Q: How can I identify the true and false laptop power adapter method?: Guande letter meter technician to help you identify: First, from the label to distinguish the true and false notebook power. True and false notebook power comparison. Assemble the battery on the left side of the label font is small and more vague, and the original genuine difference; original power on a layer of film, while the assembly is not. Second, from the pad to distinguish the true and false notebook power. False power supply pad feet are large and appear rough. Third, from the plug to distinguish the true and false notebook power. The original power plug inside the pin work more fine, and the assembly uses a spherical pin, and in the surrounding edge left a large gap. The most obvious difference is that the position of the two plugs, the original power supply in the center, and the assembly is in the side of the bias.

Q: Bought a power adapter on the Internet, although the same parameters, but when the product was found not wrong interface: buy a small hole interface, the notebook is a large hole. Now want to know the market can not find the conversion interface?: You go to the place where the adapter to buy a change is not on the mouth of the voltage and current are not equipped with do not put the battery burned

Q: My computer power adapter plug in the power will be sounded, but the computer did not sound after the boot, what is the situation? The output of my power adapter is 19.5V ~ 7.7A I may not say clearly, my adapter can be used normally, but he plug in the power (alone plug the computer is not connected to the computer or the computer is not boot) will have a voice, others say the adapter in the power when there is normal voice, Of the adapter in the no-load when the sound is great: To judge this is very simple: 1. Computer in the battery state to see if it is working properly. If you do not work, the battery has a problem 2. Remove the battery in the computer with a power adapter to see if the power is working properly. If you do not work, the power adapter has a problem 3. If the two states can work that is the computer charge management part of the poor contact and other issues.

Q: After my laptop power plug in, the following icon shows the charge, but wait for a while, it shows no charge. Hand pat the adapter, and sometimes will be good. I feel the problem lies in the adapter, ask the master how is this going on? How can I fix it?: Depending on what you say, the pat adapter is sometimes good, and the power adapter may be in poor contact. If you have no insurance, then you can report directly to the sale after the test, they will help you get. If the insurance, but also to get after the sale to check to see what the problem is, if the adapter is the problem, do not repair, because the maintenance costs are more expensive, you can go to the electronic city to buy a computer model and match the cottage Adapter, also very durable. Do not disassemble and repair yourself

Q: Power can not be charged, and only to keep electricity, but the power less and less. Tried several times off the battery, boot, the power is useless. Socket also changed. There is no power supply around the same model. Seeking solutions ah: That's where you have a power adapter problem. Change the power adapter. Recommended Taobao to buy, the official website more expensive.

Q: And that the output connector size is not the same, if you can substitute, then I intend to change that connector: Suggest not to use Take a notebook to the computer city to buy one, cheaper points twenty-three one So safe, do not buy the original, buy an ordinary but you can apply for this model

Q: Is the desktop adapter's power adapter and laptop power adapter common?: As long as the interface, the output voltage and current, you can use, otherwise no

Q: Laptop power adapter squeak how to do: First of all, to know is that the power supply to the books and the battery power supply to the notebook is different. Battery-powered, the battery output is pure DC, very clean, the battery voltage is neither possible nor need to design a high, lithium battery chemical properties determine a cell output voltage can only be about 3.6V, so Many batteries are used in three cascade way, 10.8V also became a very popular battery voltage. Some batteries are slightly larger than the integer value of 3.6V, such as 3.7V or 11.2V, etc., in fact, to protect the battery. Power supply, the situation is more complex, first of all need to add voltage to further regulation filter to ensure that the power performance is not very good in the case of stable work, the voltage regulator after the two parts of the city, all the way to the work of the power supply , The other way to the battery charge to the part of the power supply to the battery when the same power supply, and the part of the battery charge through the battery charge control circuit can be added to the battery, the control circuit can be very complex, so the power The voltage must be greater than the cell voltage to have sufficient capacity to supply the charge control circuit to the units. Finally the voltage actually added to the cell will never be the nominal voltage of your power supply. Rest assured. Hope that the above information is useful to you

Q: Do you have a big impact on your notebook with a high imitation power adapter?: Notebook is not one hundred, two hundred things, buy a homemade it, after the sale of high prices, you can go to Jingdong, the new egg to see if there is no, where cheap
