Usually the power adapter is faulty, it is best to re-purchase one; There are two main indicators of the adapter, namely: voltage and current, and the voltage and current for each notebook is not the same, the configuration or purchase must pay attention; In the notebook's manual or "specification range" or "electrical parameters", generally indicate the basic parameters of the adapter, the most important of which is the voltage and current, if there is no original adapter, you need to find alternatives, we must choose: 1, the new adapter of the voltage and the original exactly the same; 2, the current should be slightly larger than the original maximum output current (20 ~ 30%); 3, the positive and negative polarity of the adapter plug must be the same as the polarity of the socket (ie, the original adapter) 4, the hole diameter of the plug must be the same as the diameter of the socket (ie, the original adapter) (the plug has a large hole and hole points).

If the replacement is not normal, there may be a problem with the power control board. Laptop charger (Laptop Charger), that is, laptop charger. The traditional notebook charger can only output a single voltage to a type of notebook computer charging, the industry called the traditional notebook power adapter for the single band notebook charger (mainly in order to distinguish between the universal notebook charger.)

Q:What about the Oneda Laptop AC Adapter? Not used to bypass

Oneda laptop power adapter wire high hardness, ultra-thick copper core, to avoid easy to break, to ensure efficient transmission of current stability, strong quality, uncompromising attention to the use of the world's leading factory production process, the import of components, power output power, High precision, low voltage ripple, stable power supply, exclusive OCP OVP OTP SCP multiple protection, to ensure safe and stable performance,

Q:Recently bought HP's 4416s notebook, but when used to find the power adapter will issue a creak sound, looked at other people's notebooks seem to have no such obvious squeaky. Looked with their own model almost HP notebook, although there are creak of the sound, but it seems not my voice big. Someone explained that this is the current work when the sound or the town ...

1, the power adapter power normal use of the process, in a quiet environment or close to the power adapter can hear a weak current sound, this phenomenon is normal; 2, if the current sound is more obvious, the impact of normal use, the power adapter may be the impact of hardware operation, the proposed repair or direct replacement. The power adapter in the conversion of the power supply will inevitably send a fixed frequency of the sound, different frequency of the inductance coil because of its rated power is not the same, so the induced current of the sound size is not the same, there will be creak sound.

Q:The laptop adapter can be charged but can not be powered on separately

This question is very simple ah! Is your laptop battery failure, to find a master to help you look at the post! If the warranty period they will help you replace the free! Thank you for adoption!

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?

But be sure to pay attention to whether the output voltage of the adapter and the original with the same.

Q:Apple laptop power adapter bad how to do it

Fifth, check the capacitor resistance inductance with or without problems, such as capacitor drum package, the best timely replacement, so as not to leave hidden dangers. The above is the power adapter maintenance of the five steps, through these five steps, you can check the power adapter. Of course, if there is no big problem, it is best not to easily open the shell, if necessary, it is recommended to find a better professional protection.

Q:My home is ASUS U3S. Input / input / output: + 19V ==== 4.74A, 90W. Then I use the same voltage as the power adapter is the charger. (Input / output INPUT: 100-240V-1.6A (1.6A) 50-60HZ This is the first, this is the following: (OUTPUT: 19V === 3.42A (3.42A) 65W should see the first few, The beginning can also play, play a few days to open the machine to open the same half of the automatic cassette and restart, safe mode can be opened, U disk mode can also open, repair the computer that is the graphics card may be broken, the temperature was Lu Master 70- More than 80 degrees Celsius. Is not the notebook I was playing bad?

This may be used to ruin the hardware, it is recommended that you quickly switch back to the 90w adapter.
