Check Laptop Motherboard With Multimeter USA 2021 – How to check Laptop Motherboard with a multimeter
The device that we rely heavily upon for our day-to-day work, communication, entertainment or leisure is the laptop and since it has become an integral part of our lives, it is obvious that we will face some or the other issue with it. The processing of information and operation of different tasks in a laptop is taken care of by the main printed circuit board called a motherboard how to check laptop motherboard is working or not which is also present in other general-purpose computers and expandable systems.
Many important components, such as the core processing equipment how to check motherboard voltage and the memory are maintained and communicated with, and connections for additional peripheral components are provided to the system with the help of the motherboard which is the most crucial component of the CPU. Since all the important functions are carried out by the motherboard or with its help, it is imperative that we keep a check on it to ensure everything runs smoothly Read more about Check Laptop Motherboard With Multimeter USA 2021
A faulty motherboard will cause your main device to stop working since it includes all of the components required to run a computer or a laptop. To avoid major disruption in the working of your device, diagnosing the motherboard by yourself may be quite beneficial. A multimeter may even be used to test a motherboard at home. how to check dead laptop motherboard (step by step) pdf You might probably be wondering what a multimeter is. To understand about this device, we must first comprehend the requirements for motherboard testing.
Check Laptop Motherboard With Multimeter USA 2021 Why we should test motherboard at home?
The first thing a technician examines when there is an issue with a CPU component is whether the motherboard is alive or not. Even if the motherboard is in great working order (on occasion), the technician may claim that it is dead in order to make a large fee. He might first sell your original and used motherboard, which is technically yours, and then charge you a fee for installing a new one. He will also be in charge of inspecting the components and determining the root cause. how to check voltage in laptop motherboard That is why it is important to know how to examine a motherboard at home, which can be done with the help of a tiny electrical device known as a multimeter.
What is a multimeter?
A multimeter is a device used to measure various electronic characteristics such as voltage, current, and resistance. It is more useful while utilising or constructing a circuit. It may appear tough to operate a multimeter at first, how to test laptop charging port with multimeter but after you start using it or follow our instructions, it will become second nature.
The multimeter’s centre includes a knob that is used to switch between and test various electrical characteristics. The properties are tested by turning the knob to choose that property (for example, resistance) and connecting those two wires (which are connected with the multimeter) to the part of the component which needs to be diagnosed.

- Turn off and unplug the computer.
- Wait a few minutes for it to cool completely and lose its charge.
- Take out your multimeter and set it to the lowest possible setting. Typically, this is 200 Ohm. You must tap both leads together to get the metre to zero. After that, check it with the chassis to make sure it is still zero.
- To find the motherboard, open your computer’s CPU. The ATX connection should be removed.
- The red wire connects to the AC ground pin on the PSU, while the black lead remains connected to the chassis. The DC connection should have the black wire pins. Even now, all the measurements should be zero.
- Now, while keeping the black lead in place, check all the coloured wires with the red lead. It is considered typical to have a score of 50 or higher. Anything under 50 is a cause for worry.
- Furthermore, you may check for problems. Remove your system from the motherboard entirely. For pin numbers on your motherboard, see the ATX 20 pin diagram available on the internet. To test each GND pin, use the red lead. Third, five, seven, 13, fifteen, seventeen must be nil. There’s an issue when you notice some other reading.
