We no longer live in the ‘throw away’ age of discarding products simply because they have developed a small fault or we are after the latest and greatest new model. Protecting our Earth is now a big priority for most people and businesses, therefore we are adapting our lifestyles to do everything we can to help preserve our planet for future generations. Instead of throwing a mputers.com/”>laptop in the bin simply because one of the components has failed or it is no longer considered to be up-to-date, more and more people are turning to recycling or ‘refurbishing’ as an environmentally sound option.

Recycling can be done in a number of ways, selling the laptop for spares, donating it to charities that supply third world countries or by selling it to a refurbishing company such as Eflex Computers Companies such as this will offer you money for old laptops, whether they function or not, and then refurbish them and put them back into the marketplace. The refurbishing process is carried out by professionals and incorporates the following stages.

The laptop is fully wiped of all personal data, programs, software etc and taken to a ‘blank’ state. This not only protects the previous owner from having any information stolen but also ensures the system is totally clean of any viruses or issues that could prevent it functioning properly. The hardware then undergoes rigorous testing to ensure that all of the components are functioning correctly and that they still have a good life left in them. If any of the components aren’t functioning correctly or are identified as only having a short life span left they are replaced with new parts. Fresh versions of all the software including operating system, required drivers, anti-virus programs etc are then re-installed on the laptop effectively returning it to the same state as when it was first sent out of the factory.

Refurbished laptops are generally considered by a lot of people to more reliable then systems bought directly after manufacture. This is due the fact they have been operated for some time and so any issues with faulty hardware have been picked up and resolved.

Refurbished laptops offer a lot of benefits over buying a new model. The instant one you will see is the huge savings you can make on the price. For the sake of some cosmetic marks that wont effect functionality at all you can save up to 50% on high street prices. The second benefit is the huge impact on the environment. New laptops produce a lot of harmful gases and toxins during the manufacturing process that damage our environment. The refurbished option means 1 less new laptop being manufactured and 1 less old laptop sitting on the local tip!

It attacks your computer like the South American army ant. Tiny, harmless looking critters by themselves, in larger numbers they can cover, kill and dissolve a full grown cow in a matter of hours.

Okay, maybe not exactly like that. But, wood shop and machine shop owners are experiencing the devastating effect manufacturing dust can have inside their shop computers. And they are looking for answers.

It doesn’t take much to ruin your day, especially, when metallic dust meets sensitive electronic components. Electricity chooses to travel in the shortest route possible, and little bridges of metal dust make great short cuts. Zap! WRRrrrrrr…

And wood dust makes a great insulating blanket. That’s okay if you’re lost in a big wood bin and freezing to death, but to a hard working computer it can be bad news. Heat sinks and fans attempt to dissipate the heat from within your computer, but a layer of dust can reduce or prevent this transfer of heat. Also, computer fans can malfunction when dust and grime are allowed to build up. Things heat up. Computers die. Data is lost. Business suffers.

Okay, what’s the answer then? How do you protect your computer from dust?

The actions you are willing and able to take to protect your computer equipment from dust depend on a large number of individual circumstances. Regardless of your situation, I recommend you take a three-front defensive position and optimize for each of the following areas:

• Computer room environment
• Protective computer dust barriers
• Computer maintenance

Let’s look at each of these areas individually.

Computer Room Environment
Control the environmental conditions surrounding your computers. The ideal solution would be to keep your computers and monitors in a clean, climate controlled computer room. In other words, take them out of the danger area. Of course, this is unrealistic or undesirable to many shop owners, who want, or need the computers to operate in the immediate work area.

So what then? Do what you can to control the dust and air pollutants in the shop. Use and maintain dust collectors for woodworking machines and a ventilation system for the shop area. And, if you can’t move the computers out of the shop, try to move them across the room, away from welding, grinding or direct contact with billowing sander dust.

Protective Computer Dust Barriers
These include computer dust covers, dust filters, computer dust bags, and computer enclosures. Each has its advantages and limitations as described below. Determine which option is the best solution for you.

Standard computer covers are made by a number of manufacturers. Usually plastic or vinyl, they are cheap, but effective in keeping dust off your computers and monitors. However, they may only be used while your computer equipment is shut down. And, you must remember to put them on. Every day. In other words, they are almost useless in a busy shop.

Computer filters, on the other hand may be used while the computer is running. Also very cheap, these small pieces of loose mesh material are placed over fan air intakes in the computer case to remove dust from incoming air. Some have experimented with using panty hose, Brillo® Pads and other household items with some success. The main drawback with computer filters is their small surface area. They clog up quickly in dusty areas and must be cleaned, or changed frequently to allow the unimpeded flow of cool air into the computer case. Another drawback is that they leave other openings in the computer case unprotected, allowing fine dust to infiltrate the CD ROM drives, floppy drives and other small openings.

Relatively new on the scene, computer dust bags are a combination computer cover and computer filter. Designed for the harsh, dusty and smoky conditions inherent to wood shops and machine shops, these innovative covers entirely encase the computer processor or monitor at all times, allowing the entire surface of the bag to act as a huge dust filter to remove dust from incoming air. Monitor dust bags have a see-through, anti-static front to allow a clear screen view, and are very effective in keeping dust, wood chips and other debris out of the cooling vents. At around $20 or less, the recommended life-span of the computer dust bag is 3-12 months, depending on the level of dust in the shop. A possible drawback to using the computer dust bag is reduced access to CD and floppy drives. However, it is possible to use these drives if you cut a hole in the dust bag and cover it with a door flap, which is included with the bag. You may also have to cut an access slot to use your USB ports.

Finally, computer enclosures are typically metal or wood, box-like cabinets which your computer processor and monitor are placed in to protect them from the surrounding environment. A variety of fan and filter combinations introduce fresh air into the enclosure. Computer enclosures have the added advantage of protecting your equipment from blunt force trauma, such as a falling 2×4, chemical splashes and other things harmful to your computer. Filters must be changed regularly. Disadvantages include high price, greater amount of space required, and filter maintenance.

Computer Maintenance
Finally, the third part of a sound computer dust protection strategy is computer maintenance. Yes, that means cleaning. Does that scare you? It’s easier than you think. You don’t have to buy all kinds of expensive tools and cleaning agents, and no heavy scrubbing or complicated disassembly is needed. The most important thing is to maintain a regular computer cleaning schedule. It may be as simple as opening the computer case once every three months to blow out the dust. Educate yourself on the computer cleaning basics and decide the right course of action for yourself.

Just as numerous insects and animals perish when attacked by the army ant, a great number of computers are killed by dust every day. Don’t let it happen to you. Follow the common sense ideas shown here and stop computer-killing dust in its tracks!
