Laptop ac adapter heat causes and solutions

It is normal for it to work, to convert the output, it will consume energy, there will be a part of into heat also depends on whether you installed on the battery or the battery is normal. Laptop power adapter is actually a high-precision, high-efficiency switching power supply, its role is to 220v AC power is converted to low voltage DC to provide stable power for the normal work of the notebook computer, it can even be called a notebook the computer “source of power.”
Notebook power adapter is about questions and answers. Such as:
Q: Why exactly the same machine, Managing someone else’s notebook power adapter , I always very hot?
Do not doubt your dell power adapter , take a look at your books are doing, is not like the above said two usb hard drives, cpu is running at full speed crazy, hard to read and write, CD-ROM drive at full speed to read the disk, at the same time charging the battery , stood loud music, screen brightness, wireless LAN has been in the detection signal, the use of power management, according to the task of rationally adjust the books of the state is very important. Many people do not like to use power management, I have even seen many of my friends do not want to install power management software to any kind of management mode is enabled, it is also fitted him to do? Will not be just want to look at the battery remaining percent How much it?
Q: I filled the battery-line power when the dell latitude e6400 adapter is not too hot, but do not install the battery for a burnt to death on normal? Why?
I filled the battery-line power supply when the power adapter is not too hot, but do not install the battery for a burnt to death on normal? Why
Batteries, notebook power adapter to charge the battery by battery driven books, the battery is medium. To remove after the battery. Becomes the adapter directly to start the notebook. Charge and DIP are different concepts. When charging, you should look at the battery’s hot? Are normal. Rest assured it.

I recently bought a laptop computer, notebook power adapter and pressed but I only spent about 30 minutes like hot ah ask the computer problems are so I use it every time
In theory, it is normal
Itself the power adapter is not a good heat dissipation, and his interior is a large inductor constitute a necessary way of the current transfer box is closed, plus it is summer, if you heat does not exceed your hands the ability to accept that are normal, I believe that I am not wrong, your computer and power adapter all I own in the laptop repair years ~ ~
Inside the lenovo laptop power adapter is a switching Dell XPS L702X AC Adapter , high voltage, high current state, the workload is heavier, and is fully enclosed structure, there is no cooling holes in the shell, the internal fan to the auxiliary heat, thus the laptop power supply adapter at work, the internal temperature is very high. Especially during the hot summer, touching the surface you can feel hot, the internal temperature is higher. Which the daily office, entertainment to its proper maintenance and maintenance.
(1) to create a good thermal environment
Use of laptop computers in the high temperature environment, the dell pa-4e ac adapter to place free from direct sunlight and well ventilated place; power adapter on the laptop near the cooling air outlet, otherwise not only the heat of the power adapter dissemination does not go out, but also absorb some of the heat. In the hot summer, we can put the adapter on its side in order to increase the contact area of the adapter with air, so that the adapter heat better distributed out. In order to get a better cooling effect, we can pad between the adapter and the desktop into a narrow plastic block or piece of metal in order to increase the air convection speed of the adapter around, speed up the adapter’s heat.
2 exception occurs shall promptly stop using
Loud noise or smoke in the laptop ac adapter is often damaged or malfunction, should immediately stop using once again put into use only by maintenance by a professional engineer.
(3) a reasonable charge
When the laptop battery is charging, it is best not to run large-scale 3d games and other procedures for the machine heavy workload, so because of the amount of surplus power adapter output power is not enough battery charge slower or sufficient dissatisfaction, overloading the power adapter.
Four different models of notebook power adapter can not be mixed
Different brands of laptop power adapter, there are some differences in output, voltage and current values, and therefore can not be mixed. Otherwise, ranging from the battery sufficient dissatisfaction with the power, the screen flashing, the weight is to burn the notebook computer motherboard or other hardware. Different models of the same brand notebook power adapter in the other time also should be careful, it is recommended to consult professional engineers after the operation.
Hot in summer so the dell DA130PE1-00 adapter fever is inevitable, we must pay attention to the thermal environment. Due to rapid market development of the technology development notebook power adapter and switching switching power adapter , power adapter will be more convenient.
