Help, I have a Gateway MX644 laptop. My dog bit through the power supply cord, and I went and bought a new one, a Targus universal which has an output amperage of 4.74A, and input of 1.5A. The old one had an output of 3.43A, and input 1.7A. Can I use it? What is the difference anyway between output amps and input amps? I'm useless at this sort of thing, just don't want the computer to blow ... any ideas? :(

Go to Targus's web site or call them, give them the model number of your laptop and the adapter you bought... they will tell you if it works.
Input and output... Are exactly as they sound. In the case of a laptop, your input (from the plug on the wall) and output (to your laptop). Generally speaking, in North America, your wall socket puts out 15 Amps. Your input Amps come into play when you start thinking of plugging into your car, boat or a plane for example. You need at LEAST 1.5Amps for your new adapter to work.
Just because your wall output has 15 Amps, does not mean, that your adapter needs 15 amps.
What you really need to worry about, is that the plug looks and is the exact same. You can do this visually. However, polarity and voltage/amps dictates if it will work. It looks like your amps are okay, but your voltage should be the same (or very close). The polarity... is different. If you look at the flug that you push into your computer... It will have a Positive and a Negative... It's usually not marked. In many cases, the plug should be round with a hole. In the case of the whole, you need to make sure you are using the same polarity... is the "hole" positive or negative? Sometimes, the laptop has a little drawing... or so does the adapter... Looks like a letter "C" with a dot inside or a "C" with a dot slash. It usually have the Voltage (V) and a + - on it, indicating if the inside hole is positive or negative. They need to be the same. Your new adapter, if the right one, should be the same.
Good luck... again, check out their web site (assuming you have power to do so!)

What you need to be careful about is voltage.
Amps just means the amount of current you can pull.
If the amps are higher than it doesn't matter. If the output voltage is higher than it will probably cause damage.
If the voltage is lower it could cause some unexpected results and maybe some damage.
Make sure the output voltages match and the amount of current(amps) the power supply can pull is higher than the old one.

hi, I comprehend that AC adapter in no longer charging the computing gadget yet once you carry the pin of the adapter that is going into the computing gadget at an attitude it is going to cost. if it rather is the case then i'm afraid the charger slot on the computing gadget is malfunctioning. in this regard, in the adventure that your computing gadget continues to be below guarantee you touch the producer help they'll fix this.
