The power adapter is very hot. This is a hot state, which means that the power adapter has been working and continuously converting and outputting electricity. As long as the temperature of the power adapter is within the design range, there is generally no danger.
In order to obtain better heat dissipation effect, we can also insert a narrow plastic block or metal block between the adapter and the desktop to increase the air convection speed around the adapter and speed up the heat dissipation of the adapter.
If the connected power supply is unstable, or the power supply is too high or too low, it will cause problems such as the notebook power adapter becoming too hot. If it is found that this is the cause, it is best to replace the power plug. This answer applies to most computer models such as Dell Vostro3668.
Create a good cooling environment. When using a laptop in a high-temperature environment, the power adapter should be placed in a ventilated place away from direct sunlight. Do not place the power adapter near the cooling air outlet of the notebook, otherwise not only the heat from the power adapter will not be dissipated, but some heat will also be absorbed. If an abnormality occurs, use should be stopped immediately.
First of all, the conversion efficiency must be designed to be as high as possible. Secondly, switching components with small voltage drop and low loss must be selected. Thirdly, heat dissipation design must be carried out. The heat dissipation area must be as large as possible, 100W The above switching power supply should generally have a metal perforated casing or a cooling fan.
1. Try to place the power adapter in a place with good ventilation and heat dissipation. Do not place books or other things on the power adapter to avoid damage. heat dissipation. When using a notebook in summer or in a high-temperature environment, the notebook power adapter should be placed in a ventilated place away from direct sunlight.
2. Since mobile PC does not have a battery, the power adapter is particularly important for it. If the power adapter is so hot that it is hot to the touch, then the temperature is abnormal and it is recommended to go to customer service for replacement. If it doesn't feel hot, it's normal.
3. Solution: Place the computer in a place with good heat dissipation environment. Move the adapter away from the heat dissipation outlet, or insert a narrow plastic or metal block between the adapter and the desktop to increase the air convection speed around the adapter and speed up the heat dissipation of the adapter.
4. Generally, it does not affect the use. If the adapter is broken, just buy one. Laptops have protective isolation circuits, so you don’t have to worry about damaging the laptop. Fever is normal. If the fever temperature is constant, it is normal. The reason why the laptop gets hot is due to insufficient heat dissipation caused by excessive dust on the computer host.
5. Create a good heat dissipation environment. When using a laptop in a high-temperature environment, the power adapter should be placed in a ventilated place away from direct sunlight. Do not place the power adapter near the cooling air outlet of the notebook, otherwise not only the heat from the power adapter will not be dissipated, but some heat will also be absorbed. If an abnormality occurs, use should be stopped immediately.
6. However, the maximum power requirement of some brands of mid-to-high-end gaming laptops exceeds 65W. Because the power supply is powered by both the adapter and the battery, only a 65W adapter can meet its usage needs, but it will cause the adapter to load. Higher or even full load, resulting in increased heat generation.
It is normal for the laptop power adapter to be hot because during the voltage conversion process, part of the energy lost is emitted in the form of heat. As long as it's not particularly hot or hot to the touch, don't worry about it, it's normal. It is normal for the charger to be a little hot when the notebook is being charged, so don’t worry too much.
It is normal for the laptop's power adapter to become hot after being powered on and used, so don't worry. This has nothing to do with the length of use. It will become very hot after one or two hours of use, but it will not maintain this temperature forever. And the shell of the notebook power adapter is high temperature resistant and will not burn out.
It is basically normal for the laptop power adapter to be hot and make noise, unless the temperature is too high or the casing is damaged or the sound is obviously loud, then there is a problem. Generally, it does not affect the use. If the adapter is broken, just buy another one. Laptops have protective isolation circuits, so you don’t have to worry about damaging the laptop.
unusual. Generally speaking, it is normal for a laptop charger to be hot, but it is not normal for it to be extremely hot.
This is normal. The laptop charger is also called a transformer. It needs to convert the 220V voltage from the wire into the voltage required by your laptop (such as 14V, 19V, etc.). Of course, during work It will become hot. Laptop charger maintenance method: Create a good cooling environment.
When the laptop is charging, the power consumed will cause the power adapter to become hot, but when the battery is saturated and charging is completed, the hotness will be alleviated. Under normal use of AC power, the computer will also become hot, but when the weather is hot in summer, the heat will be more obvious.
The above is the detailed content of Laptop power adapter is hot. For more information, please follow other related articles on the PHP Chinese website!
