The diversity of technology today has resulted to a high demand for specialized information. This computer maintenance and training handbook provide detailed technical information on the computer systems available within the organization. The significance of the handbook is to enlighten and guide both specialized and non-specialized employees to handle computer system with care. This will be instrumental in expanding the lifespan of the systems, as well as, their usability across the organization. The minimal use of non-technical terms is aimed at encouraging usability of the computer maintenance and training handbook.
They are three main environmental concerns that are raised by the use of computer system across the world. The first is the energy consumption of the computer and other peripheral devices that are used together with the computer. The second is the environmental implication of the physical components on disposal. The toxin introduced to the environment because of the disposal of physical components of a computer system, which forms a part of electronic waste, has a significant environmental implication. The third concern is the process of computer manufacture and its implication to the environment.
The consumption of every computer unit is dependent on the technology and the use of the computer. The company has a green procurement policy that seeks at ensuring that the most energy efficient computer s is used across the organization. However, there are several power saving techniques that all computer users ought to learn to contribute to the green efforts of the organization. The significance of reducing the energy consumption per computer unit is to reduce the carbon print of the operations of the organization. Some of the techniques that users can learn to reduce the energy consumption of a computer include, switching off the computer when not in use for a long time, setting the computer to switch to standby when not used for a shorter period as well as using optimal power saving techniques on the computer system.
The management of electronic waste emanating from computer systems has implications to the environment. Some of the computer parts are toxic to the environment. When these physical parts are disposed inappropriately, they pose a danger to the environment. The company policy is to ensure that it complies with the government regulation on the disposal of electronic waste. Computer systems require the use of uninterrupted power supplies. The UPS constitutes of a battery and an inverter. The batteries pose agreed danger to the environment since they are constructed using chemicals that are widely known to be toxic.
Exposure to water
When a computer system is exposed to water or excessive moisture, its lifespan is significantly reduced. Moreover, the operation of the system can be abruptly stopped by exposure to water. Water creates a short circuit in the circuitry of the computer destroying internal components and inhibiting the usability of the computer.
B how to protect your computer from environmental concerns
It is the responsibility of all the employees of the organization to ensure that the three environmental concerns are well catered for across the organization. When it comes to energy consumption of the computers, every employee is required to switch off their computer when leaving their workstation in the evening. Moreover, every planning team should ensure that optimal utilization of the computers is considered at all the retail outlets. The procurement policy should also articulate the significance of procuring computer systems that are efficient to reduce the carbon print of the organization.
To protect the computer from environment conditions such as water and moisture, a cover should be used. Moreover, the computer should be located away from a source of water within the retail outlet. Protecting the computer from solar can be achieved by the position of the system away from windows of in enclosed spaces.
2. Power protection
How to ensure a computer receives appropriate power levels
It is pertinent that a computer receives adequate and power within its ratings. The power the computer receives is determined by the voltage levels of the mains power source connected to the computer. There common variations in the voltage levels in the mains. These variations make it unsafe to connect a computer to the mains directly. The use of surge suppressors is instrumental in ensuring that power the computer receives is within its rating. Computer systems require protection from voltage spikes through voltage suppressors. A surge protector controls and blocks off the high voltage levels from reaching the computer. Maintain the power sources of the computer at a below the threshold of the circuit ensures durability of the computer. The use of an uninterruptible power supply as a source of power for a computer ensures the appropriate power is drawn by the computer. Moreover, a UPS acts as a backup in case of a power failure. Apart from protecting the computer from voltage spikes the UPS shields it from fall of the voltage levels, frequency instability as well as harmonic distortion. The power requirement for the CPU is specified and is different from that of the monitor. As a result, it would be important to ensure that the power ratings are observed. This is only achievable by selecting appropriate UPS.
How to protect the computer from power issues
The computer should be continuously supplied with power. To ensure that the power source is stable appropriate, electrical wiring should be done. Isolated sockets should be used to prevent interruption of power when the socket is used for other devices. The use of a centralized electrical system is also vital to enhance the safety of the use of computers. The power cables serving the computers close to the walls should be protected using nail plates. Line voltage cables should be separated from low voltage cables such as the unshielded twisted pair data cables. All the electrical cables providing power to the computer and the peripheral devices should be organized and bound together using straps.
3. Dust, static and heat issues
The effects of dust, static and heat to computers
Dust particles settle on different parts of computers both internally and externally. A computer is an electromechanical that incorporates many integrated circuits and circuit boards. When dust particles settle on the integrated circuits, they create an insulating effect. This can result to overheating of the IC thus reducing its durability. The effectiveness of the heat sink attached to any IC is based on the ability of the sink to absorb heat from the IC and dissipate. This is inhibited by the insulating effect of a dust layer. Dust on a computer inhibits the movement of mechanical components and peripheral devices.
The interfaces of expansion slots as well as connectors should be maintained dust free since dust compromises the quality of the connection. Dust can make expansion slots and other connecting parts unusable. Statics are detrimental to the performance of integrated circuits. Electrostatic discharge inhibits the normal operation of the computer parts. Static electricity results from an accumulation of electric charge on the surface of an object. When a conductor comes close to the surface that is highly charged a rapid discharge occurs shifting the accumulated charge to the conductor. Electrostatic discharges are known to cause damage to small electronic devices. A computer system constitutes of multiple circuits, which are at the risk of damage if exposed to an electrostatic discharge.
Exposure to heat of computer system reduces their efficiency as well as their durability. There are parts of a computer that will easily deform at high temperatures. The operation of the CPU and many other integrated circuits in the computer is influenced by the temperatures. At high temperatures, the performance of the ICs is inhibited. It is pertinent to note that high temperatures in transistors create thermal fatigue reducing their durability. The optimal humidity…
