Open your computer to find the motherboard. A multimeter allows you to understand what is going on in your circuits. Test your multimeter is working by pressing the probes together. Use a multimeter on these test points to see if the voltage measured matches the labeled test point voltage. Start by setting the multimeter to the ohms scale usually represented by the greek letter ω omega.

You simply dial the proper function and scale touch the two test leads to the wiring or device in question and check the meter reading. The multimeter screen should read 0 00 also known as short circuit inexpensive meters may read close to this from resistance of their leads. Even if you don t have an electrical schematic of the circuit board which would identify components and give you the voltage and resistor values that should be present many circuit boards have test points that are clearly labeled. Once you do that test it with the chassis to ensure that it is still zero. Bring out your multimeter and adjust it to the lowest setting.

Find the two connections where wires connect to your part.
