If you have two laptops from the same manufacturer, can you interchange their
power sources? One of my laptops has a lighted AC adapter tip and one doesn’t.
Can I use the lighted adapter on the non-lighted?
In this excerpt from
Answercast #26, I look at various power supplies that can safely be
Interchanging power supplies
My belief is yes.
Now, I have to throw out the usual caveat that you should double check the outputs of the power supplies that you’re talking about and make sure that they are the same voltage.
What you’ve described is, in fact, exactly what happens here. Over the years, I’ve had several Dell laptops (and one of the reasons that I like the Dell laptops is that they all happen to use the same power supply plug). After the laptops have gone on to a higher plane, the power supplies remain behind.
So, I have this nice collection of power supplies:
They all have the same tip;
They all put out the same voltage;
And I use them interchangeably.
In fact, some have lighted tips: the newer ones do and the older ones do not.
So, with a certain amount of caution, I’m going to say that sure, it should be fine to do exactly what you’re doing: as long as the power supplies are indeed the right voltage, all the same voltage, and all from the same manufacturer.
