Q: Plug in the power adapter when the power switch without any reaction, even the lights are not bright. But the power adapter is no problem, plug in the power adapter after boot in the absence of the battery can also be used normally. When the battery is switched on, you must turn on the notebook (the hair dryer blows, placed on the electric blanket or placed in the sun).: The battery is broken or charge and discharge the chip is not recommended to use this battery only use the power adapter. Help solve computer-related issues, have questions directly asked, do not hesitate. Direct question or Baidu Hi can be, my personal information in the button and telephone consultation can also be. Beijing can find me, other provinces can also guide the relevant attention and so on.

Q: Does the laptop power adapter pull off the mark for a long time?: Extension: In fact, not only laptop power adapter will be so, Some mobile phone or tablet computer charger indicator will have the normal phenomenon.

Q: Tsinghua Tongfang laptop power adapter lost, who knows the parameters, input voltage and output voltage?: 90W 100-240V Universal Adapter Universal 90W Adapter (LS-PAB90MH) Notebook 90W AC Power Adapter, Input: 100- 240V, 50 / 60Hz Laptop 90W universal AC power adapter Input: 100 - 240V, 50 / 60Hz Output: 14- 24V Size: 115 x 50 x 35mm Weight: 420g

Q: LED ceiling lamp drive power can not help, want to know whether the use of laptop power adapter is feasible. Thanks a few teachers. If not, with mobile phone charger transformation ok? How to change: What are the drive power parameters? Mainly the output voltage, the output current. Adapter power supply if it is not enough light is not bright, the phone charger voltage is generally 5V, the current is generally 500-1000mA. The voltage is too much current too light and then easy to bad, so to directly replace the words is not feasible.

Q: The standard for my original factory adapter is 100-240v 50-60Hz 1.5A 1.9v - 4.74A 90W MAX The new adapter is 100-240v 50-60Hz 2.6A 1.9v / 4.74A Can you use it? The new adapter output current high 1.1A no damage to the notebook, right?: Depends on the reason the notebook burns is: voltage. The voltage is too high the notebook will burn. The current line of your adapter and the line of the adapter board will be large, and the notebook did not matter much. Directly point: If the adapter current is too large Your plug-in board diameter will be large, and the current power consumption is also large. You have a big 1A no thing, the general line of household electricity enough to drive 16-20A. Please feel free to use. Professional electrician.

Q: Laptop power adapter squeak how to do: If there is no power supply instability, or the sound of the big situation is generally a normal situation, because the power adapter in the conversion of the power supply is bound to issue a fixed frequency of the sound, different frequency of the inductance coil due to its rated power Is not the same, so the size of the induced current sound is not the same, you can ask if the customer can replace. But if you do not cause other problems theoretically can refuse to replace. Some problems with the power adapter: First, the general power of the nominal voltage, is the open circuit output voltage, that is, outside the load is not connected, there is no current output voltage, it can be understood that this voltage is the upper limit of the power output voltage. For the internal use of the active power regulator components, even if the mains voltage fluctuations, the output is also a constant value, as the market generally small transformers, such as portable with the type of power supply, if the electricity fluctuations, The output of the power supply will fluctuate.

Q: Why laptop power adapter do so big can not make mobile phone so small?: Because the voltage of the notebook is very large

Q: Samsung r423 laptop power adapter interface model is exactly how many millimeters: General Samsung notebook computers such as NP series, power interface are 5.0x3mm, with a needle.

Q: Why is the laptop power adapter look so big?: The shape of the adapter is of course to stabilize the voltage, the large voltage into a small voltage, as to why the adapter can stabilize the buck, you can query the relevant knowledge. And three trunks that play the role of security protection. You can go to Baidu look, learn what is FireWire What is the zero line what is the ground line. These are secondary school knowledge.

Q: The laptop power adapter has been ringing, and the charging indicator flashes repeatedly. What's the matter?: On the laptop when charging, the power indicator flashes, but also charge into the power. From the problem, generally have the following: 1, may be the power adapter of the power connector, due to poor contact; or battery interface then Touch the wrong; can check the next. 2, may be caused by a battery failure. Lu master with the next test, the battery work Look at the current loss of the battery to determine whether the battery is damaged. 3, may be the motherboard power control, charge and discharge circuit is damaged due. If the master with Lu detection The battery is good, that is, the motherboard power supply and discharge circuit is damaged. Please go to the local after-sales inspection as soon as possible, and replace the new module to solve;
