Laptop power adapter, the original 19v 3.95A can be replaced by 19V 3.42A it?
Rated current is not enough, if the latter quality is good, it is estimated that can be used, but the fever is high and easy to damage, temporary emergency can, but long-term use or recommended current equal to or greater than the original current adapter as well.
No problem, I and my students interoperability, we are ASUS, X42J model, his voltage is 19v 3.95A two I was 4.47, with the basic nothing, that is, the charging time can be normal Finished, the time to extend it.
Not the case will damage the notebook Once the hard disk motherboard failure is not a power adapter, but 19v395a can change 19v342a and 19v342a can not change 19v395a if there are multimeter oscilloscope, etc. You can test their own power supply constant voltage
As long as the voltage can be used as the same, but you change the 3.42A adapter must ensure quality, otherwise the notebook is not good
According to experience: 19 * 3.95 = 75W 19 * 3.42 = 65W The output voltage of these two adapters, so the computer light load (that is, the power consumption of the computer is not too large) is the case can be universal. The difference is that they can provide the maximum power is not the same, a maximum output to 3.95A current, one can output to 3.42A. In fact, 3.95A, 3.42A, are its nominal current, in fact, their Tolerance is 20% to 20% will be top of their OCP (overcurrent) protection. In other words, 3.95A may output to 3.95 * (1 + 20%) A, 3.42A the same. But in the case of heavy load, 65W may be the first to the top of the protection point, which occurred protection. Similarly, 65W heat is also higher.
There are many protective mechanisms for the notebook, so there is no important work that can be generic. Motherboard itself has over-temperature protection, over-current protection, automatic frequency protection. The adapter itself also has overcurrent protection, over temperature protection, low voltage protection.
In summary, can be common. However, it is best to use the battery together. If the supply of 65W is insufficient, there will not be a forced power off. In case of underfill, you will see that the charging lights on your computer are flashing, and you can unplug the adapter, re-insert it, and use it. Rated current is not enough, if the latter quality is good, it is estimated that can be used, but the fever is high and easy to damage, temporary emergency can, but long-term use or recommended current equal to or greater than the original current adapter as well.
