Why things break

Over the years of our inventions, we often face the fact that they break down.

Computers, they are sensitive to dust and falls. What I mean is that they can get slower just by gendering up dust in the hard drive area. There is a fan in the hard drive just to clear it from dust but it's only active when the computer is running. If the computer is in stand by mode or turned off, the fan won't work because they program tells it to switch off to save energy.
If you feel the heat right next to the computer or you hear the fan blowing for a long time without pause, it's time to clean it.
When you are going to clean the computer form dust, it's important to have the computer turned off, if you don't turn it off you may destroy the fan or the inside yourself.

To clean the hard drive you can use a vacuum cleaner and a needle or a needle and an air compressor to either suck out or blow out the dust. You might now wonder "why do I need the needle to clean the computer?" The fan in the hard drive have it own rotation and if don't stop it from moving might blow or suck it out of order which would destroy the cooling and self cleaning process.  The needle can stop the fan to move and it will not go out of order.

When you have done the cleaning your computer will go a little bit faster because it need less energy to the fan to clean the hard drive.


As many other divvies, computers have gotten a bit safer from breaking down by falling down, however if it falls to often, even a minor fall, could break the circuit card and the computer won't work even if it looks okay.
There is a reason computer can withstand more falls and that is the design of them. The designers have worked with how the model of the computer should take the impacts of the falls the may come in the further, but no matter how much work you put in the design, computer will break easy if it falls to often. The main reason is those minor and sometime invisible cracks and these cracks will grow bigger and bigger for each time the computer fall down to the flour. The impacts shouldn't reach the circuit card because it can't withstand them that well as the shale. With many minor cracks in the shale than the impact will sooner or later reach the circuit card and jeopardize the data and the life of the computer. Having backup copy would help you if the computer would break down and you won't lose that much data when it happens.
