Are laptop power supplies interchangeble?

[rudder]

I've got a Gateway solo computer with a dead PS. The gateway power supply outputs 19v at 2.64A. I've got another laptop power supply from HP that outputs 19v but 3.16 amps. i've interchanged power supplies on components that take milliamps sometimes going from 800 to 1000 and know that it doesn't cause any problems. Should I just cave in and spend $40-50 on a new power supply?

First thing to consided is if the voltage is identical, in your case yes. Second, make sure that the AC adapter will supply enough amperage, 3.16A is more that 2.64A so yes. After the power requirements are met, then you can worry about whether the plug actually fits into the laptop correctly. The only problems I have ever seen from having too many amps is that a laptop would have problems charging the battery while the laptop was powered off.

it should be ok. HPs power supplies are compatible connector with some toshibas also. 19v 3 amps is a common supply now

1. spec wise, its fine.

2. Check the polarity! some use center negative and some use center positive despite using the same plug, failure to do so can fry the lappy.
