laptop psu tester

do you guys know of a "laptop power supply tester" ?
thanks.

A multimeter

ok, i guess am gonna have to learn how to use one, isn't an easier way like those pc testers ?

Laptop connectors are not standarized like the ATX formfactor. Pretty much every model has a different physical connector.

Basically all you need to do is get a multimiter, set it to DC volts, and start probing the connector. The sticker on the transformer will tell you what voltage you should be getting.

If the connector has 2 pins, thats easy - one is positive and one is negative. If you put your probes on the pins and you get a negative voltage reading (or the needle pegs backwards) it just means you have the leads reversed.

For connectors with more that 2 pins, it's trickier. Unless you can find a pinout, you will just have to poke around.

thanks lucassix, i will get one and go over the instructions or look for a "mulitmeter tutorial" on the web.
thanks again
