Why is it easy for notebook motherboards to burn?

Are you curious why laptops often burn the motherboard? PHP editor Strawberry revealed the common causes of such failures. Whether you're a laptop user or someone who wants to know more about its inner workings, read on to learn more about what causes a blown motherboard and learn how to take precautions to protect your device.

Why is it easy for laptops to burn the motherboard?

1. Overheating: Factors such as long-term use, fan failure or dust accumulation may cause the internal temperature of the computer to be too high, thereby damaging the motherboard.

2. Overvoltage: The output voltage of the power supply or charger is too high, or weather factors such as lightning strikes may cause the computer motherboard to overvoltage and burn out.

3. Short circuit: A short circuit in the circuit on the motherboard may cause the motherboard to burn out.

4. Liquid immersion: Liquid splashing into the inside of the computer may cause a short circuit and burn out the motherboard.

Why does my laptop charging motherboard burn out?

The computer is turned on for a long time, which makes the temperature of the notebook too high. In addition, the heat dissipation performance of the notebook itself is not very good. If the temperature is too high, the motherboard will naturally be burned out.

You can buy a good cooling pad, use it in a cool place, use it for a period of time, shut down the notebook and other measures to reduce the occurrence of motherboard damage

What is the reason for the motherboard to be burned during a power outage?

Mainboard damage caused by power outage is usually due to one or both of the following two reasons:

1. The power grid recovers after a momentary power outage or the voltage suddenly rises when the power is restored after a power outage, resulting in The capacitor voltage on the computer motherboard was too high and burned out. Capacitors are a critical electronic component on the motherboard. They can store energy and smooth current to ensure that the computer works step by step and stably. If the energy stored in capacitors exceeds their rated capacity, they are likely to explode or burn out.

2. After a power outage, some electronic components on the motherboard will experience excessive pressure and voltage inversion, causing damage. This usually happens with power supply filter capacitors and voltage regulators. During a power outage, these components will be affected by electrical oscillations or surge pulses, and some components will be overvolted and burned out.

In order to prevent a power outage from burning the motherboard, it is recommended to use stable power supply equipment, such as an uninterruptible power supply, to maintain a stable current to the computer motherboard, and at the same time shut down the computer and related equipment in a timely manner during a power outage. In addition, when using the computer, pay attention to situations where the voltage fluctuates greatly, such as in stormy weather or when using high-power electrical appliances. Turn off the computer in time to avoid damage to the computer motherboard.
