Do you know what the precautions of power supply are?

Are the same nominal voltage power supply, output current is different, can be used in the same notebook?

Same power supply voltage, different output current, can be used in the same notebook.

The basic principle is that a supply of high nominal current can replace a supply of low nominal current.

How much current depends on the load at the same voltage. When the book high load operation, the current is large, the book into standby,

the current is small, large nominal current power supply has enough current margin.

On the other hand, some with 56 w power instead of 72 w, there is no problem with it,

the reason is that the design of the power adapter with certain margin, usually load power is less than the power,

so that instead of in general use is feasible, but the rest of the power supply power margin is very little,

once you pick up a lot of peripherals, estimate, it will be dangerous.

So it is best not to use a low-current power supply instead of a high-current power supply.
