Q: Laptop power consumption is 117 watts but the power adapter is 90 watts what the situation?: Power adapter maximum output power of only 90W, then the machine's power consumption can not exceed this value, the hardware mark prevail, the software is not measured out of this, but according to the various models of hardware projections, for reference only Only, there is no practical significance.

Q: The original 65w bad, sometimes with less than 65w, can 90w it?: As long as the interface can, 90w can replace 65w. -------------------------------------- Reference: Power supply voltage, the output current is different, can not be used in the same books. The basic principle is that the large nominal current supply can replace the small nominal current supply. It is estimated that some people would like to think that a large nominal current power will burn books, because the current big thing. Actually how much the current in the case of the same voltage depends on the load, Oh, think of junior high school physics to know. When the books of high-load operation, the current larger, the books into the standby time, the current is smaller, the nominal current power supply has enough current margin. On the contrary, some people use 56w power supply instead of 72w with no problem, because the power adapter is usually designed to leave a certain margin, the load power should be less than the power supply, so this replacement is generally feasible in the general use, But the remaining power supply power margin is very small, once your books received a lot of peripherals, such as two usb hard drive, and then cpu full speed operation, and then a base, the above to drive a full speed to read the disk, plus at the same time To charge the battery, it is estimated that the danger, and at any time to touch your power is not already boiled eggs. So it is best not to use a small current instead of high current power supply.

Q: Dell laptop can not open the machine, the indicator light is not bright, plug in the power indicator light is not bright: (1) Remove the power adapter and battery, the host is not powered in the case, hold down the boot button does not move for more than 30 seconds to release the notebook may be residual static; 2. Separate power adapter to try to boot; 3 . Separate the battery to try to boot; 4. If conditions permit, you can plug the memory test. If the above method is still not normal use, then it is recommended that you go to Dell after-sales maintenance in detail.

Q: I am a Lenovo G550 notebook, the original adapter output voltage is 19V 4.74A. Now I got an original adapter, which is on another machine, the voltage is 20V 4.5A. Do not know this user will not have any harm to the computer, I see the Internet has a different power will burn the machine and the like, so ask everyone. Thank you!: Lenovo power adapter voltage and current problems: First of all, the general power of the nominal voltage, refers to the open circuit output voltage, that is, do not take any load outside, 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. Generally speaking, the actual no-load voltage of the ordinary power adapter is not necessarily the same as the nominal voltage, because the characteristics of electronic components can not be completely consistent, so there is a certain error, the smaller the error, the higher the consistency of electronic components , The cost of production is high, so the price is more expensive. In addition, the nominal current value, regardless of any power supply has a certain internal resistance, so when the power output current, the internal pressure drop will occur, resulting in two things, one is to generate heat, so the power will be hot, and the other One is to cause the output voltage to decrease, which is equivalent to the internal consumption.

Q: My computer is bought at the end of May this year, the power adapter has been no problem. But the day before yesterday in the speed of the sudden sound of crackling, like static, careful one, there is the friction of the pointer rotation. Probably intermittently lasted five minutes, and later returned to normal. But in the second boot, after about an hour this situation appeared, also continued for a few minutes before the shutdown did not appear. I checked it, which is related to capacitance, voltage, frequency. Also, when this sound is found, my power adapter is not plugged into the plug, and my battery is removed, is this also a relationship? I would like to listen to professional analysis, do not and I said to the repair station, if so I asked what? I just want to know about the specific circumstances, if not much impact, or can solve their own, do not have to repair. Thank you: With the adapter of the capacitor, there are generally two reasons, the adapter damp, and recommended dry hair dryer. There is a possibility, that is, the adapter collided, which loosened, and this situation will change the adapter, and to prevent short-circuit burned the computer. The way to tell you a little power knowledge, to prevent deceived: << usually imitation of the 20-50 dollars, renovation of the original 60-150, the real original in the 150-200 between the general, and the national security >> Need a laptop power adapter friends can go to my store to see, there are Genius original brand adapter, with the original original quality of the original, compared with the replica with the refurbished much stronger, and the price is cheap. Click on my name - login my image on the website - into my Taobao shop, you can view the details, we want to help.

Q: Why laptop power adapter do so big can not make mobile phone so small?: Because the notebook circuit complex and sophisticated, variable brain pressure device to prevent the circuit burned

Q: What is the order in which the power adapter is connected when the notebook is powered on?: First connected to the computer power supply. This protects your adapter from growing life. Also good for computers.

Q: Is the laptop's power adapter broken and you can buy other brands?: Yes. But with the original power adapter specifications, or may be a problem. 1, view the original power supply label on the specifications. Such as how much voltage output voltage, how much current. Calculate its output power, such as power = output voltage X output current, so be aware of; 2, the purchase, in addition to pay attention to compare the output voltage and current parameters, the connection with the books of low voltage DC plug specifications, but also special attention. Because the books have a variety of different specifications of the power interface design, different manufacturers of products, different interface is very natural; 3, big brands are preferred, do not buy low-cost compatible power supply. Because of its use of materials, work reasons, poor quality, a high probability of problems. It is broken little meaning, ruined the computer, get lost.

Q: Laptop plug in the headset has a current sound is the power adapter how to solve the problem: Should be the power adapter to connect the socket, there is no ground wire, to find a grounding cable on the OK, and some home decoration may not do ground

Q: As if the output are rated voltage rated current without affecting the use What is the principle of this? What circuit is used to achieve?: Range 110 to 120, the transformer has the ability to adjust.
