Q:Is the desktop adapter's power adapter and laptop power adapter common?
As long as the interface, the output voltage and current, you can use, otherwise no
Q:HP notebook different models can be mixed between the adapter?
Basically can be, will not damage the charging adapter, but if the difference between the two charger parameters will be too bad for the battery, will affect the service life. For example, if the two books are equipped with a separate graphics card plug can be used, with a video card charger wattage than the integrated graphics to most of the same wattage and large wattage of the charger with a small wattage Of the books can be.
Q:Dell laptop adapter flash, but can not charge how to do it?
1, with a multimeter to check whether the normal socket, the supply voltage is 220V. If the utility voltage is not normal, it is recommended to replace the use of environmental testing. 2, with a multimeter to check the power adapter output voltage and current is consistent with 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 notebook 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 remains the same, check the notebook's power interface, whether abnormal. Such as loose or the appearance of damage and so on. 5, the above check are normal, basically can be a preliminary judgment is the notebook motherboard failure. Recommended repair service station.
Q:The power adapter light turns off after connecting the notebook for a few seconds

Q:HP laptop power adapter drip, can not charge, suspected to be bad.
I suggest you open the power adapter to see where it should be off the welding, contact is not on, welding just fine!
Q:Newly bought power adapter input current than the original large, can you use it?
Can be used, no problem. For the power supply, in general, the output voltage of the same circumstances, the output current can replace the output current is small, and the output current is small, you can not replace the output current. This is because, replaced with a larger output current power supply, the power load becomes smaller, the power of the heat will become smaller, increased reliability; and if the original design specifications of the power supply into a smaller current, Then the power load will be higher than the original, heat will increase, the reliability will be reduced. So, your situation should be no problem.
Q:Laptop plug in the headset has a current sound is the power adapter how to solve the problem
Notebook computer plug in the headset with a current sound If the problem is the power adapter can be resolved as follows: 1, if the power adapter when using the power supply when the headset noise, then the power adapter filter effect is not good, you can replace a power adapter to use. 2, you can buy a power filter, the power lines in the unwanted harmonics clean and then through the power adapter will reduce or eliminate noise. 3, in the audio settings which will turn off the volume of the microphone or mute will reduce the noise composition. 4, in the audio settings which will adjust the volume of the waveform adjusted to the middle position, reducing the total volume of the noise amplification.
Q:Laptop adapter voltage battery voltage is not it can be charged to the notebook? Influential?
Select the charger is not simply higher than the laptop battery can be, there is a limit, generally not more than 10%, that is, the books 14.8 battery, it is recommended to choose about 16V mobile power is better, although the charge may be slow Point, but the slow charging effect is the best. Of course, 19V can also be used, just not recommended.
Q:Laptop power consumption is 117 watts but the power adapter is 90 watts what the situation?
Laptop power consumption is 117 watts generally refers to the maximum power consumption, this is only all the hardware settings at the same time when the power consumption, but in fact all the settings at the same time to achieve the maximum is unlikely, generally 60-80% Is the actual use of the maximum value, the manufacturers are often repeated under the test to determine the power adapter power, is to ensure that the normal work of the laptop (usually about 20% margin) set the capacity, so large Do not have to be tangled for this. Now the power adapter power is rated power, the general instantaneous reach of the power will be more than +20%, but also to meet the normal needs of normal work.
Q:Original notebook power adapter burned out, the current is the original 3.95A is equipped with 4.74A, you can use it?
This is no problem, the voltage can match
