Hardware Preventive Maintenance


Obviously at this point you're at a computer, look, watch, what is for you, What brings you benefits?, Have I given proper use?, Have I care as it should?, Would you have given preventative maintenance needs?, and here you're asking, What is preventive maintenance?


Preventive maintenance is the proper care you give your computer equipment, in advance of other mishaps that may occur over time due to not properly perform this measurement, ranging from software and hardware of a computer, the constant review each of these, taking into account several important points that will implement the hygiene, care for the area where the environment in which you install it, among others.

All these important points to keep influence in optimal condition, prolong their productive life in the system be reliable, caring and files were kept, to keep the programs without alteration, to sail at a reasonable speed and reliable. We bow to the preventive maintenance of hardware, which is the maintenance that is applied to all visible and tangible of the machine as a keyboard, screen, speakers, printer, processor, hard drive, enclosure, power supply, etc..

Which is not very complicated, with a good knowledge of the machine can get to do it yourself and save what you would spend hiring a specialist.

So do not worry! you just have to take into account the following 10 simple really.


1 . The physical location where you install it, careful not to put off the window as the sunshine dust accumulates more quickly, if where there is carpet, it would be important to constantly suck. You must make sure the electrical current that is installed there, which is suitable and stable.

2 .- Located in a cabinet that can be easily cleaned.

3 . Keep it in a place with adequate ventilation in hot weather and take it into an air-conditioning, more so in this city in which we live.

4 . Do not use the monitor as a shelf, people usually put things even get to stick them, generating more heat.

5 . Do not eat or smoke in front of her.

6 . Before use, always wash your hands.

7 . Having regulatory support.

8 . Clean the parts of the computer with a clean and free of dust, lint or other debris that interfere with hygiene, you can also use a liquid soap that does not contain many chemicals.

9 . Turning off the PC and let it cool put some bags that protect both the monitor and the keyboard, there are different forms and even affordable.

10 . Remember that before you install a computer to analyze everything, which satisfies the above (Berry, do a little examination of the scene).



We emphasis on cleanliness, highlighting the following:


For cleansing, first disconnect the power source and peripheral components of the PC. You can use a torch or small species but do not have, you can blow slightly parties. Review the internal components, for this you must know a little about how they connected each card, memory modules, hard disk, and so on. Watching it is in its right place and that are not loose or unstable. It is recommended that you open the wing when downloading your machine prior static electricity, to accommodate the screws so that when the closures will know how each screw.

Cleaning the monitor: It is recommended only if you uncork it will fix something and more complicated, because when you turn off the computer stores a lot of energy that can be harmful, that is why, if you have nothing just blow through the vents, clean the screen a dry cloth.

The Mouse: it is important to clean, opening the bottom, which is very simple, and turning the ball if your case or equally with the Optical Mouse, also watching the pad where you have to have no waste.

For CD-ROM, DVD, etc.: There are special discs for cleaning.

Peripherals: should be cleaned with a cloth with a little liquid soap and then alcohol-free cleaning with a dry cloth.

This maintenance tools:

- Wrist strap: prevents you from an energy charge. You should consider that before you touch any parts inside the PC is necessary to discharge static electricity from your body. This is made of a metal that conducts electricity and is connected to the earth pin physics, costs about $ 60.00 and $ 80.00; Rags dry lint-free brushes, screwdrivers, screwdrivers (to open the machine if necessary), isopropyl alcohol , which is a colorless, flammable alcohol, etc..

There is practical and simple.

Did you know? By doing this continuously depending on how you use it, you're free of many diseases, if so, would not only be saving the integrity of this unit but also your health. In January last year carried out an investigation, which was to make a comparison of the germs on your keyboard and toilet in an office. I think many people are not aware of germs and bacteria that can have your computer, maybe now you are with in using these bacteria. The main cause of these bacteria was in office workers ate up the computer leaving food scraps, crumbs, liquid, soda, coffee, etc.. This, but found the dust and created a call center of infection, causing diseases such as gastroenteritis is an inflammation of the intestine and urinary tract infections.

The day we take responsibility to acquire a computer, we must also take with it the responsibility to care for their life span is longer and meets all our needs adequately (jobs, consulting, video, wireless Internet, etc.).. As a mutual aid. So we start looking at our PC not only as an object of the technology, but also as an object that has its own needs. Turn to her and ask again what was raised earlier in this writing.


Preventive maintenance a habit that we must start from NOW



Take care and take care.

Corrective maintenance of hardware



You've probably heard a lot of corrective maintenance, or at least you have seen the need to replace or repair any part of your machine. This is what we call corrective maintenance.
Did we perform preventive maintenance to your PC?, If you did and your computer already suffered, you'll have to go this maintenance.
In the last entry we talked about the hardware preventive maintenance, corrective maintenance now talk of it, this depends on the other, as if not done properly preventive, corrective emerge, and there will be more difficult and expensive to early resolution.

Corrective maintenance is to remove, replace or operate anything that is not at peak performance, giving your machine problems and difficulty performing tasks. It ranges from a small repair such as welding or adjustment screws. In many cases, a better option is definitely changing the damaged item and replace it again, this long term will be more economical and beneficial as getting a brand new, guaranteed duration, and thus the performance in your machine.
There are 2 types of corrective maintenance are:
The unplanned: it is given without expecting it, comes without warning and requires their prompt resolution, if not, there might be costs, property damage or human adults. This happens most often in units with a more pronounced age, you do not know which and when it will be no failure. But when they arise will have to react quickly to your call for repair, but sometimes maybe you do not have the required tools.

The planned: this in contrast to the other, if programmed with time and know what to do when it occurs, already having on hand the material, tools, and prior knowledge.

This type of maintenance should be present in companies, of course as in any personal computer or workstation, but here there is a curious parenthesis to take more into account. In any business, requires a certain control data, which in no way can be lost, since in many cases these are vital to the integrity of it. It is therefore important to have an exclusive department for these failures corrective skilled in the subject, with extensive knowledge and experience.
Here are some points you will consider:

- Be very clear that we want, what use we give it.
- As some companies still use low-tech machines that is now obsolete but still useful for them, they do not need a super machine, one that meets your needs, such as simple accounting programs, databases, among other basic applications. Therefore must be parts of some components that are compatible with it, because they can then run out today because the technology is advancing rapidly and are pushing them out of the sale.
- Check that all the computers in optimal conditions, and often depends on one another.

- Have a separate budget for these setbacks.
- Have employees who know how to use your unit and hygiene regulations, and restrictions on use and misuse.
- Take points of repairs has been done and that you will, that is keeping track of the time that such failure occurred.
To change memory cards or the following recommendations:
1 .- Before turning off the machine, check that all your applications work properly, check any peripheral that will not fail as a mouse, keyboard, everything is properly before starting to open the machine.
2 .- All inspected, now if we will turn off and unplug all electrical power, and peripherals.
3 .- Remove the screws, noting where they go each to the final battle and cause no confusion, we recommend putting them in labeled jars, use a good screwdriver.
4 .- Remove the lid, if the CPU is "tower", put her down for comfort, and notes how each element is distributed, or the exact item you want to change.
5 .- Then download your energy or if you have an antistatic wrist strap better. Longer protected, now unscrew the card, or remove the memory you want to change, very carefully.

6 .- Now proceed to put a new one, settling into its proper place, without forcing, remember that everything has its side and you have to find the one.
7 .- I start now, you just have to screw everything back in place, close the cabinet, stopping the CPU, connect, power on and verify if installed properly, and Ready!
For the power supply and HDD is the same steps with only the following respective indications:
For power supply: ATX connector off the motherboard, and all cables connected to it, then desatorníllalo cabinet, you remove it carefully, and then change it the same way as plug and disconnect now atorníllalo the cabinet.
Hard Disk: IDE cable is critical to get hard disk information, one end of this wing is connected to the other motherboard and hard drive, then connected and mounted and then fixed with screws to prevent any inconsistencies.
It is important to know some things about your computer, you may not be a great expert on the subject, but if you know the most important and relevant information that may occur with it. Know how to prevent it, how to repair and most importantly how to use it properly, taking each basic type knowledge. The computer is a world of information that you never finish learning with her, so I slowly sailing knowing. Noting that the use almost daily, if not the whole point, you should start to worry in knowing more about it, knowing when to take something that is damaging, when repaired, and so on.

Maintenance = better job = better performance Take care of your computer, watch your work, watch your economy.

Preventive maintenance software.


You've probably heard about how to keep your software in optimal condition for their functioning, defragmentation, antivirus, Reviews, etc.
Preventive maintenance software is an essential step for the proper functioning of our PC. But first we must know which means PREVENTIVE MAINTENANCE OF SOFTWARE. Software maintenance is one of the most common activities in software engineering and process improvement and optimization of software (program review), as well as correction of defects (corrective maintenance).

Preventive maintenance software is made up of different elements, but all of equal importance:

Defragmentation.

What is defragmentation?
Defragmentation is the process by which files fit on a disc so that each remains in a contiguous area and no unused spaces between them. When leaving continuously writing and deleting files on the hard drive, they tend not to get into areas together, so a file can be "broken" into many pieces along the disk, then says the file is "fragmented". By having files scattered around the disk, it becomes inefficient to access.
Copy, move and delete files is inevitable, because the system is constantly writing temporary files. For this reason, we use the defragmentation tool.

Antivirus.






Antivirus born with a simple tool aimed at detecting and removing viruses off computer during the 1980's.
Antiviruses are programs whose function is to detect and eliminate computer viruses and other malicious programs (sometimes called malware).
Viruses, worms, spyware is software that run normally without the consent of the rightful owner and have the resources to implement features, consuming memory and even delete or destroy information.
Basically, a virus scanner compares the code of each file with a database of codes (also known as signatures or vaccines) of known viruses, so it is important to update it periodically to prevent a new virus is not detected.

Antivirus Examples are:

Avira Free Antivirus AntivirPersonal-
Avira AntivirPremium
AOL Active Virus Shield
Avast Professional Edition
Avast Home Edition
AVG Antivirus
Norton


Debugging.
Debugging is to delete all files that you no longer use or do not serve the purpose of cleaning your hard drive for files that do not use.
In short, debug files means free hard disk space, which is often a process that involves patience and organization. However, it is essential if we have an efficient team and streamline our information so that only stay on our team is essential.

Steps to consider

1. Perform regular cleaning of temporary files.
2. Clear the cache of Internet Explorer.
3. Uninstall applications you are not using.
4. Perform regular defragmentation.
5. Put in CD, DVD or any other form of support, personal files with more than two months without being used.


In conclusion, the preventive maintenance software is a vital process as well as the maintenance that we have seen previously (corrective and preventive hardware) for our computer work as they want it. I think all these together will help us aa maintenance optimize the potential of our computer. Delete unnecessary files, but clean and above all speed and safety in our work are great advantages offered by this maintenance.



Take care and beware!
