Choosing the correct Laptop AC Adaptor is all a matter of voltage, output power, and proper connection.

1. The first thing  to consider in a notebook ac adapter is the voltage. The easiest way to check this is to turn the computer over and see if there is a voltage listed anywhere on the bottom of the machine. A sticker may be affixed with this information and other similar laptop specs listed. It should be a number with a V such as 19.5V. This information is also available on the original adapter. The Voltage must be within 10% of your original AC Adapters Voltage. 

2. The second thing  to look for is the current output needed for the laptop ac adapter. Just for example, it may say something like 4.7A, 950mA etc. This number will ensure that the power going to your machine will be acceptable and keep it operating normal. Not paying attention to either of these numbers could cause the electrical systems in your laptop to malfunction and stop working altogether. The Amps may be higher but they cannot by lower.

3. Once these two issues have been settled, the other important step is simply to make sure the laptop ac connection fits the port in your notebook PC. The voltage and output current of the laptop ac adapter will not matter if it is not able to be connected.
