In our age of science and technology, almost everyone has laptops. And every year an increasing number of owners of such equipment seeks to learn to independently understand all the problems that may arise during its operation.
What is the reason for such interest and is it justified? Isn’t it easier to shift all responsibility to repair service workers? Of course, easier. But also more expensive. The fact is that, having determined the malfunction yourself, you can assess its severity, and after that either go to the service or repair the equipment yourself. We must not forget that, as a rule, the cost of repairs is many times lower than the amount that will be required for it in the service.
One of the most common failures is loop damage. As many people know, a loopback cable for a laptop is a special “belt” of elastic material that combines and at the same time isolates a group of wires that serve to combine individual elements of the device.
Unfortunately, this elastic material is subject to deformation and various damages, after which the wiring may be torn. In addition, insulation may be impaired, after which a short circuit will occur.
Thus, the cable for a laptop is very fragile and, at the same time, an extremely important part, if damaged, a system failure can occur.
Of course, after such a breakdown, the laptop will remain in working condition. Most likely, the functionality will not even decrease. However, if the cable for the laptop is damaged, many “floating” problems may appear - system malfunctions that either appear or disappear. Unfortunately, it is quite difficult to isolate such a breakdown, since many of its signs coincide with the symptoms of the “disease” of the matrix or video card.
However, nevertheless, several basic phenomena can be distinguished that indicate that the cable for the laptop is damaged.
So, this damage is indicated by the periodic disappearance of the image on the display against the background of generally normal operation. Also, a violation of the integrity of the loop is indicated by image distortion when lowering the lid of the laptop, as well as when moving the device. There may be problems in the operation of the optical drive, as well as the arbitrary shutdown of the device during operation.
It is possible to fix a cable for a laptop, the question is where it is better to do it - in the service or at home. Of course, professionals will definitely do everything right, but their services are very expensive.
If the owner of the equipment is confident in his abilities, then he can try to fix the problem on his own. To do this, first of all, you need to buy a cable.
The cost of this element is relatively low, but it all depends on the manufacturer. So, a cable for a Samsung laptop costs a little more than
five hundred rubles. The reason for such a low cost is not very high popularity of the company and the average quality of parts. But the cable for the Acer laptop costs almost a thousand, since this company is more popular, and its equipment and parts are famous for high quality and durability.
All that remains is a direct replacement of the failed part of the loop. To do this, you need to disconnect the laptop from all power sources, remove the front panel of the screen (this is necessary in order to get to the matrix), remove the matrix, replace the damaged cable with a new one, fix it and assemble the display. If after assembly the device works properly, then everything is done correctly.
