The market also sold Universal adapter, compatible with more than 90% in
However,
if the adapter using a non-original equipment, such as general purpose
transformers and the like, the problem can not be seriously considered,
then users can only try to think of ways to supply parameters to obtain
compatible. However,
the internal resistance of each adapter is different, the nominal
voltage tolerance may be different, under the nominal current output
voltage range may be different, and even output ripple factor is not
small enough not necessarily.

If
not carefully measured the output power of the relationship with the
output voltage, in principle, there is a certain risk, but this risk is
small, because if you choose a large enough power supply to the nominal
current of resistance will not have big problems, pattern wave coefficients can also be regulated to reduce the internal books. So,
while the first wife is indeed the power supply is better than
non-first wife, but the choice of the output current of the larger
non-original equipment supply, usually no problem.
* Summary:
In
this article, we discussed the daily maintenance of notebook power
adapter, working principles and causes of fever, and note the time
change and so on. Seemingly ordinary power adapter, the original has so much knowledge. Users
already have books, be sure to take good care of it oh Otherwise, if it
strikes, the laptop loses its source of power, will soon become a pile
of scrap metal.

If you need to temporarily borrow the power of other brands, to try to choose the same or greater output current adapter. If
the intention to buy a new, first wife of natural power is the most
ideal choice, but if you want to save money, then a solid work, the
output current of the larger non-original equipment power can be
considered.
