Why does the laptop slow down?

The laptop serves as a loyal assistant to many people who have the need to work with computer programs while being away from home or office. It is very unpleasant when the opportunity to work with this expensive device is limited to where it is unclear from which to take "glitches" and "brakes". Let's see why the laptop slows down what to do in such situations and how to identify the alleged cause of this “behavior” of the device.


The data in the laptop (as in the PC) is stored on the hard disk. Physical areas on the surface of the disk, in which, in fact, information is stored, are called sectors. A group of sectors arranged in series on a disk surface is called a cluster. When writing data to a weakly filled disk, clusters are filled with information sequentially, and large files occupy several clusters, going in order.

However, it often happens that large files are split between clusters that are distant from each other on the disk surface.This happens when there is little free space on the disk or when it is filled and cleaned several times by deleting files. This type of recording is called fragmentation. Accessing a fragmented file requires reading information from different parts of the disk surface. This, in turn, requires an increase in the amount of mechanical work performed inside the disk, and the laptop is very slow. In such situations, quite often you can hear a sound similar to starting a small engine with high revs.

The process of reordering files to reduce their fragmentation is called defragmentation. It is performed using standard utilities of any Windows operating systems (Start -> All Programs -> Standard -> System Tools -> Defragmentation).


The dust that gets inside the laptop is deposited on the surfaces of the device's microcircuits. As a result, the possibility of heat transfer to the microcircuit case is reduced. Because of this, the processor, memory chips, and other chips overheat. The performance of semiconductor devices decreases with increasing temperature. Accordingly, if over time the laptop began to slow down, then the reason may be a large amount of dust that has settled on its internal surfaces.A sign of this situation may be an increase in the temperature of the device.

To get rid of dust, you need to disassemble the laptop and process it from the inside with a special vacuum cleaner and, if necessary, perform a manual cleaning of dust.

Attention! It is not recommended to disassemble, and even more to carry out service work with the "iron" of the laptop to a person who does not have special training. Therefore, if you suspect that you have encountered a problem that requires disassembly of the device case, do not save on the services of the service center.


These programs, destructively affecting computer hardware, can be “found” all over the Internet. Using antivirus systems and updating them regularly does not give a 100% guarantee that your computer will not become infected with viruses (however, antivirus software with current databases greatly reduces the likelihood of infection, so its use is necessary if you work with the Internet). If you notice that you have slowed down your laptop, you may have caught one or more viruses.

Perform a full system scan for viruses.First, check the disks and RAM with your regular antivirus program, then download one of the utilities that do not require installation from another company (they are distributed by almost all anti-virus software vendors for free) and check your computer with it. The use of products from two or three manufacturers is likely to reveal all suspicious objects.

On the other hand, the antiviral programs themselves can be the cause of "brakes". For example, when launching the same game, or the same software, which requires a large amount of system resources (such as Photoshop or video editors), the antivirus program can scan it every time, which will take a large amount of time. In some cases, a virus scan can run in parallel with the operation of the software. This will lead not only to a prolonged launch of the program, but also to a decrease in its speed. Therefore, it is advisable to add some programs to the trusted area of ​​the antivirus software.


Buying a desktop computer, you pay for performance. Buying a laptop, you also pay for the compactness of the device, which is very expensive.Therefore, one of the reasons why a laptop is slowing down may be insufficient system performance. There is nothing surprising in the fact that a $ 1,000 laptop works more slowly than a computer, for example, at $ 700. When buying a laptop, the user must understand that he is compromising the speed of the system. To expect that the laptop from the average price range will draw the latest 3D games, at least naively. For this you need to lay out the amount of 1,5 thousand dollars.

In addition to games, resources can "devour" and OS. For example, installing Win7 on a laptop that was developed for Win XP can significantly reduce performance. "Seven" requires a minimum of 4GB of DDR3 RAM and the presence of at least a dual-core processor.
