The motherboard, which is the basis of the laptop, is much different from a similar device located in a stationary computer. This module contains many integrated components that in a regular PC are simply connected to the device using connectors. Thanks to this, the laptop motherboard is small and provides low power consumption.
The negative aspects in this case are problems with heat dissipation, less reliability, lack of interchangeability (unique devices are used in laptops), as well as the high cost of the part compared to the analogue that is part of the desktop computer. These features indicate that repairing the laptop motherboard requires completely different approaches.
There are many reasons why a device stops working. They can be divided into two types. The first includes cases when the board stops working, regardless of user actions. This is due to poor power supply, power surges, factory defects and other reasons. As a result, the charge and power circuits, the north or south bridges, the video card and other components are damaged, which requires sending the laptop motherboard for repair.
The second group of causes of a laptop computer failure includes human actions. Most often this occurs as a result of shock and shock, which lead to microcracks and disturbances in the microcircuits of the connections in various circuit boards. The most dangerous thing is a sharp hit on the buttons, because it is under the keyboard that the motherboard is located.
A great threat to the life of the device is spilled liquid, which penetrates through the keyboard into the computer and directly affects the board. In this case, corrosion of the conductive paths begins, and the device fails. As a result, repair of the laptop motherboard is required.
Other common causes include violations of the operating rules. Here you can highlight the damage associated with overheating of the laptop due to untimely preventive measures, as well as using the device on soft surfaces that are not able to pass air. In such cases, a laptop motherboard repair is also needed.
If you carelessly connect external devices (flash drives), loosening of the connectors may occur and, as a result, a short circuit may occur. As a result, the south bridge burns out , while repairing the motherboard will be expensive.
Separately, the consequences of unprofessional intervention in the implementation of prophylaxis or repair should be mentioned. Laptop owners often try to clean themselves or give their computers to non-specialists. As a result, many devices are damaged. As a result, an attempt to save money results in significant losses. It is very difficult to repair laptop motherboards in a home environment using a soldering iron, it is better not to risk it and contact service centers.
