Q:My Lenovo v450 laptop power adapter should be bad how to match?
Hello, this is not recommended to go online to buy. The original is too expensive, generally with the domestic voltage instability may occur, so I suggest you go to the computer city to buy. Generally good quality, to about 120. The The As for the model, you can look at the output power, or you take your bad adapter to go, people see a look. The The The You can use a few years no problem, power adapter this kind of thing, online to buy the replacement is not convenient. The Hope to help you
Q:How does the spindle drive system of the inverter realize the positive and negative control of the main pole?
The general inverter has an external terminal control and communication control two modes optional, select one of them can be completed ah
Q:My laptop can not use the power adapter, and can only use the battery, how is it ah,
1, laptop power adapter can not be used, first check the power outlet, plug, cable has no virtual state, if you can tell the normal equipment damage. Should be repaired. 2, the laptop battery must be charged through the power adapter or directly for the computer power, the power adapter is not missing, if you have experience can turn on the power adapter to see if the fuse is broken, try to update the fuse can be restored. If the integrated circuit is damaged, only updated.
Q:On the laptop power adapter problem
Notebook power on the two specifications, one is 65W, one is 40W, 65W power supply is a discrete graphics notebook, 40W is integrated graphics notebook. Just connected to the use of power, then there is no problem. Just if you laptop battery with the light of the words, plug in the power can not be the same as with the 65W, immediately you can use the boot. Because the current is low, the charging speed is relatively slow. The other will not have any effect
Q:Pump frequency converter instantaneous restart and restart the problem
Speed tracking start. The specific to ask you to drive the inverter that guy. He earned your money there is a need for technical support
Q:Laptop computer about electricity no electricity, is the power adapter problem?
To judge this is very simple: 1. The computer is in the battery state to see if it works properly. If it does not work, the battery has a problem 2. Remove the battery from the computer with a power adapter to see if it is working properly. If not, there is a problem with the power adapter 3. If the two states can work that is the computer charge management part of the poor contact and other issues.
Q:Can the laptop 1.3a power adapter be used on a 1.5a device?
No, use a power adapter that is equal to or slightly larger than 1.5a.
Q:Why G120 inverter to be equipped with 4-pole motor?
Not necessarily must be equipped with four-pole motor, 2 pole, 6 pole, 8 pole, 12 pole can be used. As long as there is no problem with attention to current matching. Because the amount of 4-pole motor is the largest, all the frequency converter, are based on 4-pole motor for the control model design.
Q:Please recommend a high performance laptop power adapter?
See what model you notebook ah, according to your power adapter voltage, rated current to match.
Q:Laptop power adapter problem
Third, since the book is very old, the original factory may not have such a transformer spare parts, then a reasonable idea is to let this book off, rather than the provincial money to take their own little life joke, a notebook and then expensive It will not be more expensive than your life, the money is very unreasonable province. A notebook with a decade is also completely considered the best use of the matter, you are stingy stingy Ye Hao, there are emotional sustenance worth mentioning, it should be eliminated or out of it.
