TIPS FOR THE CARE AND CONSERVATION OF A PORTABLE COMPUTER. Memories

While it may seem (and some manufacturers try to) a laptop is just like a desktop computer, the truth is that they are not. There are many variables and constraints that have made big differences between them, and not only in performance.
A laptop needs a series of specific care and maintenance is different than a desktop computer, and it is this aspect that we focus in this tutorial.
risks of failure and tear on this type of computers come in many of its own characteristics of mobility and small size, so much special care must focus on these points.
Transportation:
The biggest advantage of a laptop is the ease they have to be transported from one place to another, but this same facility is one of its main weaknesses ... and reason for failure. When you transport a laptop have to keep in mind that are not particularly strong, so that we protect in the best way possible. Ideally
for transportation is to use a bag specifically designed for that purpose. There are many market it bags of different sizes and strengths. We find a bag that has a really good cushioning and protects the computer, avoiding any elements that transport them if they can be very comfortable are very inadequate for that purpose, such as in a backpack. A fall or a blow can cause damage at least very expensive to repair.
Location:
We mean by placing a place where when you use the laptop. Undoubtedly it is very comfortable to use it anywhere (in bed, on his knees on the couch), but these sites have a number of risks to the laptop. Addition increase the risk of falls, we also have the laptop on the move while it's moving parts are in motion, such as hard disk drives readers. In fact, these habits mean that, despite being hard drives with less inertia than a normal hard disk, with designs optimized in terms of mobility and usually with lower rotational speeds, have a failure rate somewhat higher than average.
this point also influences the ventilation and cooling of the notebook, making it difficult in many cases the proper cooling.
When you're using, the ideal place to put a laptop is about a table (or at least on a hard flat surface), with good ventilation and if possible on a stand refrigerant.
Use:
laptops have a serious drawback: Air considerably less than a desktop computer. It is true that normally are designed to withstand a higher operating temperature and generate less heat than a desktop computer, but this does not equate to both types of computers. A laptop is NOT designed to be working continuously for hours (or even days, as is the case of a desktop computer), and if it is true that a good external cooling helps a lot, we must also bear in mind that the life of your laptop may be reduced.
Another weakness comes from its own structure. The display is part of the team cap, which makes this a very heavy element. Well, with the use (especially when we have the habit of being constantly moving the screen, as it happens to more than one) the hinges of the lid catch slack, making the end result really hard to find a position in is stable. This may also ultimately affect the same connection between the screen and the computer itself.
Battery:
Laptops can operate connected to the mains network by incorporating battery. This battery is usually a rechargeable lithium ion battery, which have a limited shelf life because they lose the use of cargo capacity. The average life of a battery is about three years, but this time you can see shortened by a misuse of the battery. Although we use the laptop connected to the network is highly desirable from time to time we use it with battery, allowing it to fully discharge.
Clean:
Cleaning is a very important point in every PC, but on a laptop is even more important. Let's see how we can clean different parts:
- Exterior .- It is best to arrive no need to use any liquid for cleaning, but for that we have no choice but should always be non-abrasive liquids, which have a high rate of dissipation and above all, never apply them directly on the surface, always apply on a soft cloth, with the later clean exterior surfaces, drying them immediately in full.
- Display screen .- For the best is to use the wipes used for cleaning optical lenses and glasses, without applying excessive pressure. There are special wipes to clean computers.
- Keyboard .- The keyboard must ensure that never arrive dirty, but if it gets dirty we can clean it with the same screen, that is, with some wipes for cleaning glasses or with special wipes for cleaning computers.
Special care:
addition to the above, we must be especially careful with laptops, as any blow (let fall) or liquid spill over effects is usually quite serious and costly to repair. A cola on a keyboard is fixed with 10 euros. This same soft drink on a laptop may mean in most cases the total deactivation of the laptop or at least enough compensation expensive.
One element that must take special care on a laptop is the optical drive (readers or rewritable CD / DVD). These units, which in a desktop computer well protected are the most important elements in a laptop's are fully exposed to both dust and shock. We must be especially careful when we use them as a blow or misuse can easily mean rupture.
We must bear in mind that involves repairing a laptop in most cases having to resort to a specialized technical service, and that the components of a laptop are much more expensive than the same components for a PC, so good maintenance and care of we can save you big money.

What Salon In Alabama Sewn In Extensions
random access memory, or direct memory access (in English: Random Access Memory, RAM acronym), or better known as RAM, is composed of one or more chips and used as working memory for programs and datos.Es a type of temporary memory that loses its data when out of energy (eg by turning off the computer), so it is a volatile memory. This is true from the theoretical point of view: Scientists from Princeton University have discovered that there is a gradual destruction of data stored in RAM ranging from a few seconds to several minutes, being inversely proportional to temperature. This could mean a security breach while the access key information such as BitLocker ciphers are stored in RAM.

THE MICROPROCESSOR MODULE 1
The microprocessor is an integrated circuit that contains all the elements necessary to constitute a "central unit processing "UCP, also known as CPU (for its acronym in English: Central Process Unit). At present this electronic component is comprised of millions of transistors, integrated into a single silicon wafer.
microprocessors for sale usually come packaged to protect the element silicon (the chip itself) of electrical interference and damage from exposure to the environment, this usually packaged or parallelogram prism and includes conductive surfaces or poles to allow passage of power and electrical signals to and from the microprocessor. This packaging is commonly installed on an element called base (in English, socket) that serves both Anchorage and communication interface between the microprocessor and the rest of the computer (eg, communicating with the chipset). In some architectures the microprocessor can be welded directly to the motherboard (motherboard). There are also architectures which adopted the cartridge format, however this format is rather rare today, preferring the microprocessor industry have independent modules can be connected (and swappable) in a special socket.
