy efficient. The following criteria should be taken into account:
Plan for energy-efficient features
Use modern technologies such as energy-efficient processors or power supplies
Lower power consumption compared to conventional devices
Look for energy labels, certifications or voluntary labels such as the ‘Blue Angel’, as these indicate low energy consumption
Consider ergonomic and stable design
Ensure compatibility with the existing IT infrastructure
