Interchanging power cables of varying specifications between laptops?

post #1 of 4
Thread Starter 
My new laptop came from america today (dell inspiron 11) and the first thing I noticed was I forgot the cable doesn't fit into australian sockets. No problem I thought, I'll just use the cable from my old hp that no longer works. I read the specifications and discovered the 2 cables are rated for different amps. Then I realized that the cable I was using in the hp was also a replacement. So when I got the hp from america I found a cable from a different laptop, plugged it into the power brick and used that. So now I'm wondering if the reason the hp stopped working after about 6 months is because I've been using the wrong cable for it! Is that likely?
I suppose my first question will answer the second, if I can use that "old" cable with the new dell?

"old" cable - 2.5A 250V
Dell generic cable - 7A 125V
Dell power brick - INPUT: 100-240V 1.6A 50-60Hz OUTPUT: 19.5V 3.34A
HP power brick - INPUT: 100-240V 1.4A 50-60Hz OUTPUT: 19.5V 2.31A

Can't find the original hp cable at the moment but I'm guessing it had different specifications to the old cable.
Thanks in advanced

If the output voltage is the same and the connector fits it should be fine.

It doesnt matter the australian cable is rated for less amps? Doesnt that mean it cant power the laptop properly or damage the battery? Sorry not that i dont trust you, i just want to make sure I dont fry my new baby tongue.gif

Yup! This is absolutely correct.

The output voltage is what matters most. If it's less, the battery could charge improperly and read wrongly. If the voltage is too high, it could damage the battery on a physical level.
