Some thing interesting you can learn to keep your PC healthy..

I’m sure we have all run our fingers down a surface to check if it needs a clean. That tell tale streak of dust that we remove tell us its time for a little spit and polish. Have you ever wondered what dust actually is? There are those that will tell you that dust is comprised mainly of dead human skin cells, which isn’t a hundred percent true although there is certainly plenty of human skin in the average pile of dust.

Dust particles can vary in size from as large as a few hundred microns to just a few micrometers, the larger particles tend to fall and stick to surfaces whilst the smaller ones tend to remain airborne. Dust particles can contain everything and anything, in various quantities from skin cells, liquids (water or oils), organic materials, minerals, metals and a multitude of chemicals. It all depends on the environment that surrounds us.

In a normal office environment, where dust is usually kept to a minimum (unless it’s your cleaner’s day off), problems associated with dust are usually kept to a minimum. However, in some environments huge quantities of dust can be generated by processes such as sawing, grinding, polishing and cutting.

This amount of dust can have unforeseen consequences. Dust can have serious effects on our health from causing asthma and allergies to more severe bronchial and pulmonary problems. Employees who have to work in dust-filled environments should of course be offered suitable protection, such as dust masks or even re-breathers.

However, have you ever thought what effect dust can have on computers and electrical equipment? Like us, computers need to breath. Dust can block filters and prevent air from flowing through the computer and causing it to overheat. Dust also acts as an insulator which can add to the heat build up.

Dust can also cause a short in circuit boards and integrated circuits causing computers to crash and in some cases- even catch fire!

Dust can also clog up some of the computers moving parts such as the disk drives and even block usb ports and interfaces.

There are thankfully a multitude of ways of eliminating and reducing dust. Protective covers can be used as a temporary but cheap method of refusing dust particles. Alternatively specialist dust-proof computers are manufactured but these are expensive and have to be replaced every time your IT is up-graded.

However, for a more permanent and flexible approach to protecting computer equipment from dust is to use a specialist computer enclosure. These enclosures can house your existing computers, protecting them from dust but with the added advantage of allowing you to replace or upgrade your IT whilst still keeping the same enclosures which can also protect your equipment from fire and impact.

Dust is responsible for millions of hours of IT downtime each year, don’t let it happen to you, protect your computer equipment and you can both breath easily!

Basic Conclusion,

Certain Gateway laptops, as well as other brands, have an infamous reputation for overheating and abruptly shutting down. This can be frustrating and highly problematic, especially if you are in the middle of creating an important document or winning a game. Find out what you can do to solve and prevent this problem.

Laptops come in many shapes, sizes, and styles. Unlike their desktop counterparts, the components of various laptops are far less consistent. This means one laptop uses completely different equipment or technology than the next brand or model, different ways to bundle all those components inside the little cases, and different ways of cooling off. Because of this, certain models tend to overheat more often. If your laptop relies on a fan or drawing air through the case to cool, it will be more prone to overheating.

When your laptop relies on small holes in the case to ventilate and cool off, dust and dirt commonly accumulate in these openings. This will end up blocking your laptop’s airflow, causing it to overheat and shut down. Environmental sources can cause these effects as well. If you expose your laptop to full sunlight for an extended period of time or lock it in your hot car, the heat will affect it. Other causes can be close proximity to a heater or radiator, or simply a dead fan motor.

Clean dust and dirt from your laptop. Start by shutting it down completely, removing any cables and cords, and removing the battery pack. Use dry cotton swabs to clean out slots and small openings. Remove any covers over the fan or other components, and dust with swabs here as well. A can of compressed air with a long, thin, straw-like attachment will help you reach other dusty yet inaccessible areas. Replace the battery and other covers prior to turning your laptop back on.

Specially made notebook pads sit beneath your laptop and safely draw heat away from it. These attachments are inexpensive, with prices ranging from under twenty dollars to around fifty dollars. They are easy to use, too. All you need to do is plug it into your laptop with a USB cable. Avoid using your laptop outside, especially on hot, sunny days. If your desk is near an east- or west-facing window, be sure to close the blinds or curtains, or consider rearranging your furniture.

If repeated overheating occurs, your laptop can become unstable or even stop working altogether, so take steps to remedy this problem right away. Do not force cotton swabs into tight areas when cleaning. You could damage sensitive components inside. Be careful when using compressed air to clean your laptop, especially near the motor fan. If the air spins the fan blades too much or too quickly it can actually damage the motor bearings. Likewise, don’t invert the spray can during use. This can cause the liquid inside to become extremely cold, which can damage your laptop.
