How to Test your dell AC Adapter

Many electronic devices these days require http://www.laptop-adapters.com.au/dell/dell-inspiron-6400-ac-adapter. When you charge your phone, you’re using an AC adapter. If you have computer speakers, they are probably powered by an http://www.laptop-adapters.com.au/dell/dell-studio-1535-ac-adapter.Needless to say, AC adapters are everywhere, and they power many different forms of electronic devices.

If you are faced with a device that won’t work (e.g., won’t turn on), yourhttp://www.laptop-adapters.com.au/dell/dell-inspiron-6000-ac-adapter may have failed. You could try another adapter with an identical voltage output, an identical plug type, etc., but what are the chances that you’ll have an identical adapter? Unless you collect power cords for some bizarre reason, your chances at finding the same type of adapter would be slim. You could also test the http://www.laptop-adapters.com.au/dell/dell-inspiron-1720-ac-adapter in another device requiring the same voltage, but it’s not likely that you’ll have a device requiring that type of adapter either. So, what’s left?

The option you’re left with is significantly more reliable, since it provides actual quantitative data. If you have a multimeter, it’s not hard to test an http://www.laptop-adapters.com.au/dell/dell-studio-1737-ac-adapter for its power output. If you don’t have a multimeter and you’re diagnosing computer or other electronic devices very often, you might want to get one. They come in handy for a lot of things. Anyways, back to the testing part of this post.

First, you want to figure out what you want to set it for. If you’re testing anything that charges a battery or runs a laptop or speakers, you’re going to have DC output. That means you want to set your multimeter for testing DC current. When setting what voltage to detect, I always air on the side of caution. For example, the other day when I tested a http://www.laptop-adapters.com.au/dell/dell-inspiron-1525-ac-adapter rated for ~13 volts, I decided to test it on the 200V setting instead of the 20V setting. Why? Adapters that are functioning normally can put out voltages higher than what they are rated for. If it’s not working properly, who knows what kind of voltages it’s putting out?

Finally, the actual test. Make sure your adapter is plugged in. Then, stick the positive (red) probe into the circular opening in the plug. Put the ground (black) probe on the on the outside of the plug (See the image below for an example of where to put the probes). Then observe the reading that displays on the display (usually digital). If the reading is very close to the voltage it is rated for, your http://www.laptop-adapters.com.au/dell/dell-inspiron-15-ac-adapter is good. The voltage can even be about half of a volt higher than what it’s intended to put out. However if the output is zero or significantly lower than the intended voltage, your adapter is bad.Insert the red probe into the plug, and touch the black probe to the outside of the plug.
I hope this guide helps you. If you have any problems with testing an http://www.laptop-adapters.com.au/dell/dell-inspiron-1520-ac-adapter, let me know and I’ll be glad to help.
