★ Common knowledge of laptop power adapter★

1. What does the nominal voltage and current on the power adapter (hereinafter referred to as the power supply) mean?

The nominal voltage of the general power supply, that is, the rated voltageIt refers to the voltage of the output of the open road, that is, the voltage of no load outside, without current output.The nominal current value refers to the rated current of the power supply design, that is, the working current when the maximum load of the power supply design. From the formula of the current I = voltage V/resistor R, it can be known that the working current of the power supply is changing with the load change.That is, the working status of the computer determines the working current of the power supply.So do n’t ask the rookie -level problem when buying a power supply: your power nominal current is larger than mine, will you burn my machine?Those who ask such questions should read the junior high school physics book and read it again!Regardless of any power supply, there is a certain internal resistance, so when the power supply output current, the internal voltage drop will be generated, resulting in two things: one is to cause the output voltage slightly, which is equivalent to internal consumption;It will heat.

2. They are all power supplies with the same nominal voltage, and the output current is different. Can it be used on the same notebook?

It is best not to use a small current power supply instead of a large current power supply, which will cause the power supply to work in a high load state, which is easy to heat or burn.In fact, without the same current, large current power sources can be replaced by small current power supply, but it is generally not too large, because the larger the current of the power supply, the greater the power loss power of the heat loss. From the perspective of energy saving and environmental protection, the energy saving and environmental protection, and the energy saving and environmental protection, the energy saving and environmental protection, and the energy saving and environmental protection.Try to avoid this.Of course, because of the big horse, large -current power supply is used on small current machines, which is even more difficult to damage.When designing a computer, the voltage and current have an error range, positive and negativeThe voltage and current of the power supply within 10%of this can be compatible with compatibility.

3. The same machine, the power of others is warm, and I am always hot. Why?

Don't doubt that your power supply is wrong first, first see what your original book is doing, is it like an external device too much?CPU runs at full speed, the hard disk is crazy read and write, the optical drive reads the disk at full speed, and at the same time charges the battery, placed music loudly, the screen brightness is the largest, the wireless network card has been detected signals, etc.The state is very important, energy saving and environmental protection.

4. The power nominal voltage is much higher than my original battery voltage, willn't it happen?

First of all, we must know that the power supply to the power supply is different from the battery.

The battery powered, the output of the battery is pure DC, which is very clean, and the voltage of the battery is neither possible nor designed very high. The chemical characteristics of the lithium battery determine that the output voltage of a battery cell can only beAbout 3.6V, so many batteries use a three -level series, and 10.8V has also become a very popular battery voltage.The nominal value of some batteries is slightly larger than an integer of 3.6V, such as 3.7V or 11.2V, etc., in fact to protect the battery.

The situation of power supply is more complicated. First, further voltage-regulating filtering is required to ensure stable operation when the power supply performance is not very good. The voltage after voltage stabilization is divided into two parts, and the power supply to the book will be supplied to the work of the book., the other way charges the battery. The part that powers the notebook is the same as when the battery is powered. The part that charges the battery needs to be added to the battery cell through the charging control circuit of the battery. The control circuit can be very complicated, so the power supply isThe voltage must be greater than the battery voltage to have sufficient capacity to supply to each unit of the charging control circuit.The voltage that is actually applied to the battery cell will never be the nominal voltage of your power supply.Don't worry!
