Office notebook mining smoke

1. Normally, there are no components in a laptop that smoke when working
if smoking occurs, the only explanation is that there is an internal circuit fault, resulting in high temperature combustion or short circuit
in this case, turn off the power immediately and remove the battery to avoid danger
send the book to after-sales inspection, and do not try to power on the machine before the cause is found out, so as to ensure the safety of hardware and personnel.

2. This problem should be the motherboard charging circuit components burned. With the battery and power can be used, you see the battery charging is not normal.. If it can be charged, it is suggested to find someone to open it for inspection. Safety first. If you can't charge, repair the motherboard.. It's a small problem. The cost is not high. However, it is recommended to go to the after-sales department first. If it's free, you can go to the after-sales department. If you charge, you'd better find a small notebook repair shop outside. It's about 100 yuan

3. After the general water, resulting in a short circuit current, the notebook will smoke

4. If you still want to repair it, you can find the nearest computer repair station after power failure to check whether it is caused by the problem of liquid inlet or fan.

5. It must be something burned inside. Find a professional place to repair it

6. Generally, after water enters the notebook, the current will be short circuited and the notebook will smoke,

7. Either the power supply is open or some components are short circuited. It's hard to say if they are broken. It's necessary to dismantle the machine for inspection. The adapter of the computer should also be checked to see if it is burnt out e to the damage of the adapter. Maintenance costs are generally determined by local maintenance standards, plus material costs.

8. The computer host will smoke, which means that the internal hardware of the host will smoke e to aging, wrong connection and other reasons, resulting in short circuit and burning of electronic components. Treatment method:
1. Interrupt the power supply of the host for the first time to avoid further damage
2. As it is not clear which part is smoking, the chassis can be disassembled after the smoke is eliminated, so as to prevent the capacitor bursting and the liquid splashing
3. Preliminarily check whether the main board, memory, host power supply and internal connecting wires are normal, and whether there is conctive substance adhesion on the surface
4. The smoke is usually caused by the breakdown of the power tube inside, the short circuit of the resistor, or the burning of the resistor itself
2. If the voltage rise causes the electrolytic capacitor to burst, there will be smoke, pungent smell and explosive sound
3. If the host computer smokes, cut off the power supply immediately to prevent further expansion of the fault and fire. Send to professional maintenance personnel for maintenance.

9. It's estimated that the burning is not important. Just go and have it repaired a little

10. Smoke should be turned off immediately for inspection. It is usually caused by short circuit. This kind of place is more conspicuous and easy to find. It is mostly caused by aging and damage of components
in addition, if there is no short circuit, check the capacitor to see if there is bulge, which is mostly caused by overheating, just replace it. In addition, sometimes its auxiliary circuit also has short circuit, check it.
