- Q:The notebook power adapter flashes
- 1: Check the socket with a multimeter is normal, the supply voltage is 220V. If the utility voltage is not normal, it is recommended to replace the use of environmental testing. 2: Check with the multimeter whether the output voltage and current of the power adapter match the label. If the gap is very large, and the mains voltage is normal, you can determine the power adapter failure, need to replace the laptop power adapter. 3: If the above check is normal, remove the laptop battery, do not external adapter. Press and hold the notebook power button 5 seconds to repeat 3 times. After releasing the notebook residual charge, insert the power adapter separately, power on the test. 4: If the fault persists, check the notebook's power connector, whether the exception. Such as loose or the appearance of damage and so on. 5: the above checks are normal, basically can be a preliminary judgment is the notebook motherboard failure. Recommended repair service station.
- Q:Is the laptop power adapter high temperature normal? Is there anything else?
- Hello, the power adapter because there are a lot of electronic components so hot is normal, the general hand feels hot does not feel hot on it, if hot, then there is a problem.
- Q:Lenovo laptop power adapter side of the feet which is positive
- Power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, generally by the shell, power transformer and rectifier circuit, according to its output type can be divided into AC output and DC output type; by way of connection Divided into wall and desktop.
- Q:Laptop power adapter output voltage is not the same as the current? What's the effect?
- I would like to elaborate on the basic principle of the large standard current power supply can replace the small standard current power supply. Some friends have misunderstood, that a large nominal current power will burn books, because the current big thing. In fact, how much current in the same voltage depends on the load, that is, the work of the books, when the books of high-load operation, the current larger, the books into the standby time, the current is smaller, in short, On the voltage divided by the equivalent resistance of the books. Large nominal current power supply has enough current margin, will not be replaced by a small standard current power supply after the overheating or output voltage is too low. On the contrary, with a small current power supply instead of high current power on the existence of the above risks. But some friends with 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,
- Q:Taian inverter 3.7KW 380V with 4.0KW 2 pole motor 18000 to 300HZ can it?
- The existing Taian inverter 380V3.7KW can bring 4.0KW 2 pole motor, 18000 to 300HZ can also see how you load, It is best to check your wiring tightness and whether the load is stuck. It is recommended to use the N310-4005-S3 this model, such as with the E510-405-H3 better.
- Q:Is the laptop power adapter hot?
- Third, the power of the nominal voltage than my books the battery voltage is much higher, not an accident, right? 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.
- Q:Three-phase two-pole motor can be used to reduce the frequency of the inverter
- With the electromagnetic governor can be, cheap only 50 yuan or so
- Q:Is the laptop power adapter long-haul?
- As long as the power, regardless of your access to the computer, the adapter is working. In fact, not much harm, anyway, five years of notebook life, this thing as long as not deliberately to damage, will be very durable, worse than the important parts of the computer slow. As long as the big brand, nothing Even if you broke, this thing can value a few money? In fact, the proposal or pull it, on the ground stumbling ... ...
- Q:The laptop's power adapter can be used on a desktop computer
- First of all, the desktop is the kind of power, is ups uninterruptible power supply. But relatively large, not directly inside the chassis. In addition, the storage capacity is limited.
- Q:Laptop power adapter in the ring is how is it?
- Inductance and capacitive shock sound In fact, any inductance and capacitance work will be shocked, but some shocks are large, and some shocks are small, the frequency is not the same, and some sounds harsh, some not harsh, and some ears can not hear the range Inside. Of course, this noise also has a certain standard, in fact, listen carefully, a lot of more power consumption of electronic equipment (tens of watts or more) have a voice. So, as you said to hear the sound is very small, sharp degree is not the same. This do not control, as long as they can endure, the general sound is not great, rest assured that good use of the performance and stability of no effect.
