Repair laptop motherboard: types of breakdowns

The motherboard, which is the basis of the laptop,in many respects differs from the similar device located in a stationary computer. This module contains a lot of integrated components that are simply connected to the device in a conventional PC using connectors. Thanks to this, the motherboard of the laptop is small and provides low power consumption.

The negative moments in this case areproblems with heat removal, less reliability, lack of interchangeability (laptops use unique devices), as well as the high cost of the part in comparison with the analog that is part of the desktop computer. These features indicate that the repair of the laptop motherboard requires completely different approaches.

There are many reasons why a devicestops working. They can be divided into two types. The first is when the board stops working, regardless of the user's actions. This is due to low-quality power supply, voltage surges, factory fault and other reasons. As a result, the charge and power circuits are damaged, the north or south bridges, the video card and other components, which requires sending a laptop to repair the motherboard.

The second group of reasons for the breakdown of the portablecomputer includes human actions. Most often this occurs as a result of shocks and shocks, which lead to the appearance of microcracks and violations in the microcircuits of the connections in various boards. The most dangerous is the sharp impact on the buttons, since it is under the keyboard that the motherboard is located.

A big threat to the life of the device isspilled liquid that penetrates through the keyboard into the computer and directly affects the board. Corrosion of the conductive paths starts, and the device breaks down. As a result, the laptop motherboard needs repair.

Other common reasons includeviolation of the rules of operation. Here you can identify the damage associated with overheating of the laptop due to inopportune prevention, as well as using the device on soft surfaces that can not pass air. In such cases, it is also necessary to repair the laptop motherboard.

If you carelessly connect external devices(flash drives), the connectors may loosen and, as a result, a short circuit may occur. As a result, the southern bridge burns, while repairing the motherboard will be costly.

Separately, mention the consequencesunprofessional intervention in the performance of prevention or repair. Owners of laptops often try to clean themselves or give their computers to non-specialists. As a result, many devices are damaged. As a result, the attempt to save turns into significant losses. It is very difficult to repair motherboard laptops in the home with a soldering iron, it's better not to risk and contact the service centers.
